Abstract
Epistemological internalists have a problem about perceptual knowledge: how can perceptual experience both provide faithful information about the external world and justification for empirical belief? This is Sellars’s famous problem about “the given.” Chapter 12 argues, first, that this problem is not just for internalists—a version of it arises for naturalistic externalists. But, second, it argues that the problem can be solved within naturalistic bounds, by appealing to a category of causal relations called “intelligible causation.”
