Is knowledge necessary or sufficient or both necessary and sufficient for acceptable practical reasoning and rational action? Several authors (e.g., Williamson, Hawthorne, and Stanley) have recently argued that the answer to these questions is positive. In this paper I present several objections against this view (both in its basic form as well in more developed forms). I also offer a sketch of an alternative view: What matters for the acceptability of practical reasoning in at least many cases (and in all the cases discussed by the defenders of a strong link between knowledge and practical reasoning) is not so much knowledge but expected utility.

Are there moral truths? Are (at least some) moral statements or beliefs „true“ or „false“ in the sense of a correspondence theory of truth? Are there moral facts that make those statements or beliefs true or false? In this paper I propose an argument against the idea that moral sentences and beliefs have truth-conditions in that sense. The argument focuses on the semantic and epistemic status of those beliefs and sentences. I also argue that all this does not lead to a subjectivist interpretation of morality.

Are we free? What does "freedom" mean here? In the following, I shall only focus with freedom of action. My main thesis is that there is not just one basic type of free action but more. Philosophers, however, tend to assume that there is just one way to act freely. Hence, a more detailed analysis of free action is being called for. I will distinguish between different kinds of free action and discuss the relations between them. The analysis of different types of coercion will lead to a different view on freedom – a view which stresses the many faces of free action.

In his recent book Moral Skepticisms Walter Sinnott-Armstrong argues in great detail for contrastivism with respect to justified moral belief and moral knowledge. I raise three questions concerning this view. First, how would Sinnott-Armstrong account for constraints on admissible contrast classes? Secondly, how would he deal with notorious problems concerning relevant reference classes? Finally, how can he account for basic features of moral agency? It turns out that the last problem is the most serious one for his account.
