In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has shed light on the neurophysiology of altered states of consciousness induced by classical psychedelics, such as psilocybin and LSD, whose effects are mainly mediated by agonism of serotonin receptors. Few attempts have been made (...) at bridging these two domains of inquiry, despite intriguing evidence of overlap between the phenomenology and neurophysiology of meditation practice and psychedelic states. In particular, many contemplative traditions explicitly aim at dissolving the sense of self by eliciting altered states of consciousness through meditation, while classical psychedelics are known to produce significant disruptions of self-consciousness, a phenomenon known as drug-induced ego dissolution. In this article, we discuss available evidence regarding convergences and differences between phenomenological and neurophysiological data on meditation practice and psychedelic drug-induced states, with a particular emphasis on alterations of self-experience. While both meditation and psychedelics may disrupt self-consciousness and underlying neural processes, we emphasize that neither meditation nor psychedelic states can be conceived as simple, uniform categories. Moreover, we suggest that there are important phenomenological differences even between conscious states described as experiences of self-loss. As a result, we propose that self-consciousness may be best construed as a multidimensional construct, and that “self-loss,” far from being an unequivocal phenomenon, can take several forms. Indeed, various aspects of self-consciousness, including narrative aspects linked to autobiographical memory, self-related thoughts and mental time travel, and embodied aspects rooted in multisensory processes, may be differently affected by psychedelics and meditation practices. Finally, we consider long-term outcomes of experiences of self-loss induced by meditation and psychedelics on individual traits and prosocial behavior. We call for caution regarding the problematic conflation of temporary states of self-loss with “selflessness” as a behavioral or social trait, although there is preliminary evidence that correlations between short-term experiences of self-loss and long-term trait alterations may exist.

We present a model of similarity‐based retrieval that attempts to capture three seemingly contradictory psychological phenomena: (a) structural commonalities are weighed more heavily than surface commonalities in similarity judgments for items in working memory; (b) in retrieval, superficial similarity is more important than structural similarity; and yet (c) purely structural (analogical) remindings e sometimes experienced. Our model, MAC/FAC, explains these phenomena in terms of a two‐stage process. The first stage uses a computationally cheap, non‐structural matcher to filter candidate long‐term memory (...) items. It uses content vectors, a redundant encoding of structured representations whose dot product estimates how well the corresponding structural representations will match. The second stage uses SME (structure‐mapping engine) to compute structural matches on the handful of items found by the first stage. We show the utility of the MAC/FAC model through a series of computational experiments: (a) We demonstrate that MAC/FAC can model patterns of access found in psychological data; (b) we argue via sensitivity analyses that these simulation results rely on the theory; and (c) we compare the performance of MAC/FAC with ARCS, an alternate model of similarity‐based retrieval, and demonstrate that MAC/FAC explains the data better than ARCS. Finally, we discuss limitations and possible extensions of the model, relationships with other recent retrieval models, and place MAC/FAC in the context of other recent work on the nature of similarity.

We propose a distinction between precategorial, acategorial and categorial states within a scientifically oriented understanding of mental processes. This distinction can be specified by approaches developed in cognitive neuroscience and the analytical philosophy of mind. On the basis of a representational theory of mental processes, acategoriality refers to a form of knowledge that presumes fully developed categorial mental representations, yet refers to nonconceptual experiences in mental states beyond categorial states. It relies on a simultaneous experience (...) of potential individual representations and their actual “representational ground”, an undifferentiated precategorial state. This simultaneity is possible if the mental state does not reside in a representation but in between representations. Acategoriality can be formally modeled as an unstable state of a dynamical mental system that is subject to particular stability criteria. (shrink)

Various theories of moral cognition posit that moral intuitions can be understood as the output of a computational process performed over structured mental representations of human action. We propose that action plan diagrams—“act trees”—can be a useful tool for theorists to succinctly and clearly present their hypotheses about the information contained in these representations. We then develop a methodology for using a series of linguistic probes to test the theories embodied in the act trees. In Study 1, (...) we validate the method by testing a specific hypothesis (diagrammed by act trees) about how subjects are representing two classic moral dilemmas and finding that the data support the hypothesis. In Studies 2–4, we explore possible explanations for discrete and surprising findings that our hypothesis did not predict. In Study 5, we apply the method to a less well‐studied case and show how new experiments generated by our method can be used to settle debates about how actions are mentally represented. In Study 6, we argue that our method captures the mental representation of human action better than an alternative approach. A brief conclusion suggests that act trees can be profitably used in various fields interested in complex representations of human action, including law, philosophy, psychology, linguistics, neuroscience, computer science, robotics, and artificial intelligence.

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are (...) bound. Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. (...) class='Hi'>Mental strength has been largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

Recent scientific research into the therapeutic potential and mechanisms of psychedelic drugs raises intriguing and hitherto largely unexplored philosophical questions. A brief overview of the relevant science is given before addressing these questions. It is argued that psychedelic transformation is a distinctive psycho- pharmacological intervention because its mechanism of action ineliminably involves conscious mental representations, and thus is more transparent to the subject than the mechanisms of other drug therapies. This argument connects with issues in the philosophy of (...) (cognitive) scientific explanation. It is also argued that transformative psychedelic experiences may well confer three distinct kinds of epistemic benefits: knowledge by acquaintance of the subject's psychological potential, knowledge by acquaintance of the meta-physical nature of the (sense of) self, and revitalized capacities for the acquisition of modal knowledge. Non-naturalistic metaphysical and epistemological claims abound in psychedelic circles; thus, it is important to realize that psychedelics may yield naturalistically acceptable epistemic benefits.

The great task of cognitive science is to explain the phenomenal, first-person experience through the brain’s biophysical processes. This articles takes up this challenge by presenting the theory of how to reconcile the distinguishable properties of a material and mental processes. For this purpose, I describe how knowledge representations arise and how they can correlate with the emotions that accompany their formation. These associations can lead to first-person sense impressions, that is, qualia, which are the gist of phenomenal (...) awareness. I hypothesize that perception and consciousness and their causal role can only be explained by pointing to two aspects of consciousness: The event reporting aspect responsible for being aware of what is happening and the executive aspect responsible for the body’s actions and bodily responses. Both of these aspects are functionally accomplished by two separate neural mechanisms. Explaining the stream of consciousness required diversification of the concept of consciousness and the distinction of “executive” and “reporting” consciousness, respectively. Impression of feeling, a stream of consciousness, and a train of thought felt as conscious perception are the effect of stimulation of the lower sensory fields of the brain by feedback stimuli from upper cerebral areas. Subjectively perceived sequences of such recreated images only accompany brain processes but do not affect them directly. However, they are not objectively epiphenomenal since they modify the neural representations of knowledge embedded in memory and thus influence future states of consciousness.

In this thesis I investigate the notion of experience in German Idealist Philosophy. I focus on the exploration of an alternative to the transcendental model notion of experience through Schelling's insight into the notion of logogrif. The structural division of this project into two sections reflects the two theoretical standpoints of this project, namely the logic and the logogrif of experience. The first section - the logic of experience - explores the notion of experience provided in Kant's Critique of Pure (...) Reason, Critique of Judgement and Fichte's Science of Knowledge. I argue that Kant's fundamental question about the possibility of synthetic a priori judgements succeeds in thematising the aporia of cognitive experience but results in a subject-oriented, representational model which radically confines the notion of experience to the constitutive laws of the understanding or to the normative precepts of Reason. Experience is founded upon a sharp division between faith and knowledge, will and logic, desire and reflection, absolute and finitude. Fichte's endeavour to articulate a non-representational account of experience, does not succeed in extricating itself from the representational model, so long as experience is reduced to the ever-producing deeds of the self-positing ego. Despite the serious differences between Kant's and Fichte's notions of experience, both accounts, so long as they unfold from a transcendental standpoint, attempt to resolve experience into conceptual laws or determinations of the ego's absolute will. Experience is transformed into an object of the subject's cognitive or volitional faculties. The paradoxes of man's interaction with the world are intended to be accommodated either by the law-giving spontaneity of the understanding and the Architectonic of Pure Reason or by the overpowerful primordial act of the self-positing ego. This implies the conceptualisation of the self in terms of constant identity-through-time, or sheer self-determination. However, this conceptualisation remains at the normative or prescriptive level, which in turn is projected upon the world. The latter, though appears as the subject's property, essentially remains alien and opaque, confirming the radical limitations of the ego rather than its order-giving authority. Moreover, this notion of experience is ultimately founded upon a radical expulsion of the divine from the world, the de-spiritualisation of the sensual and the de-sensualisation of the spiritual, the sharp juxtaposition between absolute and finitude. This results in a self-defeating subjectivity, whose firm identity and rule-giving authority does not rescue it from its perennial unattainability to 'organise the conditioned' or 'conquer the unconditioned'. In Kant's and Fichte's thought, however, I detect elements that potentially transgress their transcendental account of experience. These are found in Kant's concept of spontaneity and free play between understanding and imagination, and Fichte's concept of productivity. I argue that these elements lose their potential dynamism, so long as they are absorbed by the transcendental demands for the solution of the aporias of logic. However, these elements point to the need for a radical re-conceptualisation of the notion of experience. This is provided by means of Schelling's logogriflic approach, which constitutes the theme of the second section. The second section - the logogrif of experience - attempts to articulate a different approach towards the notion of experience, through an exploration of Schelling's versatile and provocative thought. This section focuses on Schelling's original insight into the notion and act of logogrif, which opens the dialogue between logos and mythos, cosmic becoming and human soul, cosmic imagination and human reflection, faith and knowledge. This section attempts to illuminate Schelling's fascinating philosophical investigations and discoveries that have been rather overlooked, possibly, due to Hegel's overwhelming critique. This section, after a brief critical examination of the Identity Philosophy, attempts to elucidate Schelling's notion of experience through his middle works, Of Human Freedom, Ages of the World, The Deities of Samothrace, which are treated as a self-developing trilogy. Schelling re-addresses the aporias of logic not as part of Reason's self-interrogation but as part of the cosmic paradoxes and living experiences. In this way, Schelling resets the scene of the debate on the conditions of possibility for cognitive experience by putting on the stage the enigmas of the cosmos and life rather than the Tribunal of Reason. Logic itself is conceived as a potency in the cosmic becoming, and consequently can no longer attempt to establish the transcendental conditions for the possibility of cognitive experience. Cosmic becoming, in which man is an active part, is conceived as the process of the movement, the interaction, the transformations and transmutations of multiple potencies. These, far beyond any mechanical conceptualisation, appear as self-moving and yet interdependent, unknown yet familiar, inscrutable and yet manifest powers, describing the mystery of life itself. The latter is depicted as an ever-recurrent act of longing for self-expression as active unity. Experience is conceived as the lived process of a network of living potencies, which may not only resist rational powers but may also puzzle and seize them. In this context, reflection acquires a plastic dimension, as opposed to its rigidity in the representational model of experience. Reflection depicts cosmic longing's self-formation, whose man is part. This self-bending formation partially illuminates the nature of longing, and from this standpoint is the logic of the longing. However, this formation is movable, transmutable and mostly ineffable, and from this standpoint is the logic of a riddle: a logogrif. Logogrif is the transitive term that attempts to describe the transition of experience from its enacted phase to its allusive conceptual utterance, and in this sense the term itself participates in both phases, as both form of thought and form of life. The logogrific approach to experience in turn transposes us as from the realm of pure concepts to the realm of the mystery of life, from pure thought to acts of longing, from the Architectonic of Pure Reason to Cosmic Theurgy. The latter term attempts to grasp the paradox and dynamism of cosmic and non-cosmic becoming by means of multiple, vanishing and ever-recurring, transmutable potencies, or in Schelling's terms 'the magic of insoluble life'. Schelling's logogrific account consists in a powerful voice for the re-enchantment of the world, the introduction into the notion of experience of the imminence of the divine. This is not suggested in terms of the adoption of old religious doctrines but by means of the discovery and re-discovery of the theurgy of life, through the intensification of our artistic mood, the creative expansion of our deeds. This notion of experience allows for the reconsideration of the notion of the self, in terms of a dynamic, conflictual process between conscious and unconscious powers and the critical revaluation of the accounts of subjectivity which reduce it to the sphere of self-consciousness. The thesis concludes with the need for an investigation into the relation between logos and mythos, which only tangentially has been introduced by the present project. In this context it will be possible to re-appraise the potential that the logogrific approach opens for an alternative to both logical and traditional mythological patterns of thinking. (shrink)

Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue that there are, indeed, deeper commonalities. Recent empirical studies show that psychedelics and meditation modulate overlapping (...) brain networks involved in the sense of self, salience, and attention; moreover, psychedelics can occasion lasting increases in “mindfulness-related capacities” for taking a non-reactive stance on one’s inner experience (e.g. Sampedro et al. 2017). The self-binding theory of psychedelic ego dissolution (Letheby and Gerrans 2017) offers a plausible explanation of these findings: by disrupting self-related beliefs implemented in high-level cortical networks, both psychedelics and meditation can “unbind” mental contents from one’s self-model, moving these contents along the continuum from phenomenal transparency to opacity (cf. Metzinger 2003). In other words, both psychedelics and meditation can expose and weaken our foundational beliefs about our own identity, allowing us to disidentify with these beliefs and see them as “just thoughts”. There are connections between these ideas and recent arguments suggesting that psychedelic use may have epistemic benefits consistent with philosophical naturalism (Letheby 2015, 2016, 2019). I conclude with a proposal: these connections may help in thinking about the putative epistemic benefits of meditation practice from a naturalistic perspective. (shrink)

In spite of extensive research on theory of mind, lay theories about the unconscious have scarcely been investigated. Three questionnaire studies totaling 689 participants, examined to what extent they thought that a range of psychological processes could be unconscious. It was found that people are less willing to countenance unconscious processes in themselves than in others, regardless of the time period considered – present, past or future. This is especially true when specific experience-like situations are envisioned, as opposed to considering (...) the question in abstract or generic terms. In addition, the notion of unconscious psychological processes is resisted for certain domains in particular: intending, sensing, believing, and thinking. We interpret this pattern by positing the existence of two conceptions about the unconscious that are differentially applied according to circumstances: one originating in prevalent social representations about the unconscious, the other based on self-model of the person as an intentional actor.

This paper proposes a qualitative study exploring anomalous self and world-experiences in individuals with high levels of depersonalization experiences. Depersonalization (DP) is a condition characterized by distressing feelings of being a detached, neutral and disembodied onlooker of one’s mental and bodily processes. Our findings indicate the presence of a wide range of anomalous experiences traditionally understood to be core features of DP, such as disembodiment and disrupted self-awareness. However, our results also indicate experiential features that are less highlighted in (...) previous work, such as faster time perception and blurriness of the self/other boundaries which may play a key role in altering one’s sense of self and sense of presence in the world. Our qualitative study provides an in-depth examination of self-reported disturbances of one’s relatedness to one’s self and the world, thereby shedding further light on the nature of altered subjective experiences in DP. In doing so, this paper draws attention to key aspects yet overlooked that may prove valuable for shedding further light into the phenomenon of depersonalization. We conclude by highlighting limitations of this study and a number of open questions that further work needs to address in the future. (shrink)

The idea that there are ‘laws of nature’ is a widespread scientific opinion. On the one hand, I argue that this idea has the crucial function to explain the obvious similarities of physical processes. On the other hand, I show that this idea can be replaced by the hypothesis supporting that a minimal consciousness immanent to matter governs its processes. This latter hypothesis may seem surprising, but compared to that of laws, it is more empirical in the sense (...) that it is inspired by our conscious experience, in particular our experience of automatic actions. And it is deflationist, because it allows us to reject the existence of laws, which must be considered as Platonistic forms. This hypothesis has been supported by Peirce and Bergson. In this paper, I try to clarify and complete their views, and to draw the consequences for the study of consciousness. (shrink)

Emerging evidence is now challenging the view that patients diagnosed with schizophrenia experience a selective deficit in their sense of agency. Additional disturbances seem to exist in their sense of body ownership. However, the factors underlying this disturbance in body ownership remain elusive. Knowledge of these factors, and increased understanding of how body ownership is related to other abnormalities seen in schizophrenia, could ultimately advance development of new treatments. Research on body ownership in schizophrenia has mainly been investigated with the (...) rubber hand illusion (RHI). Schizophrenia patients show higher susceptibility to the RHI, which may be explained by a stronger reliance on multisensory information over weaker stored body representations. This review shows that a coherent sense of body ownership arises from the integration of both bottom-up sensory processes and higher order, top-down bodily- and perceptual representations. Multisensory integration, temporal binding, anticipation, intention and efferent signals all partly modulate the complex experience of body ownership. Specifically, we propose that patients with schizophrenia have weaker stored body representations, and rely to a greater extent on external stimuli, such as visual information, due to imprecise or highly variable internal predictions on the consequences of action. Moreover, the reduced sense of agency in schizophrenia may additionally contribute to the disturbed sense of body ownership, as evidence from healthy participants suggests that agency and body ownership are interrelated. Vice versa, a reduced sense of body ownership may also contribute to a reduced sense of agency. Future studies should explicitly target the precise relation between the two in schizophrenia.

The first English translation of a classic work in vision science from 1936 by a leading figure in the Gestalt movement, covering topics that continue to be major issues in vision research today. This classic work in vision science, written by a leading figure in Germany's Gestalt movement in psychology and first published in 1936, addresses topics that remain of major interest to vision researchers today. Wolfgang Metzger's main argument, drawn from Gestalt theory, is that the objects we perceive in (...) visual experience are not the objects themselves but perceptual effigies of those objects constructed by our brain according to natural rules. Gestalt concepts are currently being increasingly integrated into mainstream neuroscience by researchers proposing network processing beyond the classical receptive field. Metzger's discussion of such topics as ambiguous figures, hidden forms, camouflage, shadows and depth, and three-dimensional representations in paintings will interest anyone working in the field of vision and perception, including psychologists, biologists, neurophysiologists, and researchers in computational vision—and artists, designers, and philosophers. Each chapter is accompanied by compelling visual demonstrations of the phenomena described; the book includes 194 illustrations, drawn from visual science, art, and everyday experience, that invite readers to verify Metzger's observations for themselves. Today's researchers may find themselves pondering the intriguing question of what effect Metzger's theories might have had on vision research if Laws of Seeing and its treasure trove of perceptual observations had been available to the English-speaking world at the time of its writing.

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 41, no. 3. © 2015 by Feminist Studies, Inc. 623 Jaye Cee Whitehead, Kath Bassett, Leia Franchini, and Michael Iacolucci “The Proof Is in the Pudding”: How Mental Health Practitioners View the Power of “Sex Hormones” in the Process of Transition In the United States today, popular discourse touts the power of “sex hormones” and hormone receptors in the brain to chemically produce gender expressions (manifested (...) in physical sex traits, behaviors, and attitudes) and identities (a sense of self as feminine or masculine). These accounts range from common assumptions that Western ideals of femininity (such as empathy understanding, cooperative orientation, nurturing behavior) and masculinity (rational/spatial understanding, competitive orientation, violent behavior) are produced by corresponding sex hormones, to studies that reduce complex gender identities and macrosocial economic phenomena to presocial, binary, hormonal processes.1 For sociologists, accounts that reduce complex identities to internal hormonal reactions are problematic for two primary reasons: first, they are inaccurate because they fail to examine how hormonal reactions are embedded in a complex cultural process of meaning and interpretation; second, they operate as bioreductive ideologies that obscure the social power inherent to the process of gender identity construction. In what follows, we extend both of these insights by examining mental health 1. For an example of a hybrid popular-scientific account of the power of sex hormones to destabilize economic structures, see Jon Coates and Joe Herbert, “Endogenous Steroids and Financial Risk Taking on a London Trading Floor,” Proceedings of the National Academy of Sciences 105, no. 16 (April 2008): 6167–72. 624 Whitehead, Bassett, Franchini, and Iacolucci practitioners’ divergent interpretations of the power of sex hormones in the process of gender transition.2 In doing so, we examine the cultural power of sex hormones in crafting gender identities without reproducing reductionist interpretations of trans embodiment. Perhaps what is most perplexing about the way we speak of sex hormones is that we know it is inaccurate to describe these hormones as sexed; scientists have acknowledged since the 1930s that they are neither sex specific in their function, nor in terms of their location in male or female bodies.3 In her extensive historicization of sex hormones, Anne Fausto-Sterling concludes that it is more accurate to call androgen- and estrogen-based hormones, “steroid hormones” as they have functions that are not confined to corresponding sexed bodies. In fact she urges scientists to “break out of the sex hormone straightjacket” and to look at steroids as just one of a number of components that are important to the creation of sex and gender, including environment and experience.4 Scholars also point to an inextricable link between the chemical operation of hormones and the social process of constructing meaning, both at the level of social interaction and macrocultural constructions of sex categories and gender ideologies.5 While brain organization/activation theory attributes sex and gender differences to hormonal interactions within the developing brain, Fausto-Sterling questions the distinction between activation and organization by pointing out how “the brain can respond to hormonal stimuli with anatomical changes…hormonal systems, after all, respond exquisitely to experience, be it in the form of nutrition, stress, or sexual activity (to name but a few possibilities ).”6 Drawing from Elizabeth Grosz, Fausto-Sterling argues that the power of hormones is best understood according to the model of the 2. “Gender transition” is a controversial phrase, as it implies that transgendered individuals who receive hormone therapy are changing identities. We are only using it for lack of clear alternative phrasing, not because we believe body modifications change gender identities. 3.

Representations are not only used in our folk-psychological explanations of behaviour, but are also fruitfully postulated, for example, in cognitive science. The mainstream view in cognitive science maintains that our mind is a representational system. This popular view requires an understanding of the nature of the entities they are postulating. Teleosemantic theories face this challenge, unpacking the normativity in the relation of representation by appealing to the teleological function of the representing state. It has been argued that, if intentionality (...) is to be explained in teleological terms, then the function of a state cannot depend on its phylogenetical history, given the metaphysical possibility of a duplicate of an intentional being that lacks an evolutionary history. In this paper, I present a method to produce, according to our current knowledge in genetic engineering, human-like individuals who are not the product of natural selection in the required sense. This variation will be used to shed light on the main replies that have been offered in the literature to the Swampman thought experiment. I argue that these replies are not satisfactory: representations should better not depend on natural selection. I conclude that a non-etiological notion of function is to be preferred for characterizing the relation of representation. (shrink)

Mental time travel is defined as projecting the self into the past and the future. Despite growing evidence of the similarities of remembering past and imagining future events, dominant theories conceive of these as distinct capacities. I propose that memory and imagination are fundamentally the same process – constructive episodic simulation – and demonstrate that the ‘simulation system’ meets the three criteria of a neurocognitive system. Irrespective of whether one is remembering or imagining, the simulation system: acts on the (...) same information, drawing on elements of experience ranging from fine-grained perceptual details to coarser-grained conceptual information and schemas about the world; is governed by the same rules of operation, including associative processes that facilitate construction of a schematic scaffold, the event representation itself, and the dynamic interplay between the two ; and is subserved by the same brain system. I also propose that by forming associations between schemas, the simulation system constructs multi-dimensional cognitive spaces, within which any given simulation is mapped by the hippocampus. Finally, I suggest that simulation is a general capacity that underpins other domains of cognition, such as the perception of ongoing experience. This proposal has some important implications for the construct of ‘MTT’, suggesting that ‘time’ and ‘travel’ may not be defining, or even essential, features. Rather, it is the ‘mental’ rendering of experience that is the most fundamental function of this domain-general simulation system enabling humans to re-experience the past, pre-experience the future, and also comprehend the complexities of the present.

The main objective of this work was to produce a scientifically reasonable definition of God. The rationale was to generate a definition for filling a small part of the spiritual vacuum of the 21st century and thus initiate a new understanding of the Intelligence that permeates the cosmos with mystery, love, order, direction and morals. This resulted in the following definition: “God may be a-humanly incomprehensible-eternal cosmic existence, intimately related to the endlessness of space, to the nature of the deepest (...) common substance of matter and energy, to this common substance’s unceasing motion responsible for time, and to the basic laws of their allness, letting love transform this allness to an ordered Multiverse with a Soul: the—scientifically approachable—Soul of Multiverse inspired to guard these laws and equip their order with direction and morals while imbuing the cosmos with the potential of lives evolving, at the right spatial and temporal distances, to embrace the sense of the divine, thus justifying the existence of God.” The likely neural circuitry for sensing God in the human brain was identified as a network for spiritual data flow across the conscious and subconscious layers of the association cortical cognitive system exchanging data with the prefrontal cortical Self-Ken and modulated by inputs from the emotional and motivational systems of the brain. To study this mental process, the design of a God-Experience Monitor was also developed: a comfortably wearable combination of EEG and audiovisual-recorders tailored to at least partially capture the individual experiences of God anytime and at the very “genius loci” of such experiences.

One kind of substantial critique which has been raised by several philosophers against the so called higher order perception theory , advocated for mainly by William Lycan, concerns the combination of two important claims: that qualia are wide contents of perceptual experiences, and that the subject becomes aware of what the world is like by perceiving her own experiences of the world. In what sense could we possibly watch our own mental states if they are representations whose content (...) and qualitative character is determined by factors that are external to the mind? And, furthermore, how can we become aware of what the world is like by means of this process? Fred Dretske says that all we could become aware of by this alleged activity are activities of the nervous system. But being aware of what e.g., a certain colour is like to us, does not seem to be the same as being aware of what a particular nervous activation pattern is like to us. Barry Maund points out that it is not ruled out that the representational vehicle and the representational object share some properties, nor that it is in virtue of having certain properties that a mental state has the content it does. If it were the case that the properties of the representational states showed some iconic resemblance relation to that which they represent, there could perhaps be some point in watching them. But again, we have little reason for thinking that this is the case. It seems improbable that an experience of red would be red, i.e., that the representational vehicle would have these properties. The important issue is: what features could the representational vehicle possibly have that would make it suitable as an object for inner sense and, in turn, would enable us to become aware of what it is like for us to perceive external objects by “looking” at the representation of these objects? I will explore these questions in this paper. (shrink)

Today's researchers may find themselves pondering the intriguing question of what effect Metzger's theories might have had on vision research if Laws of Seeing and its treasure trove of perceptual observations had been available to the English-speaking world at the time of its writing.

ABSTRACT:Psychedelic substances have great promise for the treatment of many conditions, and they are the subject of intensive research. As with other medical treatments, both research and clinical use of psychedelics depend on our ability to ensure informed consent by patients and research participants. However, some have argued that informed consent for psychedelic use may be impossible, because psychedelic experiences can be transformative in the sense articulated by L. A. Paul (2014). For Paul, transformative experiences involve either the acquisition of (...) knowledge that cannot be obtained in any other way or changes in the self. Either of these characteristics may appear to undermine informed consent. This article argues, however, that there is limited evidence that psychedelic experiences are transformative in Paul's sense, and that they may not differ in their transformative features from other common medical experiences for which informed consent is clearly possible. Further, even if psychedelic experiences can be transformative, informed consent is still possible. Because psychedelic experiences are importantly different in several respects from other medical experiences, this article closes with recommendations for how these differences should be reflected in informed consent processes.

In lieu of an abstract, here is a brief excerpt of the content:The Concept of Experience in Locke and Hume JOHN W. YOLTON THE EMPIRICISTPROGRAM has been designed to show that all conscious experience "comes from" unconscious encounters with the environment, and that all intellectual contents (concepts, ideas) derive from some conscious experiential component. Some empiricists, but not all, have also argued that experience reports about the world. A strict empiricism would have to reject this latter claim, as Hume did, (...) although even to consider the possibility of knowledge being related to an external world is to operate on a reflective level, to seek to make sense of experience. The distinction between an account of the nature of experience--its structure, relations, and contents-and explanations of experience--its causal antecedents, its reference--is an important one. The phrase "the concept of experience" refers to the use made of some account of experience. The concept of experience need not be restricted to the experiential contents. Thus, Locke sought to show how experience is of the world, Hume tried to show how experience restricts our valid conceptual contents to certain sorts of ideas, eliminating others. Any account of experience will already be a conceptualization of experience: it must be made from the reflective level. But the account need be no more than a careful record of how the organism comes to the conscious level. Of course, such an account cannot be a straightforward description, since we cannot directly observe all of the processes operating in the production of awareness. The psychology of awareness is forced to extrapolate and conjecture. Nevertheless, we can still distinguish the psychological or descriptive account of experience from the metaphysical use made of that account. It is my purpose here to explore the accounts given and the uses made of experience by two representative empiricists, that is, by philosophers whom we look upon as advancing the empiricist metaphysic of experience. Locke's Derivation o[ Ideas From Experience Locke claimed that all mental contents come from two sources, sensory experience of the world and introspective awareness of our mental processes. The program of Book II of his Essay was to exemplify, by reference to a [53] 54 HISTORY OF PHILOSOPHY number of different ideas and concepts, this derivation of our mental contents. The counter claim for Locke was innatism, the view held by many of his contemporaries and refuted in the first book of his Essay. In order to appreciate what Locke's alternative to innatism was, we must try to discover what the program of derivation of ideas amounts to in his epistemology and what precisely he understood by the term "experience." We must first note that he offers the program of derivation in conjunction with a complex theory of mental operations. H. H. Price has remarked that it is "historically false that the empiricist thought the human mind passive. It would be more just to criticize them for making it more active than it can possibly be.''1 Mental processes play a most active and decisive role in the genesis of all ideas in Locke's account. In the case of simple ideas of sense even, the mind must be attentive to what the senses report, else that report will go unrecorded, or be recorded only at the neural level (II, I, #6, #8, and II, IX, #3). Locke frequently draws the distinction between mental contents or processes and physical processes. In the "Epistle to the Reader," where he defines "idea," he is careful to distinguish idea from the sound we "use as a sign of it." In I, I, #2 he draws a distinction between the "physical consideration of the mind" and the non-physical consideration, although he does not have a name for the latter. He also speaks there of "sensations by our organs" and "ideas in our understanding." Locke disclaimed any intention of going into the physical account of sensation. He simply accepted the current corpuscular theory. But although he is not always as precise as we would be about the physical and physiological levels of encounter, in distinction from the mental levels, he does hold to this division. II, I, #3, for instance, speaks of the senses conveying "into the mind" several "distinct perceptions... (shrink)

Inspired by Kant, Merleau-Ponty and Sellars, I illustrate and identify certain kinds of unity which are typical (if not universal) features of our conscious experience, and argue that Kant was right to claim that such unities are produced by unconscious processes of synthesis: A perceptual experience of succession is not reducible to a succession of perceptual experiences. The experience of perceiving one object as having several features is not reducible to a conjunction of perceptual experiences of those features. A cross-modal (...) perceptual experience is not reducible to a conjunction of single-modality perceptual experiences. Incoming perceptual information is synthesized into a single scene-a representation of the world as perceived from a spatio-temporal point of view. Any two of the simultaneous features of the experience of a subject S can be thought of together by S. Many of the experiences of a subject S can be thought of by S at a later time as part of his or her history of experience. These can be summarized in the general principle: An experience of a complex is not a complex of experiences. This is consistent with Sellars’ principle that: A sense-impression of a complex is a complex of impressions because the latter applies at the sub-personal, unconceptualized level, and the former at the conscious level of conceptualized experiences.

Process logic described by A. V. Smirnov is based on materials from the arab-muslim cul­ture as a whole. Process logic is contrasted with the substance logic which forms the foundation of European culture as a whole. It has been proven theoretically that any situation could be interpreted using any logic of sense. The article provides an empirical illustration of the use of the process logic in a consultation of a preschool educational in­stitution psychologist on problems connected with a mental (...) disorder of one of the pupils of the institution. On the basis of this single example it is demonstrated how process logic allows the shift of the focus of attention retaining the rational basis of the actions. Situa­tions relating to the health are difficult to describe using substantial logic as the course of the disease depends on the actions of the patient and on the actions of people in his/her immediate surroundings. This limits the usability of the law of identity which is funda­mental to substantial logic. The disease is “not that very same” disease – it is changing as the result of the actions. This creates a persistent uncertainty which is of remarkable im­portance in pediatric healthcare, where the actions of the parents are complicating the sit­uation much more significantly compared to the adult healthcare. In contrast to this, process logic allows us to observe the course of the ailment as such, as being a process, which eliminates the uncertainty. The process determines the actions regarding the ail­ment as well as their evaluation. If an action is changing the course of the ailment to the better we consider it successful. In the case described, the logic of understanding the situation used by the consultant has changed the client’s logic of understanding the situation. The person stopped seeing the problem as something rigid and insurmount­able. The change of the logic didn’t require any special training of the client. It follows that the shift of understanding from the substance logic to the process logic can help to solve practical pediatric problems. (shrink)

In 2005, an essay was published in Nature asserting that the universe is mental and that we must abandon our tendency to conceptualize observations as things. Since then, experiments have confirmed that — as predicted by quantum mechanics — reality is contextual, which contradicts at least intuitive formulations of realism and corroborates the hypothesis of a mental universe. Yet, to give this hypothesis a coherent rendering, one must explain how a mental universe can — at least in (...) principle — accommodate (a) our experience of ourselves as distinct individual minds sharing a world beyond the control of our volition; and (b) the empirical fact that this world is contextual despite being seemingly shared. By combining a modern formulation of the ontology of idealism with the relational interpretation of quantum mechanics, the present paper attempts to provide a viable explanatory framework for both points. In the process of doing so, the paper also addresses key philosophical qualms of the relational interpretation. (shrink)

Purpose. Aging is intricate process of self-transformation in view of involution of body, loss of sexual attractiveness, but at the same time, old age is a time for reconsideration of self-existence in time and in the world within coherence of life sense targets and their realization. Unique individual experience of growing old implemented in Ukrainian literature can complete the data received by gerontology. Moreover gender approach in literary gerontology highlights masculine / feminine phenotypical features of internal reverberating of aging. Theoretical (...) basis. To inquire into existential and psychological problems of aging exemplified in the twentieth-century Ukrainian Lyrics it is seems to be the most effective to employ philosophical and psychological approaches in gerontology, as well as feministic studies on elder female body discrimination, in particular in literature. Originality. This research paves the way to the development of gender and literary dimensions in Ukrainian gerontology and anthropology in general. Some of the existential and psychological problems of aging are revealed on the material of 20th-century Ukrainian poetry. The individual lyric experience of aging in different gender moods is anchored mostly in psychic, mental, sense-life strategies. Conclusions. Among the feminine strategies of aging self-reception there are observation of own elder body with anxiety and fear, its "invisibility", deepened feelings of loneliness, self-estrangement, but also finding the sense of life and soul harmony in own family, offspring. Masculine self-reception of aging deals with ideal spiritual model of Wise old man – more abstract than personal; masculine anxiety is caused by physical bodily declining, not attractiveness, but strength and power loosing.

Personal recovery entails the idea of learning to live a good life in the face of mental illness. It takes place in a continuous dynamic between change and acceptance and involves the existential dimension in the broadest sense. With cognitive self-regulation and empowerment as central elements, however, current models of recovery mostly have an individual focus instead of a relational one. Furthermore, there seems to be an emphasis on the component of change. Little attention is payed to the role (...) and integration of dealing with loss in personal recovery. In this paper, the role of loss in mental illness will be elaborated from an existential perspective. This will be done by relating existential changes to possibly disruptive experiences of loss in wider experience. With the help of several perspectives on dealing with loss it will be argued this can be integrated in processes of recovery. Then, it will be elaborated how reexperiencing a state of being surrounded, or being included, being held is a necessary part of recovery. The result consists of a refinement of the view on personal recovery. The aim of this paper is therefore twofold: (1) to arrive at a better understanding of what existential loss and loss in wider experience in the context of psychopathology entails, and (2) to further develop perspectives on recovery in mental health care.

This chapter analyzes aspects of the relationship between consciousness and intentionality. It focuses on the phenomenal character and the intentional content of perceptual states, canvassing various possible relations among them. It argues that there is a good case for a sort of representationalism, although this may not take the form that its advocates often suggest. By mapping out some of the landscape, the chapter tries to open up territory for different and promising forms of representationalism to be explored in the (...) future. In particular, it argues for a nonreductive, narrow, and Fregean variety of representationalism, which contrasts strongly with more widely explored varieties. It concludes with some words about the fundamental relationship between consciousness and intentionality. (shrink)

This Article is a contribution to the torture debate. It argues that the abusive interrogation tactics used by the United States in what was then called the “global war on terrorism” are, unequivocally, torture under U.S. law. To some readers, this might sound like déjà vu all over again. Hasn’t this issue been picked over for nearly fifteen years? It has, but we think the legal analysis we offer has been mostly overlooked. We argue that the basic character of the (...) CIA’s interrogation of so-called “high-value detainees” has been misunderstood: both lawyers and commentators have placed far too much emphasis on the dozen or so “enhanced interrogation techniques” (EITs) short-listed in government “torture memos,” and far too little emphasis on other forms of physical violence, psychological stressors, environmental manipulations, and abusive conditions of confinement that are crucial to the question of whether the detainees were tortured. Furthermore, we dispute one of the standard narratives about the origins of the program: that it was the brainchild of civilian contractor psychologists because— in the CIA’s words—“[n]on-standard interrogation methodologies were not an area of expertise of CIA officers or of the US Government generally.” This narrative ignores the CIA’s role in devising these methods, in spite of the decades of prior CIA research and doctrine about forcing interrogation subjects into a state of extreme psychological debilitation, and about how to do so—by making them physically weak, intensely fearful and anxious, and helplessly dependent. By neglecting this history and focusing on the contractors and the EITs they devised, this narrative contributes to the misunderstanding that the torture debate is about EITs and nothing else. In effect, a “torture debate” about EITs and the torture memos neglects the purloined letter in front of our eyes: the abusive conditions the CIA inflicted on prisoners even when they were not subject to EITs, including abuses that the torture memos never bothered to discuss. Unpacking what this debate is really about turns out to be crucial to understanding that such interrogation methods are torture under existing U.S. law. The U.S. Torture Act includes a clause in its definition of mental torture that was intended to ban exactly the kind of interrogation methods the CIA had researched, out of concern that our Cold War adversaries were using them: mind-altering procedures “calculated to disrupt profoundly the senses or the personality.” That is precisely the “non-standard interrogation methodology” the CIA employed after 9/11.

In sensorimotor integration, representation involves an anticipatory model of the action to be performed. This model integrates efferent signals (motor commands), its reafferent consequences (sensory consequences of an organism’s own motor action), and other afferences (sensory signals) originated by stimuli independent of the action performed. Representation, a form of internal modeling, is invoked to explain the fact that behavior oriented to the achievement of future goals is relatively independent from the immediate environment. Internal modeling explains how a cognitive system achieves (...) its goals despite variations in the environment with insufficient and noisy sensory–perceptual data. In a self that acts intentionally on the environment, knowledge is dependent upon the necessity to guide actions directed toward an aim. The self-inner model, a representation of internal and external environments (including reafferent and afferent messages) and also of the behavior plans and desirable future states (aims) and efferent intentions (motor planning and motor command messages), is intrinsically linked to a thinking capacity, which is supposed to emerge from the binding of multiple influences. Thinking emerges when higher behavior strategies are considered possible and capable of leading to aims or the fulfillment of intentions. In this model, symbolization processes are projective and anticipatory and, in this way, beyond present referents. Symbolization occurs linked to action planning, command, and regulation in mental simulation. Meaning is related to an inner sense of a self that acts over the environment. (shrink)

Subjectivity theories of consciousness take self-reference, somehow construed, as essential to having conscious experience. These theories differ with respect to how many levels they posit and to whether self-reference is conscious or not. But all treat self-referencing as a process that transpires at the personal level, rather than at the subpersonal level, the level of mechanism. -/- Working with conceptual resources afforded by pre-existing theories of consciousness that take self-reference to be essential, several attempts have been made to explain seemingly (...) anomalous cases, especially instances of alien experience. These experiences are distinctive precisely because self-referencing is explicitly denied by the only person able to report them: those who experience them deny that certain actions, mental states, or body parts belong to self. The relevant actions, mental states, or body parts are sometimes attributed to someone or something other than self, and sometimes they are just described as not belonging to self. But all are referred away from self. -/- The cases under discussion here include somatoparaphrenia, schizophrenia, depersonalization, anarchic hand syndrome, and utilization behavior; the theories employed, Higher-Order Thought, Wide Intrinsicality, and Self-Representational. Below I argue that each of these attempts at explaining or explaining away the anomalies fails. Along the way, since each of these theories seeks at least compatibility with science, I sketch experimental approaches that could be used to adduce support for my position, or indeed for the positions of theorists with whom I disagree. -/- In a concluding section I first identify two presuppositions shared by all of the theorists considered here, and argue that both are either erroneous or misleading. Second, I call attention to divergent paths adopted when attempting to explain alienation experiences: some theorists choose to add a mental ingredient, while others prefer to subtract one. I argue that alienation from experience, action, or body parts could result from either addition or subtraction, and that the two can be incorporated within a comprehensive explanatory framework. Finally, I suggest that this comprehensive framework would require self-referencing of a sort, but self-referencing that occurs solely on the level of mechanism, or the subpersonal level. In adumbrating some features of this “subpersonal self,” I suggest that there might be one respect in which it is prior to conscious experience. (shrink)

During the last couple of decades, so called representationalist theories of mind have gained increased popularity. These theories describe mental states in terms of representations of external objects and states of affairs. It is also often held that the content of a subject’s thoughts and perceptions is determined by facts outside her mind, such as social relations between her and other people and causal relations between her and external objects. Some representationalists even argue that the phenomenal character of (...) perceptual experiences is determined by external factors in the sense that the truth conditions of statements like: “it looks blue” involve such facts. This entails that so called “phenomenal properties” such as colours are not properties of my experiences or even determined by such properties. This thesis has been labelled “phenomenal externalism” by e.g., Fred Dretske1 and William Lycan2. Introspection has traditionally been described as a subject’s immediate awareness of her own experiences. It has been assumed that the subject has a special and privileged access to her experiences which means that she cannot be mistaken either about the content of her beliefs and experiences or about what they feel like to her. A long lived theory about introspection is that the introspective process is similar to perception, only the objects of the introspective process are “inner” instead of “outer”. This model seems to entail that experiences also share relevant similarities with external objects, such as having intrinsic properties, properties the subject is aware of when observing the objects in question.

Sensations can occur in the absence of perception and yet be experienced ‘as if’ seen, heard, tasted, or otherwise perceived. Two concepts used to investigate types of these sensory-like mental phenomena (SLMP) are mental imagery and hallucinations. Mental imagery is used as a concept for investigating those SLMP that merely resemble perception in some way. Meanwhile, the concept of hallucinations is used to investigate those SLMP that are, in some sense, compellingly like perception. This may be a (...) difference of degree. Attempts to reliably differentiate between instances of each type of SLMP remain unresolved. Despite this, the concepts of mental imagery and hallucinations are each routinely used independently of the other. These uses are especially interesting in those published accounts of experiments where equivalent findings about the neuroanatomical correlates of SLMP are reported in support of diverging knowledge-claims about the role of SLMP in neurocognitive processes. This practice presents a puzzle. To examine one aspect of this puzzle, I compare the uses of these two scientific concepts in three ways: examining their roles in differentiating between types of SLMP; exploring how their respective historical developments intersect; and analysing their contributions in neuroimaging experiments. In presenting this series of comparative analyses, I will draw on three themes from historical, philosophical, and social studies of scientific practices: interest in material contributions to knowledge; accounts of how concepts are used in experiments; and explorations of the historical conditions within which current practices emerge. Building on this literature, my comparative analyses supports five related claims. My first claim is that the concepts of mental imagery and hallucinations are each used as independent tools in neuroimaging experiments. My second claim is that, as experimental tools, the concepts of mental imagery and hallucinations are each used for investigating discrete epistemic goals. My third claim is that there are implicit interdependent associations that structure the uses of these two concepts as tools for independently investigating these discrete epistemic goals in neuroimaging experiments. This third claim rests on my analyses of both past and present uses of each concept. Firstly, as seen in their intersecting histories, there are disciplined performances of using the concepts of mental imagery and hallucinations that carry-along shared associations about the mediating role of SLMP in thought. Secondly, these interdependent ‘mediator-view’ associations continue to structure the independent uses of each concept as a tool for investigating SLMP in pursuit of specific goals. Taking this further, my fourth claim is that recognising the structured uses of the concepts of mental imagery and hallucinations can help to account for how equivalent SLMP-neuro-correlates are generated in support of diverging knowledge-claims. Finally, my fifth claim is that the structured uses of these concepts as tools can contribute to experiments in ways analogous to, yet not equivalent with, the active contributions of material instruments. Bringing these claims together, I argue that the concepts of mental imagery and hallucinations operate as structured tools that can actively contribute to the knowledge generated by neuroimaging experiments. In presenting this argument I seek to demonstrate that examining the structured uses of concepts as tools can complement existing approaches to studying how the heterogeneous dynamics of experimental practices can come to contribute to scientific knowledge in unintended ways.

It is generally accepted that there is something special about reasoning by using mental images. The question of how it is special, however, has never been satisfactorily spelled out, despite more than thirty years of research in the post-behaviorist tradition. This article considers some of the general motivation for the assumption that entertaining mental images involves inspecting a picture-like object. It sets out a distinction between phenomena attributable to the nature of mind to what is called the cognitive (...) architecture, and ones that are attributable to tacit knowledge used to simulate what would happen in a visual situation. With this distinction in mind, the paper then considers in detail the widely held assumption that in some important sense images are spatially displayed or are depictive, and that examining images uses the same mechanisms that are deployed in visual perception. I argue that the assumption of the spatial or depictive nature of images is only explanatory if taken literally, as a claim about how images are physically instantiated in the brain, and that the literal view fails for a number of empirical reasons – for example, because of the cognitive penetrability of the phenomena cited in its favor. Similarly, while it is arguably the case that imagery and vision involve some of the same mechanisms, this tells us very little about the nature of mental imagery and does not support claims about the pictorial nature of mental images. Finally, I consider whether recent neuroscience evidence clarifies the debate over the nature of mental images. I claim that when such questions as whether images are depictive or spatial are formulated more clearly, the evidence does not provide support for the picture-theory over a symbol-structure theory of mental imagery. Even if all the empirical claims were true, they do not warrant the conclusion that many people have drawn from them: that mental images are depictive or are displayed in some (possibly cortical) space. Such a conclusion is incompatible with what is known about how images function in thought. We are then left with the provisional counterintuitive conclusion that the available evidence does not support rejection of what I call the “null hypothesis”; namely, that reasoning with mental images involves the same form of representation and the same processes as that of reasoning in general, except that the content or subject matter of thoughts experienced as images includes information about how things would look.

In this dissertation, I provide the logical foundation for a solution to the mind-body problem, a solution which is directly based upon Wilfrid Sellars' analogical theory of thought and sensation. Chapters I-IV are devoted to an interpretation, analysis, and constructive criticism of Sellars' notions of the inner thought episode and the sensing state. My analysis is offered in support of three general contentions: I argue that the postulation of inner thought episodes and sensing states is necessary for adequate explanations of (...) agent behavior; I hope to show how the analogical theory of inner thought episodes and sensing states actually generates a legitimate problem concerning the relationship between the mental and the physical; and I demonstrate the importance of the notion of analogy in philosophical theory construction. I suggest that the role of analogy provides the key for the solution to the mind-body problem. ;Chapter One is essentially introductory in nature. I offer an interpretation and reconstruction of Sellars' illustrative story entitled "The Jonesean Myth" . The "Myth" provides a suitable representation of Sellars' overall philosophy of mind. But perhaps more importantly, the "Myth" is a paradigm example of what I shall call the analogical method of inquiry, a method employed for the introduction of the notions of inner thought episodes and sensing states. In brief, I want to show how the "Myth" provides the logical basis for a theory adequate for explanations of the mental activity of agents. ;Chapters II and III are closely related. In Chapter II, I present a theory of linguistic representation which will serve as the analogical base for the introduction and characterization of the inner thought episode. In Chapter III, I develop the notion of the inner thought episode , and I examine its nature and status as a theoretical construct. Chapters II and III are thus related by the Sellarsian thesis that the concept of mental representation is to be understood in terms which apply, primarily, to characterizations of the features of the linguistic framework presented in Chapter II. ;In Chapter IV, I argue, again following Sellars' lead, that the explication of the notion of the perceptual thought episode requires the introduction of a second distinct sort of inner episode, namely, that of the sense experience or sensing state. The argument offered in Chapter IV is designed to show that sensing states are theoretical constructs, the reference to which is essential for explanations concerning the occurrence and nature of perceptual representations. Sensing states are introduced and characterized by an analogical extension of families of predicates which are suitable for the identification and description of ordinary physical objects . ;In Chapter V, I propose a solution to the mind-body problem, as the latter is generated by the analysis given to the thought episode and the sensing state . In general terms, I argue that any purported solution to the mind-body problem must provide an explanatory basis for agent behavior, and it is for this reason that I reject "reductionistic" theories of mind of the kind represented by logical behaviorism, type-identity physicalism, and Turing Machine functionalism. My solution, instead, involves a commitment to what I shall call token physicalism, a thesis which is contingent upon the development of a theory of neurophysiology which is rich enough to capture, in an analogical sense, both the intentional features of the thought episode, and the occurrent-like qualities which are exemplified by the sensing state.

Consciousness, as a higher-order cognitive capacity allowing for the explicit representation of abstract mental states, might be the incidental byproduct of design features from other adaptive systems, such as those governing expansion of the frontal lobes in primates. Although such abilities may have occurred entirely by chance, the standardized entrenchment of this representational capacity in human cognition may have posed engineering dilemmas for natural selection in that consciousness could not be easily removed without disrupting the adaptive features of (...) other design solutions. If so, then those organisms saddled with the burden of higher-order representation by the occurrence of these chance events were suddenly assaulted with a series of social problems previously unencountered by any other species in evolutionary history. Such consciousness-based problems constituted enormous selective pressure for generating ancestrally adaptive psychological programs designed to cope with them. Each of these design solutions was, by necessity, generated and progressively pruned over an extraordinarily short span of geological time. In addition, these programs ran into conflict with more ancient primate social adaptations — such as those underlying sexual coercion and violence — that did not evolve to be sensitive to the epistemic positions of others. These mosaic processes have likely resulted in selection for innumerable algorithmic properties driving human-specific behaviors which are both proximally and ultimately caused by consciousness. Consciousness by itself should be classified as maladaptive; what is adaptive are those psychological programs in place to support its incidental and problematic arrival in the human brain. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:A Culture of Engagement: Law, Religion, and Morality by Cathleen KavenyAllen CalhounA Culture of Engagement: Law, Religion, and Morality Cathleen Kaveny WASHINGTON, DC: GEORGETOWN UNIVERSITY PRESS, 2016. 320 pp. $98.95 / $32.95It is encouraging to read a book on the intersection of religion and law from an author as conversant with both fields as is Cathleen Kaveny. Reworking a number of columns that she wrote for Commonweal magazine, (...) Kaveny offers her concept of a "culture of engagement" as an alternative to America's polarizing culture wars. She builds a vision of engagement—typified by Pope Francis's emphasis on the church's need to "encounter" all human beings—that welcomes the influence that religious traditions and the broader culture and its laws can have on each other.Kaveny notes two ways in which the Roman Catholic tradition is particularly well situated to engage American culture and law. First, both American common law and the Catholic moral tradition use forms of "casuistry" to connect general rules with particular situations. Second, Catholic reluctance "to draw sharp lines between the pure and the tainted" can supply a salutary alternative to the Puritan tendency toward "prophetic indictment" (16).In part 1, Kaveny argues that law has both pedagogical and pragmatic qualities. In part 2, she describes the nation's struggle to balance governmental interests and religious liberty in the context of the contraception mandate in the 2010 Affordable Care Act. She faults the United States Conference of Catholic Bishops for elevating the law's pedagogical role over its pragmatic function in their attack on the mandate. She herself leans toward pragmatism; she assumes that exceptions to laws of general applicability should apply only "in the most extreme cases" (116) and that the government—not the religious claimant—should determine when exceptions apply.Kaveny also suggests that the bishops would do well to pay greater attention to the common good, as "it reflects the moral consensus of the community, which is accurately reflected in our democratic process of lawmaking" (90). Development of the grounds for this optimistic linking of a moral consensus and majority rule to the common good would have been an interesting addition to the book.Part 3 is the heart of the work, exploring ways for American society to "move beyond a culture war mentality" (120). Kaveny resists the assumption that public discourse in a society torn by culture wars is served by pitting secular and religious voices against each other. She hopes instead for persuasion based on natural law. One is left wondering, however, how persuasion based on natural law could happen in America's ideologically diverse culture. [End Page 201]Part 4 explores the effect of America's ideological pluralism on discussions among American Catholics. Kaveny describes how the church's sexual abuse scandal has fed the growing sense of disconnection between church teaching and the expectations of the Catholic laity.Part 5, a series of essays on difficult ethical controversies, hints at what interaction between the American and Catholic traditions might look like. Kaveny advocates "reframing the question" and hints at what reframing the contraception question might look like (221).Some of the book addresses specifically Catholic questions. It is valuable in that respect. Its scope extends beyond any one religious tradition, however, as it offers a picture of engagement between equals: the American legal tradition and Catholic moral teaching. Nevertheless, Kaveny makes it clear that this sort of engagement can succeed only if the American legal community understands its need to reflect changing social values and the Catholic hierarchy moves away from insisting that "error has no rights" and toward acknowledging that people do have rights even when they are in error (257).Allen CalhounPhD candidate, University of AberdeenCopyright © 2018 Society of Christian Ethics...

As there are contradictions in the digital technology: 1) a tool for professional growth and 2) a tool for imposing a prepared scenario of achieving success on the subject, ignoring the principle of environmental compliance, our study aims to substantiate and experimentally test the effectiveness of the model of realization of modern student’s mental experience. Moreover, the technology of programming as philosophizing in the BSL format is considered to be an element in the humanization of geeks culture in the (...) situation of supposed technological singularity. In accordance with the goal, we have created a regression-correlation design for the study of the influence of the predictor variable on the criterion variable. The exploratory methodology of our experimental study is determined by the content of bite sized-approbation of the author's model ‘Flipped Class’. Its conceptual idea is self-learning as creativity, which is realized in the didactics of performative action. The results of the tasks have revealed the relationships and differences in the implementation of indicators of students’ mental experience of joint e-Learning and BSL, which are visualized in correlation galaxies for future clustering. They have confirmed the leading idea of ​​our study: the disclosure of the resources inherent in human nature in the process of learning is the way for the relentless cognition of the sense of placement with a view to achieving dignity and making free choices in life.

Spatial aspects of words are associated with their canonical locations in the real world. Yet little research has tested whether spatial associations denoted in language comprehension generalize to their corresponding images. We directly tested the spatial aspects of mental imagery in picture and word processing (Experiment 1). We also tested whether spatial representations of motion words produce similar perceptual-interference effects as demonstrated by object words (Experiment 2). Findings revealed that words denoting an upward spatial location produced slower (...) responses to targets appearing at the top of the display, whereas words denoting a downward spatial location produced slower responses to targets appearing at the bottom of the display. Perceptual-interference effects did not obtain for pictures or for words lacking a spatial relation. These findings provide greater empirical support for the perceptual-symbols system theory (Barsalou, 1999, 2008). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:NEWMAN'S PSYCHOLOGICAL DISCOVERY: THE ILLATIVE SENSE (Continued) VI THE FACULTIES OF COGNITION AND APPETITION Since the Grammar of Assent gives us a phenorhenological analysis of the art of thinking and often refers to the influence of other faculties in our reasoning processes, it will be very instructive to examine what the author holds about our faculties of cognition and appetition. This will make us better acquainted with the nature (...) of the illative sense. I. THE SENSES 1. The External Senses and their Objects. We had already arrived at the conclusion that Newman rejects the mere subjectivity of our knowledge. When he writes about this matter he explicitly deals with sensation or sensuous cognition. Although he takes exception to the word "immediate perception," 1 we may nevertheless call him an adherent of direct or immediate realism according to Scholastic terminology, because he emphatically excludes the intervention of a reasoning process from sense perception and uses the term "mediate perception" only to express the instrumentality of experience. In this meaning our perception of external objects is mediate or indirect indeed.2 The fact is that as early as 1839 he wrote in his University Sermons: "Of the material we have direct knowledge through the senses"3 and in 1843: "The senses are direct, immediate, and ordinary informants, and act spontaneously without any will or effort on our part."4 On the importance of sense perception for our mental activities he writes in a series of hitherto unpublished notes, entitled Elements of Thought:6 "I grant or I assume that the soul would not think without some external stimulus; that if it were cut off from all communication from the external world, it would pass this life in a sort of torpor... But then, as soon as it is roused, it reflects upon itself, and thereby gains a number of ideas..." 1. See supra V, 14.2. Supra V, 14.3. P. 205. 4.P. 303 ; cf. Gramm., p. 260. 5.See the unpublished Philosophical Papers, note Fcbr. 24, 1859. 40 DR. ZENO, OJM. CAP.41 Apart from the passages already referred to, Newman nowhere enlarges on the doctrine about the senses. He does not speak about the distinctions between sensible objects; he does not explain the difference between sensation and perception, and uses those terms promiscuously.6 There are no statements on the subject which contradict current Scholastic notions, although sometimes his vague terminology may be an occasion for misunderstandings. For instance, some passages in connection with "images" and "impressions," when read apart from the context, would appear to imply that he identifies them with the Scholastic species a sensibili accepta. However, we shall show further on that. Newman means something quite different. He deals with these species and the so-called sensibilia per acci· dens by the way when describing our knowledge of God7 and teaching that we have evidence of the presence of individuals or substances in the phenomena which occur to our senses. We picture those things to ourselves in those phenomena. They are like pictures, he says, but at the same time "they give us no exact measure or character of the unknown things beyond them." "Therefore when we speak of our having a picture of the things which are perceived through the senses, we mean a certain representation, true as far as it goes, but not adequate." 2. The Internal Senses and their Objects. Newman nowhere gives a distinction between external and internal senses, but nevertheless he speaks about those faculties of the mind which by the Scholastics are called the internal senses. These philosophers distinguish a common sense or rather a central sense (sensus communis), which unites the impressions of the external senses into one whole, makes us conscious of the conditions of our body and notifies to us the sensations of our external as well as internal senses; — the imagination or the faculty which preserves and reproduces things perceived; — the sensuous memory, i. e., the power to retain and to reproduce sense images; — and the vis aestimativa or the instinctive faculty, which discovers without any intellectual means, what is good and what is bad for our welfare. 6.It would seem that he generally...

Contrary to some well-known views in cognitive science and the philosophy of mind, in general it is not the case that the felt character of sensory experiences is determined by the information that these experiences pick up, or represent, about the world. In this dissertation I shall focus on a particular sensory modality, namely color vision, to support this thesis. ;Recently there has arisen a strong and popular view of phenomenal consciousness according to which the two fundamental problems about the (...) mind: intentionality and phenomenal experience, can be traced back to just one: intentionality. On this view, the phenomenal aspect of experience is a special case of intentionality, or our mental states' carrying information about the external world. For instance, when we see the colors of objects, we see, in a direct and transparent way, exactly those kinds of properties that the external objects have. Not only are the colors of objects causally responsible for our experiences as of color, object colors crucially determine what is called the phenomenal character of color experience. ;In this dissertation I shall argue that this view of color experience---the view called representational externalism---cannot be correct. I shall argue that from the empirical facts about object color and color vision we need not conclude that object colors do not exist, hence color vision is a grand illusion, however, we do have to conclude from these facts that though object colors are the causes of our color experience, what it is like to see the colors is not, in any theoretically interesting sense, determined by the colors themselves. To the contrary, what it is like to see the colors is crucially determined by how our color vision systems are constructed. In this dissertation I offer two independent arguments to support this claim. (shrink)

High-level perception--”the process of making sense of complex data at an abstract, conceptual level--”is fundamental to human cognition. Through high-level perception, chaotic environmen- tal stimuli are organized into the mental representations that are used throughout cognitive pro- cessing. Much work in traditional artificial intelligence has ignored the process of high-level perception, by starting with hand-coded representations. In this paper, we argue that this dis- missal of perceptual processes leads to distorted models of human cognition. We examine some (...) existing artificial-intelligence models--”notably BACON, a model of scientific discovery, and the Structure-Mapping Engine, a model of analogical thought--”and argue that these are flawed pre- cisely because they downplay the role of high-level perception. Further, we argue that perceptu- al processes cannot be separated from other cognitive processes even in principle, and therefore that traditional artificial-intelligence models cannot be defended by supposing the existence of a --œrepresentation module--� that supplies representations ready-made. Finally, we describe a model of high-level perception and analogical thought in which perceptual processing is integrated with analogical mapping, leading to the flexible build-up of representations appropriate to a given context.

: The development of the interdisciplinary areas of cognitive, affective and action neurosciences contributes to the identification of neurobiological bases of conscious experience. The structure of consciousness was philosophically conceived a century ago as consisting of a subjective pole, the bearer of experiences, and an objective pole composed of experienced contents. In more recent formulations, Nagel refers to a “point of view”, in which qualitative experiences are anchored, while Velmans understands that phenomenal content is composed of mental representations (...) “projected” to the space external to the brains that construct them. In Freudian psychology, the conscious mind contains a tension between the Id and the Ego. How to relate this bipolar structure with the results of neuroscience? I propose the notion of projection [also used by Williford et al. ] as a bridge principle connecting the neurobiological systems of knowing, feeling and acting with the bipolar structure. The projective process is considered responsible for the generation of the sense of self and the sense of the world, composing an informational phenomenal field generated by the nervous system and experienced in the first-person perspective. After presenting the projective hypothesis, I discuss its philosophical status, relating it to the phenomenal and high-order thought approaches, and a mathematical model of projection. Eight ways of testing the status of the projective hypothesis are briefly mentioned. Resumo: O desenvolvimento de áreas interdisciplinares das neurociências, contribui para a identificação das bases neurobiológicas da experiência consciente. A estrutura intrínseca da experiência consciente foi filosoficamente concebida há um século como consistindo de um pólo subjetivo, o portador de experiências, e um pólo objetivo, composto dos conteúdos experimentados. Em formulações mais recentes, Thomas Nagel refere-se a um “ponto de vista”, no qual experiências qualitativas são ancoradas, enquanto Max Velmans entende que o conteúdo fenomenal é composto de representações mentais “projetadas” para o espaço externo ao cérebro que as constrói. Na psicologia freudiana, a mente consciente contém uma tensão entre o Id e o Ego. Como relacionar esta estrutura bipolar com os resultados da neurociência? Proponho a noção de projeção como princípio-ponte, conectando os sistemas neurobiológicos do saber, sentir e agir com a estrutura bipolar. O processo projetivo é considerado responsável pela geração do sentido do eu e do sentido do mundo, compondo um campo fenomenal informacional gerado pelo sistema nervoso e vivenciado na perspectiva da primeira pessoa. Após apresentar a hipótese projetiva, discuto seu status filosófico, relacionando-o às abordagens fenomenológicas, à teoria do pensamento de ordem superior e ao modelo matemático da projeção. Oito maneiras de testar o status da hipótese projetiva são brevemente mencionadas. (shrink)

Philosophical discussion about the reality of sensory perceptions has been hijacked by two tendencies. First, talk about perception has been largely centered on vision. Second, the realism question is traditionally approached by attaching objects or material structures to matching contents of sensory perceptions. These tendencies have resulted in an argumentative impasse between realists and anti-realists, discussing the reliability of means by which the supposed causal information transfer from object to perceiver takes place. Concerning the nature of sensory experiences and their (...) capacity to provide access to reality, this article challenges the standard categories through which most arguments in this debate have been framed to date. Drawing on the underexplored case of olfaction, I first show how the details of the perception process determine the modalities of sensory experiences. I specifically examine the role of measurement and analyze its influence on the characterization of perceptions in olfaction. My aim is to argue for an understanding of perception through a process view, rather than one pertaining to objects and properties of objects. (shrink)

Chapter 1 First Person Access to Mental States. Mind Science and Subjective Qualities -/- Abstract. The philosophy of mind as we know it today starts with Ryle. What defines and at the same time differentiates it from the previous tradition of study on mind is the persuasion that any rigorous approach to mental phenomena must conform to the criteria of scientificity applied by the natural sciences, i.e. its investigations and results must be intersubjectively and publicly controllable. In Ryle’s (...) view, philosophy of mind needs to adopt an antimentalist stance to achieve this aim. Antimentalism not only definitively rejects the idea that mind is a substance separated from the body, it also denies that mental phenomena radically differ from physical phenomena by virtue of several unique features. Most problematically, mental phenomena have a conscious character (mental states are related to specific qualitative feelings) and are accessible only to the first-person (only the subject knows directly what s/he is experiencing inside his/her mind). Ryle takes a strong stance on antimentalism going so far as to maintain that an approach to mind which aims to meet the criteria of scientificity set by the natural sciences must avoid any reference to internal, unobservable mental states. In his view (which is considered a specifically philosophical version of psychological behaviorism and also addresses questions put forward in psychological research), mental states can be redescribed in terms of behavioral dispositions. In this chapter, we address the historical roots of the antimentalist view and analyze its relation to the later tradition of research on mind. We show that, compared to the antimentalist stance, functionalism and cognitivism take a step back when they maintain that direct reference to mental states is necessary since mental states cause and therefore explain human behavior. This step backwards is often interpreted as a return to mentalism. However, this is only partially true. Indeed, we suggest that these later traditions retain one important element of Ryle’s antimentalism, i.e. the idea that mental states must be uniquely identified using external and publicly observable criteria, while excluding any reference to introspection and those qualitative dimensions of a mental state, which are accessible only to the first-person. According to the perspective we put forward, this epistemological stance has continued to influence contemporary research on mind and current philosophical and psychological theories which both tend to exclude the subjective qualities of human experience from their accounts of how the mind works. The issue we raise here is whether this is legitimate or whether subjective qualities do play a role with respect to the way our mind works. The conclusion of this chapter anticipates the argument the book makes in in favor of this latter position, starting from a particular angle, i.e. the problem of how we categorize concepts related to our internal states. -/- Chapter 2 The Misleading Aspects of the Mind/Computer Analogy. The Grounding Problem and the Thorny Issue of Propriosensitive Information -/- Abstract. After the crisis of behaviorism, cognitivism and functionalism became the predominant models in the field of psychology and of philosophy, respectively. Their success is mainly due to the new key they use for interpreting mental processes: the mind/computer analogy. On the basis of this analogy, mental operations are seen as cognitive processes based on computations, i.e. on manipulations of abstract symbols which are in turn understood as informational unities (representations). This chapter identifies two main problems with this model. The first is how these symbols can relate to and communicate with perception and thus allow us to identify and classify what we perceive through the senses. Here we limit ourselves to presenting this issue in relation to the classical symbol grounding problem originally put forward by Harnad on the basis of Searle’s Chinese room argument. An attempt to address the problem raised here will be made in chap. 3. The second point we discuss in relation to the mind/computer analogy concerns the idea of information it fosters. Indeed, following this analogy, information is something available in the external world which can be captured by the senses and transmitted to the central system without being influenced or modified by the procedures of transmission. This perspective does not take into account that – unlike computers – in living beings information is acquired by means of the body. As Ulric Neisser has already pointed out, the body is itself an informational source that provides us with additional sensory experience that influences (modifies or complements) the information extracted from the external world by the senses. To develop this line of analysis and to determine exactly what information is provided by the body and how this might influence cognition, we examine Sherrington’s and Gibson’s positions. Moving on from their views, we qualify bodily information in terms of ‘proprioception’. We use ‘proprioception’ in a broad sense to describe any kind of experience we have of our internal states (including postural information as well as sensations related to the general state of the body and its parts). Following Damasio’s and Craig’s studies, we further elaborate this position, arguing that living beings are equipped with an internal propriosensitive monitoring system which maps all the changes that constantly occur in our body and that give us perceptual (‘proprioceptive’ or propriosensitive) information about what happens inside us. Moreover, relying on Goldie’s and Ratcliffe’s view, we show that emotional information can also be considered as a form of ‘proprioception’ which contributes to determining everything we perceive. This analysis leads us to the second main thesis of this book: ‘proprioception’ is a form of internal perception and it is an essential component of the sensory information we can access and use for all cognitive purposes. -/- Chapter 3 Semantic Competence from the Inside: Conceptual Architecture and Composition -/- Abstract. Concepts are essential constituents of thought: they are the instruments we use to categorize our experience, i.e. to classify things and group them together in homogeneous sets. Here we define concepts as the internal mental information (representations) that allows us, among other things, to master words in natural language. By analyzing the way in which individuals master word meanings we explore a number of hypotheses regarding the nature of concepts. Following Diego Marconi’s research, we differentiate between two kind of abilities that underpin lexical competence – so-called ‘referential’ and ‘inferential competence’ – and we suggest that, in order to support these abilities, concepts must also include two corresponding kinds of information, i.e. inferential and referential information. We point out that the most widely used and acknowledged theories of concepts do not make this distinction, instead broadly characterizing the information used for categorization in terms of propositionally described feature lists. However, we show that while feature lists can explain inferential competence, they do not account for referential competence. To address the issue of referential competence we examine Ray Jackendoff’s hypothesis that to account for the possibility of linking perceptual and conceptual information we need to assume the existence of a (visual) representation that encodes the geometric and topological properties of objects and bridges the gap between the percept and the concept. Furthermore, we analyze the extension of this work by Jesse Prinz who introduced the notion of a proxytype, a perceptual representation of a class of objects that incorporates structural and parametric information related to their appearance. However, as we point out, proxytypes can only explain the relationship between perception and concepts with respect to instances that can be perceived through the senses and that belong to the same class by virtue of their physical similarity. We suggest that this notion be extended to include larger conceptual classes. To accomplish this, we further develop Mark Johnson, George Lakoff and Jean Mandler’s idea of a schematic image and argue that conceptual representations include a perceptual schema. Perceptual schemata are non-linguistic, structured experiential gestalts (patterns or maps) that make use of information taken from all sensory modalities, including body perception. They accomplish a quasi-conceptual function: they allow us to recognize and to classify different instances. In this work, we hypothesize that perceptual schemata are an essential component of concepts, but not identical to them. Instead, we suggest that concepts include both perceptual and propositional information with perceptual schemata providing the ‘perceptual core concept’ that grounds related propositional information. -/- Chapter 4 In the Beginning There Were Categories. The Bodily Origin of Prelinguistic Categorical Organization: The Example of Folkbiological Taxonomies -/- Abstract. Studies of categorization in psychology and the cognitive sciences have made use of the notions of ‘category’ and ‘concept’ without precisely defining what is meant by either; in fact, often these terms have been used as synonyms, making it difficult to address specific issues related to conceptual development. This chapter begins by discussing the definitions of, as well as the distinctions between, ‘categories’ and ‘concepts’ in the classical philosophical tradition (Aristotle, Kant and Husserl). We introduce our view of categories with reference to Husserl. Categorization is defined as the way in which our experience is originally (pre-linguistically) organized in a passive and fully unconscious manner on the basis of universal structuring principles. Conceptualization is explained as a later process in which the earlier categorical macro-classes are further subdivided into more specific and detailed sets; this later process also relies on linguistic learning and exposure to culture. On the basis of Ray Jackendoff, Jean Mandler, George Lakoff and Mark Johnson’s work, we hypothesize that categorization is a two-step process that begins with the formation of homogeneous sets of entities partitioned into regions that describe the ontological boundaries of the objects that humans perceive (categories) and continues at a later stage with the development of more specific classifications (concepts). In this chapter, we mainly address three related issues: Why should we assume that there is categorical organization which precedes the development of a conceptual system? How do categories and concepts relate to each other? Shall we hypothesize that categories are innate or that they are formed before concepts on the basis of information and organizational structure available at a very early developmental stage? We show that categorical partitions are necessary for categorization and, following Mandler, that the general categories we form at an early age do not match our adult superordinate concepts. As for the third issue, we argue that there might be no need to assume that categories are innately present in the human mind, since their formation can be explained – at least in certain cases – by basic mechanisms that work on body (propriosensitive) information. This hypothesis will not be discussed in general, but in relation to a particularly relevant example of categorical partition, i.e. the folk-biological dichotomy between ANIMATE/INANIMATE. This is compared with other dichotomies that derive from it, but are not directly categorical such as LIVING/NON-LIVING and BIOLOGICAL/NON-BIOLOGICAL. -/- Chapter 5 Internal States: From Headache to Anger. Conceptualization and Semantic Mastery -/- Abstract. Here we ask if we can also apply the distinction between referential and inferential competence we introduced in Chapter 3 to words that do not refer to things that are perceived using the external senses, especially to words/concepts that denote bodily experiences (such as pain, thirst, hunger, etc.) or emotions. We introduce and discuss the hypothesis that – even though such words/concepts do not refer to intersubjectively identifiable entities in the external world – they do have a kind of referent that can be accessed via direct perception, more specifically ‘proprioception’, as we have defined it in terms of all propriosensitive information we can consciously access. In the first part of the chapter, we specifically consider terms denoting bodily experiences such as ‘pain’ or ‘hunger’ and argue that their referents are identified and classified from a first-personal point of view on the basis of four main characteristics: their specific intensity, their localization in the body, their co-occurrence with other signals and above all their specific qualitative sensations. Emotions are addressed in the second part of the chapter. We suggest that there is a continuity between bodily experiences and emotions. In particular, we argue for a perceptual theory of emotions in line with that proposed by James and Lange at the end of the 19th century and developed more recently by authors such as Damasio (see also chap. 2§5, §6). The hypothesis we put forward is that the referential information that supports the categorization of emotions and therefore also our mastery of terms referring to emotions consists in the perception (i.e. the ‘proprioception’) of those bodily states and changes in bodily states which constitute our emotional experience. In the context of this discussion we examine some objections to this line of reasoning that arise from a cognitivist perspective and following authors such as Oatley, Johnson-Laird and Frijda, we distinguish between basic emotions that can be identified and classified solely on the basis on how they feel and complex emotions whose identification and classification additionally depends on cognitive factors. To describe how emotions are identified and classified on the basis of how they feel, we rely on Marcel and Lambie’s distinction between an ‘emotion state’ and an ‘emotion experience’. Both notions indicate kinds of feelings that we consciously experience. However, they describe first-order and second order emotion awareness respectively. The emotion state is the feeling we have of the bodily states and changes that occur when we are experiencing an emotion, while the emotion experience is the fully developed and integrated emotion we both experience and are, with reflection, aware of experiencing. On the basis of this differentiation, we also show that the same characteristics that aid in the identification and classification of bodily experiences (specific qualitative sensations; somatic localization; specific intensity; presence/absence of specific concomitant sensations) can also be used for the identification and classification of emotions – at least basic emotions. In the last two sections of the chapter we present some clinical evidence on the semantic competence of people who suffer from Alexithymia and Autism Spectrum Disorder which supports the conclusions of our preceding analyses. -/- Chapter 6 The ‘Proprioceptive’ Component of Abstract Concepts -/- Abstract. In this chapter, we address the issue of whether the mastery of abstract words requires only inferential knowledge and thus, if the concepts that support the mastery of abstract words include only linguistic information. We start by differentiating the notions of ‘abstract’ and ‘general’ which are often erroneously confused. We then identify a strict definition of abstract, as contrasted with ‘concrete’, that applies to words or concepts whose referent cannot be experienced by the senses. We argue that abstract words/concepts would be better described as theoretical, because they are usually conceived as structured sets of inferential knowledge expressed linguistically; that is, as small theories. Pointing out parallels with Carnap’s analysis of this issue in philosophy of science, we hypothesize that words/concepts denoting non-observable entities are not all ‘equally theoretical’, because their link to sensory experience can be stronger or weaker. We revive the distinction, inspired by Quine, between theoretical and intertheoretical concepts/words. This distinction relies on the fact that the former – unlike the latter – retains a strong, although indirect, connection with perception. In Quine’s discussion, perception is understood uniquely in terms of observability, i.e. of external sensory experience. Here we argue, however, that bodily, ‘proprioceptive’ (i.e. propriosensitive) experience can also serve to referentially ground theoretical (i.e. abstract) concepts/words. We frame this issue using the example of the theoretical concept ‘freedom’ and Lakoff’s hypothesis that this concept is developed on the basis of bodily information. We contrast this with the example of ‘democracy’ which more closely resembles an intertheoretical concept/word. Furthermore, we show that one of the classical views put forward in psycholinguistic research to explain how abstract concepts are mentally represented – i.e. Paivio’s Dual Coding Theory – points in the same direction as our analysis. The same is true of Barsalou’s work suggesting that we use internal information to understand at least some abstract words. To sustain this position, we put forward two lines of evidence: the first comes from psycholinguistic studies while the second examines deficits of semantic competence exhibited by people with Autism Spectrum Disorder. On the basis of our analysis, we put forward a classification that distinguishes between different kinds of concreteness and different degrees of abstraction: concepts/words referring to body experiences and basic emotions are described as analogous to concrete concepts/words because they are grounded in perceptual (i.e. propriosensitive) experience, while abstract concepts/words are considered more or less abstract depending on whether they are intratheoretical (and rely entirely on inferential information) or theoretical (and are partially grounded in perceptual – or more often in propriosensitive perceptual – information). In the last section of the chapter we consider two scales that have been used in psycholinguistic research to measure the degree of concreteness vs. abstractness of words and we show that – used conjointly – they can provide a measure of the internal vs. external grounding of specific words.
