Argentine physicist and science-philosopher Mario Bunge was born in Buenos Aires in 1919. Today he is professor at the McGill University in Montreal, where he holds the Frothingham Chair of logic and metaphysics (he is Frothingham Professor of Logic and Metaphysics). He has also been visiting professor at numerous universities in America and Europe. Bunge assigned to the philosophy of science the fundamental task of demonstrating the general principles and philosophical categories that support all scientific research. Such research should lead to the development of ‘exact metaphysics’ instruments of investigation, which would consist of logic, mathematics and formal semantics. Bunge is particularly interested in the philosophy of physics and the problems arising related to quantum mechanics.
