123The Four-Dimensional WorldAnalysis 37 (1): 32-39. 1976.This paper defends the view of continuants as 'four-dimensional worms' against an argument of Geach's. This is to the effect that if continuants are four-dimensional worms then their stages either do, or do not, fall under the very general terms satisfied by the continuants themselves (a stage of a man either is, or is not, a man); but that either alternative is untenable. I try to show how the former alternative may be defended by appealing to some of Geach's own ideas about identity; then go o…Read more

220Count Nouns and Mass NounsAnalysis 38 (4): 167-172. 1978.The paper argues that one distinction between concrete count nouns and concrete mass nouns is that geach's derelativization thesis is valid for the former but not valid for the latter. That is, Where 'f' is a concrete count noun 'x is (an) f' means 'for some y, X is the same f as y', But where 'f' is a concrete mass noun this is not so; rather, In this case, 'x is f' is tantamount to 'for some y, X is the f of y'. It is further suggested that abstract nouns are in this respect to be grouped with…Read more

53Relative identity: a reply to Nicholas GriffinMind 89 (353): 96-98. 1980.In the October 1978 issue of Mind, Nicholas Griffin puts forward a criticism of one of my arguments in 'Wiggins on Identity'. Although I would not now wish to defend everything I said in that paper, the argument Griffin attacks still seems to me to be a good one. In what follows, I explain why I think his criticism fails to strike home.

84Against Strong PluralismPhilosophia 43 (4): 1081-1087. 2015.Strong pluralists hold that not even permanent material coincidence is enough for identity. Strong pluralism entails the possibility of purely material objects -- even if not coincident -- alike in all general respects, categorial and dispositional, relational and non-relational, past, present and future, at the microphysical level, but differing in some general modal, counterfactual or dispositional repscts at the macrophysical level. It is objectionable because it thus deprives us of the expla…Read more

121Tollensing van InwagenPhilosophia 42 (4): 1055-1061. 2014.Van Inwagen has an ingenious argument for the non-existence of human artefacts . But the argument cannot be accepted, since human artefacts are everywhere. However, it cannot be ignored. The proper response to it is to treat it as a refutation of its least plausible premise, i.e., to ‘tollens’ it. I first set out van Inwagen’s argument. I then identify its least plausible premise and explain the consequence of denying it, that is, the acceptance of a plenitudinous, pluralist ontology. I argue th…Read more

28Introducing PersonsPhilosophical Quarterly 38 (150): 123. 1988.This is an elegant and clear tour through many of the issues in philosophy of mind that have occupied philosophers of this century. The topics covered include the problem of other minds, arguments for and against the existence of the soul, a discussion of the bundle theory of the mind, behaviorism, functionalism, mind/brain identity, the argument against the possibility of private language, personal identity and the possibility of after-life, and the question of whether animals and computers can…Read more

31Animalism versus Lockeanism: Reply to MackiePhilosophical Quarterly 51 (202): 83-90. 2001.I respond to criticisms by David Mackie of my previous paper on animalism and Lockeanism. I argue that the ‘transplant intuition’, that a person goes where his brain (or cerebrum) goes, is compatible both with animalism and Lockeanism. I give three arguments for this conclusion, two of them developing lines of thought in Parfit's work. However, I accept that animalism and Lockeanism are incompatible, and I go on to consider the difficulties for Lockeanism that this raises. The principal difficu…Read more

291Constitution is identityMind 102 (405): 133-146. 1993.In his interesting article 'Constitution is not Identity' (1992), Mark Johnston argues that (in a sense soon to be explained) constitution is distinct from identity. In what follows, I dispute Johnston's contention.

142Objects and identity: an examination of the relative identity thesis and its consequencesMartinus Nijhoff. 1980.In the first twelve chapters of this book, I am concerned with the Fregean notion of an object (the reference of a proper name) and its connection with the notion of identity. The rest of the book is devoted to a discussion of the problem of personal identity.
