One of the most difficult problems facing anyone who would discuss Professor Carl Hempel's thesis about explanation is the following: which of the many objections that have been made are actually relevant to the thesis ? Professor Hempel has claimed that several of these objections are not relevant at all ([1], pp. 412-414). In order to evaluate such replies, let me first state what I take to be the three claims which constitute Professor Hempel's thesis.
His first claim is that all adequate scientific explanations possess a certain property:
... all scientific explanations and their everyday counterparts claim or presuppose at least implicitly the deductive or inductive subsumability of whatever is to be explained under general laws or theoretical principles ([1], p. 425).
I should like to give acknowledgment to, and to thank, Professors Dray and Gorovitz, and especially this Journal's referee of my article, for both criticism and encouragement.
