Note: Paper to appear in special issue of the journal Psychology of Consciousness: Theory, Research, and Practice, on the evolution of consciousness //// Klein, Nguyen, & Zhang (in press) argued that the evolutionary transition from respondent to agent during the Cambrian Explosion would be a promising vantage point from which to gain insight into the evolution of organic sentience. They focused on how increased competition for resources -- in consequence of the proliferation of new, neurally sophisticated life-forms -- made awareness (...) of the external world (in the service of agentic acts) an adaptive priority. The explanatory scope of Klein et al (in press) was limited to consideration of the conscious apprehension of externally sourced content – i.e., content delivered from the sensory registration of objects occupying phenomenal space. But consciousness – at least for humans -- takes its objects from internal as well as external sources. In the present article we extend their analysis to the question of how internally sourced content (i.e., mental states) became the object of conscious apprehension. (shrink)

This paper shows that Husserl is not guilty of Sellars’ myth of the sensory given. I firstly show that Husserl’s account of ‘sensations’ or ‘sense data’ seems to possess some of the attributes Sellars’ myth critiques. In response I show that, just as Sellars thinks that our ‘conceptual capacities’ afford us an awareness of a logical perceptual space that has a propositional structure, Husserl thinks that ‘acts of apprehension’ structure sensations to afford us perception that is similarly propositionally structured. (...) Not only this, but there is much affinity and shared motivation between Husserl and Sellars accounts of the sensory stratum. Reflection on phenomenological considerations prevents Sellars from denying phenomenal non-conceptual content, whilst Husserlian ‘sense data’ are technical designations; dependant parts of perceptual experience grasped in abstraction, necessary for providing a reflective/philosophical account of empirical knowledge. I show that both Husserl and Sellars assert that the proper description of phenomenal content affords it the function of presenting properties of spatial objects during perception, and reiterate the well-known fact that Husserl thinks that perception is of ‘conceptually’ apprehended spatiotemporal objects.

Traditionally the modern theory of ideas has been discussed primarily in reference to its alleged introduction of a veil of mental items between the mind and the world, which leads, through the empiricists, to radical skepticism about the existence of an external world. Here I propose to emphasize an entirely different aspect of the Cartesian theory of ideas which, in my view, is more fundamental in opening the empiricist path that leads to Hume’s radical skepticism. I argue that what I (...) call the “phenomenological presentation” model of ultimate justification is rooted in a fundamental ambiguity between sensible and intellectual apprehension insinuated by Descartes’s view of “clear and distinct” ideas together with his emphasis on the priority of intuition over logical inference. Sensible apprehension relies on immediate acquaintance with items pheno-menologically and ostensively present before the mind as given particulars. The phenomenological presentation model takes its clues from sensible apprehension, although the items present before the mind might themselves be either ideas of the understanding, images of the imagination, sensory impressions, or material external objects. Intellectual apprehension, by contrast, as I illustrate with Leibniz’s model of our knowledge of concepts and truths of reason, consists in the discursive, non-ostensive grasping of the generality of abstract concepts and of formal structures . For Leibniz, all intellectual apprehension is unambiguously “logical discursive apprehension” as opposed to “direct ostensive apprehension.” Thus, Leibniz unmistakably disambiguates Descartes’s model in favor of a precise intellectual model. The empiricists, by contrast, correspondingly disambiguate Descartes’s conception in favor of an entirely sensible model.Tradicionalmente, a teoria moderna das idéias foi discutida principalmente em conexão com a sua suposta introdução de um véu de itens mentais entre a mente e o mundo que leva, por meio dos empiristas, ao ceticismo radical sobre a existência de um mundo externo. Aqui eu proponho enfatizar um aspecto completamente diferente da teoria Cartesiana das idéias que, na minha visão, é mais fundamental no que diz respeito a abrir o caminho empirista que conduz ao ceticismo radical de Hume. Eu argumento que o que eu chamo de o modelo de “apresentação fenomenológica” de justificação última está baseado em uma ambigüidade fundamental entre apreensão sensível e intelectual insinuada pela visão de Descartes de idéias “claras e distintas” junto com a sua ênfase na prioridade da intuição sobre inferência lógica. A apreensão sensível confia no contato imediato com itens presentes fenomenologicamente e ostensivamente perante a mente como particulares dados. O modelo de apresentação fenomenológica está inspirado na apreensão sensível, embora os itens que se apresentam perante a mente poderiam ser eles mesmos idéias do entendimento, figuras da imaginação, impressões sensórias, ou objetos externos materiais. A apreensão intelectual, por contraste, como eu ilustro com o modelo de Leibniz de nosso conhecimento de conceitos e verdades da razão, consiste na compreensão discursiva e não-ostensiva da generalidade de conceitos abstratos e de estruturas formais . Para Leibniz, toda a apreensão intelectual é claramente “apreensão discursiva lógica” por oposição a “apreensão ostensiva direta”. Assim, Leibniz claramente desfaz a ambigüidade do modelo de Descartes em favor de um modelo intelectual preciso. Os empiristas, por contraste, desfazem a ambigüidade da concepção de Descartes em favor de um modelo completamente sensível. (shrink)

A central debate in early modern philosophy, between empiricism and rationalism, turned on the question which of two cognitive faculties—sensibility or understanding—should be accorded logical priority in an account of the epistemic credentials of knowledge. As against both the empiricist and the rationalist, Kant wants to argue that the terms of their debate rest on a shared common assumption: namely that the capacities here in question—qua cognitive capacities—are self-standingly intelligible. The paper terms this assumption the Layer-Cake Conception of Human Mindedness (...) and focuses on Kant’s argument against the empiricist version of the assumption, in particular, as that argument is developed in the B version of the Transcendental Deduction in the Critique of Pure Reason. The paper seeks to show how a proper understanding of the structure of the B Deduction reveals its aim to be one of making sense of each of these two capacities (sensibility and understanding) in the light of the other. For the front of the argument that is directed against the empiricist, this means coming to see how a reading of the text that is informed by the layer-cake conception (and which therefore takes the Transcendental Aesthetic to furnish us with the full story about the nature of our faculty for sensory apprehension) is mistaken. For the front of the argument which is directed against the rationalist, this requires coming to see how a mere inversion of the central claim of such a reading would be equally wrong. It would require seeing how a discursive faculty of understanding able to traffic in nothing more than empty concepts would no more amount to a genuinely cognitive power than would a faculty of intuition able to traffic in nothing more than blind intuitions. That is, it requires seeing how each of these faculties depends on its relation to the other to be the sort of faculty that it is in a finite rational being. (shrink)

“Sensation’s Ghost” identifies one type of non-sensory experience, the quasi-feelings that attend perception, inflecting them vaguely and globally. Following Husserl, I suggest that non-sensory awareness includes much more than the fringe elements Mangan discusses. Every perceptual property can be either sensed, or apprehended in a non-sensory manner. Non-sensory apprehensions are nonetheless part of the occurrent conscious awareness of objects and scenes.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.1 (2002) 125-142 [Access article in PDF] Hölderlin's Poetic Self-consciousness James H. Donelan Nur ihren Gesang sollt' ich vergessen, nur diese Seelentöne sollten nimmer wiederkehren in meinen unaufhörlichen Träumen. I should forget only her song, only these notes of the soul should never return in my unending dreams. Hölderlin, Hyperion I FOR MANY YEARS, Friedrich Hölderlin has occupied a crucial position in both literary and philosophical (...) history. Well-known literary theorists, such as Walter Benjamin, Peter Szondi, and Paul de Man, have described him as the poet who made the transition from German Classicism to Romanticism. Several major philosophers, including Dieter Henrich and Manfred Frank, claim that Hölderlin's insights into Kantian and Fichtean metaphysics were vital to Schelling's and Hegel's far more famous accounts of subjectivity. Either contribution alone would make Hölderlin an important figure in intellectual history; it is almost miraculous that he managed both, especially when one considers the brevity of his career, a span of only ten or twelve productive years.What accounts for this remarkable dual achievement? Historical accident and tremendous talent give us only a partial answer. Hölderlin was fortunate to have Hegel and Schelling as close friends at the Tübinger Stift, and to move to Jena precisely when it had become a center for new thinking in both literary and philosophical circles. He had enormous ability both for ancient Greek and poetic meter, allowing him to benefit from his predecessors and his contemporaries [End Page 125] in remarkable ways. However, his parallel accomplishments in philosophy and poetry are linked by more than just happenstance and genius. In my view, they represent the continuous development of a solution to a single problem, that of self-consciousness, realized in poetic form through an idea of music. For Hölderlin, making the transition from philosopher to poet required him to establish a connection between Idealist theories of self-consciousness and the material world. To meet this challenge, he constituted himself as a self-conscious poet through both theoretical and actual poetic creations, and constituted a musical-poetic voice, or Gesang, within his poetry as a means of joining the abstractions of philosophy with the concrete voice of the poet.The background of this transformation lies in the complex history of the idea of self-consciousness, or subjectivity. In the early Idealist accounts of self-consciousness of Kant and Fichte, the subject recognizes its existence by juxtaposing itself with an object. However, the nature of this object, and the connection between the abstract, theoretical construction of the subject and the actual, practical experience of the conscious self posed a problem that neither philosopher solved definitively. For Kant, self-consciousness emerges from a pre-reflective sense of the self's existence as the subject of different experiences of phenomena over time; self-consciousness therefore arises from a deduction of empirical experience. However, this formulation contains a surprisingly belated and unmotivated version of the self, with no clear account of its origin.Fichte answered the question about the origin of the self by stating that the self posits itself through its opposition to a material object, a non-self he calls the Nicht-ich, and becomes self-conscious by differentiating the Ich from the Nicht-ich and declaring "I am I." Fichte's explanation of self-consciousness as an act rather than an entity nevertheless relies on a kind of solipsism and still does not sufficiently address the ultimate cause of the process. The Ich that declares its own existence must distinguish itself from the Nicht-ich somehow; the relation between the two terms presupposes a subject that already possesses sensory apprehension to create the distinction between Ich and Nicht-ich necessary for the initial positing of the self.Either explicitly or implicitly, both Kant's and Fichte's versions of subjectivity rely on the category of the aesthetic, defined as the experience of precognitive sensation in general, to mediate the encounter between subject and object. Kant later expanded his inquiry [End Page 126] into... (shrink)

Fales defends the doctrine of the given against the Sellarsian dilemma. On his view, sensory experiences, to which one has direct access, can justify basic beliefs. He upholds this view by way of defending an expansive conception of inference, according to which a broadly inferential relation can hold between sensory experiences and perceptual beliefs. The purpose of this paper is to show that Fales’s defense of the given fails. For this purpose, I argue that there are two requirements (...) for being a good reason, and that his conception of direct apprehension faces a serious dilemma with regard to these requirements. In addition, I argue that his expansive conception of inference is unfounded. (shrink)

Intuition is sometimes derided as an abstruse or esoteric phenomenon akin to crystal-ball gazing. Such derision appears to be fuelled primarily by the suggestion, evidently endorsed by traditional rationalists such as Plato and Descartes, that intuition is a kind of direct, immediate apprehension akin to perception. This paper suggests that although the perceptual analogy has often been dismissed as encouraging a theoretically useless metaphor, a quasi-perceptualist view of intuition may enable rationalists to begin to meet the challenge of supplying a (...) theoretically satisfying treatment of their favoured epistemic source. It is argued, first, that intuitions and perceptual experiences are at a certain level of abstraction the same type of mental state, presentations, which are distinct from beliefs, hunches, inclinations, attractions, and seemings. The notion of a presentation is given a positive explication, which identifies its characteristic features, accounts for several of its substantive psychological roles, and systematically locates it in a threefold division among types of contentful states. Subsequently, it is argued that presentations, intuitive no less than sensory, are by their nature poised to play a distinctive epistemic role. Specifically, in the case of intuition, we encounter an intellectual state that is so structured as to provide justification without requiring justification in turn—something which may, thus, be thought of as ‘given’.

Does inner sense, like outer sense, provide inner sensations or, in other words, a sensory manifold of its own? Advocates of the disparity thesis on inner and outer sense claim that it does not. This interpretation, which is dominant in the preexisting literature, leads to several inconsistencies when applied to Kant’s doctrine of inner experience. Yet, while so, the parity thesis, which is the contrasting view, is also unable to provide a convincing interpretation of inner sensations. In this paper, (...) I argue that this deadlock can be traced back to an inadequate understanding of inner sense shared by both sides. Drawing upon an analysis of the notion of obscure representations, I offer an alternative interpretation of inner sense with a special regard to self-affection, apprehension, and attention. From this basis, I will infer that outer sense delivers sensory content that is initially and intrinsically unaccompanied by phenomenal consciousness; inner sense contributes by endowing such content with phenomenal consciousness. Therefore, phenomenal qualities can be regarded as the sensory manifold of inner sense. This alternative interpretation solves the long-standing dispute concerning inner sensations and would further illuminate Kant’s notion of inner experience. (shrink)

The paper deals with our ability to classify objects as being of a certain kind on the basis of information provided by the senses (empirical classification) and to ascribe empirical predicates to objects on the basis of these classificatory verdicts (empirical predication). I consider, first, the project of construing the episodes in which this ability is exercised as involving universals. I argue that this construal faces epistemological problems concerning our access to the universals that it invokes. I present the empiricist (...) strategy for dealing with these problems by appeal to sensory qualities, and argue that it rests on a mistake. Then I turn to sketching an account of our faculty of empirical classification and predication which doesn't invoke universals. The account takes as its starting point the nominalist construal of sense experience to be found in the work of C. I. Lewis and Nelson Goodman. I argue that this construal has the resources for explaining some of the central features of the practice of empirical predication. There are those who feel that our ability to understand general terms ... would be inexplicable unless there were universals as objects of apprehension. And there are those who fail to detect, in such appeal to a realm of entities over and above the concrete objects in space and time, any explanatory value. W. V. O.

Kant uses terms translatable as ‘synthesis’ and ‘perception’ in different ways in different contexts, which suggests that there are different kinds of synthesis and perception. I propose that there are two main basic functions of perception according to Kant: that of singling out a thing and that of getting perceptually informed about the configuration of the thing’s perceptible features. I argue that the first function is not dependent on the kinds of syntheses Kant analyzes in the Critique of Pure Reason (...) but grounds any such synthesis. I also argue that if singling out a thing is considered to involve synthesis, then the term ‘synthesis’ is identified with a unification of sensory information itself, which is not of much consequence for the transcendental philosopher. The paper also aims to clarify what ‘manifold’ consists in and what the starting point of the ‘synthesis in apprehension’ might be. (shrink)

Early modern commentaries on Aristotle’s Metaphysics contain a lively debate on whether experience is ‘rational’, so that it may count as ‘proto-knowledge’, or whether experience is ‘non-rational’, so that experience must be regarded as a primarily perceptual process. If experience is just a repetitive apprehension of sensory contents, the connection of terms in a scientific proposition can be known without any experiential input, as the ‘non-rational’ Scotists state. ‘Rational’ Thomists believe that all principles of scientific knowledge must rely on (...) experiential data, because experience consists in an apprehension of facts rather than objects. And it is only apprehension of facts that can justify knowledge of principles. In this context, the role of mathematical knowledge is special, because it is self-evident. So Thomists must either show that mathematical principles do rely on experience, or that they do not express knowledge claims. (shrink)

This dissertation examines the theory of perceptual cognition laid out by the 7th century Buddhist scholar, Dharmakīrti, in his magnum opus, the Pramāṇavārttika. Like most theories of perception, both ancient and modern, the sensory cognition of ordinary objects is a topic of primary concern. Unlike other theorists, however, Dharmakīrti advances a technical definition of “perception” as a cognition which is both nonconceptual and non-erroneous. Dharmakīrti’s definition of perception is thereby deliberately inclusive of three additional types of “perceptual” cognition, in (...) addition to veridical sensory awareness: the nonconceptual mental apprehension of an immediately-preceding cognition (“mental perception”), the vivid appearance of soteriologically efficacious objects of contemplative practice (“yogic perception”), and the sheer unmediated presence of the contents of cognition—whatever these might be—to the cognizing mind (“reflexive awareness”). Through the logical examination of what it means to be aware of an object, Dharmakīrti demonstrates that the awareness of an object is just the awareness of a phenomenal form or cognitive image produced by that object. Pursuing this analysis further, however, Dharmakīrti argues that the very notion of an object of cognition that exists “externally” or outside the mind is incoherent. Additionally, Dharmakīrti maintains that the phenomenological structure of subject and object—that is, the “first-personal” sense of one’s own cognitions as pertaining to oneself (“for-me-ness”), together with the inseparably concomitant sense that the objects of cognition exist “out there” in an extramental world—is strictly a form of cognitive error. Therefore, because ordinary sensory cognition is inherently structured by this subject-object duality, ordinary sensory cognition must in the final analysis be understood as erroneous. According to Dharmakīrti, in other words, ultimately only the nondual “luminosity” of reflexive awareness is genuinely perceptual, because only reflexive awareness is undistorted by nature. In this way, Dharmakīrti’s epistemology provides a theoretical foundation for the advanced nondual contemplative practices of Indian and Tibetan Buddhism, particularly Mahāmudrā and rDzogs chen.

According to much recent work in metaethics, we have a perceptual access to normative properties and relations. On a common approach, this access has a presentational character. Here, ‘presentational’ specifies a characteristic feature of the way aspects of the environment are apprehended in sensory experience. While many authors have argued that we enjoy presentations of value properties, thus far comparatively less effort has been invested into developing a presentational view of the apprehension of normative reasons. Since it appears that (...) this view would offer much the same theoretical benefits as presentational views of the apprehension of value, it seems worthwhile redressing this imbalance. My paper aims at doing so, focusing on concern-dependent practical reasons. After clarifying the central commitment of this view, I assess a recent proposal by Dancy :787-812, 2014) which provides a detailed characterization of the relevant type of cognition. I argue that Dancy ignores one of the central features of a presentational access to normative reasons and therefore misidentifies which actual psychological phenomena are apt to play this role. In this context, I also assess and reject further candidates that might seem fitting for this purpose. In the remainder of the paper, I then offer a more adequate account which specifies an actual form of presentational access to concern-dependent practical reasons and provide the contours of a more substantive account of its nature.

The city of Johannesburg pulsates with rhythms that are driven by some of its most fundamental characteristics: pressured economic activity, the mingling and movement of bodies, commuting, and a history of race and class segregation. The collaborative Jozi Rhythmanalogues project attempts to make sense of these rhythms by employing sensory experience as a process of explorative thought. In the course of this project, public spaces are documented over long periods through time-lapse films, which are analysed to reveal patterns of (...) movement. The resulting graphs, representing a kind of ‘automatic writing’ of the city’s rhythms, are interpreted as a graphic score by musical ensembles, producing music, sound and noise. This article reflects on the explorations of spaces, methods and concerns that has led to the development of the Jozi Rhythmanalogues project’s different manifestations, and looks at the ways in which two very different ensembles have interpreted the graphic score. The key questions that emerge relate to the nature of the information that is captured or ‘written’ in the graphs, and what it means to attempt, over and over, to make sense of this information. The idea of ‘sensory thought’ is critical here, as the project in its entirety is concerned with the work of the senses as a thinking process. This phenomenological angle is complicated by the flirtation with abstract data in the measurements that comprise the production of the graphs, revealing a question of movement between poetic and analytical modes of apprehension.

Traditionally the modern theory of ideas has been discussed primarily in reference to its alleged introduction of a veil of mental items between the mind and the world, which leads, through the empiricists, to radical skepticism about the existence of an external world. Here I propose to emphasize an entirely different aspect of the Cartesian theory of ideas which, in my view, is more fundamental in opening the empiricist path that leads to Hume’s radical skepticism. I argue that what I (...) call the “phenomenological presentation” model of ultimate justification is rooted in a fundamental ambiguity between sensible and intellectual apprehension insinuated by Descartes’s view of “clear and distinct” ideas together with his emphasis on the priority of intuition over logical inference. Sensible apprehension relies on immediate acquaintance with items phenomenologically and ostensively present before the mind as given particulars. The phenomenological presentation model takes its clues from sensible apprehension, although the items present before the mind might themselves be either ideas of the understanding, images of the imagination, sensory impressions, or material external objects. Intellectual apprehension, by contrast, as I illustrate with Leibniz’s model of our knowledge of concepts and truths of reason, consists in the discursive, non-ostensive grasping of the generality of abstract concepts and of formal structures . For Leibniz, all intellectual apprehension is unambiguously “logical discursive apprehension” as opposed to “direct ostensive apprehension.” Thus, Leibniz unmistakably disambiguates Descartes’s model in favor of a precise intellectual model. The empiricists, by contrast, correspondingly disambiguate Descartes’s conception in favor of an entirely sensible model. (shrink)

Suggestions and arguments put forward by the philosophers Herbert Feigl, Paul Feyerabend, Richard Rorty, and Paul Churchland are critiqued as to the feasibility of a “direct,” quasi-perceptual apprehension of neural states through neuroscience-informed introspection. The conceptual origins of this presumptuous direct introspecting are shown to be derivative from a scientifically inadequate theory of philosophical realism. Direct perception and its integral realist theory, as well as an analogical equation of perception with introspection, are focused as to their inherent intelligibility and coherence (...) with sensory psychology. Claims of nominal intertheoretic identities are reviewed as to possible mind–brain applications. A summary elucidation of the known nature of perception and its phenomenology reveals that though there may be an initial plausibility given to a projected direct introspection of brain from a supposed equally direct perception of stimuli, once the latter is definitively rejected from considerations of psychology, so its extrapolation to nominal brain introspection must be rejected.

This article engages the anthropological assumptions underlying the apprehensions and promises associated with language in artificial intelligence (AI). First, we present the contours of two rivalling paradigms for assessing artificial language generation: a holistic-enactivist theory of language and an informational theory of language. We then introduce two language generation models – one presently in use and one more speculative: Firstly, the transformer architecture as used in current large language models, such as the GPT-series, and secondly, a model for 'autonomous (...) machine intelligence' recently proposed by Yann LeCun, which involves not only language but a sensory-motor interaction with the world. We then assess the language capacity of these models from the perspectives of the two rivalling language paradigms. Taking a holistic-enactivist stance, we then argue that there is currently no reason to assume a human-comparable language capacity in LLMs and, further, that LeCun's proposed model does not represent a significant step toward artificially generating human language because it still lacks essential features that underlie the linguistic capacity of humans. Finally, we suggest that proponents of these rivalling interpretations of LLMs should enter into a constructive dialogue and that this dialogue should continuously involve further empirical, conceptual, and theoretical research.

According to St. Thomas, the natures of material things are the proper objects of human understanding.Thomas claims only that the natures of things are the proper objects of the intellect, not that they are its only objects: he does not deny that we have intellective cognition also of the contingent states and situations of particular material things. And he holds that, at least in this life, humans cognize these natures, not through innate species or by perceiving the divine exemplars, but (...) only by abstraction from phantasms (ST Ia, 84.7, 85.1).This claim applies to the exercising of concepts already acquired, as well as their initial acquisition (ST Ia 84.7). Here and throughout, I use “cognition” to translate “cognitio.” As Scott MacDonald (“Theory of Knowledge” in Cambridge Companion to Aquinas, ed., N. Kretzmann and E. Stump [Cambridge: Cambridge University Press, 1993], p. 162) points out, translating “cognitio” with “knowledge” is misleading, given that cognitiones can, on Thomas’s account, be false (see, for example, ST Ia 17.3). I discuss Aquinas’s conception of cognition in section I.1. More precisely, the human intellect’s active component, the agent intellect, produces cognition of the natures of material things by abstracting intelligible forms from phantasms and informing them on its passive component, the possible intellect, to actualize the latter’s potency to understand.This division of the intellect into an active and a passive component originates in Aristotle’s cryptic remark that in the soul “there is a mind for becoming all things” and “a mind for producing all things” (DA III 5, 430a10). This passage has been subject to myriad interpretations. Aristotle’s Arabic commentators read him as saying that (one or both) of these intellects are single and separate from individual human souls. In opposition to these interpretations, Aquinas holds that the agent and possible intellects are both immanent powers of each individual soul. Since these interpretations enjoyed considerable popularity in Aquinas’s day, we often find him developing his account of the human intellect in explicit opposition to them (cf. OUIAA). The aim of the present piece is to clarify Thomas’s account of this intellective abstraction, and thereby the precise force of the conceptual empiricism it asserts.Important recent work by several scholars has advanced our understanding of many central aspects of Aquinas’s philosophy of mind and epistemology, including his account of intellective abstraction. See Eleonore Stump, “Aquinas on the Foundations of Knowledge,” Canadian Journal of Philosophy (Supplementary Volume) 17 (1992); “Aquinas’s Account of the Mechanisms of Intellective Cognition,” Revenue Internationale de Philosophie 52 (1998): 287–307; “Aquinas on Sensory Cognition,” in Medieval Analyses in Language and Cognition, eds. Sten Ebbesen and Russell L. Friedman, volume 77 in the series Det Kongelige Danske Videnskabernes Selskab, Historisk-Filosofiske Meddelelser (Copenhagen: Munksgaard, 1999), pp. 377–395. Norman Kretzmann, “Infallibility, Error, and Ignorance,” Canadian Journal of Philosophy 17 (1992); Kretzmann, “Philosophy of Mind,” in Cambridge Companion to Aquinas; Robert Pasnau, Theories of Cognition in the Later Middle Ages (Cambridge: Cambridge University Press, 1997); and Scott MacDonald (“Theory of Knowledge,” in Cambridge Companion to Aquinas).Many of these discussions share a salutary focus on Aquinas’s claims regarding the reliability of our faculties, so that their treatments of intellective abstraction tend to center on his prima faciae wildly implausible claim to its infallibility: “The proper object of intellect is the quiddity of a thing, and this is why intellect is not fallible regarding the quiddity of a thing, speaking of it just as such” (ST Ia 85.6). Kretzmann provides an interesting and detailed treatment of this claim. Drawing on a range of texts, he argues that the intellect’s apprehension of the quiddity of a thing is such that one acquires an initial, crude concept of that thing, and that this apprehension must be distinguished from the intellect’s act of compounding, in judgments, the aspects of things so apprehended: it is only through a fallible, and extended process of making such judgments that we arrive at more adequate concepts of things (see the final section of “Infallibility, Error, and Ignorance”). MacDonald also makes insightful, and complementary, observations along similar lines (pp. 183–84). However, though helpful, these points do not suffice to explain, let alone render defensible, Thomas’s claim of infallibility: why can’t some of our acts of intellective abstraction yield false cognitions (however rudimentary), in the sense Thomas specifies?; in other words; why can’t the agent intellect sometimes produce in the possible intellect forms which do not correspond to the forms that actually inhere, or even could inhere, in material things? I think that Stump is right to take this optimism to be one striking instance of Thomas’s general epistemic optimism rooted in his conviction that God designed our cognitive faculties (Stump, “Foundations of Knowledge,” pp. 145–48).The interpretation of his intellective abstraction provided here complements Stump’s insight. For it, in effect, elaborates how Aquinas’s theistic metaphysics grounds his epistemic optimism about the first operation of our intellect. In particular, it explains how the agent intellect, as the human participating likeness in the divine light of understanding, has the active potency to order phantasms in such a way that it can produce in the possible intellect intelligible species which are determinate likenesses of the particular material things of which we have experience (cf. Section III iv, below). Examining his distinction between sensible and intellectual cognition, and his account of the way the former, in phantasms, supplies the data for intellective abstraction, will lead us to reassess the nature of Thomas’s antinativism—arguably the most important historical and philosophical legacy of his cognitive psychology.

Lewis's account of the role of sensory experience in empirical knowledge rests on the theses: (1) that one's apprehension of what is given in sensory experience is certain; (2) that unless there were such certain apprehension of the given, No knowledge would be possible; (3) that justification of one's other justified empirical beliefs always derives from one's apprehension of the given. I show that all three theses are false. That they are false provides further motivation for the theory (...) of justification I call "foundherentist", Which is fallibilist and permits mutual support (see my "theories of knowledge; an analytic framework", "proceedings of the aristotelian society, Lxxxiii", 1982-3).

According to [Edward T.] Cone, then, there is a great deal of music written today that is simply no longer susceptible to analysis. If this is true, it can mean one of several things. First, it may indicate that, although there are new compositions that one finds interesting and representative of the period in which we live, the music simply does not lend itself to analysis. Thus, even if we enjoy and admire this music, there is not much that we (...) can say about it beyond perhaps a mere description—which I think most of us, along with Cone, would agree does not really constitute an analysis. I have the impression that many proponents of new music hold this view—that is, they feel that new music is understandable only through a sort of mindless apprehension of its sensory surface. But if this is a fair account of the situation surrounding new music, it seems to me to represent a very serious—and also depressing—state of affairs. For what it means, I suspect, is that new music does not lend itself to being thought about in any serious way at all; and if so, then new music is missing a crucial dimension—namely, an accompanying conceptual framework, erected through a body of critical and theoretical discourse, through which its meaning is defined and redefined as our thinking about music evolves. Indeed, this dimension forms—and has always formed—such an integral component of Western art music that its absence would seem to indicate that music, at least as we have known it, is in all likelihood dead. Robert P. Morgan is professor of music theory and composition at Temple University. In addition to being a composer, he is active as a critic; his articles on contemporary music have appeared recently in several music journals and in An Ives Celebration. His contribution to Critical Inquiry, "Musical Time/Musical Space" appeared in the Spring 1980 issue. (shrink)

The supposed communication of one mind with another at a distance, without any means known to physical or psychological science, is a generally accepted definition of telepathy. Thus when persons sensorially isolated from each other experience congruence and coincidence of thoughts, emotions or actions they are considered as being in telepathic communication. Clairvoyance surmises the apprehension of particular objects and stimuli also without the employment of any of the agencies of the five senses. Although telepathy and clairvoyance have been thus (...) recognized as distinct conjectures, either or both comprise features of Extra Sensory Perception. Both are conceived of as transcending the anatomical structures and physiological functionings that comprise the five senses. They therefore constitute a mysterious, additional sense which as yet cannot be ascribed to material bases or causes. However, the operations, if not the exact natures, of these recondite abilities have been, it is claimed, experimentally and precisely ascertained. (shrink)

RESUMEN El debate central en filosofía de la imagen se articula en torno a la oposición entre un enfoque semiótico, que considera a la imagen como un determinado tipo de signo, y uno perceptualista, que se orienta hacia la captación de imágenes y la caracteriza en su relación con la percepción sensible. Se señalan algunas dificultades de dicha articulación y se analiza el enfoque hermenéutico y la ontología heideggeriana de la imagen para mostrar cómo puede contribuir a renovar el debate, (...) afectando incluso su pregunta conductora. ABSTRACT The central debate in the field of philosophy of mage concerns the opposition between a semiotic approach, which considers images to be a certain type of signs, and a conceptualist approach, focused on the apprehension an images and its relation to sensory perception. The article points out some of the difficulties of this formulation and analyzes Heidegger's hermeneutical approach and ontology of the image in order to show how it can contribute to enriching the debate and even modify its guiding question.

This paper examines three propositions: “First to arise within intellectual awareness is the notion of Being”; the human being is defined as “the rational animal”; and knowing involves “the complete return of the subject into itself.” Its starting point is an examination of what seems trivial: the letter ‘F’ in ‘First.’ It involves eidetic recognition of the alphabet and is identically the same, not only in different times and places and in different type-faces or hand-written form, but in differing media: (...) visual, audile, tactual. And eidetic recognition is also involved in the terms into which the letters or sounds or embossings enter, each of which is definable in terms of other terms which, in turn, are definable in other terms until we see that the whole itself is articulated in terms of the interlacing of meanings. What grounds such recognition is the openness to the whole introduced by the notion of being. The unrestrictedness of the openness is paralleled by the coemergence of the principle of noncontradiction which governs coherent discourse. In both sensory presentation and intellectual apprehension we are outside our spatial inside, with the things manifest in the environment and in terms of the world of public meaning expressed in language. The second part of the paper traces the various options for understanding the notion of being in the history of Western thought: Parmenides, Plato, Aristotle, Aquinas, Scotus, Spinoza, Hegel, Nietzsche, Heidegger, and Derrida.

Ernst Cassirer viewed mythical thinking as a first step in our mental representation of the real world, but only a first step. What myth leaves out are the differentiations that lead eventually to science. To the primitive, mythically inclined mind, the world is an undifferentiated whole, the elements of which—including the mind itself—are thought to be concrete and interconnected. This means that there is no distinction between observer and observed, and that the observer sees the representations with which she constructs (...) her picture of reality as direct apprehensions of reality, untnediated by any sensory or cognitive categories. Far as that way of thinking may seem from the modern mindset, we have only to examine commonplace political ideas to find evidence of the implicit assumption of an unmediated connection between the wishes of poltical agents and the results they intend to achieve.

This paper will address one of the “unsolved” problems that has traditionally been called the “form/content” dualism. Husserl writes in Ideas I: “This remarkable duality and unity of sensory hyle and intentional morphe plays a dominant role in the whole phenomenological sphere (in the whole sphere, namely within the stage of constituting temporality, which can be constantly verified)” (Hua III, 192). To be sure, Husserl has defined the sensory hyle “descriptively” as the really immanent [reell] part of consciousness (...) with differences of color, sound, touch and so on, as well as “functionally” as something that can become an adumbration or an aspect of objects through the animating apprehension of active consciousness. But the constitution of an object in his later analysis is clarified more and more in terms of noematic unification (Holenstein, 93), which obscures the function of hyle in the process of constitution.

This paper deals with the problem of the origin of sense and meaning. For Husserl, the determination of the ideal identity of something new can only take place retroactively in the totality of the preceding series by stepping back towards the original foundation of sense. In this regard, J. Derrida questions the ideality of the same as presence and the possibility of retrieving any arché of sense in his writings Speech and Phenomena and Edmund Husserl’s Origin of Geometry. Phenomenology is (...) not oblivious to these difficulties, as results from a closer reading of the correlation between idealities and sensory experience: It will show that there are at least four interrelated gaps in the Husserlian phenomenology which testify the difficulty in grasping a retraceable arché of sense. First, the gap between the ideality of sense and its representation. Second, the gap between sensory and categorial intuitions, whereby both exceed one another. Third, the gap between the ideality of sense and the sense which exceeds our expectations. Fourth, the gap between the experience of the new that overcomes us and its apprehension by consciousness. Hence, there is a fundamental gap between the conceptual idealities and the essential indeterminacy of our phenomenological sensory experience, which is correlative to an excess of one in respect to the other. In this sense, Derrida’s concepts of « différance » and “invention” allow us to conceive of this self-givenness of sense as the expression of its constant self-renewal. This expression takes the form of a trace, which, neither present nor absent, suspends meaning and full presence, leaving the narrative “open” for the reinvention of sense. (shrink)

With an Essay on Consciousness appeared anonymously in mid-summer 1728 over the prestigious imprint of Tonson in the Strand. 1 The "Essay on Consciousness" explicates the nature and functions of consciousness. The two dissertations modestly prepare for an inquiry into human understanding, which [End Page 639] is at present very much wanted; and towards which the removal of those Prejudices arising from Sense, and the Imagination, which hinder Men from discovering the Truth, or discerning it, tho' fairly offered to them, is the first Step to be made; and may be of some use to any one who shall hereafter undertake to explain and set forth, in a clear and perspicuous Light, the native and genuine Operations of the Understanding, as they are in Themselves, without mixing or confounding them with any Others. (1-2) A Bibliothèque raisonnée review twice noted the book's diffusion and inconvenient organization. 2 The book is nonetheless interesting for its clear defense of the cognitive superiority of reason over sense and imagination, its attack on contemporary conflations of human and brutal natures, and its treatment of consciousness, dreams, madness, and the self. In its assay of human understanding Two Dissertations implements Peripatetic, Cartesian, and even Lockean principles. The last notwithstanding, the work is an assault on the Lockean reduction of understanding to passive perception and on Locke's conception of knowledge as the perception of ideas and their relations. It is also an attempt to resuscitate reason in the teeth of nominalist accounts of rationality such as those of John Toland and allied freethinkers. 3 In pursuing these goals, it offers variations on traditional concepts of cognition, such as a conception of notions as acts of intellectual apprehension which an interpreting mind brings to bear on sensory appearances. This understanding of notions as acts falls within the British notional way marked by Digby, White, Sergeant, and especially Burthogge, antedating publication of George Berkeley's explicit distinction between passive ideas and notions owing to reflection. 4 Notions play an important role in Two Dissertations, contrasting the mind's active, rational contribution to knowledge with Lockean ideas. Yet the work's treatment of notions contains intimations of a more elaborate conception of rationality that includes a distinct order of reflective notions not deployed in this book (25-26).Clearly identifying the purposes, doctrine, and authorship of Two Dissertations is worthwhile insofar as its detailed analysis of consciousness is intrinsically interesting and quite possibly historically important, despite its neglect in the past century. For its "Essay on Consciousness" purports to be the "first Attempt that hath been made on the Subject" (sig. A3r ; cf. 141-42). While conventional [End Page 640] interpretations of modern philosophy may have habituated us to be skeptical of such a claim made as late as 1728, it is by no means outlandish, subject to textual and conceptual qualification. This paper concerns primarily just one function of the conscious mind addressed in Two Dissertations: the concept of... (shrink)

: Recently developed projective models of consciousness and its contents challenge received schemas in which all contents of consciousness are held to be well contained in the skull. Working our way into this from several angles, it becomes evident that there are inconsistencies in how we frame classes of mental contents which are arguably equivalent in being. Particular examples of imagery, of dancing and of words, are brought forward to highlight the clash in our apprehensive assumptions, focusing on possible cognitive (...) as well as psychological costs of such inconsistency. A coherent way to blend the container and projector schemas is pointed out; yet such a blend does not support the standard claim for any kind of purely inner voice, contained but not projected. Conscious reflection may in all instances depend on projection, with reflection in imagery - visual, audible, even tactile and otherwise felt - placed just the far side of what can schematically be grasped as the sensory horizon where, in the space-time just beyond here and now, our imaginative expectations backstop recognition of here-now present things. Resumo: Os modelos projetivos de consciência e de seus conteúdos, recentemente desenvolvidos, desafiam os esquemas tradicionais, nos quais todos os conteúdos da consciência são mantidos bem contidos dentro do crânio. Trabalhando desta forma, a partir de vários ângulos, torna-se evidente que existem inconsistências na forma como emolduramos classes de conteúdos mentais que são possivelmente equivalentes em seu ser. Exemplos particulares de imagens, de dança e de palavras são apresentados para ressaltar o choque em nossas suposições apreensivas, focalizando possíveis custos cognitivos e psicológicos de tal inconsistência. Uma maneira coerente de misturar os esquemas do “continente” e do “projetor” é apontada; no entanto, tal combinação não suporta as exigências gerais, encontradas na literatura, para qualquer tipo de fala puramente interna, que esteja contida, mas não projetada. A reflexão consciente pode, em todos os casos, depender da projeção, com reflexo na imagem - visual, audível, até tátil e sentida - situada apenas no lado distante do que pode ser esquematicamente compreendido como o horizonte sensorial onde, no espaço-tempo e agora, nossas expectativas imaginativas apóiam o reconhecimento das coisas presentes e atuais.

This paper explores Landmann-Kalischer’s analogy between the sensing of secondary qualities and the feeling of values in her work “Philosophie der Werte” (Philosophy of Values) (1910). Attention is paid to the epistemic motivation of the analogy, the distinction between pure feelings and affects, and the relation of pure feelings to value judgments. Her account is contrasted with two other accounts of the Brentanian tradition: Scheler’s approach within early phenomenology and Meinong’s account within the Graz School. I demonstrate that Landmann-Kalischer’s pioneering (...) work helped to forge a new view of affectivity which became dominant among Brentano’s followers. According to this new view, there is a type of affective experience which is both intentional and cognitive. More precisely, she argued that the affective experience in question is a feeling. The paper also argues that her account can enrich today’s meta-ethical research. It is argued that her account of pure feelings provides arguments against the view that makes emotions responsible for the apprehension of value. Furthermore, it is shown that we need an analysis of how objective knowledge of value can be obtained from our affective intuitions. -/- . (shrink)

Sensory Individuals: Unimodal and Multimodal Perspectives provides an interdisciplinary, well-balanced, and comprehensive look at different aspects of unisensory and multisensory objects, using both nuanced philosophical analysis and informed empirical work. The research presented in this book represents the field's progression from treating neural sensory processes as primarily modality-specific towards its current state of the art, according to which perception, and its supporting neural processes, are multi-modal, modality-independent, meta-modal, and task-dependent. Even within such approaches sensory stimuli, properties, brain (...) activations, and corresponding perceptual phenomenology can still be characterized in a modality-specific way. The book examines the basic building blocks of human perception, and whether they are best understood as sense modality dependent units of different forms or multimodal perceptual objects. The book combines a variety of innovative and integrative angles to explore the topic and acts as a catalyst for an increasingly diverse field of research, which is in an exciting phase of growth and advancement. New questions are arising as quickly as they are being answered, and the collection Sensory Individuals provides an original and up-to-date addition to the field. (shrink)

Many philosophers doubt that one can provide any successful explanation of sensory qualities - of how things look, feel, or seem to a perceiving subject. To provide such an explanation, one would need to explain qualitative facts in non-qualitative terms. Attempts to construct such explanations have seemed, in principle, doomed. Austen Clark examines the strategy used in psychophysics, psychometrics, and sensory neurophysiology to explain qualitative facts. He argues that this strategy could succeed: its structure is sound, and it (...) can answer the various philosophical objections lodged against it. On this basis Professor Clark presents an analysis of senosry qualities that offers the possibility of explaining at least some qualia, and he sketches how this scheme might eventually reduce to neurophysiology. If he is correct, we are not doomed to an eternity of mere acquaintance with our qualia. (shrink)

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean-style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. (2016) presented participants with two kinds of cases: Blocker cases (similar to Grice’s case involving a mirror and a pillar) and Non-Blocker cases (similar to Grice’s case involving a clock and brain stimulation). (...) They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly less agreed that seeing occurs. They thus hypothesized that folk intuitions better align with a no blocker condition than with a causal condition. This paper continues this line of enquiry with two new experiments. The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean-style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition. They also provide an empirical reason to doubt the reflection defense. (shrink)

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main (...) contenders, critically compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

Plotinus maintains that our intellect is always thinking. This is due to his view that our intellect remains in the intelligible world and shares a natural kinship with the hypostasis Intellect, whose being and activity consists in eternal contemplation of the Forms. Moreover, Plotinus maintains that although our intellect is always thinking we do not always apprehend our thoughts. This is due to his view that “we“ descend into the sensible world while our intellect remains in the intelligible world. Furthermore, (...) Plotinus maintains that it is only when logoi unfold the content of our thoughts into the imagination that we apprehend them. This is due to a complex account between, on the one hand, the relationship between intellect and discursive reasoning, and on the other hand, the relationship between discursive reasoning and language. Plotinus tells this story with remarkable brevity in Ennead 4.3.30. In this paper I explain the role the imagination plays in the apprehension of thoughts through a close analysis of this treatise in connection with Ennead 1.4.10. (shrink)

Sensory substitution devices make use of one substituting modality to get access to environmental information normally accessed through another modality . Based on behavioural and neuroimaging data, some authors have claimed that using a vision-substituting device results in visual perception. Reviewing these data, we contend that this claim is untenable. We argue that the kind of information processed by a SSD is metamodal, so that it can be accessed through any sensory modality and that the phenomenology associated with (...) the use of a SSD is best described in terms of spatial phenomenology, only.

Philosophers of perception have been readier to postulate the existence of a visual field than to acknowledge sensory fields in other modalities. In this paper, I argue that the set of phenomenal features that philosophers have relied on when positing a visual field aptly characterise, mutatis mutandis, bodily sensation. I argue, in particular, that in localised bodily sensations we experience the body as a sensory field. I first motivate this claim for the case of haptic touch, and then (...) generalise it to other kinds of bodily sensation. I demonstrate the theoretical fruitfulness of this notion of a bodily field for the debate on the phenomenology of bodily ownership. (shrink)

In the paper, I argue that the notion of sensory representation that Pautz defines (via the Ramsey method) has incompatible features. The notion is defined in terms of its ability to explain both the phenomenal character of experience and its ability to give us cognitive access to perceptible properties, all while being existence-neutral. I argue that there is strong reason to conclude that no worldly relation could play all three roles simultaneously.

A recent report by Persaud et al. [Persaud, N., McLeod, P. & Cowey, A. . Post-decision wagering objectively measures awareness. Nature Neuroscience 10, 257–261] addresses a fundamental issue in consciousness science: the experimental measurement of conscious content. The authors propose a novel technique, ‘post-decision wagering’, in which subjects place bets on the correctness of decisions or discriminations. In this note, I critique the authors’ claim that their method “measures awareness directly”.

Synaesthesia is a strange sensory blending: synaesthetes report experiences of colours or tastes associated with particular sounds or words. This volume presents new essays by scientists and philosophers exploring what such cases can tell us about the nature of perception and its boundaries with illusion and imagination.
