Epistemology—at least for the bulk of its history—is primarily concerned with saying something useful, sensible, and general about this kind of knowledge. 4. The “analysis” of knowledge So far we’ve just said something about the kind of knowledge that philosophers are interested in.
But this assumption is not part of our folk epistemology. Central to our folk epistemology is the idea of epistemic agency: we do things to gain knowledge, to share knowledge, to conceal knowledge, bring about false belief and so on.
Now, epistemology is a big subject, and in one term we have to be selective. Our strategy will be to start with questions about what knowledge is, we’ll then move on to raise some issues about the justification of our beliefs, and how this has implications for thinking about the ‘structure’ of knowledge.
The second reason why philosophers have focused on propositional, factual, knowledge is that knowledge seems to have something to do with truth and with reasoning. Or, to put it another way, philosophers are interested in when, and how we get to discover the facts; they are interested in finding out the truth about things.
