In this paper I discuss Fred Dretske's account of knowledge critically, and try to bring out how his account of informational content leads to cases of extreme epistemic good luck in his treatment of knowledge. My main interest, however, is to establish that the cases of epistemic luck arise because Dretske's account of knowledge in a fundamental way fails to take into account the role our actual recognitional capacities and powers of discrimination play in perceptually based knowledge. This result is, I believe, new. The paper has three sections. In Section 1 I give a short exposition of Dretske's theory, and make some necessary qualifications about how it is to be understood. In Section 2 I discuss in greater detail how the theory actually works, and provide some examples I think are very troublesome for Dretske. In Section 3 I argue that these cases establish my main claim. I also show that there are cases of epistemic bad luck due to Dretske's account of how information causes belief

David Hunter has recently argued that Donald Davidson and Elizabeth Anscombe were in basic agreement about practical knowledge. In this reply, it is my contention that Hunter’s fascinating claim may not be satisfactorily warranted. To throw light on why, a more careful consideration of the role of the notion of practical knowledge in Anscombe’s approach to intentional action is undertaken. The result indicates a possible need to distinguish between what is called ‘practical knowledge’ and ‘ knowledge of what one is doing’, and shows that Hunter’s claim concerning the closeness of Anscombe to Davidson only has plausibility for knowledge of what one is doing. Contrary to an interesting suggestion by Hunter, the paper argues that it is hard to see how Davidson’s position can benefit substantially from making use of the notion of knowledge of what one is doing.

In his target article and recent interesting book about addiction and the brain, Marc Lewis claims that the prevalent medical view of addiction as a brain disease or a disorder, is mistaken. In this commentary we critically examine his arguments for this claim. We find these arguments to rest on some problematical and largely undefended assumptions about notions of disease, disorder and the demarcation between them and good health. Even if addiction does seem to differ from some typical brain diseases, we believe contrary to Lewis, that there are still good reasons to maintain its classification as a mental or behavioral disorder.
