It is well known that many of the founding fathers of quantum mechanics - Einstein, Schrödinger, de Broglie etc. - were not satisfied with the final formulation of the theory. In particular the currently fashionable phenomenon of entanglement has attracted several criticisms. John Bell was able to formulate an inequality in the Sixties that could experimentally discriminate between orthodox quantum mechanics and locality. In the Seventies and the Eighties many experiments seemed to favor the standard theory. Thereafter a long and animated debate developed concerning both the epistemology and the ontology of microphysical reality. Starting from the Thirties, Italy has been one of the leading countries in the development of physics, as well as in the study of its theoretical foundations and philosophical implications.
Gino Tarozzi has long been and still is one of the best Italian scholars in the field. The present volume collects several valuable contributions touching upon different philosophical problems, such as entanglement, realism, causality, quantum logic and many others. In the occasion of Tarozzi's 60th birthday many distinguished scholars, which collaborate with him, evaluate and discuss these topics. All papers are original and together they give a global and detailed image concerning both the foundations and the philosophical implications of quantum physics.

Vincenzo Fano teaches philosophy of science at the Urbino University, where is presently head of the School of philosophy of knowledge. He published several books and more than one hundred papers on philosophy of physics, philosophy of psychology and epistemology of natural sciences. His last volume is on Zeno's paradoxes and modern science. Fano is also permanent member of the Académie Internationale de Philosophie des Sciences.
