The twenty-sixth volume in the highly acclaimed Library of Living Philosophers series is devoted to the work of British philosopher of logic and metaphysician, P. F. Strawson. Following the Library of Living Philosophers series format, the volume contains an intellectual autobiography, twenty critical and descriptive essays by leading philosophers from around the world, Strawson's replies to the essays, and a bibliography of Strawson's works. Born in 1919, Strawson was a leading proponent of ordinary language philosophy. He is the author of (...) the early and extremely influential paper "On Referring" in which he criticized Russell's theory of definite descriptions. His most influential book, Individuals, helped to raise the status of metaphysics as a philosophical enterprise. Themes first addressed in this book continued to be of concern to him in his later work, including the possibility of objective knowledge, the subject-predicate distinction, the ontological status of persons, and the problem of individuation. Contributors to the book include: Ruth Garrett Millikan, Susan Haack, E. M. Adams, Panayot Butchvarov, Richard Behling, John McDowell, Simon Blackburn, Tadeusz Szubka, David Frederick Haight, Joseph S. Wu, Andrew G. Black, David Pears, Robert Boyd, Hilary Putnam, Paul F. Snowdon, Arindam Chakrabarti, Wenceslao J. Gonzalez, Ernest Sosa, Chung-M. Tse, John R. Searle, P. F. Strawson. (shrink)

In the modal literature various notions of completeness have been studied for normal modal logics. Four of these are defined here, viz. (plain) completeness, first-order completeness, canonicity and possession of the finite model property — and their connections are studied. Up to one important exception, all possible inclusion relations are either proved or disproved. Hopefully, this helps to establish some order in the jungle of concepts concerning modal logics. In the course of the exposition, the interesting properties of first-order definability (...) and preservation under ultrafilter extensions are introduced and studied as well. (shrink)

Avez-vous remarqué que dans le monde tout ce qui compte va par quatre? La musique : timbre, harmonie, rythme et mélodie. Le repérage : altitude, latitude, longitude et datation. Les quatre aspects de la cause: pour quoi, avec quoi, par quoi et selon quoi? Les forces de la nature : interactions faible, forte, électromagnétique et gravitationnelle... Les vingt-quatre particules élémentaires qui constituent la matière une famille de six leptons associée à trois familles de quarks. Et aussi la logique d'un discours (...) nuancé : oui, non, oui et non, ni oui ni non. Pourquoi quatre est-il partout? La notion de quaternité apporte une réponse à la fois simple et surprenante à cette question. A partir d'exemples tirés de l'expérience humaine, les auteurs en dégagent les aspects structurels et s'en servent pour approfondir le sens des mathématiques et de divers autres domaines liés à la genèse de la connaissance. Il s'agit d'une nouvelle épistémologie, fondée sur un modèle logique qui complète celui d'Aristote. (shrink)
