On the Paradox of Confirmation

Abstract

This paper is devoted to analysis of co-called paradox of confirmation formulated by C. G. Hempel in the 1930s. In particular, the author proposes a solution of this puzzle. The proposal consists in refining the concept of confirmation by adding a clause that if A confirms a hypothesis h, the former must be a logical consequence of a latter, eventually derived with the help of additional assumptions. This leads to an additional constraint requiring that confirmations act relatively to sets of reference. Finally, if h and h’ are logically equivalent, a sentence A confirms both to the same degree if and only if related sets of reference are the same.
