Agassi, Interface 1 Philosophy of Science, Vol. 39, No. 2, June, 1972. pp 263 – 265. DISCUSSION REVIEW THE INTERFACE OF PHILOSOPHY AND PHYSICS • JOSEPH AGASSI Boston University These two volumes, : edited by Mario Bunge – one of the few avant-gardists in both physics and philo sophy – contain both stimulating and frustrating material. Some of the writers knowingly exert pressure on their readers (Clifford Truesdell); others flatter them by assuming that they know so much. The volumes are packed with material, and it takes a long time just to read them, let alone understand them. Had I known of anyone competent to understand these two volumes in all their aspects, I would have asked the editor to relieve me of my undertaking to review them. I could not read, for example, Jean Pierre Vigier, but merely gaze with astonishment at his few pages in which he geometrizes Lee algebras to get particles as warps in an Einsteinian universe of sorts, aiming to unify elementary particle theory, nuclear theory, etc., into one system – unfortunately with four spatial dimensions. This is not philosophy in any way, but straight high-powered speculative physics - which might, who knows, change everything, including philosophy. • Received September, 1969. : Mario Bunge, editor, Delaware Seminar In the Foundations of Physics, and Quantum Theory and Reality, Vols.
