Particle Metaphysics

The empirical successes of atomic, nuclear, and particle physics have yet to banish from the metaphysical arena the controversies about the inner constitution of matter. This book examines these debates by exploring the particle concept in physics. Are the particles of modern physics "real" or are they virtual entities, their existence deduced merely by the careless application of abstract theories? Or are the philosophers involved in the debate about "scientific realism" dedicating themselves to a problem that has long been solved by physicists? Studies of the experimental basis and theoretical relevance of the particle concept reveal that these questions are far from easy to answer, because, ever since the introduction of quantum theory, physical science no longer possesses a consistent particle concept. All scientists and philosophers interested in the "true meaning" of such physical concepts will find this book informative and thought provoking.
