Abstract: Ambiguous figures pose a problem for representationalists, particularly for representationalists who believe that the content of perceptual experience is non-conceptual (MacPherson in Nous 40(1):82–117, 2006). This is because, in viewing ambiguous figures, subjects have perceptual experiences that differ in phenomenal properties without differing in non-conceptual content. In this paper, I argue that ambiguous figures pose no problem for non-conceptual representationalists. I argue that aspect shifts do not presuppose or require the possession of sophisticated conceptual resources and that, although viewing ambiguous figures often causes a change in phenomenal properties, this change is accompanied by a change in non-conceptual content. I illustrate the case by considering specific examples.

Abstract: Disjunctivist theories of perceptual experience claim that veridical and non-veridical experiences are radically unalike in some respect (other than the obvious difference in their causal histories). This chapter outlines four ways of elaborating this basic claim, each motivated by a different concern. The first is disjunctivism about the objects of experience, motivated by Direct Realism. The second is disjunctivism about the content of experience, motivated by the view that some experiences have object-dependent content. The third is disjunctivism about perceptual evidence (also known as epistemological disjunctivism), which is a strategy for responding to a particular sort of argument for scepticism about the external world. The fourth is disjunctivism about the metaphysical structure of experience (also known as metaphysical disjunctivism), which is motivated by Naïve Realism (a species of Direct Realism).

Abstract: I argue that there are phenomenological constraints on what it is to see an object, and that these are overlooked by some theories that offer allegedly sufficient causal and counterfactual conditions on object-seeing.

Abstract: This paper contrasts two enactive theories of visual experience: the sensorimotor theory (O’Regan and Noë, Behav Brain Sci 24(5):939–1031, 2001; Noë and O’Regan, Vision and mind, 2002; Noë, Action in perception, 2004) and Susan Hurley’s (Consciousness in action, 1998, Synthese 129:3–40, 2001) theory of active perception. We criticise the sensorimotor theory for its commitment to a distinction between mere sensorimotor behaviour and cognition. This is a distinction that is firmly rejected by Hurley. Hurley argues that personal level cognitive abilities emerge out of a complex dynamic feedback system at the subpersonal level. Moreover reflection on the role of eye movements in visual perception establishes a further sense in which a distinction between sensorimotor behaviour and cognition cannot be sustained. The sensorimotor theory has recently come under critical fire (see e.g. Block, J Philos CII(5):259–272, 2005; Prinz, Psyche, 12(1):1–19, 2006; Aizawa, J Philos CIV(1), 2007) for mistaking a merely causal contribution of action to perception for a constitutive contribution. We further argue that the sensorimotor theory is particularly vulnerable to this objection in a way that Hurley’s active perception theory is not. This presents an additional reason for preferring Hurley’s theory as providing a conceptual framework for the enactive programme.

Abstract: A recent study published in Nature Neuroscience purports to have answered a question posed to Locke in 1688 by his friend William Molyneux, namely, whether ‘a man born blind and made to see’ would be able to identify, immediately and by vision alone, objects previously known only by touch. The answer, according to the researchers – and as predicted by Molyneux, as well as Locke, Berkeley, and others – is ‘likely negative. The newly sighted subjects did not exhibit an immediate transfer of their tactile shape knowledge to the visual domain’. Since then, however, many commentators have argued that the answer is still not clear. Moreover, in the contemporary literature on Molyneux’s Question, and more generally on cross-modal perception and the individuation of the senses, it is sometimes hard to determine what question is being investigated. In this paper, I distinguish a number of different questions about the relation between visual and tactual perception that can arise when considering Molyneux’s problem.

Abstract: The view that physical objects do not, in fact, possess colour properties is certainly the dominant position amongst scientists working on colour vision. It is also a reasonably popular view amongst philosophers. However, the recent philosophical debate about the metaphysical status of colour properties seems to have taken a more realist turn. In this article, I review the main philosophical views – eliminativism, physicalism, dispositionalism and primitivism – and describe the problems they face. I also examine how these views have been classified and suggest that there may be less disparity between some of these positions than previously thought

Abstract: The paper reviews the empirical evidence for highly significant variation across perceivers in hue perception and argues that color physicalism cannot accommodate this variability. Two views that can accommodate the individual differences in hue perception are considered: the self-locating property theory, according to which colors are self-locating properties, and color relationalism, according to which colors are relations to perceivers and viewing conditions. It is subsequently argued that on a plausible rendition of the two views, the self-locating theory has a slight advantage over color relationalism in being truer to the phenomenology of our color experiences

Abstract: What distinguishes a conscious occurrent thought from a non-conscious occurrent thought? I argue that the notion of 'access-consciousness' cannot provide a satisfactory answer and that we must appeal to phenomenological properties. If this is right, a further question arises about what kind of phenomenological features are required. Can we give a satisfactory account of what makes an occurrent thought a conscious thought solely by reference to sensory phenomenology - including both verbal and non-verbal imagery? I argue that we cannot, and that we must appeal to 'cognitive phenomenology' in order to be able to say what distinguishes conscious occurrent thought from non-conscious occurrent thought.

Publisher's Note: Does God exist? What are the various arguments that seek to prove the existence of God? Can atheists refute these arguments? The Existence of God: A Philosophical Introduction assesses classical and contemporary arguments concerning the existence of God: the ontological argument, introducing the nature of existence, possible worlds, parody objections, and the evolutionary origin of the concept of God the cosmological argument, discussing metaphysical paradoxes of infinity, scientific models of the universe, and philosophers' discussions about ultimate reality and the meaning of life the design argument, addressing Aquinas's Fifth Way, Darwin's theory of evolution, the concept of irreducible complexity, and the current controversy over intelligent design and school education. Bringing the subject fully up to date, Yujin Nagasawa explains these arguments in relation to recent research in cognitive science, the mathematics of infinity, big bang cosmology, and debates about ethics and morality in light of contemporary political and social events. The book also includes fascinating insights into the passions, beliefs and struggles of the philosophers and scientists who have tackled the challenge of proving the existence of God, including Thomas Aquinas, and Kurt Godel - who at the end of his career as a famous mathematician worked on a secret project to prove the existence of God. The Existence of God: A Philosophical Introduction is an ideal gateway to the philosophy of religion and an excellent starting point for anyone interested in arguments about the existence of God

Abstract: The basic philosophical controversy regarding ordinary objects is: Do tables and chairs, sticks and stones, exist? This paper aims to do two things: first, to explain why how this can be a controversy at all, and second, to explain why this controversy has arisen so late in the history of philosophy. Section 1 begins by discussing why the 'obvious' sensory evidence in favor of ordinary objects is not taken to be decisive. It goes on to review the standard arguments against the existence of ordinary objects - including those based on problems with causal redundancy, parsimony, co-location, sorites arguments, and the special composition question. Section 2 goes on to address what it is about the contemporary approach to metaphysics that invites and sustains this kind of controversy, and helps make evident why debates about ordinary objects lead so readily to debates in metametaphysics about the nature of metaphysics itself.
