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 on to defend the four-dimensionalist view from a criticism of it by Mellor, and finish with an account of the intuitive distinction between process and continuant terms.

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 concrete mass nouns

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 explanatory resources to explain why evident absurdities are absurd. A second objection is to the suggestion that cases involving artefacts can illustrate strong pluralism. This offends against the principle that gien a complex intrinsic microphysical property instantiated in some regiion, the number of material things possessing it in that region cannot depend on the existence and nature of intentional activity taking place outside it

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 have minds. Carruthers emphasizes arguments for and against the various theories considered, and encourages readers to actively evaluate these approaches as well. Written with clarity and directness, Introducing Persons will prove a useful text for the beginner while simultaneously providing original material of interest to the advanced student and professional philosopher.

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 difficulty, concerning the reference of ‘I’, can be met by distinguishing the thinker of an ‘I’‐thought from the reference of an ‘I’‐thought. The reference is always the person thinking the thought, but when the thought is simultaneously that of an animal coincident but non‐identical with that person, there is not a unique thinker. Mackie's criticisms of this view are ineffective.

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 that denying it is not so difficult, since its denial is an easy consequence of ordinary beliefs. I finish by explaining why van Inwagen has not persuaded me that it may be that artefacts do not exist and conclude that nothing stands in the way of tollensing van Inwagen and accepting the consequence of doing so

This new book offers a comprehensive and accessible introduction to Frege's remarkable philosophical work, examining the main areas of his writings and demonstrating the connections between them. Frege's main contribution to philosophy spans philosophical logic, the theory of meaning, mathematical logic and the philosophy of mathematics. The book clearly explains and assesses Frege's work in these areas, systematically examining his major concepts, and revealing the links between them. The emphasis is on Frege's highly influential work in philosophical logic and the theory of meaning, including the features of his logic, his conceptions of object, concept and function, and his seminal distinction between sense and reference. Frege will be invaluable for students of the philosophy of language, philosophical logic, and analytic philosophy

What are the requirements on an adequate genuine modal realist analysis of modal discourse? One is material adequacy: the modal realist must provide for each candidate analysandum an analysans in the language of counterpart theory which by his lights has the same truth value as the candidate analysandum. Must the material biconditional joining these be necessarily true? This is the requirement of strict adequacy. It is not satisfied if Lewis’s 1968 scheme provides the analysis. John Divers puts forward a modification, which identifies cases of ‘advanced modalizing’ in which the modal operator is semantically redundant. Even with this modification modal realist analyses of statements of modal discourse will be strictly inadequate. Strict adequacy can be achieved by extending the redundancy interpretation to all de dicto modal statements. The price is the denial of de dicto contingency. But perhaps material adequacy is enough. If the modal realist has a systematic means of replacing every sentence of quantified modal logic which he considers true by a sentence of counterpart theory that he considers true, perhaps he need do no more. Still, traditionally philosophical analysis aims at strict adequacy so it is as well to know that this is a test the modal realist analysis fails unless he abandons de dicto contingency

Debate between Humean contingentists and anti-Humean necessitarians in the philosophy of science is ongoing. One of the most important contemporary anti-Humeans is Alexander Bird. Bird calls the particular version of Humeanism he is opposed to 'categoricalism'. In his paper (2005) and in Chapter 4 of his book (2007) Bird argues against categoricalism about properties and laws. His arguments against categoricalism about properties are intended to support the necessitarian position he calls dispositional monism. His arguments against categoricalism about laws are intended to refute the contingent regularity view of laws (even in its sophisticated Lewisean version) and the nomic necessitation view of Armstrong (which involves a contingent necessitation relation). The general position Bird defends is that properties are necessarily related to the dispositions they bestow on their bearers and laws are necessary truths. I consider two of Bird's arguments against categoricalism about properties, and one of his arguments against the regularity view of laws. Maybe other arguments against categoricalism are persuasive. These, I submit, are not.
