Hume's two definitions of causation have caused an extraordinary amount of controversy. The starting point for the controversy is the fact, well known to most philosophy undergraduates, that the two definitions aren't even extensionally equivalent, let alone semantically equivalent. So how can they both be definitions? One response to this problem has been to argue that Hume intends only the first as a genuine definition—an interpretation that delivers a straightforward regularity interpretation of Hume on causation. By many commentators' lights, however, this is a bug rather than a feature: such an account of the two definitions leaves necessary connection out of Hume's story about the meaning of "cause"..

_‘Informative, accessible, and fun to read— this is an excellent reference guide for undergraduates and anyone wanting an introduction to the fundamental issues of metaphysics. I know of no other resource like it.’– __Meghan Griffith, Davidson College, USA_ _'Marvellous! This book provides the very best place to start for students wanting to take the first step into understanding metaphysics.Undergraduates would do well to buy it and consult it regularly. The quality and clarity of the material are consistently high.' – __Chris Daly, University of Manchester, UK_ Ever wondered about Gunk, Brains in a Vat or Frankfurt’s Nefarious Neurosurgeon? With complete explanations of these terms and more, _Metaphysics: The Key Concepts_ is an accessible and engaging introduction to the most widely studied and challenging concepts in metaphysics. The authors clearly and lucidly define and discuss key terms and concepts, under the themes of: time particulars & universals realism & antirealism free will personal identity causation and laws. Arranged in an easy to use A-Z format, each concept is explored and illustrated with engaging and memorable examples, and accompanied by an up-to-date guide to further reading. Fully cross-referenced throughout, this remarkable reference guide is essential reading for students of philosophy and all those interested in the nature of reality.

Singularists about causation often claim that we can have experiences as of causation. This paper argues that regularity theorists need not deny that claim; hence the possibility of causal experience is no objection to regularity theories of causation. The fact that, according to a regularity theorist, causal experience requires background theory does not provide grounds for denying that it is genuine experience. The regularity theorist need not even deny that non-inferential perceptual knowledge of causation is possible, despite the fact that such knowledge would sometimes allow us to make inferences about what happens in far-off places and times.

The articles in this special issue of the yearbook Logical Analysis and History of Philosophy all concern, in one way or another, Hume’s epistemology and metaphysics. There are discussions of our knowledge of causal powers, the extent to which conceivability is a guide to modality, and testimony; there are also discussions of our ideas of space and time, the role in Hume’s thought of the psychological mechanism of ‘completing the union’, the role of impressions, and Hume’s argument against the claim that our perceptions are ‘locally conjoined’ with any entity (namely, a soul).

‘Natural kind essentialism’—here defined as the view that (i) the existence of natural kinds is a mind- and theory-independent matter, (ii) their essences are intrinsic, and (iii) they have a hierarchical structure—is commonly thought to be justified by appeal to Kripke–Putnam semantics, according to which propositions like ‘water is H20’ are necessary a posteriori. This chapter argues that the Kripke–Putnam semantics is in fact compatible with the denial of each of the three tenets of natural kind essentialism. The basic argument is that, assuming the range of natural kinds goes beyond those kinds for which we have vernacular names, deference to scientific theories is required in fixing the reference of natural kind terms. That those theories describe mind- and theory-independent reality, and that they do not admit a non-hierarchical structure for the categories they deploy, are theses that are independent of anything derivable from Kripke–Putnam semantics itself.

This collection brings together key contemporary texts in metaphysics and features an interactive commentary which helps readers engage the texts critically and to use them to develop their own views. Each text is followed by a detailed commentary, setting it in context Includes questions designed to help readers think hard about what the author is saying and why, to think of objections, and to formulate his or her own views Aims to improve the reader’s ability to engage critically with philosophical texts, and to use them as a springboard for philosophical thought and writing Introduces readers to the perennial problems of metaphysics and the ways that different analytic philosophers have approached them.

In a recent paper (Bird 2001), Alexander Bird argues that the law that common salt dissolves in water is metaphysically necessary - and he does so without presupposing dispositionalism about properties. If his argument were sound, it would thus show that at least one law of nature is meta- physically necessary, and it would do so without illicitly presupposing a position (dispositionalism) that is already committed to a necessitarian view of laws. I shall argue that Bird's argument is unsuccesful.

The paper considers whether psychiatric kinds can be natural kinds and concludes that they can. This depends, however, on a particular conception of ‘natural kind’. We briefly describe and reject two standard accounts – what we call the ‘stipulative account’ (according to which apparently a priori criteria, such as the possession of intrinsic essences, are laid down for natural kindhood) and the ‘Kripkean account’ (according to which the natural kinds are just those kinds that obey Kripkean semantics). We then rehearse a more permissive account: Richard Boyd’s ‘homeostatic property cluster’ (HPC) account. We argue that psychiatric kinds can in principle count as natural kinds on the HPC account. Moreover, specific psychiatric kinds (Tourette’s, schizophrenia, etc.) can be natural kinds even if the category psychiatric disorder is not itself a natural kind.

Humean compatibilism is the combination of a Humean position on laws of nature and the thesis that free will is compatible with determinism. This article's aim is to situate Humean compatibilism in the current debate among libertarians, traditional compatibilists, and semicompatibilists about free will. We argue that a Humean about laws can hold that there is a sense in which the laws of nature are 'up to us' and hence that the leading style of argument for incompatibilism?the consequence argument?has a false premiss. We also display some striking similarities between Humean compatibilism and libertarianism, an incompatibilist view. For example, standard libertarians face a problem about luck, and we show that Humean compatibilists face a very similar problem.
