I develop a seeming antinomy in relation to the question, Do natural kind properties, strictly speaking, characterize the phenomenology of experience? Or, in Peacockean terms, Are natural kind concepts observational? On the one hand, naïve descriptions of experience are rich descriptions, often characterizing our experience in terms of the presence of natural kinds. Thus, negative answers to such questions falsify how our experience seems to us. On the other hand, attributing rich contents to experience forces us to treat certain matching (...) experiences as illusions or, in Peacockean terms, purely perceptual errors. In both cases this is an implausible application of these notions, for, in such cases, all the properties seemingly being picked up on by the visual system are instantiated. The intractability of this apparent antinomy motivates a contextualist resolution: How rich a description it is appropriate to give of a stretch of someone’s experiential life depends on the context we are in.

Philosophers have lately seized upon Sperling’s partial report technique and subsequent work on iconic memory in support of controversial claims about perceptual experience, in particular that phenomenology overflows cognitive access. Drawing on mounting evidence concerning postdictive perception, I offer an interpretation of Sperling’s data in terms of cue-sensitive experience which fails to support any such claims. Arguments for overflow based on change-detection paradigms (e.g., Landman et al., 2003; Sligte et al., 2008) cannot be blocked in this way. However, such paradigms (...) are fundamentally different from Sperling’s and, for rather different reasons, equally fail to establish controversial claims about perceptual experience. (shrink)

Tradition has it that, although we experience darkness, we can neither hear nor hallucinate silence. At most, we hear that it is silent, in virtue of lacking auditory experience. This cognitive view is at odds with our ordinary thought and talk. Yet it is not easy to vouchsafe the perception of silence: Sorensen‘s recent account entails the implausible claim that the permanently and profoundly deaf are perpetually hallucinating silence. To better defend the view that we can genuinely hear and hallucinate (...) silence, we must reject the austere picture of conscious experience which underpins the cognitive theory. According to that picture, conscious experience is a simple relation between subjects and objects. In the absence of an object, there is no relation, and so no experience. By enriching this picture, room can be found for the experience of silence. I explore this idea in two phases. First, I defend the thought that we can hear and hallucinate certain forms of silence, such as pauses, in virtue of experiencing contrastive sounds. Second, I draw on Moore‘s analysis of sensation to suggest that simply experiencing silence is a special form of objectless consciousness. I offer two ways of fleshing out this idea. According to the first, auditory experience possesses a temporal field within which the absence of sounds can be perceived. According to the second, purely Moorean account, it is our capacity to listen in the absence of sounds that underlies the phenomenon of experiencing silence. (shrink)

Orthodox interpretations of Sperling‘s partial report paradigm support the idea that there is substantially more in our streams of consciousness than we can attend to or recall. I propose an alternative, postdictive interpretation which fails to support any such conclusion. This account is defended at greater length in my ‗Perception and iconic memory‘. Here I focus on the role ascribed to attention by the rival interpretations. I argue that orthodox accounts fail to assign a plausible role to attention. In contrast, (...) I suggest a novel way in which heterodox, postdictive account can assign attention a plausible role. We should therefore prefer such accounts over their orthodox rivals. Consequently, Sperling‘s paradigm fails to probe the true extent of conscious awareness unfettered by limitations on attention or memory. (shrink)

Philosophers have long struggled to understand our perceptual experience of temporal properties such as succession, persistence and change. Indeed, strikingly, a number have felt compelled to deny that we enjoy such experience. Philosophical puzzlement arises as a consequence of assuming that, if one experiences succession or temporal structure at all, then one experiences it at a moment. The two leading types of theory of temporal awareness—specious present theories and memory theories—are best understood as attempts to explain how temporal awareness is (...) possible within the constraints of this principle. I argue that the principle is false. Neither theory of temporal awareness can be made workable unless it is rejected. Our experience of temporal phenomena cannot be understood if we attempt to break experience down into instantaneous slices. In order to understand the perception of temporal properties we must look beyond the instant. (shrink)

A Martian reading contemporary work on perception might be forgiven for thinking that humans had only one sense: vision. Witness the title of one popular recent collection: Vision and mind: selected readings in the philosophy of perception. Our obsession with sight is stifling. It leads to distorted vision-based models of the other senses, and it means that the distinctive puzzles raised by non-visual modalities are routinely neglected. With this pioneering and long-overdue collection of essays on auditory perception, Nudds and O’Callaghan (...) aim to start correcting this state of affairs. They deserve much praise, not least for their own substantial contributions and splendid introduction. (shrink)

We are no less directly acquainted with the temporal structure of the world than with its spatial structure. We hear one word succeeding another; feel two taps as simultaneous; or see the glow of a firework persisting, before it finally fizzles and fades. However, time is special, for we not only experience temporal properties; experience itself is structured in time. -/- Part One articulates a natural framework for thinking about experience in time. I claim (i) that experience in its experiential (...) aspect has a realistically conceived temporal structure; (ii) that our judgements about that structure always go via judgements about the temporal structure of the apparent objects of perception; and (iii) that a subject undergoing perceptual experience of a given experiential kind is always in a position to know that they are undergoing experience of that kind simply in virtue of so undergoing. On this basis, I argue that the temporal structure of experience cannot systematically come apart from the temporal structure of its objects. -/- Part Two treats four puzzles relating to our experience of time. The first is Dennett’s notorious discussion of masking and apparent motion phenomena. The second is the traditional debate regarding the very possibility of perceiving temporal properties. The third is Fara’s recent contention that standard explanations of our experience of slow changes preclude us from perceiving constant motion. A common reaction to these three puzzles is to reject some element of the naïve picture of temporal experience developed in Part One. I resolve them instead by showing how each arises from mistakenly thinking that experience is homoeomerous down to very short durations or instants. That is, thinking that we can analyse experience into a series of independent short slices, and explain the nature of the stream of consciousness in terms of those slices. The final chapter discusses a fourth puzzle about visual motion perception which I diagnose as driven by a rather different, but equally misguided way of thinking about vision. (shrink)

Olson (2009) argues that time does not pass because (i) if it did it would have to pass at some rate, and (ii) there is no rate at which it could pass. This paper exposes a confusion about the nature of rates upon which this argument rests.

Sidney Morgenbesser brought to attention cases of the following form: (MC1) Chump tosses an indeterministic coin and, whilst it is in mid-air, calls heads. The coin lands tails, and Chump loses. His betting was causally independent of the coin’s fall. Chump seems right to say: ‘If I had bet tails, I would have won.’1 (MC2).

Yagisawa (2005) considers two old arguments against the existence requirement. Both arguments are significantly less appealing than Yagisawa suggests. In particular, the second argument, first given by Kaplan (1989: 498), simply assumes that existence is contingent (§1). Yagisawa’s ‘new’ argument shares this weakness. It also faces a dilemma. Yagisawa must either treat ‘at @’ as a sentential operator occupying the same grammatical position as ‘∼’ or as supplying an extra argument place. In the former case, Yagisawa’s argument faces precisely the (...) problems he concedes that Kaplan’s argument does (§2). In the latter case, though the argument does not face these problems, it renders the sense in which things exist contingently no threat to (E) properly understood (§3). (shrink)

Strong or Pure Intentionalism is the claim that the phenomenal character of any perceptual experience can be exhaustively characterized solely by reference to its Intentional content. Strong or Pure Anti-Intentionalism is the claim that the phenomenal character of any perceptual experience can be exhaustively characterized solely by reference to its non-Intentional properties. In Chapters One and Two, I consider how best to delineate the opposition between these positions. I reject various characterizations of the distinction, in particular, that it can be (...) captured in modal terms. Pure Intentionalist and Pure Anti-Intentionalist accounts can in fact share a modal profile. The most fundamental way of distinguishing Intentionalism from Anti-Intentionalism is in terms of the Intentionalist claim that experiences have contents with truth or satisfaction conditions. Characterized in this way, Intentionalism is committed to the claim that perceptual experience exhibits a certain kind of generality in that perceptual experiences essentially present their objects as being certain general ways. In contrast, the anti-Intentionalist denies that talk of seeing objects as certain kinds of object or as particular objects of those kinds provides a characterization of any aspect of the phenomenal character of perceptual experience. Anti-Intentionalist theories must, therefore, account for phenomenal character wholly in terms of particularist properties. In Chapters Three and Four, I argue that neither of these pure views of experience can do justice to the phenomenology of our ordinary perceptual encounters with the world. In Chapter Three, I contend that Pure Anti- Intentionalism, at least in the form of Bill Brewer’s Object View, fails to provide a satisfactory account of the phenomenology of aspect shifts and continuous aspect perception. Furthermore, I argue that the Object View’s accounts of perceptual illusion are ill-motivated and fundamentally unsatisfactory. In Chapter Four, I argue that Pure Intentionalism is inconsistent with the phenomenologically evident fact that experiences are durational events which unfold over time. Accordingly, the assumption that the phenomenal character of perceptual experience must be wholly characterized in terms of one kind of property, be it Intentionalist or non-Intentionalist, should be rejected. Any plausible theory of experience must appeal to different kinds of phenomenal property. In Chapter Five, I defend a view which does just this: the Catholic View of experience. The Catholic View claims that the phenomenal character of any mature human experience must be characterized in terms of both particularist and Intentional properties. I conclude by showing how this account avoids the most serious criticisms that have been levelled against the idea of non-representational, or ‘given’ elements in experience. (shrink)
