Alexander the Great:
Alexander to Aristotle, greeting. You have not done well to publish your books of oral doctrine; for what is there now that we excel others in, if those things which we have been particularly instructed in be laid open to all? For my part, I assure you, I had rather excel others in the knowledge of what is excellent, than in the extent of my power and dominion. Farewell.
It is also said that Aristotle was critical of Alexander for his deification, and calling himself a god.
They were both wrong.
