The 8 ideas from 'Epistemology Naturalized'

You can't reduce epistemology to psychology, because that presupposes epistemology [Maund on Quine]
We should abandon a search for justification or foundations, and focus on how knowledge is acquired [Quine, by Davidson]
If we abandon justification and normativity in epistemology, we must also abandon knowledge [Kim on Quine]
Without normativity, naturalized epistemology isn't even about beliefs [Kim on Quine]
Mathematics reduces to set theory (which is a bit vague and unobvious), but not to logic proper [Quine]
Inculcations of meanings of words rests ultimately on sensory evidence [Quine]
Epistemology is a part of psychology, studying how our theories relate to our evidence [Quine]
In observation sentences, we could substitute community acceptance for analyticity [Quine]
