Workshop descriptionThere has recently been increased interest in the nature of a broad class of sensibilia, including, but not restricted to, colours, sounds, flavours, odours, tactile qualities, and shadows. Debates about the nature of these sensibilia raise similar questions to discussions about perceptual experience more generally: (i) what exactly are philosophical theories of sensibilia supposed to explain, (ii) what are the fixed points from which theorising should proceed, and (iii) what is the methodology that such theorising should employ? The topic of this workshop will be these questions about sensibilia, and their relationship to wider debates about the nature of perception and consciousness. Many of the disagreements about the nature of these sensibilia mirror disagreements between physicalist and non-physicalist approaches to mental phenomena. Non-reductive theories of sensibilia are becoming increasing popular, with a number of writers suggesting that these non-reductive theories have an important bearing on theories of the nature of perception, and may even play a central role in dissolving problems relating to the nature of consciousness: for instance, perhaps “what it is like” to perceive colour, sound, or smell, is not to be explained by an irreducible qualitative property of experience, or some physically realized representational brain state, but instead by the qualitative nature of the colours, sounds, and smells perceived (e.g. Campbell 1993; Kalderon 2007; Fish 2009). 

The workshop is funded by a Templeton-supported New Directions grant to the project Purpose and Procedure in Philosophy of Perception.

David Macarthur, University of Sydney: Quining Colour Qualia

Abstract: Dennett is famous for attempting to ‘quine’ qualia in general. Here I want to ‘quine’ colour qualia in particular. The aim will be to show not that colour qualia do not exist because that assumes their possible existence. Rather I want to show that the picture of colour perception upon which the doctrine of colour qualia rests is confused.

Louise Moody, University of York: Neither Phenomenal Internalism nor Phenomenal Externalism: How Combining both can Settle Three Disputes about Phenomenal Character

Abstract: Perceptual phenomenal character (i.e. the subjective character of perceptual experience), according to the Phenomenal Internalist (e.g. Hellie 2007; Kriegel 2009), is intrinsically constituted by internal, or ‘skin-in’, factors (typically, electrochemical properties of the experiencing subject’s brain); a claim that is denied by the Phenomenal Internalist (e.g. Campbell 2002; Martin 2004) who contends that phenomenal character is intrinsically constituted by external, or ‘skin-out’, factors (typically, the perceptible properties of worldly objects with which the experiencing subject is directly acquainted). The present paper explores the prospects for unifying both views in the form of a view.that I call Phenomenal Hybridism – that is, I consider if phenomenal character might metaphysically spring from internal and external factors. At first sight, Phenomenal Hybridism enjoys.three explanatory advantages over its rivals: namely, it (i) can disentangle some conceptual confusion that surrounds the concept phenomenal character, (ii) can diffuse the intuitive stand-off between.the Internalist and Externalist, and, (iii) offers an alternative account that can be accepted by either the Conjunctivist (i.e. someone who thinks that veridical and non-veridical experiences share a common phenomenal ingredient, to which a normal – standardly causal – relation is conjoined between that ingredient and mind-independent reality in the former case) or the Naïve Realist (i.e. someone who thinks that veridical perceptual experiences are essentially of, and immediately acquaint us with, aspects of mind-independent reality). I conclude with one moral from (i)-(iii).

Thomas Raleigh, NTNU: Naive-Realism & The Explanatory Gap

Abstract: Of the many possible motivations for Naïve-Realism, one that has received relatively little discussion is the theory’s alleged ability to help solve the ‘Explanatory Gap’ – e.g. Fish (2008, 2009), Langsam (2011). I provide a reformulation of this general line of thought that makes clearer how and when a Relational theory of perceptual experience could help to explain the specific phenomenal nature of such experience. In particular, I show how and why this form of explanation will work best for the case of visual shape phenomenology rather than colour phenomenology. I also argue that the relational theory can give a natural explanation for why we should expect colour phenomenology to remain less readily intelligible than shape phenomenology.

Workshop Description:

This first workshop will be in Leeds, focused on the general topic of perceptual phenomenal character (roughly, “what it is like” to have an experience). Many regard accounting for phenomenal character as one of the primary desiderata on philosophical theories of perceptual experience—for example, in the debate between Naïve Realists and Intentionalists over the metaphysics of perceptual experience (e.g., Fish 2009), and in the debate over experience of “high-level” properties (e.g., Siegel 2011). However, others (e.g., Hacker 2002) have argued that that there is no stable phenomenon here in need of explanation; that the explanatory target is ill-defined or confused. The main aim of this workshop will be to get clearer about the alleged explanandum—a task which is central to the concerns of the New Directions project, insofar as phenomenal character is particularly resistant to physicalist reduction. Questions addressed might include: can we defend the notion of phenomenal character from charges of incoherence or confusion? Is there more to the notion of perceptual phenomenal character than how things appear to the subject (e.g., a distinctive “feel” infusing perceptual appearances)? Must we think of perceptual phenomenal character as entirely “in the head”?
