For many years essentialism was considered beyond the pale in philosophy, a relic of discredited Aristotelianism. This is no longer so. Kripke and Putnam have made belief in essential natures respectable once more. Harré and Madden have argued against Hume's theory of causation and developed an alternative theory based on the assumption that there are genuine causal powers in nature. Dretske, Tooley, Armstrong, Swoyer, and Carroll have all developed strong alternatives to Hume's theory of the laws of nature. And Shoemaker (...) has developed a thoroughly non-Humean theory of properties. The "new essentialism" has evolved from these beginnings and can now reasonably claim to be a metaphysic for a modern scientific understanding of the world - one that challenges the conception of the world as comprising passive entities whose interactions are to be explained by appeal to contingent laws of nature externally imposed.

George Molnar came to see that the solution to a number of the problems of contemporary philosophy lay in the development of an alternative to Hume's metaphysics. This alternative would have real causal powers at its centre. Molnar set about developing a thorough account of powers that might persuade those who remained, perhaps unknowingly, in the grip of Humean assumptions. He succeeded in producing something both highly focused and at the same time wide-ranging. He showed both that the notion of (...) a power was central and that it could serve to dispel a number of long-standing philosophical problems.Molnar's account of powers is as realist as any that has so far appeared. He shows that dispositions are as real as any other properties. Specifically, they do not depend for their existence on their manifestations. Nevertheless, they are directed towards such manifestations. Molnar thus appropriates the notion of intentionality, from Brentano, and argues that it is the essential characteristic of powers. He offers a persuasive case for there being some basic and ungrounded powers, thus ruling out the reducibility of the dispositional to the non-dispositional. However, he does allow that there are non-power properties as well as power properties. In this respect, his final position is dualistic.This is contemporary metaphysics of the highest quality. It is a work that was almost complete when its author died. It has been edited for publication by another specialist in the subject, Stephen Mumford, who has also provided an introduction that will allow non-specialists to become acquainted with the issues. David Armstrong, one of the greatest living metaphysicians and personal friend of George Molnar, has provided a Foreword. (shrink)

This book is collection of the the author’s previously published papers on the philosophy of modality and tense and it also includes three unpublished papers. The author provides an exposition and defence of certain positions for which he is well-known: the intelligibility of modality de re; the primitiveness of the modal; and the primacy of the actual over the possible. He also argues for some less familiar positions: the existence of distinctive forms of natural and normative necessity, not reducible to (...) any form of metaphysical necessity; the need to make a distinction between the worldly and unworldly, analogous to the distinction between the tensed and the tenseless; and the viability of a nonstandard form of realism about tense, which recognizes the tensed character of reality without conceding there is any privileged standpoint from which it is to be viewed.

In his new foreword to this edition, Hilary Putnam forcefully rejects these nativist claims.

Professional philosophers and advanced students working in metaphysics and the philosophy of science will find this book both provocative and stimulating.

In ‘Finkish Dispositions’1 David Lewis proposes an analysis of dispositions which improves on the simple conditional analysis. In this paper I show that Lewis’ analysis still fails. I also argue that repairs are of no avail, and suggest why this is so.

This is a new release of the original 1949 edition.

In "The Philosophy of Nature," Brian Ellis provides a clear and forthright general summation of, and introduction to, the new essentialist position. Although the theory that the laws of nature are immanent in things, rather than imposed on them from without, is an ancient one, much recent work has been done to revive interest in essentialism and "The Philosophy of Nature" is a distinctive contribution to this lively current debate. Brian Ellis exposes the philosophical and scientific credentials of the prevailing (...) Humean metaphysic as less than compelling and makes the case for new essentialism as an alternative metaphysical perspective in lucid and unambiguous terms. This book develops this alternative metaphysic and considers the consequences for philosophy, and for some other areas of investigation, of working with such a metaphysic. Ellis argues that these consequences are profound and that a new essentialism provides a comprehensive new philosophy of nature for a modern scientific understanding of the world. (shrink)
