The Problem of Perception is a pervasive and traditional problem about our ordinary conception of perceptual experience. The problem is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perceptual experience be what we ordinarily understand it to be: something that enables direct perception of the world? These possibilities of error challenge the intelligibility of our ordinary conception of perceptual experience; the major theories of experience are responses to this challenge.

A preview of my book *Perception*. Discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, (...) suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

This dissertation aims to revive wave theory in the philosophy of sound. Wave theory identifies sounds with compression waves. Despite its wide acceptance in the scientific community as the default position, many philosophers have rejected wave theory and opted for different versions of distal theory instead. According to this current majority view, a sound has its stationary location at its source. I argue against this and other alternative philosophical theories of sound and develop wave theory into a more defensible form. (...) Philosophers of sound tend to emphasise how sounds are experienced to be in their arguments. Most often, it is assumed that that which appears to be a distally located bearer of auditory properties in an auditory experience is a sound. Chapter 1 argues that if this distal entity is the sound source instead, many of the existing theories of sound will be severely affected. Chapter 2 discusses auditory perception and criticises the common assumption that we hear non-sound entities in virtue of hearing sounds. I show that this assumption begs the question against certain theories of sound and that the contrary view that sound sources can be directly heard is more plausible. If sound sources can be directly heard, then features commonly attributed to sounds based on auditory experiences might rather be features of sound sources. I examine eight of such features in Chapter 3. Only four of them survive. Chapters 4 and 5 review the existing theories of sound. After a taxonomy of existing theories of sound, each theory is criticised one-by-one. Some of them are problematic precisely because they rely on the implausible assumption that that which appears to be distally located in an auditory experience is a sound rather than a sound source. Lastly, Chapter 6 focuses on wave theory. It begins with two positive arguments for wave theory in general, followed by my replies to two common objections in the literature. I then move on to develop my version of wave theory. There are two core aspects of my view. The first one is a metaphysics of compression waves; the second is an account of what it is to hear compression waves. After comparing my view with a similar theory, I demonstrate the explanatory power of my view in two steps. First, the eight commonly accepted features of sounds examined in Chapter 3 are revisited. It turns out that my view can accommodate all of them. Second, explanations for four special sound-related phenomena are offered at the end of the chapter. I conclude in the last chapter with the suggestion that, as a philosopher, the best way to defend wave theory is to offer a better understanding of auditory perception which explains how compression waves are experienced.

‘How, then, she had asked herself, did one know one thing or another thing about people, sealed as they were?’ So asks Lily Briscoe in To the Lighthouse. It is this question, rather than any concern about pretence or deception, which forms the basis for the philosophical problem of other minds. Responses to this problem have tended to cluster around two solutions: either we know others’ minds through perception; or we know others’ minds through a form of inference. In the (...) first part of this paper I argue that this debate is best understood as concerning the question of whether our knowledge of others’ minds is based on perception or based on evidence. In the second part of the paper I suggest that our ordinary ways of thinking take our knowledge of others’ minds to be both non- evidential and non-perceptual. A satisfactory resolution to the philosophical problem of other minds thus requires us to take seriously the idea that we have a way of knowing about others’ minds which is both non-evidential and non-perceptual. I suggest that our knowledge of others’ minds which is based on their expressions – our expressive knowledge - may fit this bill. (shrink)

Object perception deploys a suite of perceptual capacities that constrains attention, guides reidentification, subserves recognition, and anchors demonstrative thought. Objects for perception—perceptual objects—are the targets of such capacities. Characterizing perceptual objects for multisensory perception faces two puzzles. First is the diversity of objects across sensory modalities. Second is the unity of multisensory perceptual objects. This paper resolves the puzzles. Objects for perception are structured mereologically complex individuals. Perceptual objects are items that bear perceptible features and have perceptible parts arranged to (...) form a unified whole. This circumscribes the targets of object perception where neutral talk concerning intentional objects and objects of perception cannot. Nonetheless, it is more permissive than identifying perceptual objects with material bodies, which excludes too much and leans too heavily on vision. The account thus is tailored to capture the role of objects in perception beyond vision: tactual, auditory, and olfactory objects are individuals with differing structures. Its flexibility also enables the account to accommodate shared objects for multisensory perception: multisensory perceptual objects are mereologically complex individuals with hybrid structure. For instance, one can bimodally perceive a common whole with parts accessible to one but not both modalities. Each sense provides a partial perspective on a complex whole that is perceptible through the coordinated use of multiple senses. Understanding perceptual objects as structured mereologically complex individuals thus provides a theoretically useful notion of an object for multisensory perception that resolves the puzzles of diversity and of unity.

Through hearing we learn about source events: events in which objects move or interact so that they vibrate and produce sound waves, such as when they roll, collide, or scrape together. It is often claimed that we do not simply hear sounds and infer what event caused them, but hear source events themselves, through hearing sounds. Here I investigate how the idea that we hear source events should be understood, with a focus on how hearing an event relates to hearing (...) the objects involved in that event. I argue that whereas we see events such as rollings and collisions by seeing objects move through space, this cannot be how we hear them, and go on to examine two other possible models. On the first, we hear events but not their participant objects. On the second, to hear an event is to hear the appearance of an object to change. I argue that neither is satisfactory and endorse a third option: to hear a source event is to hear an object as extending through time. (shrink)

In this paper I argue that the work of the unorthodox Stoic Posidonius - as reported to us by Galen - can be seen as making an interesting contribution to contemporary debates about the nature of emotion. Richard Sorabji has already argued that Posidonius' contribution highlights the weaknesses in some well-known contemporary forms of cognitivism. Here I argue that Posidonius might be seen as advocating a theory of the emotions which sees them as being, in at least some cases, two-level (...) intentional phenomena. One level involves judgments, just as the orthodox Stoic account does. But Posidonius thinks that emotions must also include an element sometimes translated as an "irrational tug". I suggest that we see the "irrational tug" as involving a second level of intentional, but non-conceptual representation. This view satisfies two desiderata: it is a view which would have been available to Posidonius and which is compatible with the views reported to us; and it is a view which is independently attractive. It also makes Posidonius' position less far removed from that of orthodox Stoics than it might otherwise do, while remaining genuinely innovative. (shrink)

Sometimes we remember past objects or events in a vivid, experiential way. The present paper addresses some fundamental questions about the metaphysics of such experiential or ‘recollective’ memories. More specifically, it develops the ‘Relational Account’ of recollective memory, which consists of the following three claims. A subject who recollectively remembers a past object or event stands in an experiential relation to the relevant past object or event. The R‐remembered object or event itself is a part of the R‐memory; that is, (...) the subject's present R‐memory is partly constituted by the relevant past object or event. When a subject R‐remembers a past object, the past object is a constitutive part of the conscious experience itself; that is, the object is immediately available to the subject in conscious experience. In developing the Relational Account, the present paper hopes to make a substantial contribution to any attempt to account for the nature of recollective memory. Furthermore, in order to explain how a subject could understand the beliefs that she forms about the past on the basis of an R‐memory, and how a subject could, on the basis of an R‐memory, gain any knowledge about the past, we arguably also need to rely on the Relational Account of recollective memory. Thus, the Relational Account will also play an important role in an attempt to account for various other ways in which a subject might be related to the past in general, and to her own past in particular. Standing in such relations to the past is, in turn, a central feature of our human existence. Ultimately, therefore, the Relational Account of recollective memory should also play a crucial role in furthering our understanding of ourselves, and of our own existence in time. (shrink)

According to Duncan Pritchard’s version of epistemological disjunctivism, in paradigm cases of perceptual knowledge, one’s knowledge that p is grounded in one’s seeing that p, and one can, by reflection alone, come to know that they see that p. In this paper, I argue that the epistemic conception of introspective indiscriminability is incompatible with epistemological disjunctivism, so understood. This has the consequence that theories of the nature of sensory experience which accept the epistemic conception of introspective indiscriminability—such as phenomenal character (...) disjunctivism and certain forms of naïve realism—are inconsistent with epistemological disjunctivism, so understood. I then argue that proponents of epistemological disjunctivism face a formidable challenge explaining in what sense, if any, one can have purely reflective knowledge of their factive rational support.
