Document Summary
Necessary contingent: rationalists (e. g. plato, descrates) versus empiricists. Put aside for sake of finding out whether something is. Iff if and only if; sometimes read ifif right: knowledge is analytic".

P1 any x is teachable iff x is knowledge. Modus tollens: no teachers, no knowledge: previous conclusion is turned into a reductio. Some people claim to be teachers as they give highly paid lectures to on important topics". In the ancient world these people were sophists. Sophists gave bad, fallacious but clever arguments. They taught pupils how to make arguments that if you only heard it once would convince you. (like lawyers maybe? very persuasive) So, they aren"t really teachers are virtue.
