A cornerstone of Sartre’s philosophy, _The Imaginary_ was first published in 1940. Sartre had become acquainted with the philosophy of Edmund Husserl in Berlin and was fascinated by his idea of the 'intentionality of consciousness' as a key to the puzzle of existence. Against this background, _The Imaginary_ crystallized Sartre's worldview and artistic vision. The book is an extended examination of the concepts of nothingness and freedom, both of which are derived from the ability of consciousness to imagine objects both (...) as they are and as they are not – ideas that would drive Sartre's existentialism and entire theory of human freedom.

How do rational minds make contact with the world? The empiricist tradition sees a gap between mind and world, and takes sensory experience, fallible as it is, to provide our only bridge across that gap. In its crudest form, for example, the traditional idea is that our minds consult an inner realm of sensory experience, which provides us with evidence about the nature of external reality. Notoriously, however, it turns out to be far from clear that there is any viable (...) conception of experience which allows it to do the job. The original problem is to show that thought is rationally constrained by external reality. If sensory experience is to provide the solution--in particular, if it is to provide the answer to sceptical challenges--it must therefore meet two criteria. First, it must itself be `receptive'--i.e., appropriately constrained by external reality. Second, it must be the kind of thing that can enter into a logical or rational relationship with belief--it must already be `conceptual,' in other words. In arguing against the idea that anything could serve both roles, Wilfred Sellars termed this conception of experience "the Myth of the Given.". (shrink)

My primary aim in this article is to provide a philosophical account of the unity of hallucinations, which can capture both perceptual hallucinations (which are subjectively indistinguishable from perceptions) and non-perceptual hallucinations (all others). Besides, I also mean to clarify further the division of labour and the nature of the collaboration between philosophy and the cognitive sciences. Assuming that the epistemic conception of hallucinations put forward by M. G. F. Martin and others is largely on the right track, I will (...) focus on two main tasks: (a) to provide a satisfactory phenomenology of the subjective character of perceptions and perceptual hallucinations and (b) to redress the philosophers’ neglect of non-perceptual hallucinations. More specifically, I intend to apply one of the central tenets of the epistemic conception—that hallucinations can and should be positively characterised in terms of their phenomenological connections to perceptions—to non-perceptual hallucinations as well. That is, I will try to show that we can positively specify the class of non-perceptual hallucinations by reference to the distinctive ways in which we first-personally experience them and perceptions in consciousness. The task of saying more about their underlying third-personal nature may then be left to the cognitive sciences. (shrink)

One central fact about hallucinations is that they may be subjectively indistinguishable from perceptions. Indeed, it has been argued that the hallucinatory experiences concerned cannot— and need not—be characterized in any more positive general terms. This epistemic conception of hallucinations has been advocated as the best choice for proponents of experiential (or “naive realist”) disjunctivism—the view that perceptions and hallucinations differ essentially in their introspectible subjective characters. In this chapter, I aim to formulate and defend an intentional alternative to experiential (...) disjunctivism called experiential intentionalism. This view not only enjoys some advantages over its rival but is also compatible with the epistemic conception of hallucinations, as well as with the disjunctivist view that perceptions and hallucinations differ essentially in their third-personal structures (e.g., their causal, informational, or reason-providing links to reality). It also maintains that there are actually two aspects to the subjective indistinguishability of mental episodes: (i) we cannot distinguish their first-personal characters in introspective awareness; and (ii) we cannot distinguish their third-personal structures in experiential awareness—that is, in how they are given to consciousness. While experiential disjunctivism makes the mistake of ignoring (ii) and reducing subjective indiscriminability to (i), experiential intentionalism correctly identifies (ii) as the primary source of the subjective indistinguishability of perception-like hallucinations. Accordingly, the intentional error involved in such hallucinations is due to the fact that we consciously experience them as possessing a relational structure. (shrink)

A number of philosophers have argued in favour of the Dependency Thesis: if a subject sensorily imagines an F then he or she sensorily imagines from the inside perceptually experiencing an F in the imaginary world. They claim that it explains certain important features of imaginative experience, in brief: the fact that it is perspectival, the fact that it does not involve presentation of sensory qualities and the fact that mental images can serve a number of different imaginings. I argue (...) that the Dependency Thesis is false and that, in any event, it does not have the explanatory credentials claimed for it. Some of the features of imaginative experience are incorrectly specified, namely the absence of presentation of sensory qualities. With a more precise idea of what we need to explain, I argue that the explanation should proceed by noting that imagination and perception have phenomenally similar contents and that this is to be explained in terms of the similar kinds of representations in play. I trace the consequences of my discussion for disjunctivist theories of perception, Berkeleian Idealism and the characterisation of knowing what an experience is like. (shrink)

Book description: The capacity to represent and think about time is one of the most fundamental and least understood aspects of human cognition and consciousness. This book throws new light on central issues in the study of the mind by uniting, for the first time, psychological and philosophical approaches dealing with the connection between temporal representation and memory. Fifteen specially written essays by leading psychologists and philosophers investigate the way in which time is represented in memory, and the role memory (...) plays in our ability to reason about time. They offer insights into current theories of memory processes and of the mechanisms and cognitive abilities underlying temporal judgements, and draw out fundamental issues concerning the phenomenology and epistemology of memory and our understanding of time. The chapters are arranged into four sections, each focused on one area of current research: Keeping Track of Time, and Temporal Representation; Memory, Awareness and the Past; Memory and Experience; Knowledge and the Past: The Epistemology and Metaphysics of Time. A general introduction gives an overview of the topics discussed and makes explicit central themes which unify the different philosophical and psychological approaches. (shrink)

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

The disjunctive theory of perception claims that we should understand statements about how things appear to a perceiver to be equivalent to statements of a disjunction that either one is perceiving such and such or one is suffering an illusion (or hallucination); and that such statements are not to be viewed as introducing a report of a distinctive mental event or state common to these various disjoint situations. When Michael Hinton first introduced the idea, he suggested that the burden of (...) proof or disproof lay with his opponent, that what was needed was to show that our talk of how things look or appear to one..

I argue that the transparency of experience provides the basis of arguments both for intentionalism -- understood as the view that there is a necessary connection between perceptual content and perceptual phenomenology -- and for the view that the contents of perceptual experiences are Russellian propositions. While each of these views is popular, there are apparent tensions between them, and some have thought that their combination is unstable. In the second half of the paper, I respond to these worries by (...) arguing that Russellianism is consistent with intentionalism, that their conjunction is consistent with both internalism about phenomenology and externalism about perceptual content, and that the resulting view receives independent support from the relationship between hallucination and thought.

This book is based on the William James Lectures delivered at Harvard University in 1982. It offers a new approach to the philosophical understanding of a person, taking as fundamental the process of living as a person, and emphasising the continuity and development across time of an individual life.

Brian O'Shaughnessy puts forward a bold and original theory of consciousness, one of the most fascinating but puzzling aspects of human existence. He analyses consciousness into purely psychological constituents, according pre-eminence to its epistemological power; the result is an integrated picture of the conscious mind in its natural physical setting. Consciousness and the World is a rich and exciting book, a major contribution to our understanding of the mind.

This essay is a long one. It is not meant to be read in a single sitting. Its structure is as follows. In section I, I explicate perceptual anti-individualism. Section II centers on the two aspects of the representational content of perceptual states. Sections III and IV concern the nature of the empirical psychology of vision, and its bearing on the individuation of perceptual states. Section V shows how what is known from empirical psychology undermines disjunctivism and hence certain further (...) views that entail it, including naive realism. In Section VI, I raise a further point against disjunctivism. Section VII indicates how general reflection on perceptual perspective and epistemic ability supports the constraints from empirical psychology. It also explains how reflection on veridicality conditions, psychological explanation, and cognitive ability conspire to force recognition of the two kinds of representation mentioned in the preceding paragraph. In the Appendix, I criticize attempts to support disjunctivism. (shrink)

How do pictures represent? In this book Robert Hopkins casts new light on an ancient question by connecting it to issues in the philosophies of mind and perception. He starts by describing several striking features of picturing that demand explanation. These features strongly suggest that our experience of pictures is central to the way they represent, and Hopkins characterizes that experience as one of resemblance in a particular respect. He deals convincingly with the objections traditionally assumed to be fatal to (...) resemblance views, and shows how his own account is uniquely well placed to explain picturing's key features. His discussion engages in detail with issues concerning perception in general, including how to describe phenomena that have long puzzled philosophers and psychologists, and the book concludes with an attempt to see what a proper understanding of picturing can tell us about that deeply mysterious phenomenon, the visual imagination. (shrink)

Robert Hopkins’s Picture, Image and Experience aims to provide an account of pictorial representation that vindicates the intuitions of the many, namely that pictorial representation is a deeply visual phenomenon, that an explanation of pictorial representation needs to be based on an explanation of our experience of pictures, and that there must be some sense in the idea that pictures resemble their objects. Hopkins proposes that we can show what is correct in these intuitions by explaining pictures as representations that (...) depend on a distinctive sort of perceptual experience: experienced resemblance in outline shape between a picture and its object. Experienced resemblance in outline shape is the experience of sameness of the solid angle subtended by the contours on the pictorial surface and the solid angle subtended by the actual depicted objects. Pictures don’t resemble their objects but they are experienced as such and it is sameness of outline shape or sameness of subtended solid angles that secures this experience. (shrink)

Necessarily and trivially, ‘I’ means its occurrent utterer or thinker. But how is self-reference possible? Providing an adequate answer to this very hard question is the task undertaken by John Campbell in Past, Space, and Self. His answer, in a nutshell, is that the fundamental ground of self-reference is self-consciousness; and the bulk of the book is devoted to sketching the architecture of this cognitive capacity. Campbell wants to say that the essence of self-consciousness is given in the set of (...) cognitive abilities making it possible to think of oneself as presented and individuated by means of a causal-spatiotemporal self-narrative. Not only is self-consciousness the ground of self-reference, however, but also “possession of this core set of abilities defines possession of concepts”. While Campbell thinks of his account as making up a seamless whole, I would like to distinguish for the purposes of exposition between the thesis that self-consciousness in his sense explains self-reference and the thesis that Campbellian self-consciousness explains concept-possession. It may be that the case made for one of the theses is stronger and more convincing than the case made for the other; I shall address that issue briefly later. (shrink)
