The data that can bear on the confirmation of perceptual hypotheses includes, in the general case, considerably less than the organism may know.
Jerry FodorThere are lots of cases where we know more about how the world works than we do about how we know how it works. That's no paradox. Understanding the structure of galaxies is one thing, understanding how we understand the structure of galaxies is quite another. There isn't the slightest reason why the first should wait on the second and, in point of historical fact, it didn't. This bears a lot of emphasis; it turns up in philosophy practically everywhere you look.
Jerry FodorNo doubt, intuitions deserve respect. ...[but] I think that it is always up for grabs what an intuition is an intuition of. At a minimum, it is surely sometimes up for grabs.
Jerry Fodor...there are special sciences not because of the nature of our epistemic relation to the world, but because of the way the world is put together: not all natural kinds (not all the classes of things and events about which there are important, counterfactual supporting generalizations to make) are, or correspond to, physical natural kinds.
