Well, "obviously" everything that I know must be truth; otherwise it would be mere belief. But for everything I think I know, there's someone that believes different. In that light, it seems unreasonable for anyone to think they have access to truth.
So truth seems to be reduced (or elevated?) to something we can never reach, and only aspire to. It makes it into some kind of metaphysical object, whose nature can't be empirically established.
I think it's best to avoid talking about truth, when trying to do philosophy. Just do the reasoning, and draw some conclusions if you can.
Yes, let's throw all of epistemology into the trash
Epistemology is theory of knowledge; it's a statement in epistemology (one which you might disagree with) that knowledge and truth are not the same thimg.
