Alfred Mele’s zygote argument is widely considered to be the strongest version of the manipulation argument against compatibilism (about free will and determinism). Opponents have focused largely on the first of its two premises and on the overall dialectic. My focus here will be on the underlying thought experiment—the Diana scenario—and on the second premise of the argument. I will argue that reflection on the Diana scenario shows that the second premise does not hold, and we will see that my objection to the second premise helps to defend the claim that manipulation arguments face, in general, a dilemma

Most contemporary philosophers of action agree on the following claims. Firstly, the possibility of deviant or wayward causal chains poses a serious problem for the standard-causal theory of action. Secondly, we can distinguish between different kinds of deviant causal chains in the theory of action. In particular, we can distinguish between cases of basic and cases of consequential deviance. Thirdly, the problem of consequential deviance admits of a fairly straightforward solution, whereas the possibility of basic deviance constitutes a separate and difficult problem that requires its own solution. I will argue that the problem of basic deviance is no more troublesome than the problem of consequential deviance, as a solution to the former is implicit in the standard solution to the latter.

Traditional compatibilism about free will is widely considered to be untenable. In particular, the conditional analysis of the ability to do otherwise appears to be subject to clear counterexamples. I will propose a new version of traditional compatibilism that provides a conditional account of both the ability to do otherwise and the ability to choose to do otherwise, and I will argue that this view withstands the standard objections to traditional compatibilism. For this, I will assume with incompatibilists that the mere possession of a general ability to do otherwise is not sufficient for having the ability that is required for free will. This concession distinguishes the view from the traditional conditional analysis and from recent dispositional accounts of the ability to do otherwise, and we will see that this concession enables a straightforward response to the counterexamples. This, in turn, will play a crucial role in my response to the strongest version of the consequence argument for incompatibilism.

This paper proposes and defends an account of what it is to act for reasons. In the first part, I will discuss the desire-belief and the deliberative model of acting for reasons. I will argue that we can avoid the weaknesses and retain the strengths of both views, if we pursue an alternative according to which acting for reasons involves taking something as a reason. In the main part, I will develop an account of what it is to take something as a reason for action. On the basis of this, I will then offer a new account of what it is to act for reasons.
