Aristotle had, at this time, reached the most prosperous period of his life. The founder and leader of the principal school of Greece, and the undisputed head of Grecian philosophy, surrounded by his numerous disciples and admirers, protected by the conqueror of Asia, and by him furnished with the means of following his favorite pursuits, and of gratifying his universal spirit of inquiry, he had, probably, little to desire in order to fill up the measure of a philosopher’s ambition. But he did not continue to enjoy the favor of Alexander till the end. Callisthenes, by his free-spoken censures and uncourtly habits, had offended his master, and had been executed, on a charge of having conspired with some Macedonians to take away his life; and the king’s wrath appears to have extended to his kinsman, Aristotle, as being the person who had originally recommended him. It is not, however, probable that this circumstance caused any active enmity between the royal pupil and his master; even if we did not know that Alexander died a natural death, there would be no reason for listening to the absurd calumny that Aristotle was concerned in poisoning him. Aristotle indeed appears to have been considered, to the last, as a partisan of Alexander, and an opponent of the democratic interest. When the anti-Macedonian party obtained the superiority at Athens in consequence of Alexander’s death, an accusation against Aristotle was immediately prepared, and the pretext selected, was, as in the case of Socrates, _impiety_, or _blasphemy_. He was charged by Eurymedon, the priest, and a man named Demophilus, probably a leader of the popular party, with paying divine honors to Hermeias, and perhaps with teaching certain irreligious doctrines. In order to escape this danger, and to prevent the Athenians, as he said, in allusion to the death of Socrates, from “sinning twice against philosophy,” he quitted Athens in the beginning of the year 322 B. C., and took refuge at Chalcis, in Euboea, an island then under the Macedonian influence—leaving Theophrastus his successor in the Lyceum. There he died, of a disease of the stomach, in the autumn of the same year, being in the sixty-third year of his age. His frame is said to have been slender and weakly, and his health had given way in the latter part of his life, having probably been impaired by his unwearied studies and the intense application of his mind. The story of his having drowned himself in the Euripus of Euboea, is fabulous.
