In this paper I argue that certain so-called conceivability arguments fail to show that a currently popular version of physicalism in the philosophy of mind is false. Concentrating on an argument due to David Chalmers, I first argue that Chalmers misrepresents the relation between conceivability and possibility. I then argue that the intuition behind the conceivability of so-called zombie worlds can be accounted for without having to suppose that such worlds are genuinely conceivable. I conclude with some general remarks about the nature of conceivability.

My aim in this paper is to argue that justification should not be conceived of in purely objective terms. In arguing for that conclusion I focus in particular on Paul Robinson’s presentation of that position, since it is the most sophisticated defense of the objective account of justification in the literature. My main point will be that the distinction drawn by Robinson between objective and subjective accounts of justification is problematic, and that careful attention to the role played by reasonableness in subjectivist accounts of justification reveals that the apparent puzzles Robinson raises for subjectivism are merely apparent. I will suggest that we ought to be reasonable subjectivists about justification, where “reasonableness” is understood in a particular manner. This has consequences for various other issues, including how we make sense of mistaken justification, and I will have something to say about those issues as they arise along the way.
