With Socrates begins the second period of the Grecian philosophy. This period contains three philosophical systems, whose authors, standing to each other in the personal relation of teacher and pupil, represent three successive generations,—SOCRATES, PLATO, ARISTOTLE. SECTION XII. SOCRATES.[2] 1. HIS PERSONAL CHARACTER.—The new philosophical principle appears in the personal character of Socrates. His philosophy is his mode of acting as an individual; his life and doctrine cannot be separated. His biography, therefore, forms the only complete representation of his philosophy, and what the narrative of Xenophon presents us as the definite doctrine of Socrates, is consequently nothing but an abstract of his inward character, as it found expression from time to time in his conversation. Plato yet more regarded his master as such an archetypal personality, and a luminous exhibition of the historical Socrates is the special object of his later and maturer dialogues, and of these again, the Symposium is the most brilliant apotheosis of the Eros incarnated in the person of Socrates, of the philosophical impulse transformed into character. Socrates was born in the year 469 B. C, the son of Sophroniscus, a sculptor, and Phænarete, a midwife. In his youth he was trained by his father to follow his own profession, and in this he is said not to have been without skill. Three draped figures of the Graces, called the work of Socrates, were seen by Pausanias, upon the Akropolis. Little farther is known of his education. He may have profited by the instruction of Prodicus and the musician, Damon, but he stood in no personal connection with the proper philosophers, who flourished before, or cotemporaneously with him. He became what he was by himself alone, and just for this reason does he form an era in the old philosophy. If the ancients call him a scholar of Anaxagoras, or of the natural philosopher, Archelaus, the first is demonstrably false, and the second, to say the least, is altogether improbable. He never sought other means of culture than those afforded in his native city. With the exception of one journey to a public festival, the military campaigns which led him as far as Potidæa, Delion, and Amphipolis, he never left Athens.
