Quantum field theory, one of the most rapidly developing areas of contemporary physics, is full of problems of great theoretical and philosophical interest. This collection of essays is the first systematic exploration of the nature and implications of quantum field theory. The contributors discuss quantum field theory from a wide variety of standpoints, exploring in detail its mathematical structure and metaphysical and methodological implications.

The vacuum is fast emerging as the central structure of modern physics. This collection brings together philosophically-minded specialists who engage these issues in the context of classical gravity, quantum electrodynamics, and the grand unification program. The vacuum emerges as the synthesis of concepts of space, time, and matter; in the context of relativity and the quantum this new synthesis represents a structure of the most intricate and novel complexity. This book is a work in modern metaphysics, in which the concepts of substance and space interweave in the most intangible of forms,...

It is not widely known that Einstein had doubts, increasing with time, about the way he formulated his special theory of relativity in 1905. Physical Relativity examines the grounds of these doubts and related misgivings on the part of a handful of physicists and philosophers in the course of the twentieth century. Harvey Brown defends an interpretation of relativity theory, and hence of the nature of space and time, that combines Einstein's insights with those of his immediate precursors, who today are widely regarded as having had the right ideas for the wrong reasons. Appearing in the...
