I just had the following interesting exchange with my colleague Jack MacIntosh, in which every question was asked sincerely, and I have every reason to believe that Jack’s statements were true:
RZ: Zeno and Plato were contemporaries, right?
JM: Yes, for a while.
RZ: Did Plato retire before Aristotle began his studies?
JM: About Aristotle, I don’t know.
RZ: But Aristotle was never Plato’s student, right?
JM: No, he wasn’t. But Plato’s favorite historical figure–whom he worked on and gave classes on–was Plotinus.
