But for his audacity, the philosopher suffered the fate of Galileo in a later age; he was charged with impiety and exiled. Yet this did not disturb the serenity of his mind. In banishment he said, "It is not I who have lost the Athenians, but the Athenians who have lost me."
EMPEDOCLES AND DEMOCRITUS.—In the teachings of Empedocles (about 492-432 B.C.) and Democritus (about 460-370 B.C.) we meet with many speculations respecting the constitution of matter and the origin of things which are startlingly similar to some of the doctrines held by modern scientists. Empedocles, with the evolutionists of to-day, taught that the higher forms of life arise out of the lower; Democritus conceived all things to be composed of invisible atoms, all alike in quality, but differing in form and combination.
THE SOPHISTS.—The Sophists, of whom the most noted were Protagoras, Gorgias, and Prodicus, were a class of philosophers or teachers who gave instruction in rhetoric and the art of disputation. They travelled about from city to city, and contrary to the usual custom of the Greek philosophers, took fees from their pupils. They were shallow but brilliant men, caring more for the dress in which the thought was arrayed than for the thought itself, more for victory than for truth; and some of them inculcated a selfish morality. The better philosophers of the time despised them, and applied to them many harsh epithets, taunting them with selling wisdom, and accusing them of boasting that they could "make the worse appear the better reason."
SOCRATES.—Volumes would not contain what would be both instructive and interesting respecting the lives and works of the three great philosophers Socrates, Plato, and Aristotle. We can, however, accord to each only a few words. Of these three eminent thinkers, Socrates (469-399 B.C.), though surpassed in grasp and power of intellect by both Plato and Aristotle, has the firmest hold upon the affections of the world.
Nature, while generous to the philosopher in the gifts of soul, was unkind to him in the matter of his person. His face was ugly as a satyr's, and he had an awkward, shambling walk, so that he invited the shafts of the comic poets of his time. He loved to gather a little circle about him in the Agora or in the streets, and then to draw out his listeners by a series of ingenious questions. His method was so peculiar to himself that it has received the designation of the "Socratic dialogue." He has very happily been called an educator, as opposed to an instructor. In the young men of his time Socrates found many devoted pupils. The youthful Alcibiades declared that "he was forced to stop his ears and flee away, that he might not sit down by the side of Socrates and grow old in listening."

Socrates was unfortunate in his domestic relations. Xanthippe, his wife, seems to have been of a practical turn of mind, and unable to sympathize with the abstracted ways of her husband.
This great philosopher believed that the proper study of mankind is man, his favorite maxim being "Know Thyself"; hence he is said to have brought philosophy from the heavens and introduced it to the homes of men.
Socrates held the Sophists in aversion, and in opposition to their selfish expediency taught the purest system of morals that the world had yet known, and which has been surpassed only by the precepts of the Great Teacher. He thought himself to be restrained from entering upon what was inexpedient or wrong by a tutelary spirit. He believed in the immortality of the soul and in a Supreme Ruler of the universe, but sometimes spoke slightingly of the temples and the popular deities. This led to his prosecution on the double charge of blasphemy and of corrupting the Athenian youth. The fact that Alcibiades had been his pupil was used to prove the demoralizing tendency of his teachings. He was condemned to drink the fatal hemlock. The night before his death he spent with his disciples, discoursing on the immortality of the soul.
PLATO.—Plato (429-348 B.C.), "the broad-browed," was a philosopher of noble birth, before whom in youth a brilliant career in the world of Greek affairs opened; but, coming under the influence of Socrates, he resolved to give up all his prospects in politics and devote himself to philosophy. Upon the condemnation and death of his master he went into voluntary exile. In many lands he gathered knowledge and met with varied experiences. He visited Sicily, where he was so unfortunate as to call upon himself the resentment of Dionysius, tyrant of Syracuse, through having worsted him in an argument, and also by an uncourtly plainness of speech. The king caused him to be sold into slavery as a prisoner of war. Being ransomed by a friend, he found his way to his native Athens, and established a school of philosophy in the Academy, a public garden close to Athens. Here amid the disciples that thronged to his lectures, he passed the greater part of his long life,—he died 348 B.C., at the age of eighty-one years,—laboring incessantly upon the great works that bear his name.
