In this paper, I present an argument that shows that the belief in libertarian freedom is inconsistent with two assumptions widely accepted by those who are physicalists with regard to the relation between the mental and the physical - that mental properties are distinct from physical properties, and that mental properties supervene on physical properties. After presenting the argument, I trace its implications for the question of the compatibility of libertarian free will and physicalism in general.

Recently, John Fischer has proposed a novel account of the hard/soft distinction which is an entailment account. At its basis is the idea that a fact about a time T as a soft fact about T if it entails a fact about a time later than T; and a fact about a time T as a hard fact about T if it does not do so. Elsewhere, I have expressed serious doubts whether an entailment account of the hard/soft fact distinction can succeed. Thus, it is surprising that Fischer's new account, too, turns out to be inadequate, or so at least I shall argue.
