Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

This book, one of the first full-length studies of the modalities to emerge from the debate to which Saul Kripke, David Lewis, Ruth Marcus, and others are contributing, is an exploration and defense of the notion of modality de re, the idea that objects have both essential and accidental properties. Plantinga develops his argument by means of the notion of possible worlds and ranges over such key problems as the nature of essence, transworld identity, negative existential propositions, and the existence (...) of unactual objects in other possible worlds. He also applies his logical theories to the elucidation of two problems in the philosophy of religion: the problem of evil and the ontological argument. (shrink)

This is the second volume of philosophical essays by one of the most innovative and influential philosophers now writing in English. Containing thirteen papers in all, the book includes both new essays and previously published papers, some of them with extensive new postscripts reflecting Lewis's current thinking. The papers in Volume II focus on causation and several other closely related topics, including counterfactual and indicative conditionals, the direction of time, subjective and objective probability, causation, explanation, perception, free will, and rational (...) decision. Throughout, Lewis analyzes global features of the world in such a way as to show that they might turn out to supervene on the spatiotemporal arrangement of local qualities. (shrink)

_Naming and Necessity_ has had a great and increasing influence. It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of naming, and of identity. This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here reissued in a newly corrected form with a new preface by the author. If there is such a thing as essential reading in metaphysics, or in philosophy of language, this is (...) it. (shrink)

The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. 'Parts could easily be the standard book on mereology for the next twenty (...) or thirty years.' Timothy Williamson, Grazer Philosophische Studien. (shrink)

Thinking about space is thinking about spatial things. The table is on the carpet; hence the carpet is under the table. The vase is in the box; hence the box is not in the vase. But what does it mean for an object to be somewhere? How are objects tied to the space they occupy? This book is concerned with these and other fundamental issues in the philosophy of spatial representation. Our starting point is an analysis of the interplay between (...) mereology (the study of part/whole relations), topology (the study of spatial continuity and compactness), and the theory of spatial location proper. This leads to a unified framework for spatial representation understood quite broadly as a theory of the representation of spatial entities. The framework is then tested against some classical metaphysical questions such as: Are parts essential to their wholes? Is spatial colocation a sufficient criterion of identity? What (if anything) distinguishes material objects from events and other spatial entities? The concluding chapters deal with applications to topics as diverse as the logical analysis of movement and the semantics of maps. (shrink)

The author expounds critically Roderick Chisholm's theory of modal mereology and undertakes to redeploy and reconcile this with the Lesniewski-Tarski theory of part-whole, modally augmented. An argument is presented for the principle that what belongs to an aggregate as a part belongs essentially to it. This principle is argued not to imply that every part of an ordinary substance is essentially part of it (such substances not being aggregates), and to give no particular support to Roderick Chisholm's postulation of entia (...) successiva in substitution for ships, trees, and houses as ordinary conceived. Entia successiva are not good candidates for identification with these. (shrink)

This note criticizes Andrew Brennan's attempt to defend best?candidate theories of the identity of artefacts over time against certain now familiar objections. Adoption of a mereological conception of individuals does not, in itself, provide the means for a satisfactory response to objections of Wiggins and Noonan (some of which are anyway ill?focused). The way forward consists in recognizing that the consequences of best?candidate theories which have been thought objectionable (in particular, commitment to the extrinsicness of identity) do not violate the (...) necessity of identity and imply ? what anyway ought to seem unexceptionable ? that a predicate such as ?constituting the ship which is the Ship of Theseus? does not denote a genuine property of the hunk of matter of which the predicate is true. Once these consequences have been clearly mapped out, the best?candidate theorist's commitment to the extrinsicness of identity does not appear absurd. (shrink)
