his fellow-disciples in natural endowments, of which he was possessed in a wonderful degree. Yet, deeming himself and the Socratic discipline far from sufficient for bringing philosophy to perfection, he travelled as extensively as he was able, going to every place famed for the cultivation of any science of which he could make himself master. Thus he learned from the Egyptians whatever they held and taught as important; and from Egypt, passing into those parts of Italy which were filled with the fame of the Pythagoreans, he mastered, with the greatest facility, and under the most eminent teachers, all the Italic philosophy which was then in vogue. And, as he had a peculiar love for his master Socrates, he made him the speaker in all his dialogues, putting into his mouth whatever he had learned, either from others, or from the efforts of his own powerful intellect, tempering even his moral disputations with the grace and politeness of the Socratic style. And, as the study of wisdom consists in action and contemplation, so that one part of it may be called active, and the other contemplative,—the active part having reference to the conduct of life, that is, to the regulation of morals, and the contemplative part to the investigation into the causes of nature and into pure truth,—Socrates is said to have excelled in the active part of that study, while Pythagoras gave more attention to its contemplative part, on which he brought to bear all the force of his great intellect. To Plato is given the praise of having perfected philosophy by combining both parts into one. He then divides it into three parts,—the first moral, which is chiefly occupied with action; the second natural, of which the object is contemplation; and the third rational, which discriminates between the true and the false. And though this last is necessary both to action and contemplation, it is contemplation, nevertheless, which lays peculiar claim to the office of investigating the nature of truth. Thus this tripartite division is not contrary to that which made the study of wisdom to consist in action and contemplation. Now, as to what Plato thought with respect to each of these parts,—that is, what he believed to be the end of all actions, the cause of all natures, and the light of all
