“I should like to propose a generalization; one which I fondly hope will some day come to be known as ‘Fodor’s First Law of the Nonexistence of Cognitive Science’. It goes like this: the more global (e.g. the more isotropic) a cognitive process is, the less anybody understands it” (Fodor, 1983, p. 107).

By saying that confirmation is isotropic, I mean that the facts relevant to the confirmation of a scientific hypothesis may be drawn from any- where in the eld of previously established empirical (or, of course, demonstrative) truths. Crudely: everything that the scientist knows is, in principle, relevant to determining what else he ought to believe. In principle , our botany constrains our astronomy, if only we could think of ways to make them connect. (Fodor, Modularity of Mind )
