Abstract

The text at Phaedo 100a is a well-known crux: Socrates seems to claim as for his use of a hypothesis: whatever does not follow from my hypothesis, I put down as not true (hos ouk alethe). Since there may be pairs of contradictory propositions, both of which do not follow from his hypothesis, Socrates would have to claim that both are false, although of two contradictory propositions only one can be false. I argue, using a reading already proposed by Henricus Aristippus, that Plato had Socrates claim: (...) I do not put down as true (ouch hos alethe).
