This paper develops a sympathetic critique of recent experimental work on free will and moral responsibility. Section 1 offers a brief defense of the relevance of experimental philosophy to the free will debate. Section 2 reviews a series of articles in the experimental literature that probe intuitions about the "compatibility question"—whether we can be free and morally responsible if determinism is true. Section 3 argues that these studies have produced valuable insights on the factors that influence our judgments on the compatibility question, but that their general approach suffers from significant practical and philosophical difficulties. Section 4 reviews experimental work addressing other aspects of the free will/moral responsibility debate, and section 5 concludes with a discussion of avenues for further research.

I aim to alleviate the pessimism with which some philosophers regard the 'objective attitude', thereby removing a particular obstacle which P.F. Strawson and others have placed in the way of more widespread scepticism about moral responsibility. First, I describe what I consider the objective attitude to be, and then address concerns about this raised by Susan Wolf. Next, I argue that aspects of certain attitudes commonly thought to be opposed to the objective attitude are in fact compatible with it. Finally, I examine the prospects of someone who wishes to adopt the objective attitude permanently. In response to philosophers who claim that this would be psychologically impossible, I argue that our commitment to attitudes that presuppose moral responsibility can soften and fade, often without our noticing it

In this paper I challenge the core of David Chalmers' argument against materialism-the claim that "there is a logically possible world physically identical to ours, in which the positive facts about consciousness do not hold." First, I analyze the move from conceivability to logical possibility. Following George Seddon, I consider the case of a floating iron bar and argue that even this seemingly conceivable event has implicit logical contradictions in its description. I then show that the distinctions Chalmers employs between primary and secondary intensions, and a priori and a posteriori entailment, break down upon close examination-with iron bars and with consciousness it is impossible to know where primary intensions end and secondary intensions begin. I extend this analysis of logical possibility to the famous zombie thought experiment and conclude not that a zombie world is logically impossible, but rather that, at present, the question is open. Finally, I show how a similar line of argument may be used to undermine the "Mary the color scientist" thought experiment as well
