Socrates was of humble birth. He was born 469 B.C. and lived for seventy years. His father was a sculptor, and he followed the same profession. He married, and his wife Xanthippe has become famous for the acidity of her temper. There is little doubt that Socrates, whose life was spent in arguing and conversing, and who paid little attention to filling the larder, gave the poor housewife abundant provocation. We know very little about the events of his life, except that he served as a soldier in three campaigns, that he strictly obeyed the laws, performed all his religious duties, and once, when acting as judge, refused, at the peril of his life, to perform an unjust action. Of the daily life of Socrates we have graphic pictures, drawn by his friends and followers Xenophon and Plato. From morning to night he might be seen in the streets and public places, engaged in endless talk,--prattling, his enemies called it. In the early morning, his sturdy figure, shabbily dressed, and his pale and ill-featured face, were familiar visions in the public walks, the gymnasia, and the schools. At the hour when the market-place was most crowded, Socrates would be there, walking about among the booths and tables, and talking to every one whom he could induce to listen. Thus was his whole day spent. He was ready to talk with any one, old or young, rich or poor, being in no sense a respecter of persons. He conversed with artisans, philosophers, students, soldiers, politicians,--all classes of men. He visited everywhere, was known to all persons of distinction, and was a special friend of Aspasia, the brilliant woman companion of Pericles. His conversational powers must have been extraordinary, for none seemed to tire of hearing him, and many sought him in his haunts, eager to hear his engaging and instructive talk. Many, indeed, in his later years, came from other cities of Greece, drawn to Athens by his fame, and anxious to hear this wonderful conversationalist and teacher. These became known as his scholars or disciples, though he claimed nothing resembling a school, and received no reward for his teachings. The talk of Socrates was never idle or meaningless chat. He felt that he had a special mission to fulfil, that in a sense he was an envoy to man from the gods, and declared that, from childhood on, a divine voice had spoken to him, unheard by others, warning and restraining him from unwise acts or sayings. It forbade him to enter public life, controlled him day by day, and was frequently mentioned by him to his disciples. This guardian voice has become known as the daemon or genius of Socrates. The oracle at Delphi said that no man was wiser than Socrates. To learn if this was true and he really was wiser than other men, he questioned everybody everywhere, seeking to learn what they knew, and leading them on by question after question till he usually found that they knew very little of what they professed.
