When the Scientist turns Philosopher.

Abstract

This paper examines how such fundamental notions as causality and determinism have undergone changes as a direct result of empirical discoveries. Although such notions are often regarded as metaphysical, a priori concepts, experimental discoveries at the beginning of this century - radioactive decay, blackbody radiation and spontaneous emission - led to a direct questioning of the notions of causality and determinism. The experimental evidence suggested that these two notions must be separated. Causality and indeterminism were compatible with the behaviour of quantum-mechanical systems. The argument also sheds some light on the Duhem-Quine thesis, since experimental results at the periphery of the conceptual scheme directly affected conceptions at its very core.
