This book revives a neglected but important topic in philosophy: the nature of substance. The belief that there are individual substances, for example, material objects and persons, is at the core of our common-sense view of the world yet many metaphysicians deny the very coherence of the concept of substance. The authors develop an account of what an individual substance is in terms of independence from other beings. In the process many other important ontological categories are explored: property, event, space, (...) time. The authors show why alternative theories of substance fail, and go on to defend the intelligibility of interacting spiritual and material substances. (shrink)
This paper examines an often-ignored aspect of the evaluation of metaphysical analyses, namely, their ontological commitments. Such evaluations are part of metaphysical methodology, and reflection on this methodology is itself part of metametaphysics. I will develop a theory for assessing what these commitments are, and then I will apply it to an important historical and an important contemporary metaphysical analysis of the concept of an individual substance (i.e., an object, or thing). I claim that in evaluating metaphysical analyses, we should (...) not only rule out counterexamples, but also compare them with respect to their ontological commitments, and we should hold that if they are comparable in other respects, then an analysis with fewer such commitments is preferable to one with more (There is, of course, a connection between counterexamples and ontological commitments. If the existence or possible existence of something one is committed to the existence or possible existence of is incompatible with an analysis, then one should reject that analysis as inadequate to the data. On the other hand, if one is uncertain about the existence or possible existence of something that is incompatible with an analysis, then while this does not refute the analysis for one, it raises doubts about it. The fewer such doubts are raised by an analysis, the better it is.). (shrink)
Substance has been a leading idea in the history of Western philosophy. _Joshua Hoffman and Gary S. Rosenkrantz_ explain the nature and existence of individual substances, including both living things and inanimate objects. Specifically written for students new to this important and often complex subject, _Substance_ provides both the historical and contemporary overview of the debate. Great Philosophers of the past, such as Aristotle, Descartes, Spinoza, Leibnitz, Locke, and Berkeley were profoundly interested in the concept of substance. And, the authors (...) argue, a belief in the existence of substances is an integral part of our everyday world view. But what constitutes substance? Was Aristotle right to suggest that artefacts like tables and ships don't really exist? _Substance: Its Nature and Existence_ is one of the first non-technical, accessible guides to this central problem and will be of great use to students of metaphysics and philosophy.

Certain philosophers have attacked the problem of defining omnipotence by arguing that the following provides at least the core of a successful definition: x is omnipotent = df..In Dl, x ranges over agents and s over states of affairs.Despite the intuitive plausibility of Dl, it has been argued that certain conjunctive states of affairs provide counterexamples to Dl, for example: A ball moves at t and no omnipotent agent brings it about that a ball moves at t.First, we show that (...) if states of affairs like si are genuine counterexamples to Dl, then certain strategies which have been employed in the literature to provide an analysis along the lines of Dl do not succeed. Second, we argue that despite appearances, states of affairs like si are not genuine counterexamples to Dl. (shrink)
