Yet at the risk of repetition, I would recall the fact that the practice of religion by individuals had not ceased at Athens. The common man still paid devotion to his guardian gods, made offerings to the dead, and shared in many forms of worship. Furthermore the spread of the Eleusinian mysteries in this century, so that a new and larger initiation hall had to be erected at Eleusis, shows that thoughts of the future life and the deepest religious feelings still existed in large numbers of the citizens. We have here, then, an apparent contradiction, such as has appeared many times and in many places in the religious history of man. Many of the leaders of the state were interested in religion only as it was an affair of state, in the same way in which the army and navy were. On the other hand there were large numbers who felt a more personal interest in religion and who cultivated a more personal relation to divinity. Nor were there lacking men of the most intellectual class to deal with the higher concepts of religion which had been developing during the recent centuries. These ideas find their truest utterance in the work of the poets, and we have already seen how Pindar, Aeschylus, and Sophocles interpreted nobler views with regard to the gods, human conduct, and man’s relation to the divinities, to all Greece and especially to Athens which had now become the intellectual center of the Hellenic world. But another new force had been developing among the Greeks during the sixth century which was destined to deal a far greater blow to traditional religion than any other—I mean philosophy. This began in Ionia and was cultivated in other parts of greater Greece before it came to Athens. But after the Persian Wars the prominence and prosperity of that city was so great and her intellectual eminence was so high that she attracted the men of note in many departments of life. Among them was the philosopher Anaxagoras of Clazomenae who made Athens his home for about thirty years (c. 462-432 B.C.). He became a member of the most intellectual Athenian society of his day, a friend of Euripides, and an intimate of Pericles. When dangers began to threaten the state, with the prospect of war looming on the horizon, the people began to blame their great leader; to injure him, they banished one and another of his friends. The two most noted were Phidias the sculptor, of whose art the marbles of the Parthenon are still the unsurpassed witnesses, and Anaxagoras the philosopher; the charge against both was impiety. Anaxagoras taught that the sun was a red hot mass of rock, as the moon was a cold mass, like the earth. According to this teaching the sun and moon could no longer be regarded as gods, so that a charge of impiety was as easily based on such doctrines as it was on the teaching of Galileo twenty centuries later. But although the philosopher was driven out, philosophy could not be so easily banished. The eager intellectual life of Athens had
