 Insofar as Hempel focused on logically equivalent formulations of lawlike sentences in addressing the paradoxes of confirmation, some may find it remarkable that he does not explore the consequences of logically equivalent formulations in relation to explanations. We tend to assume we can explain why a specific thing \(c\) is black on the grounds that it is a raven and all ravens are black. Yet we would hesitate to explain why a specific thing is not a raven on the ground that it is not black. We may refer to this as the paradox of transposition. Notice, the contention that one member of a class of logically equivalent hypotheses is explanatory but others are not generates “paradoxes of explanation” that parallel the “paradoxes of confirmation” (Fetzer 2000a).
