Synthetic: puts together that are separate already(eg. Necessary truth: something that could not possibly be false. First reversal, we can perhaps answer the question, by posing a hypothesis: P1: any x is teachable iff(pronounced if-if or if and only if, means the implication works both ways) x is knowledge. We are inclined to rely on it because it appears to be analytic (if the predicate is contained in the subject) 1st attempt: relied on the assumption that noone would ever want something bad intentionally (weak) - partial proof. 2nd attempt: wisdom is the common element.
