‘Water is H2O’ is one of the most frequently cited sentences in analytic philosophy, thanks to the seminal work of Saul Kripke and Hilary Putnam in the 1970s on the semantics of natural kind terms. Both of these philosophers owe an intellectual debt to the empiricist metaphysics of John Locke's Essay Concerning Human Understanding, while disagreeing profoundly with Locke about the reality of natural kinds. Locke employs an intriguing example involving water to support his view that kinds (or ‘species’), such as water and gold, are the workmanship of the human mind. This is the point of his story about a winter visitor to England from Jamaica, who is astonished to find that the water in his basin has turned solid overnight, and proceeds to call it ‘hardened water’. Locke criticizes this judgement, maintaining that it is more consonant with common sense to regard water and ice as different kinds of substance. Putnam, by implication, disagrees. Deploying his imaginary example of Twin Earth—a distant planet where a watery-looking substance, XYZ, rather than H2O, fills the oceans and rivers—he maintains that common sense supports the judgement that XYZ and H2O, despite their superficial similarity, are not the same kind of substance, precisely because their molecular compositions are different. Here it will be argued that both views are mistaken, but that, in this dispute, Locke has more right on his side than his modern opponents do

Le réalisme métaphysique est la conception suivant laquelle la plupart des objets qui peuplent le monde existent indépendamment de notre pensée et possèdent une nature indépendante de la manière dont nous pouvons éventuellement la concevoir. A mon sens cette position engage à admettre une forme robuste d'essentialisme. Beaucoup des formes modernes de l'anti-réalisme tirent leurs origines d'une forme de conceptualisme, suivant laquelle toutes les vérités que nous puissions connaître au sujet des essences sont en dernière analyse fondées sur nos concepts, plutôt que dans les choses « en elles-mêmes ». Mon but est de montrer que l'anti-réalisme conceptualiste est une doctrine incohérente, et comment nous pouvons soutenir le réalisme métaphysique et l'essentialisme robuste, tout en reconnaissant clairement le rôle cognitif des concepts en tant qu'intermédiaires dans notre appréhension de la nature de la réalité indépendante de l'esprit.

A systematic overview of modern metaphysics, A Survey of Metaphysics covers all of the most important topics in the field. It adopts the fairly traditional conception of metaphysics as a subject that deals with the deepest questions that can be raised concerning the fundamental structure of reality as a whole. The book is divided into six main sections that address the following themes: identity and change, necessity and essence, causation, agency and events, space and time, and universals and particulars. It focuses on contemporary views and issues throughout, rather than on the history of metaphysics.

In this paper, it is argued that metaphysics, conceived as an inquiry into the ultimate nature of mind-independent reality, is a rationally indispensable intellectual discipline, with the a priori science of formal ontology at its heart. It is maintained that formal ontology, properly understood, is not a mere exercise in conceptual analysis, because its primary objective is a normative one, being nothing less than the attempt to grasp adequately the essences of things, both actual and possible, with a view to understanding as far as we can the fundamental structure of reality as a whole. Accordingly, it is urged, the deliverances of formal ontology have a modal and epistemic status akin to those of other a priori sciences, such as mathematics and logic, rather than constituting rivals to the claims of the empirical sciences, such as physics.

Locke on Human Understanding, is a comprehensive introduction to John Locke's major work, Essay Concerning Human Understanding . Locke's Essay remains a key work in many philosophical fields, notably in epistemology, metaphysics and the philosophies of mind and language. In addition, Locke is often referred to as the first English empiricist. Knowledge of this influential work and figure is essential to Enlightenment thought. E. J. Lowe's approach enables students to effectively study the Essay by placing Locke's life and works in their intellectual and historical context. The book provides a critical examination of the leading themes in the Essay , illuminating the main lines in Locke's thinking. Such topics include innate ideas, perception, primary and secondary qualities, personal identity, free will, action and language. Finally, E. J. Lowe examines the comtemporary work being done on this highly influential English philosopher.

John Heil's new book (Heil 2003) is remarkable in many ways. In a concise, lucid and accessible manner, it develops a complete system of ontology with many strikingly original features and then applies that ontology to fundamental issues in the philosophy of mind, with illuminating results. Although Heil acknowledges his intellectual debts to C. B. Martin (p. viii), he is unduly modest about his own contribution to the development and application of this novel metaphysical system. A full examination of the position that Heil defends would require a book in itself, so I shall limit myself to discussing some of its central themes and to explaining a few doubts that I have concerning some aspects of it.

Jonathan Lowe argues that metaphysics should be restored to a central position in philosophy, as the most fundamental form of inquiry, whose findings underpin those of all other disciplines. He portrays metaphysics as charting the possibilities of existence, by identifying the categories of being and the relations between them. He sets out his own original metaphysical system, within which he seeks to answer many of the deepest questions in philosophy. 'a very rich book... deserves to be read carefully by anyone interested in any of the many subjects he discusses.' Katherine Hawley, British Journal of the Philosophy of Science.

How could the self be a substance? There are various ways in which it could be, some familiar from the history of philosophy. I shall be rejecting these more familiar substantivalist approaches, but also the non-substantival theories traditionally opposed to them. I believe that the self is indeed a substance—in fact, that it is a simple or noncomposite substance—and, perhaps more remarkably still, that selves are, in a sense, self-creating substances. Of course, if one thinks of the notion of substance as an outmoded relic of prescientific metaphysics—as the notion of some kind of basic and perhaps ineffablestuff—then the suggestion that the self (or indeed anything) is a substance may appear derisory. Even what we ordinarilycall‘stuffs’—gold and water and butter and the like—are, it seems, more properly conceived of as aggregates of molecules or atoms, while the latter are not appropriately to be thought of as being ‘made’ of any kind of ‘stuff’ at all. But this only goes to show that we need to think in terms of a more sophisticated notion of substance—one which may ultimately be traced back to Aristotle's conception of a ‘primary substance’ in theCategories, and whose heir in modern times is W. E. Johnson's notion of the ‘continuant’. It is the notion, that is, of a concrete individual capable of persisting identically through qualitative change, a subject of alterable predicates that is not itself predicable of any further subject.
