THREE:Protagoras was born about 480 B.C. He was a fellow-townsman of Democritus, and has been represented, though not on good authority, as a disciple of that illustrious thinker. It was rather by a study of Heracleitus that his87 philosophical opinions, so far as they were borrowed from others, seem to have been most decisively determined. In any case, practice, not theory, was the principal occupation of his life. He gave instruction for payment in the higher branches of a liberal education, and adopted the name of Sophist, which before had simply meant a wise man, as an honourable title for his new calling. Protagoras was a very popular teacher. The news of his arrival in a strange city excited immense enthusiasm, and he was followed from place to place by a band of eager disciples. At Athens he was honoured by the friendship of such men as Pericles and Euripides. It was at the house of the great tragic poet that he read out a work beginning with the ominous declaration, I cannot tell whether the gods exist or not; life is too short for such difficult investigations.66 Athenian bigotry took alarm directly. The book containing this frank confession of agnosticism was publicly burned, all purchasers being compelled to give up the copies in their possession. The author himself was either banished or took flight, and perished by shipwreck on the way to Sicily before completing his seventieth year.They have not been able to maintain that story for very long; the truth overtook the lie.
