In the Introduction to Self to Self, J. David Velleman claims that 'the word "self" does not denote any one entity but rather expresses a reflexive guise under which parts or aspects of a person are presented to his own mind' (Velleman 2006, 1). Velleman distinguishes three different reflexive guises of the self: the self of the person's self-image, or narrative self-conception; the self of self-sameness over time; and the self as autonomous agent. Velleman's account of each of these different guises of the self is complex and repays close philosophical attention. The first aim of this paper is therefore to provide a detailed analysis of Velleman's view. The second aim is more critical. While I am in agreement with Velleman about the importance of distinguishing the different aspects of selfhood, I argue that, even on his own account, they are more interrelated than he acknowledges. I also analyse the role of the concept of 'bare personhood' in Velleman's approach to selfhood and question whether this concept can function, as he wants it to, to bridge the gap between a naturalistic analysis of reasons for action and Kantian moral reasons.

A critical discussion of Barry Stroud's claim, in his book The Quest for Reality, that we could never rationally arrive at the conclusion that, for example, the world is not really colored.

Realists about color, be they dispositionalists or physicalists, agree on the truth of the following claim: (R) x is red iff x is disposed to look red under standard conditions. The disagreement is only about whether to identify the colors with the relevant dispositions, or with their categorical bases. This is a question about the representational content of color experience: What kind of properties do color experiences ascribe to objects? It has been argued (for instance by Boghossian and Velleman, 1991) that truths like (R) cannot be used in an account of the colors as they would result in ‚circular’, and therefore empty, contents. It has also been argued (for instance by Harman, 1996) that switching to an account of color in terms of a functional account of color sensations would result in a circular, and therefore empty, account. In this paper, I defend a realist account of color in terms of a (non-reductive) functional account of color sensations. Such an account of sensations has been suggested by Pagin (2000), and it can be applied to color sensations without the resulting account of the colors themselves being circular or empty. I argue that the so-called transparency of experience does not provide any argument against such an account. I also argue that on such an account, the issue of physicalism vs. dispositionalism boils down to the question of the modal profile of the color concepts.

Frank Jackson and Robert Pargetter (1987)2 have argued for a version of reductive physicalism about color which they claim can accommodate the basic intuitions that have led others to embrace dispositionalism or subjectivism about color. Jackson (1996) has further developed the view and provided responses to some objections to its original statement. While Jackson and Pargetter do not have much company in endorsing their specific form of color physicalism, elements of their view have shown up in other realist accounts, including the relativized account of color offered by John Spackman (2002), the disjunctivism of color properties endorsed by Peter Ross (2000), and the subjectivist strain present in Sydney Shoemaker’s (1994) discussion of color.3 Additionally, Mark Johnston (1992) has used Jackson and Pargetter’s view as a principal target in his arguments against color physicalism.

A brief description of the goal and main lines of argument of The Quest for Reality, in reply to the responses of Paul Boghossian and Alex Byrne.

I defend externalism about color experiences and color thoughts, which I argue color objectivism requires. Externalists face the following question: would a subject’s wearing inverting lenses eventually change the color content of, for instance, those visual experiences the subject reports with “red”? From the work of Ned Block, David Velleman, Paul Boghossian, Michael Tye, and Fiona Macpherson, I extract problems facing those who answer “Yes” and problems facing those who answer “No.” I show how these problems can be overcome, leaving externalism available to the color objectivist.
