During all the years in which Aristotle was thus engaged, his position at Athens was becoming more and more insecure. The anti-Macedonian party were waiting for the first opportunity to rid the city of him, and were prevented from open attempts at this only by dread of Alexander's displeasure. Even when it was known that Aristotle had incurred disfavor with his old pupil, they did not venture to attack him; but in 323, when the news of Alexander's sudden death made all Greece feel that now the time had come to get rid forever of the hated Macedonians, and recover its liberty, they at once gave vent to their long-cherished hatred. How hard it was to find matter for an accusation against him, is shown by the fact that they had to go back to his old poem on _Worth_, written in memory of Hermias (see p. 4), and to base thereon a charge of impiety--a charge always easily made, and always sure to arouse strong popular prejudice. According to Athenian law, the defendant in any such case might, if he chose, escape punishment by leaving the city any time before the trial; and Aristotle, not being, like Socrates, a citizen, could have no ground for refusing to take advantage of this liberty. Accordingly, with the remark that he would not voluntarily allow the Athenians to sin a second time against philosophy, he withdrew to his country residence at Chalcis in Eubœa, the old home of his mother's family, to wait till affairs should take another turn, as, indeed, they soon afterwards did, when Athens had to open her gates to Antipater. But, ere that happened, Aristotle was in his grave, having died in 322, shortly before Demosthenes, of disease of the stomach, from which he had long suffered. His remains are said to have been carried to Stagira, where the grateful inhabitants erected an altar over them and paid divine honors to his memory. His library and the manuscripts of his works he left in the hands of Theophrastus, who succeeded him in the Lyceum. His will, the text of which has come down to us, bears testimony, along with all else that we know of him, to the nobility, kindliness, and justice of his nature. CHAPTER II ARISTOTLE'S PHILOSOPHY Platon rêvait; Aristote pensait.--Alfred de Musset. Are God and Nature then at strife That Nature lends such evil dreams? --Tennyson. There are three Essences. Two of these are sensible; one being eternal, and the other perishable. The latter is admitted by all, in the form, for example, of plants and animals; in regard to the former, or eternal one, we shall have to consider its elements, and see whether they be one or many. The third is immutable [and, therefore, inaccessible to sense], and this some thinkers hold to be transcendent.--Aristotle.
