Some formal ontological relations are identified, in the context of an account of ontological categorization. It is argued that neither formal ontological relations nor ontological categories should themselves be regarded as elements of being, but that this does not undermine the claim of formal ontology to be a purely objective science. It is also argued that some formal ontological relations, like some ontological categories, are more basic than others. A four‐category ontology is proposed, in which two basic categories of universals and two basic categories of particulars are distinguished in terms of certain formal ontological relations characteristically obtaining between entities belonging to the different categories

‘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

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.

Forms of thought are involved whenever we name, describe, or identify things, and whenever we distinguish between what is, might be, or must be the case. It appears to be a distinctive feature of human thought that we can have modal thoughts, about what might be possible or necessary, and conditional thoughts, about what would or might be the case if something else were the case. Even the simplest thoughts are structured like sentences, containing referential and predicative elements, and studying these structures is the main task of philosophical logic. This clear and accessible book investigates the forms of thought, drawing out and focusing on the central logical notions of reference, predication, identity, modality and conditionality. It will be useful to students and other interested readers in epistemology and metaphysics, philosophy of mind and language, and philosophical logic.

A self or person does not appear to be identifiable with his or her organic body, nor with any part of it, such as the brain; and yet selves seem to be agents, capable of bringing about physical events as causal consequences of certain of their conscious mental states. How is this possible in a universe in which, it appears, every physical event has a sufficient cause which is wholly physical? The answer is that this is possible if a certain kind of naturalistic dualism is true, according to which the conscious mental states of selves, although not identifiable with physical states of their brains, are emergent effects of prior physical causes. Moreover, mental causation on this model promises to explain certain aspects of physical behaviour which may appear arbitrary and coincidental from a purely physical point of view

The thesis of 3D/4D equivalence states that every three-dimensional description of the world is translatable without remainder into a four-dimensional description, and vice versa. In representing an object in 3D or in 4D terms we are giving alternative descriptions of one and the same thing, and debates over whether the ontology of the physical world is "really" 3D or 4D are pointless. The twins paradox is shown to rest, in relativistic 4D geometry, on a reversed law of triangle inequality. But considering the twins as 3D beings who age through time, the paradox implies that time passes at different rates in different reference frames, and therefore that the concept of a single global or Absolute time is unsustainable

John Locke (1632-1704) was one of the towering philosophers of the Enlightenment and arguably the greatest English philosopher. Many assumptions we now take for granted, about liberty, knowledge and government, come from Locke and his most influential works, _An Essay Concerning Human Understanding_ and _Two Treatises of Government_. In this superb introduction to Locke's thought, E.J. Lowe covers all the major aspects of his philosophy. Whilst sensitive to the seventeenth-century background to Locke's thought, he concentrates on introducing and assessing Locke in a contemporary philosophical setting, explaining why he is so important today. Beginning with a helpful overview of Locke's life and times, he explains how Locke challenged the idea that the human mind and knowledge of the external world rested on innate principles, laying the philosophical foundations of empiricism later taken up by Berkeley and Hume. Subsequent chapters introduce and critically assess topics fundamental to understanding Locke: his theories of substance and identity, language and meaning, philosophy of action and free will, and political freedom and toleration. In doing so, he explains some of the more complex yet pivotal aspects of Locke's thought, such as his theory that language rests on ideas and how Locke's theory of personal identity paved the way for modern empirical psychology. A final chapter assesses Locke's legacy, and the book includes a helpful chronology of Locke's life and glossary of unfamiliar terms.

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 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.

Truth depends in some sense on reality. But it is a rather delicate matter to spell this intuition out in a plausible and precise way. According to the theory of truth-making this intuition implies that either every truth or at least every truth of a certain class of truths has a so-called truth-maker, an entity whose existence accounts for truth. This book aims to provide several ways of assessing the correctness of this controversial claim. This book presents a detailed introduction to the theory of truth-making, which outlines truth-maker relations, the ontological category of truth-making entities, and the scope of a truth-maker theory. The essays brought together here represent the most important articles on truth-making in the last three decades as well as new essays by leading researchers in the field of the theory of truth and of truth-making

Non-Cartesian substance dualism maintains that persons or selves are distinct from their organic physical bodies and any parts of those bodies. It regards persons as ‘substances’ in their own right, but does not maintain that persons are necessarily separable from their bodies, in the sense of being capable of disembodied existence. In this paper, it is urged that NCSD is better equipped than either Cartesian dualism or standard forms of physicalism to explain the possibility of mental causation. A model of mental causation adopting the NCSD perspective is proposed which, it is argued, is consistent with all that is currently known about the operations of the human central nervous system, including the brain. Physicalism, by contrast, seems ill-equipped to explain the distinctively intentional or teleological character of mental causation, because it effectively reduces all such causation to ‘blind’ physical causation at a neurological level.

Eric T. Olson has argued that those who hold that two material objects can exactly coincide at a moment of time, with one of these objects constituting the other, face an insuperable difficulty in accounting for the alleged differences between the objects, such as their being of different kinds and possessing different persistence-conditions. The differences, he suggests, are inexplicable, given that the objects in question are composed of the same particles related in precisely the same way. In response, I show that the differences are not at all inexplicable once it is recognized that the conditions for a persisting object to be composed by certain particles at a moment of time must involve facts concerning other moments of time, and that the relevant facts are different for persisting objects of different kinds. Philosophers who neglect this sort of constraint on composition principles may be said to be victims of the 'cinematographic fallacy'
