This paper presents an argument for the claim that historical events are unique in a nontrivial sense which entails the inapplicability of the Hempelian D-N model to historical explanations. Some previous criticisms of Hempel are shown to be general criticisms of the D-N model which can be outflanked in cases where a reduction to fundamental laws is available. I then survey grounds for denying that explanations by reasons can be effectively reduced to causal explanations, and for rejecting methodological individualism. I conclude with some positive remarks concerning the structure of historical explanations and sense in which historical events are unique.

Several writers have argued for the implausibility of there being naturalistic explanations of mystical experience. These writers recognize that the evidential significance of mystical experiences for theism depends upon whether explanations that exclude supernatural agency can be discounted; but they seem unaware of some of the best scientific work done in this area. Part I of the present paper introduces the theory of I. M. Lewis, an anthropologist, and tests it against the case of St Teresa. I use Teresa because of her prominence, and because we have considerable biographical data for her. I conclude that Lewis's approach, suitably supplemented, is strikingly successful in explaining this case.

Jerome Gellman has recently disputed my claim that a naturalistic explanation for mystical experiences is available, a better explanation than any current attempt to show that God is sometimes perceived in those experiences. Gellman argues (i) that some mystics do not 'fit' the sociological explanation of I. M. Lewis; (ii) that the sociological analysis of tribal mysticism cannot properly be extended to theistic experiences; and (iii) that mystical experiences merit prima facie credence, so the burden of proof falls on the naturalist. I reply (i) that the alleged counter-examples either do fit Lewis's explanation or are too poorly known to judge; (ii) that Lewis's theory, supplemented by recent neurophysiological findings, provides a strong explanation for all mystical experiences; and (iii) that the burden of proof, if there is one, now falls on the theist

Essentialism--understood as the doctrine that there are natural kinds--can be sustained with respect to the most fundamental physical entities of the world, as I elsewhere argue. In this paper I take up the question of the existence of natural kinds among complex structures built out of these elementary ones. I consider a number of objections to essentialism, in particular Locke's puzzle about the existence of borderline cases. A number of recent attempts to justify biological taxonomy are critically examined. I conclude that theory partially justifies such taxonomies but supports only a weaker form of essentialism
