 By similar reasoning, if “Socrates” meant the teacher of Plato and Xenophon, it would be a priori that Socrates taught Plato (Kripke 1980: 65). However, unlike the proposition that bachelors are unmarried, this claim does not seem to be a priori. Intuitively speaking, the widely held belief that Socrates taught Plato could turn out to be false. Perhaps one day documents will come to light establishing that the person who served as a model for the character of Socrates in Plato’s dialogues (and other similar traditions) lived out his life prior to Plato’s birth. Such evidence would appear to refute the tradition according to which Plato was Socrates’ pupil.
