Page "Aristotle" Paragraph 8

Near the end of Alexander's life, Alexander began to suspect plots against himself, and threatened Aristotle in letters.

Aristotle had made no secret of his contempt for Alexander's pretense of divinity, and the king had executed Aristotle's grandnephew Callisthenes as a traitor.

A widespread tradition in antiquity suspected Aristotle of playing a role in Alexander's death, but there is little evidence for this.
