To prevent possible misunderstanding, let me start from one crucial distinction between the logic of science on the one hand and the use of logic in science on the other. The very phrase "inference to the best theory" and the style of its further explication may suggest that it is the former that is at issue. In contrast, the title of the present workshop, "Induction and deduction in the sciences", suggests the latter to be its focus. And this I find to point to the more adequate way of thinking about the relation between logic and science. I do not believe in "the logic of science" as something that can possibly be read off science in a manner analogous to that of reading logic off mathematics: the classical logic off the classical mathematics or the intuitionistic logic off the intuitionistic mathematics.
