Extract

…the quantum theory of fields is the contemporary locus of metaphysical research. (Stein 1970, p. 285)

It is now generally recognized that Quantum Field Theory (QFT), after many vicissitudes and a period of almost total neglect, has emerged during the last ten years as a triumphant framework in which to do elementary particle physics.

If philosophers are prepared to use current physical theory as a guide to resolving metaphysical questions (and that is a big “If”), then QFT is what philosophers should all be studying. But the subject is notoriously.recondite, and philosophers are busy people, so the objective of the present paper is to cut through all technicalities and try to tell in as straightforward a way as possible just what QFT has to say about “reality”.
