In 347 Plato died, leaving his nephew Speusippus to succeed him in the headship of the Academy. Aristotle then left Athens, accompanied by another Platonist, Xenocrates, a circumstance tending to prove that his relations with the school continued to be of a cordial character. The two settled in Atarneus, at the invitation of its tyrant Hermeias, an old fellow-student from the Academy. Hermeias was a eunuch who had risen from the position of a slave to that of vizier, and then, after his master’s death, to the possession of supreme power. Three years subsequently a still more abrupt turn of fortune brought his adventurous career to a close. Like Polycrates, he was treacherously seized and crucified by order of the Persian Government. Aristotle, who had married Pythias, his deceased patron’s niece, fled with her to Mitylênê. Always grateful, and singularly enthusiastic in his attachments, he celebrated the memory of Hermeias in a manner which gave great offence to the religious sentiment of Hellas, by dedicating a statue to him at Delphi, and composing an elegy, still extant, in which he compares the eunuch-despot to Heracles, the Dioscuri, Achilles, and Ajax; and promises him immortality from the Muses in honour of Xenian Zeus. When we next hear of Aristotle he is at the Macedonian Court,[174] acting as tutor to Alexander, the future conqueror of Asia, who remained under his charge between the ages of thirteen and sixteen years. The philosopher is more likely to have obtained this appointment by Court interest—his father was Court-physician to Alexander’s grandfather, Amyntas—than by his reputation, which could hardly have been made until several years afterwards. Much has been made of a connexion which, although it did not last very long, appeals strongly to the imagination, and opens a large field for surmise. The greatest speculative and the greatest practical genius of that age—some might say of all ages—could not, one would think, come into such close contact without leaving a deep impression on each other. Accordingly, the philosopher is supposed to have prepared the hero for his future destinies. Milton has told us how Aristotle ‘bred great Alexander to subdue the world.’ Hegel tells us that this was done by giving him the consciousness of himself, the full assurance of his own powers; for which purpose, it seems, the infinite daring of thought was required; and he observes that the result is a refutation of the silly talk about the practical inutility of philosophy.[175] It would be unfortunate if philosophy had no better testimonial to show for herself than the character of Alexander. It is not the least merit of Grote’s History to have brought out in full relief the savage traits by which his conduct was marked from first to last. Arrogant, drunken, cruel, vindictive, and grossly superstitious, he united the vices of a Highland chieftain to the frenzy of an Oriental despot. No man ever stood further from
