Knowledge isn't truth.

That seems at best trivially true, in that "knowledge is truth" seems to be committing a category mistake. A common-enough epistemological position is that knowledge is about true propositions.

More specifically, many in epistemology will define knowledge as "justified true belief". So by this way of thinking, if "S knows X" is true, then X is true.

Nobody defines knowledge simply as justified true belief anymore. Everybody needs a workaround for Gettier cases.

Well, while I agree with your sentiment, surely your statement is technically false. Indeed, one way to get around Gettier cases is to simply make "justified" a more difficult credential to obtain (not that I think that's a good solution).

Also, many philosophers no longer think definitions need to specify necessary or sufficient conditions, and so would happily claim 'justified true belief' is a 'good enough' definition of knowledge.

I'm probably overgeneralizing from the professors I've had. Your point is well taken.
