ARISTOTLE . 55 pursue the study of philosophy. He was then in his eighteenth year. For twenty years he studied in the academy under Plato, and as he had spent all his inheritance, he was induced, in order to procure a subsistence, to vend medicines at Athens. Aristotle ate little and slept less. So strong was his passion for study, that in order to resist the oppression of sleep, he kept at his bedside a brazen basin, over which when in bed, he stretched one of his hands in which he held an iron ball, that if he should fall asleep, the noise of the ball dropping into the basin might awake him instantly. According to Laertius his voice was shrill and squeaking, his eyes small, his legs slenddfr, and he dressed magnificently. Aristotle was a man of acute parts, and one who easily comprehended the most difficult questions. He soon became master of the doctrines of Plato, and distinguished himself among the other academicians. No question was decided in the academy without the opinion of Aristotle, though it was often subversive of that of Plato. By all his fellow-students he was considered as a prodigy of genius, and his opinions were often followed, in opposition to those of his master. Aristotle left the academy. This excited the resentment of Plato. He could not refrain from treating him as a rebel, comparing him to the chick which pecks its dam. The Athenians appointed him ambassador to Philip, king of Macedonia, father of Alexander the Great. Aristotle, having spent some time in Mace- donia in settling the affairs of the Athenians, found, upon his return, that Xen- ocrates had been chosen master of the academy. Seeing that place thus filled he said, " It would be a shame for me to be silent, when Xenocrates speaks." He accordingly established a new sect, and taught doctrines different from those of his master Plato. The celebrity of Aristotle, who now surpassed all his contemporaries in every kind of science, especially in the departments of philosophy and politics, induced Philip, king of Macedonia, to offer him the care of the education of his son Alex- ander, then fourteen years of age. Aristotle accepted. He continued Alex- ander's preceptor for eight years ; and according to the testimony of Plutarch, taught him some secret doctrines which he communicated to none other. The study of philosophy did not render the manners of Aristotle austere. He applied to business, and took an interest in everything that passed at the court of Macedonia. From respect to this philosopher, Philip rebuilt Stagira, his native city, which had been destroyed during the wars, and restored to their pos- sessions all the inhabitants, of whom some had fled and others had been reduced to slavery. When Alexander's education was finished, Aristotle returned to Athens, where he was well received on account of the mildness with which, for his sake, that city had been treated by Philip. He fixed upon a place in the Lyceum highly beautified with avenues of trees, where he established his school. He used to walk about when teaching and from this circumstance his sect was called
