was, together with other absolute Greek princes and some Republics, brought under the subjection of a Persian satrap in Asia Minor. Hermias was even sent as prisoner to Artaxerxes in Persia, and he at once caused him to be crucified. In order to avoid a similar fate, Aristotle fled with his wife Pythias, the daughter of Hermias, to Mitylene, and lived there for some time. He, however, erected a statue to Hermias in Delphi, with an inscription which has been preserved. From it we know that it was by cunning and treachery that he came under the power of the Persians. Aristotle also honoured his name in a beautiful hymn on Virtue, which has likewise come down to us.[80] From Mitylene he was (Ol. 109, 2; 343 B.C.) summoned by Philip of Macedon to undertake the education of Alexander, who was then fifteen years old. Philip had already invited him to do this in the well-known letter that he addressed to him just after Alexander’s birth: “Know that a son is born to me, but I thank the gods less that they have given him to me, than that they have caused him to be born in your time. For I hope that your care and your wisdom will make him worthy of me and of his future kingdom.”[81] It certainly would appear to be a brilliant historic destiny to be the instructor of an Alexander, and Aristotle at this court enjoyed the favour and esteem of Philip and of Olympias in the highest degree. What became of Aristotle’s pupil is known to all, and the greatness of Alexander’s mind and deeds, as also his enduring friendship, are the best witnesses of the success, as also of the spirit of this up-bringing, if Aristotle required such testimony. Alexander’s education utterly refuted the common talk about the practical uselessness of speculative philosophy. Aristotle had in Alexander another and worthier pupil than Plato found in Dionysius. Plato’s great interest was his Republic, the ideal of a state; he enters into relation with a person through whom it might be carried out; the individual was thus to him a medium only, and in so far indifferent to him. With Aristotle, on the other hand, this purpose was not present, he merely had the simple individual before him; and his end was to bring up and to develop the individuality as such. Aristotle is known to be a profound, thorough, and abstract metaphysician, and it is evident that he meant seriously with Alexander. That Aristotle did not follow with Alexander the ordinary superficial method of educating princes, might be confidently expected from the earnestness of one who well knew what was truth and true culture. It is also evident from the circumstance that Alexander, while in the midst of his conquests in the heart of Asia, when he heard that Aristotle had made known his acroamatic doctrines in speculative (metaphysical) writings, wrote him a reproachful letter, in which he said that he should not have made known to the common people what the two had worked out together.
