Locke notoriously included number amongst the primary qualities of bodies and was roundly criticized for doing so by Berkeley. Frege echoed some of Berkeley's criticisms in attacking the idea that ‘Number is a property of external things’, while defending his own view that number is a property of concepts. In the present paper, Locke's view is defended against the objections of Berkeley and Frege, and Frege's alternative view of number is criticized. More precisely, it is argued that numbers are assignable to pluralities of individuals. However, it is also argued that Locke went too far in asserting that ‘Number applies itself to ... everything that either doth exist, or can be imagined’.

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.

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.

In this book Jonathan Lowe offers a lucid and wide-ranging introduction to the philosophy of mind. Using a problem-centred approach designed to stimulate as well as instruct, he begins with a general examination of the mind-body problem and moves on to detailed examination of more specific philosophical issues concerning sensation, perception, thought and language, rationality, artificial intelligence, action, personal identity and self-knowledge. His discussion is notably broad in scope, and distinctive in giving equal attention to deep metaphysical questions concerning the mind and to the discoveries and theories of modern scientific psychology. It will be of interest to any reader with a basic grounding in modern philosophy.

When, for example, we say of something that it ‘is an object’, or ‘is an event’, or ‘is a property’, we are engaging in categorial predication: we are assigning something to a certain ontological category. Ontological categorization is clearly a type of classification, but it differs radically from the types of classification that are involved in the taxonomic practices of empirical sciences, as when a physicist says of a certain particle that it ‘is an electron’, or when a zoologist says of a certain animal that it ‘is a mammal’, or when a meteorologist says of a certain weather‐phenomenon that it ‘is a hurricane’. Classifications of the latter types presuppose that the items being classified have already been assigned to appropriate ontological categories, such as the categories of object, species, or event. What do categorial predications mean? How are their truth‐conditions to be determined, and how can those truth‐conditions be known to be satisfied? Do they have truthmakers? Questions like these are amongst those addressed in the present paper

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.

John Heil’s new book 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, 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.
