This is a paper about The Causal Self-Referential Theory of Perception. According to The Causal Self-Referential Theory as developed by above all John Searle and David Woodruff Smith, perceptual content is satisfied by an object only if the object in question has caused the perceptual experience. I argue initially that Searle's account cannot explain the distinction between hallucination and illusion since it requires that the state of affairs that is presented in the perceptual experience must exist in order for the (...) perception to be veridical. Smith's account is interestingly different in that the descriptive content, i.e. the content that presents the perceptual object as having certain properties, does not determine the object of the experience. His account consequently does not require that the state of affairs that is presented in perception exists in order for the perception to have an object. Smith argues instead that perceptual reference is determined by a specific kind of demonstrative content. In this paper it is argued that Smith's account of demonstrative content is too indeterminate and in certain circumstances prescribes the wrong object. It is subsequently argued that the theory of demonstrative content can be modified so as to avoid these consequences. This modification involves deriving the conditions of satisfaction of seeing an object from the conditions of satisfaction of seeing the shape of the object, where the shape of the object is conceived of as a particularized property, what is also called a ‘trope’.

Combining ideas of perceptual psychologists J.J. Gibson and J.E. Cutting, moving on to answer the arguments of the "Naysayers" against autonomous and artistic meaning in photographs.

What is it, really, to pretend? What features qualify an act as pretense? Surprisingly little has been said on this foundational question. Here I defend an account of what it is to pretend, distinguishing pretense from a variety of related but distinct phenomena, such as (mere) copying and practicing. I show how we can distinguish pretense from sincerity by sole appeal to a person’s beliefs, desires, and intentions—and without circular recourse to an “intention to pretend.”.

It has been claimed in the literature that collective intentionality and group attitudes presuppose some “sense of ‘us’” among the participants (other labels sometimes used are “sense of community,” “communal awareness,” “shared point of view,” or “we-perspective”). While this seems plausible enough on an intuitive level, little attention has been paid so far to the question of what the nature and role of this mysterious “sense of ‘us’” might be. This paper states (and argues for) the following five claims: (1) (...) it is neither the case that the sense in question has the community (or “us”) in its content or as its object nor does the attitude in question presuppose a preexistent community (or “us”) as its subject. (2) The “sense of ‘us’” is plural pre-reflective self-awareness. (3) Plural pre-reflective self-awareness plays the same role in the constitution of a common mind that singular pre-reflective self-awareness plays in the individual mind. (4) The most important conceptions of plural subjects, collective persons, or group agents in the current literature fail to recognize the nature and role of plural self-awareness, and therefore fall short in important respects. (5) In spite of the striking similarities between the plural and the singular mind, there are important differences to consider. The authority of the singular first person point of view has no equivalent in the plural case. (shrink)

Philosophers have worried that research on animal mind-reading faces a “logical problem”: the difficulty of experimentally determining whether animals represent mental states (e.g. seeing) or merely the observable evidence for those states (e.g. line-of-gaze). The most impressive attempt to confront this problem has been mounted recently by Robert Lurz (2009, 2011). However, Lurz’ approach faces its own logical problem, revealing this challenge to be a special case of the more general problem of distal content. Moreover, participants in this debate do (...) not appear to agree on criteria for representation. As such, future debate on this question should either abandon the representational idiom or confront differences in underlying semantics. (shrink)

We have reason to believe that phenomenal properties are nothing over and above certain physical properties. However, doubt is cast on this by the apparent epistemic gap that arises for attempts to account for phenomenal properties in physical terms. I argue that the epistemic gap should be divided into two more fundamental conceptual gaps. The first of these pertains to the distinctive subjectivity of phenomenal states, and the second pertains to the intrinsicality of phenomenal qualities. Stoljars ignorance hypothesis (IH) attempts (...) to undermine the epistemic gap by arguing that the apparent inexplicability of the phenomenal is merely a symptom of our limited conception of the non-experiential world. I establish some obstacles to IH, and argue that the correct analysis of the epistemic gap means these obstacles can only partially be overcome. I propose, nonetheless, that IH can still be put to good use as half of a hybrid account of phenomenal consciousness. The proposal combines a self-representationalist account of the subjectivity of phenomenal states with a Russellian version of IH that accommodates the qualitative character of those states. This neo-Russellian ignorance hypothesis (NRIH) credibly undermines the appearance of an epistemic gap between the physical and the phenomenal. (shrink)

Most philosophers appear to have ignored the distinction between the broad concept of Virtual Machine Functionalism (VMF) described in Sloman&Chrisley (2003) and the better known version of functionalism referred to there as Atomic State Functionalism (ASF), which is often given as an explanation of what Functionalism is, e.g. in Block (1995). -/- One of the main differences is that ASF encourages talk of supervenience of states and properties, whereas VMF requires supervenience of machines that are arbitrarily complex networks of causally (...) interacting (virtual, but real) processes, possibly operating on different time-scales, examples of which include many different procesess usually running concurrently on a modern computer performing various tasks concerned with handling interfaces to physical devices, managing the file system, dealing with security, providing tools, entertainments, and games, and possibly processing research data. Another example of VMF would be the kind of functionalism involved in a large collection of possibly changing socio-economic structures and processes interacting in a complex community, and yet another is illustrated by the kind of virtual machinery involved in the many levels of visual processing of information about spatial structures, processes, and relationships (including percepts of moving shadows, reflections, highlights, optical-flow patterns and changing affordances) as you walk through a crowded car-park on a sunny day: generating a whole zoo of interacting qualia. (Forget solitary red patches, or experiences thereof.) -/- Perhaps VMF should be re-labelled "Virtual MachinERY Functionalism" because the word 'machinery' more readily suggests something complex with interacting parts. VMF is concerned with virtual machines that are made up of interacting concurrently active (but not necessarily synchronised) chunks of virtual machinery which not only interact with one another and with their physical substrates (which may be partly shared, and also frequently modified by garbage collection, metabolism, or whatever) but can also concurrently interact with and refer to various things in the immediate and remote environment (via sensory/motor channels, and possible future technologies also). I.e. virtual machinery can include mechanisms that create and manipulate semantic content, not only syntactive structures or bit patterns as digital virtual machines do. (shrink)

The introduction to the volume and the overview of the idea of naturalizing the mind.

Naturalism is currently the most vibrantly developing approach to philosophy, with naturalised methodologies being applied across all the philosophical disciplines. One of the areas naturalism has been focussing upon is the mind, traditionally viewed as a topic hard to reconcile with the naturalistic worldview. A number of questions have been pursued in this context. What is the place of the mind in the world? How should we study the mind as a natural phenomenon? What is the significance of cognitive science (...) research for philosophical debates? In this book, philosophical questions about the mind are asked in the context of recent developments in cognitive science, evolutionary theory, psychology, and the project of the naturalisation. Much of the focus is upon what we have learned by studying natural mental mechanisms as well as designing artificial ones. In the case of natural mental mechanisms, this includes consideration of such issues as the significance of deficits in these mechanisms for psychiatry. The significance of the evolutionary context for mental mechanisms as well as questions regarding rationality and wisdom is also explored. Mechanistic and functional models of the mind are used to throw new light on discussions regarding issues of explanation, reduction and the realisation of mental phenomena. Finally, naturalistic approaches are used to look anew at such traditional philosophical issues as the correspondence of mind to world and presuppositions of scientific research. (shrink)

The paper argues that dualism can explain mental causation and solve the exclusion problem. If dualism is combined with the assumption that the psychophysical laws have a special status, it follows that some physical events counterfactually depend on, and are therefore caused by, mental events. Proponents of this account of mental causation can solve the exclusion problem in either of two ways: they can deny that it follows that the physical effect of a mental event is overdetermined by its mental (...) and physical causes, or they can accept that the physical effect is overdetermined but claim that this is unproblematic because the case is sufficiently dissimilar to prototypical cases of overdetermination.

In recent years, philosophers have shown a rapidly increasing interest in the problem of consciousness and it is arguably the central issue in current interdisciplinary discussions about the mind. Any convincing theory of consciousness has to account for the perplexing aspects of human self-consciousness. This paper deals with Ibn Sina’s view on the human self-consciousness with special reference to his well-known “Flying Man” thought experiment. In a brief comparative discussion, we will consider some of the parallels between Ibn Sina’s account (...) of “consciousness of consciousness” and the contemporary “higher-order” theories of consciousness. An important point of divergence between Ibn Sina’s line of argument and Descartes’ method over the problem of self-consciousness will be examined, as well. Further, Thomas Nagel’s famous view on the subjective character of conscious experience will be mentioned and compared with the implications of Ibn Sina’s dictum that “our self-consciousness is identical to our existence”.

This paper discloses and questions two assumptions on happiness that are implied by medical and technological proposals for mood enhancement. The first assumption holds that happiness consists of the indiscriminate maximization of positive and minimization of negative emotions. Second, mood enhancement implies the belief that an effortless enhancement of positive emotions will increase happiness. These assumptions are questioned by investigating the validity of the common sense slogan ‘No pain, no gain’. Support for this claim is found in literature on adversity (...) and happiness, effort and happiness, and in evolutionary psychology. From these research domains it is shown that adversity, pain, bother or effort should not always be regarded as negative experiences to be avoided in the pursuit for happiness. In some cases they can contribute to a person’s quality of life. By questioning the indiscriminate and effortless enhancement of positive emotions and avoidance of negative ones, this perspective suggests a different view on happiness than the one generally assumed by proponents of mood enhancement.

This dissertation aims at forging an archetectonic link between Kant's first and third Critiques within a cognitive-semantic framework. My aim is to show how the major conceptual innovations of Kant’s third Critique can be plausibly understood in terms of the theoretical aims of the first, (Critique of Pure Reason). However, unlike other cognition-oriented approaches to Kant's third Critique, which take the point of contact between the first and third Critique's to be the first Critique's Transcendental Analytic, I link these two (...) works via the first Critique's Transcendental Dialectic, specifically its discussions of the "ideas of pure reason." According to Kant, the “ideas of pure reason” (IPRs) — viz., the notions of self, world-whole, and God — are innate content-bearing entities representing three types of transempirical object, none of which are possible objects of cognition. However, although Kant denies that these rather unique content-bearers can be used for purposes of “speculative cognition,” he does think that they have an internal functional value for human cognitive systems. Although under my analysis of their functional value the IPRs subserve a highest-order aim which derives from theoretical reason — namely, to ground and optimize cognitive systematicity — their directive content in fact renders their implementation(thus their form of intentionality) more characteristic of practical reason. Kant’s positive account of reason’s “interest” in and use of the IPRs exhibits a kind of cognitive pragmatism. Of utmost concern to the cognitive-semantic enterprise, as I conceive it, is the development of (what might be called) a metaphysics of intentionality. A `metaphysics of intentionality', as I use the term, refers to a coherent set of postulative propositional cognitions (or, at any rate, content-bearing entities) implemented, first, for the sake of rationally explaining the phenomenological unity and object-directed character of our perceptual states and, second, to explain why the objects represented in such states are, or must be, law-governed and thus necessarily amenable to scientific investigation. On my view, the discussions in Kant’s third Critique nontrivially contribute to the development of a metaphysics of intentionality and thus to the larger cognitive-semantic enterprise of Kant's first Critique, and it is this link that lends Kant's third Critique a cognitive significance.

A persuasive monograph that answers the keyepistemological arguments against anti-individualism in thephilosophy of mind.

Chalmers (The character of consciousness, 2010) argues for an acquaintance theory of the justification of direct phenomenal beliefs. A central part of this defense is the claim that direct phenomenal beliefs are cognitively significant. I argue against this. Direct phenomenal beliefs are justified within the specious present, and yet the resources available with the present ‘now’ are so impoverished that it barely constrains the content of a direct phenomenal belief. I argue that Chalmers’s account does not have the resources for (...) explaining how direct phenomenal beliefs support the inference from ‘this E is R’ to ‘that was R.’. (shrink)

Over the last three decades, joint action has received various definitions, which for all their differences share many features. However, they cannot fit some perplexing cases of weak joint action, such as demonstrations, where agents rely on distinct epistemic sources and as a result have no first-hand knowledge about each other. I argue that one major reason why the definition of such collective actions is akin to the classical ones, is because it crucially relies on the concept of common knowledge. (...) To this end, I first argue for the necessity of common knowledge for joint action in general due to the increased reliability of success it entails. I then defend the relevance of common knowledge against several criticisms, point at an adequate weakening, and discuss alternative approaches. Although structurally weaker, this common knowledge has a richer content in weak joint actions. As a result, even if the links between individuals are seriously stretched, much is still shared among them. Weak joint actions still require considerable cognitive abilities indeed. (shrink)

Perhaps we fail to understand the mimetic nature of desire because we rarely refer to the first stages of human development. Every child has appetites, instincts and a given cultural milieu in which he learns by imitating adults or peers. Imitation and learning are inseparable. It may be said that we acquire knowledge by using our minds; but the child absorbs knowledge directly into his psychic life. . . . Impressions do not merely enter his mind; they form it. They (...) incarnate themselves in him. . . . We have named this type of mentality, The Absorbent Mind. The Montessori Method of early childhood education offers mimetic theory an avenue to explore healthy patterns of desire in children. Such an .. (shrink)

Traditionally, Hume's account of memory is considered an individualist-atomic representational theory. However, textual evidence suggests that Hume's account is better seen as a first attempt to create a social theory of memory that considers social context, custom and habits, language, and logical structures as constitutive elements of memory.

Qu'est-ce qu'un concept ? Cette question concerne au premier chef ceux qui ont fait du concept une profession : chercheurs dans les diverses sciences, humaines ou non, et travailleurs intellectuels en général. Plus largement, elle exprime cette curiosité naturelle, non dénuée d'inquiétude, à laquelle toute pensée, commune ou savante, semble exposée et qui nous pousse à souhaiter, sans savoir sans doute exactement ce que nous recherchons par là, une détermination plus exacte de ce que nous entendons par « pensée ». (...) Que veut dire pour la pensée que celle-ci, en un certain sens, passe par la mise en œuvre de ce que nous appelons « concepts » ? Quelle est la nature exacte de cette discrimination faite alors entre le conceptuel et le non-conceptuel ? Les concepts, étymologiquement, sont censés nous ménager une prise sur quelque chose. Cette chose, est-ce bien la réalité même ? Sommes-nous ainsi capables de penser « les choses telles qu'elles sont » ? Et, si c'est le cas, à quel prix ? Quelles limites faut-il accepter à l'efficacité de nos pensées ? Telles sont les questions recouvertes par leur caractérisation en termes de « concepts », et celles que ce livre, au fil des exemples et mises en situation, s'attache à résoudre. (shrink)

According to the standard view, the causal process connecting a past representation and its subsequent recall involves intermediary memory traces. Yet Bertrand Russell and Ludwig Wittgenstein held that since the physiological evidence for memory traces isn't quite conclusive, it is prudent to come up with an account of memory causation-referred to as nmemic causation—that manages without the stipulation of memory traces. Given mnemic causation, a past representation is directly causally active over a temporal distance. I argue that the stipulation of (...) memory traces is indeed indispensable for analyzing mernory causation. (shrink)

The concept of memory rests at the heart of Bersgon’s theory of consciousness. His theory of memory is the novelty in the history of philosophy. It is not an affirmation either of the metaphysical conceptions (versions à la Platonism) where “all knowledge is recollection”, nor of empiricist psychology possibly traceble back to Aristotle, where, briefly speaking, the faculty of memory depends on the general perceptual capacity. Contrary to the majority of the philosophical and psychological theories of his epoch, Bergson assigns (...) memory the most important role in the intellectual process, denying the characteristic of passivity (from greek word pathos meaning kind of affection) attached to it, instead concerning with the creative, productive and vital power of memory rather than merely its retentive and recalling capacity.

L’arte della memoria è uno degli archetipi della cultura occidentale fin dall’antica Grecia: è stato Platone ad ‘inventare’ l’immagine dell’anima come blocco di cera, su cui le sensazioni si imprimono come segni di sigilli; ed è stato poi Aristotele a riprendere in parte questo modello, arricchendolo però di temi fondamentali. Ma anche in epoche successive l’arte della memoria ha svolto una funzione fondamentale intrecciandosi a temi sia epistemologici che di schietta natura metafisica. Questo volume, frutto di un seminario tenuto alla (...) Scuola Normale nel settembre 2006, intende ripercorrere alcune delle principali stazioni della riflessione sulla memoria fra antichità e mondo moderno chiedendosi se, e in quale misura, questa relativa continuità di approccio si debba ad un consapevole attingere alla tradizione platonica e aristotelica; se, e in quale misura, elementi comuni o varianti del modello iniziale siano riportabili alle metafore adottate, sin da subito, per la descrizione dei processi mentali – riconducibili in ogni caso all’idea comune di ‘tracce’ che la sensazione imprime nell’anima.

The nature of perceptual demonstratives, the ‘that F’ component of judgments of the form ‘that F is G’ based on perceptual input, has been a topic of interest for many philosophers. Another related, though distinct, question concerns the nature of demonstrative judgments based not on current perceptual input, but instead derived from memory. I argue that the account put forward by John Campbell fails to adequately account for memory-based demonstrative thought.

In this paper, I discuss Noë’s enactive account of our perceptual encounter with the intrinsic properties of the surrounding objects. First, I argue that this view falls into a dilemma in which either we are left without a satisfactory explanation of this encounter or, in order to keep Noë’s view, we must abandon our ordinary intuitions about the ontological status of the intrinsic properties of objects. Then, I show that, strikingly, there is a suggestive unofficial strand running in Noë that (...) avoids this dilemma. Finally, I argue this unofficial thread leads to a view about the perspectival character of perceptual experience and the place of sensorimotor understanding in perceptual content that is to be preferred over Noë’s official view about these issues.

Current orthodoxy in the philosophy of perception views indirect realism as misguided, wrongheaded or simply outdated. The reasons for its pariah status are variegated. Although it is surely not unreasonable to speculate that philosophical fashion is one factor that contributes to this situation, there are also solid philosophical arguments which put pressure on the indirect realist position. In this paper, I will discuss one such main objection and show how the indirect realist can face it. The upshot will be a (...) defence of a new structural account of indirect realism which is immune to a number of objections that have been traditionally levelled at such theories of perceptual consciousness.

Epistemic modal predicate logic raises conceptual problems not faced in the case of alethic modal predicate logic: Frege’s “Hesperus-Phosphorus” problem—how to make sense of ascribing to agents ignorance of necessarily true identity statements—and the related “Hintikka-Kripke” problem—how to set up a logical system combining epistemic and alethic modalities, as well as others problems, such as Quine’s “Double Vision” problem and problems of self-knowledge. In this paper, we lay out a philosophical approach to epistemic predicate logic, implemented formally in Melvin Fitting’s (...) First-Order Intensional Logic, that we argue solves these and other conceptual problems. Topics covered include: Quine on the “collapse” of modal distinctions; the rigidity of names; belief reports and unarticulated constituents; epistemic roles; counterfactual attitudes; representational vs. interpretational semantics; ignorance of co-reference vs. ignorance of identity; two-dimensional epistemic models; quantification into epistemic contexts; and an approach to multi-agent epistemic logic based on centered worlds and hybrid logic.

In this chapter I consider various potential challenges to free will from the modern mind sciences. After motivating the importance of considering these challenges, I outline the argument structure for such challenges: they require simultaneously establishing a particular condition for free will and an empirical challenge to that condition. I consider several potential challenges: determinism, naturalism, and epiphenomenalism, and explain why none of these philosophical challenges is bolstered by new discoveries from neuroscience and psychology. I then respond to relevant empirical (...) challenges to the role of consciousness and rationality in action. (shrink)

Political candidates often believe they must focus their campaign efforts on a small number of swing voters open for ideological change. Based on the wisdom of opinion polls, this might seem like a good idea. But do most voters really hold their political attitudes so firmly that they are unreceptive to persuasion? We tested this premise during the most recent general election in Sweden, in which a left- and a right-wing coalition were locked in a close race. We asked our (...) participants to state their voter intention, and presented them with a political survey of wedge issues between the two coalitions. Using a sleight-of-hand we then altered their replies to place them in the opposite political camp, and invited them to reason about their attitudes on the manipulated issues. Finally, we summarized their survey score, and asked for their voter intention again. The results showed that no more than 22% of the manipulated replies were detected, and that a full 92% of the participants accepted and endorsed our altered political survey score. Furthermore, the final voter intention question indicated that as many as 48% (69.2%) were willing to consider a left-right coalition shift. This can be contrasted with the established polls tracking the Swedish election, which registered maximally 10% voters open for a swing. Our results indicate that political attitudes and partisan divisions can be far more flexible than what is assumed by the polls, and that people can reason about the factual issues of the campaign with considerable openness to change.

In Foundations for Moral Relativism, J. David Velleman shows that different communities can indeed be subject to incompatible moralities, because their local mores are rationally binding. At the same time, he explains why the mores of different communities, even when incompatible, are still variations on the same moral themes. The book thus maps out a universe of many moral worlds without, as Velleman puts it, "moral black holes”. The five self-standing chapters discuss such diverse topics as online avatars and virtual (...) worlds, lying in Russian and truth-telling in Quechua, the pleasure of solitude and the fear of absurdity. Accessibly written, Foundations for Moral Relativism presupposes no prior training in philosophy. (shrink)

Every day, thousands of polls, surveys, and rating scales are employed to elicit the attitudes of humankind. Given the ubiquitous use of these instruments, it seems we ought to have firm answers to what is measured by them, but unfortunately we do not. To help remedy this situation, we present a novel approach to investigate the nature of attitudes. We created a self-transforming paper survey of moral opinions, covering both foundational principles, and current dilemmas hotly debated in the media. This (...) survey used a magic trick to expose participants to a reversal of their previously stated attitudes, allowing us to record whether they were prepared to endorse and argue for the opposite view of what they had stated only moments ago. The result showed that the majority of the reversals remained undetected, and a full 69% of the participants failed to detect at least one of two changes. In addition, participants often constructed coherent and unequivocal arguments supporting the opposite of their original position. These results suggest a dramatic potential for flexibility in our moral attitudes, and indicates a clear role for self-attribution and post-hoc rationalization in attitude formation and change.

Externalism holds that the content of our utterances and thoughts are determined partly by the environment. Here, I offer an argument which suggests that externalism is incompatible with a natural view about ontological commitment--namely, the Quinean view that such commitments are fixed by the range of the variables in your theory. The idea in brief is that if Oscar mistakenly believes that water = XYZ, the externalist ontologically commits Oscar to two waterish kinds, whereas the Quinean commits him to one (...) such kind (albeit a metaphysically impossible kind). The penultimate section addresses a variety of objections to the argument. (shrink)

This paper explores the question concerning the relationship between basic and higher layers of experience and self-experience. The latter distinction implicitly presupposes the idea of a univocal foundation. After explaining the formal ontological law of foundation, an attempt is made to clarify how the idea of foundation may be suitable to understand the relationship among moments, or layers, of self-experience. To this aim, the phenomenological descriptions of self- and world-experience in dementia and schizophrenia are compared. The comparison between these two, (...) in many ways radically different, pathologies allows us to highlight both the potentialities and the limits of resorting to the foundational relationship for the description of lived experience. Taking the challenges coming from the description of dementia and schizophrenia into serious consideration, the meaning of the “stratified” account of self-experience will be eventually reassessed, and a way to complement the idea of foundation among layers will be proposed.

The “brain in a vat” thought experiment is presented and refuted by appeal to the intuitiveness of what the author informally calls “the eye for an eye principle”, namely: Conscious mental states typically involved in sensory processes can conceivably successfully be brought about by direct stimulation of the brain, and in all such cases the utilized stimulus field will be in the relevant sense equivalent to the actual PNS or part of it thereof. In the second section, four classic problems (...) of Functionalism are given novel solutions based on the inclusion of peripheral nervous processes as constituents of mental states: The mad pain problem, the problem of pseudo-normal vision, the China-brain problem, and the triviality problem.

A natural way of understanding (non-epistemic) looks talk in natural language is phenomenalist: to ascribe looks to objects is to say something about the way they strike us when we look at them. This explains why the truth values of looks-sentences intuitively vary with the circumstances with respect to which they are evaluated. But Mike Martin (2010) argues that there is no semantic reason to prefer a phenomenalist understanding of looks to “Parsimony”, the position according to which looks are basic (...) visible properties. He suggests a semantics for looks-sentences that explains their intuitive truth values and is compatible with Parsimony. I argue that there is semantic reason to prefer a phenomenalist understanding of looks to a parsimonious one since there is a simpler semantics compatible with a phenomenalist understanding of looks, but not with Parsimony. This semantics provides a better explanation of the relevant truth value distribution. (shrink)

In his 1982 book Wittgenstein On Rules and Private Language, Saul Kripke maintains that Wittgenstein´s rule following considerations land us with a skeptical argument about meaning. This essay contains a short exposition of Kripke´s argument. In addition, I hold, both on textual grounds and by an appeal to some select secondary literature, that Wittgenstein offered no such skeptical argument in the Philosophical Investigations . Although Wittgenstein certainly repudiates a view of meaning based on temporally located mental states, it does not (...) follow that there can be no meaning-grounding facts of other sorts. Although it is true that mental states, viewed atomistically, offer no sure foundation for meaning, I argue that it need not follow, pace Kripke, that no facts about an individual´s past mental life can ever make it clear that he meant ‘plus’ rather than ‘quus’ while performing any addition. For the individual´s past mental life is indeed relevant to meaning when considered in its unfolding in time. The essay further contains explorations on the very nature of the practice of following a rule and ends with a discussion of the solitary rule follower. (shrink)

In his The Phenomenon of Man, Pierre Teilhard de Chardin develops concepts of consciousness, the noosphere, and psychosocial evolution.

Teilhard’s work can be seen as advancing this psychological lineage or psychogenesis. That is, the evolutionary emergence of matter in increasing complexity from sub-atomic particles to the human brain and (...) reflective consciousness leads to a noosphere evolving towards an Omega point. Teilhard’s central ideas provide intimations of a numinous principle implicit in cosmology and the discovery that in and through humanity evolution not only becomes conscious of itself but also directed and purposive.

How are we to understand the intentionality of mental acts which lack existing objects? Two alternatives present themselves: the Meinongian, which would involve the postulation of special nonexistent objects; and the adverbial, which would appeal instead to special qualities of the acts themselves. The present paper, which draws on the hitherto neglected aesthetic writings of the Meinong school, is concerned with certain psychological and aesthetic implications of the adverbial approach. The 'substitution theory' of the title consists in the view that (...) our experience of works of art can best be conceived in terms of special sorts of'modified' psychic phenomena which may be said to substitute or stand proxy for our normal emotional experiences. The job of the work of art, on this view, is precisely to bring about such proxy emotions within the psychic subject. This idea is shown to have imphcations for the treatment of aesthetic pleasure, as also for our understanding of the nature of artistic traditions and of the value of works of art. (shrink)

The paper articulates a puzzle that consists in the prima facie incompatibility between three widely accepted theses. The first thesis is, roughly, that there are intrinsically self-representational thoughts. The second thesis is, roughly, that there is a particular causal constraint on mental representation.

Finally, a number of solution strategies are considered, (...) and a preliminary diagnosis is provided. (shrink)

Crispin Wright argues that John McDowell’s use of disjunctivism to respond to the sceptic misses the point of the sceptic’s argument, for disjunctivism is a thesis about the differing metaphysical natures of veridical and nonveridical experiences, whereas the sceptic’s point is that our beliefs are unjustified because veridical and nonveridical experiences can be phenomenally indistinguishable. In this paper, I argue that McDowell is responsive to the sceptic’s focus on phenomenology, for the point of McDowell’s response is that it is the (...) phenomenal character of experience that makes the belief in disjunctivism rational, and thereby also makes rational the anti-sceptical belief that, other things being equal, the world is the way it appears.

An overview of the philosophy and psychology of hallucination and its relevance to the philosophy of perception.

Is there a space of the sensory modalities? Such a space would be one in which we can represent all the actual, and at least some of the possible, sensory modalities. The relative position of the senses in this space would indicate how similar and how different the senses were from each other. The construction of such a space might reveal unconsidered features of the actual and possible senses, help us to define what a sense is, and provide grounds that (...) we might use to decide what is one token sense rather than multiple token senses. -/- In this paper, I explore, refine, and defend the idea that we can construct such a space—an idea that I briefly proposed in earlier work (Macpherson 2011a and 2011b). In doing so, I defend the idea from an objection that Richard Gray (2012) has voiced. Gray claims that the dimensions of the space of sensory modalities must generate a non-­‐arbitrary ordering of the senses. He argues that we cannot find dimensions that do so. I disagree. I identify different ways in which a space could be arbitrary but I argue that we can define a space of the sensory modalities in a non-arbitrary manner. I give examples of what the dimensions might be. (shrink)

Husserl's phenomenology of the body constantly faces issues of demarcation: between phenomenology and ontology, soul and spirit, consciousness and brain, conditionality and causality. It also shows that Husserl was eager to cross the borders of transcendental phenomenology when the phenomena under investigation made it necessary. Considering the details of his description of bodily sensations and bodily behaviour from a Merleau-Pontian perspective allows one also to realise how Husserl (unlike Heidegger) fruitfully explores a phenomenological field located between a science of pure (...) consciousness and the natural sciences. A phenomenological discussion of naturalism thus cannot limit itself to the task of discrimination, it must attempt to integrate what an eidetic analysis has separated: inside and outside, here and there, first-person and third-person perspective, motivation and causality. Husserl's phenomenology of the body thus shows that dualism is at best a methodological but never an ontological option for the mind-body problem. (shrink)

What is the proper unit of analysis in the psycholinguistics of dialog? While classical approaches are largely based on models of individual linguistic processing, recent advances stress the social coordinative nature of dialog. In the influential interactive alignment model, dialogue is thus approached as the progressive entrainment of interlocutors' linguistic behaviors toward the alignment of situation models. Still, the driving mechanisms are attributed to individual cognition in the form of automatic structural priming. Challenging these ideas, we outline a dynamical framework (...) for studying dialog based on the notion of interpersonal synergy. Crucial to this synergetic model is the emphasis on dialog as an emergent, self-organizing, interpersonal system capable of functional coordination. A consequence of this model is that linguistic processes cannot be reduced to the workings of individual cognitive systems but must be approached also at the interpersonal level. From the synergy model follows a number of new predictions: beyond simple synchrony, good dialog affords complementary dynamics, constrained by contextual sensitivity and functional specificity. We substantiate our arguments by reference to recent empirical studies supporting the idea of dialog as interpersonal synergy. (shrink)

Epistemological disjunctivism in outline -- Favouring versus discriminating epistemic support -- Radical scepticsim.

This paper considers two accounts of the way that colours are represented in perception, thought, and language that are consistent with relationalist theories of colour: Jonathan Cohen’s contextualist semantics for colour ascriptions, and Andy Egan’s suggestion that colour ascriptions have self-locating contents. I argue that colours are not represented in perception, thought, or language as mind-dependent relational properties.

John McDowell and Christine Korsgaard have defended the claim that when human beings judge or believe that p, they are exercising a fundamental kind of freedom, the “freedom of judging.” David Owens has challenged the view: he argues that they offer us at best no more than a modest notion of freedom, which does not vindicate the claim that we are free in many relevant instances of judgment, in particular in perceptual judgment. I argue that Owens is right if we (...) view the freedom of judgment along the lines of McDowell’s and Korsgaard’s proposals – as being a form of freedom which is describable as “freedom of choosing between alternatives,” but that that is not the only option available. In order to secure the nexus between reason and freedom, we can exploit a quite distinct model of freedom, which is the “freedom of autonomy.”. (shrink)

For the purpose of this paper, I take it for granted that subjectivity is an essential character of perceptual experience. What I take issue with is the further claim that subjectivity of experience tends to support the view that phenomenal characters are intrinsic properties of experience. A criticism of the claim can be presented from the perspective of representationalism according to which phenomenal character is a kind of representational character. But representationalism fails to do justice to the fact that from (...) the subjective point of view, we seem to be directly aware of mind-independent objects in the world. A stronger criticism canbe based on the disjunctivist’s view of experience that best accommodates direct awareness of the external world. But disjunctivism rejects the common kind that also seems from the subject’s point of view to be shared by veridical perception and hallucination. The crucial problem is whether disjunctivists can make sense of the phenomenology of hallucination. Focusing the discussion on Martin’s epistemic version of disjunctivism, I hope to show the relevance of solving this problem for a better understanding of the subjectivity of experience. (shrink)

Disjunctivism in philosophy of perception maintains that whereas veridical perceptions are relational states involving objects of the external world, illusions and hallucinations are non-relational states of the subjects. Veridical and non veridical perceptions could be subjectively indistinguishable, but this fact would not be able to support fundamental psychological explanations. Disjunctivism has to face some important problems. The aim of this paper is to explore a peculiar elaboration of disjunctivism able to face them. Our proposal intends to be substantive, offering a (...) counterfactual explanation of the differences between veridicaland non veridical perceptions. We will arrive to an a posteriori disjunctivism for some relevant types of perceptual experiences. The a posteriori character of our position will be consequent with the external nature of the intentional objects of veridical perceptions. But our disjunctivism will be concerned only with types of perceptual experiences. That way, it could make room for many sorts of internalist psychological explanations in the context of a general disjunctivist approach. (shrink)
