Jaegwon Kim is one of the most pre-eminent and most influential contributors to the philosophy of mind and metaphysics. This collection of essays presents the core of his work on supervenience and mind with two sets of postscripts especially written for the book. The essays focus on such issues as the nature of causation and events, what dependency relations other than causal relations connect facts and events, the analysis of supervenience, and the mind-body problem. A central problem in the philosophy of mind is the problem of explaining how the mind can causally influence bodily processes. Professor Kim explores this problem in detail, criticises the nonreductionist solution of it, and offers a modified reductionist solution of his own. Both professional philosophers and their graduate students will find this an invaluable collection.

Stephen Grimm finds me inclined to bifurcate epistemic assessment into higher and lower orders while showing awareness of this only in recent writings. Two untoward consequences allegedly follow: (a) my rejection of Virtue Reliabilism, and (b) my knowledge-based account of the value attaching to our knowledge on the higher level. By contrast, Grimm considers Virtue Reliabilism a perfectly adequate account of knowledge, while the higher epistemic state he believes to be, rather, understanding, which he takes to be quite distinct from knowledge. Once knowledge and understanding are seen to be distinct, finally, this will help us to avoid the two untoward consequences. I am grateful for these interesting points, and would like to respond briefly in what follows.

Ever since Plato, philosophers have faced one central question: what is the scope and nature of human knowledge? In this volume the distinguished philosopher Ernest Sosa collects essays on this subject written over a period of twenty-five years. All the major topics of contemporary epistemology are covered: the nature of propositional knowledge; externalism versus internalism; foundationalism versus coherentism; and the problem of the criterion. 'Sosa is one of the most prominent and most important epistemologists on the current American scene.' William P. Alston, Syracuse University.

According to nomological accounts of causation causal connections among events or states must be mediated by contingent laws of nature. Three types of causal connection are cited and discussed in opposition to such nomological accounts: (a) material causation (as when a zygote is generated by the union of an ovum and a sperm); (b) consequentialist causation (as when an apple is chromatically colored as a result of being red); (c) inclusive causation (as when a board is on a stump in consequence of its having been placed there by a carpenter). These are all source-consequence relations or result-yielding relations and they are all cases of necessitation, each with its own distinguishing features.

An intellectual virtue is a quality bound to help maximize one’s surplus of truth over error; or so let us assume for now, though a more just conception may include as desiderata also generality, coherence, and explanatory power, unless the value of these is itself explained as derivative from the character of their contribution precisely to one’s surplus of truth over error. This last is an issue I mention in order to lay it aside. Here we assume only a teleological conception of intellectual virtue, the relevant end being a proper relation to the truth, exact requirements of such propriety not here fully specified.

Life may turn sour and, in extremis, not worth living. On occasion it may be best, moreover, to lay down one's life for a greater cause. None of this is any news, debatable though it may remain, in general or case by case. Now comes the news that life does not matter in the way we had thought. No resurgence of existentialism, nor tidings from some ancient religion or some new cult, the news derives from the most sober and probing philosophical argument (the extraor- dinary Parfit, 1984, Part III), and takes more precisely the following form: Even though life L is optimal (in all dimensions), and even though if it were extended L would continue to be optimal, it does not follow that it is best to extend it, even for the subject whose life L is. What is the argument? Section II will defend a certain view of the nature of persons and personal identity, and Section III will then argue for the Paradox on that basis, and reflect on its philosophical implications and on the options it presents.
