Stance-independent nonnaturalist moral realism is subject to two related epistemological objections. First, there is the metaethical descendant of the Benacerraf problem. Second, there are evolutionary debunking arguments. Standard attempts to solve these epistemological problems have not appealed to any particular moral epistemology. The focus on these epistemologically neutral responses leaves many interesting theoretical stones unturned. Exploring the ability of particular theories in moral epistemology to handle these difficult epistemological objections can help illuminate strengths or weaknesses within these theories themselves, as (...) well as opening up potentially unexplored avenues for responding to deeply entrenched concerns about our epistemic access to the moral properties. In this paper, I assess the prospects of an empiricist and perceptualist model of moral knowledge for responding to epistemological arguments against non-skeptical moral realism. I argue that such a view has powerful responses to these objections that are not open to other moral epistemologists. The upshot is that if some version of the view is correct, then the realist has less to fear from Benacerraf and evolutionary debunking–style epistemological objections. Insofar as one is already a committed realist, then, this provides some indirect support for moral perceptualism. (shrink)

It is widely accepted that there is a visual field, but the analogous notion of an auditory field is rejected by many philosophers on the grounds that the metaphysics or phenomenology of audition lack the necessary spatial or phenomenological structure. In this paper, I argue that many of the common objections to the existence of an auditory field are misguided and that, contrary to a tradition of philosophical scepticism about the spatiality of auditory experience, it is as richly spatial as (...) visual experience—and in some ways even more so. By carefully considering the spatiality and boundedness of audition, along with how sounds or their sources are experienced as occurring within the surrounding acoustic environment, we can gain a better understanding of (i) our auditory experience of space and (ii) the conditions for the existence of spatial sensory fields in general in a way that does not privilege vision over the other senses.

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

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.

Theorists have recently defended rival analyses of sound. The leading analyses reduce sound to sensations or mental representations, longitudinal compression waves, or sounding objects or events. Participants in the debate presuppose that because the features of the world targeted by these reductive strategies are distinct, at most one of the analyses is correct. In this article I argue that this presupposition is mistaken, endorsing a polysemy analysis of ‘sound’. Thus the ‘What is sound?’ debate is largely merely verbal, or so (...) I argue. All participants in this debate agree that there are the various reductions, they simply differ over which of them ‘is sound’. Yet there is no reason to think that, say, psychologists studying auditory sensations/representations, audio physicists studying sound waves, and anthropologists/ethnomusicologists studying sounding objects/events aren’t just studying different reductions of ‘sound’ despite the different explananda of their research. According to the polysemy theory of sound, we do not need to uniquely identify sound with one of these various explananda, outside of some context. (shrink)

When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, according to which we (...) represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”. (shrink)

ABSTRACTWhat is John Cage's 4′33″? This paper disambiguates this question into three sub-questions concerning, respectively, the work's ontological nature, the art form to which it belongs, and the genre it is in. We shall see that the work's performances consist of silence, that it is a work of performance art, and that it belongs to the genre of conceptual art. Seeing the work in these ways helps us to understand it better, and promises to assuage somewhat the puzzlement and irritation (...) of those who are at first resistant to its charms. (shrink)

What is the relationship between sounds and time? More specifically, is there something essentially or distinctively temporal about sounds that distinguishes them from, say, colors, shapes, odors, tastes, or other sensible qualities? And just what might this distinctive relation to time consist in? Apart from their independent interest, these issues have a number of important philosophical repercussions. First, if sounds are temporal in a way that other sensible qualities are not, then this would mean that standard lists of paradigm secondary (...) qualities offered by Locke, Galileo, and other modern philosophers — lists which include colors, odors and sounds without any significant distinctions — overlook significant metaphysical differences. This, in turn, would threaten to undermine the coherence of the modern understanding of secondary qualities itself. Moreover, a number of authors have recently urged that the essential temporality of sounds makes it impossible to understand sounds as properties (except on a trope theory of properties; see note 3). If true, and given the more or less universal view that colors are properties, this last conclusion would make potentially inapplicable to sounds much of the comparatively well-developed philosophical taxonomy and apparatus that has arisen in philosophical disputes over the status of colors (for presentations of this taxonomy and apparatus see, for example, Byrne and Hilbert (2003); Cohen (2008b)).1 Therefore, the conclusion that sounds are distinctively temporal would be a serious blow to hopes for a theoretically unified treatment of the sensory qualities.2 For all these reasons, quite a lot seems to hang on the question of the temporality of sounds.

In the recent literature on the nature of sound, there is an emerging consensus rejection of what might be thought of as the scientifically informed commonsense position: that sounds, whatever else they may be, must be entities that mediate between the source of the sound and the subject hearing it. This paper offers an argument for such "medial" theories of sound. This argument is intended to shift attention from the two considerations that have dominated the debate thus far: the relevant (...) scientific facts about audition and the spatial phenomenology of auditory experience.

I argue that chimericity is a property that we typically experience when listening to multi-instrumental music. It is the property of hearing as a unified whole a melody or a harmony that does not belong to any single sound source but instead consists of the assembling of melodic or harmonic fragments coming from different sources. Chimericity is not reducible to the low-level audible properties of pitch and loudness; it is cognized at the perceptual level thanks to the auditory mechanism of (...) primitive grouping. My aim is to show that chimericity is a perceptual property, one that we can genuinely hear. In developing this view, I engage with the debate within the philosophy of sense perception between rich vs thin views of the content of perceptual experience. (shrink)
