ABSTRACT
Professor Ducasse develops the thesis that every event of necessity must have a cause from which it follows in a uniform manner. If it can be shown that causality is both uniform and universal, determinism will ipso facto be proven'. Gale writes that 'the crucial question is whether this definition either includes or entails that causality is uniform'; and he then gives the reasons why he would answer that question in the negative. The contention is self-contradictory and therefore invalid, for it supposes that the requirements for causal necessitation of E in S, as these were defined, are strictly met, Gale's criticisms of the definition of Causality have put forward depends for such force as it has on certain considerations and distinctions too often neglected in discussions of Causality, which had therefore better first be explicitly stated.
