Philosophical Foundations of Quantum Theory¹

Abstract

THE development of physics in the last decades has repeatedly raised epistemological questions of fundamental importance. Thus in the theory of relativity the problem of space and time received at least a temporary clarification. New questions have arisen in connexion with the quantum theory, and particularly the question of the existence of causal laws in elementary physical processes. Is the condition of an atomic system completely determined, or are there gaps in its determination?
