The tragedians.

41. The development of philosophic thought at Athens was, as we have noticed, much complicated by the political relations of Greece to Persia. Although the Persian empire had absorbed Asia Minor, it was decisively repulsed in its attacks on Greece proper. Athens was the centre of the resistance to it, and the chief glory of the victories of Marathon (490 B.C.) and Salamis (480 B.C.) fell to Athenian statesmen and warriors. By these successes the Hellenes not only maintained their political independence, but saved the images of their gods from imminent destruction. A revival of polytheistic zeal took place, as might have been expected. The wealth and skill of Greece were ungrudgingly expended in the achievement of masterpieces of the sculptor’s art, and their housing in magnificent temples. But even so religious doctrines strikingly similar to those of the Persians gained ground. The same Aeschylus who (in his Persae) celebrates the defeat of the national enemy, a few years later (in his Agamemnon) questions whether the Supreme Ruler be really pleased with the Greek title of Zeus, and the Greek method of worshipping him[46]. His more conservative successor Sophocles was contented, in the spirit of the Homeric bards, to eliminate from the old myths all that seemed unworthy of the divine nature. Euripides adopts a bolder tone. Reproducing the old mythology with exact fidelity, he ‘assails the resulting picture of the gods with scathing censure and flat contradiction[47].’ With equal vigour he attacks the privileges of noble birth, and defends the rights of the slave; he has a keen sympathy for all the misfortunes that dog man’s life; but his ethical teaching in no way derives its sanction from any theology. The Hellenes have lost confidence in their inherited outlook on the world.

The Sophists.

42. The same problems which the poets discussed in the city theatre were during the fifth century B.C. the themes of a class of men now becoming so numerous as to form the nucleus of a new profession. These were the ‘sophists,’ who combined the functions now performed partly by the university professor, partly by the public journalist[48]. Dependent for their livelihood upon the fees of such pupils as they could attract, and therefore sensitive enough to the applause of the moment, they were distinguished from the philosophers by a closer touch with the public opinion of the day, and a keener desire for immediate results. Their contribution to philosophic progress was considerable. Cultivating with particular care the art of words, they created a medium by which philosophic thought could reach the crowd of men of average education; eager advocates of virtue and political progress, they gave new hopes to a people which, in spite of its material successes, was beginning to despair because of the decay of its old moral and civic principles. In Prodicus of Ceos we find a forerunner of the popular Stoic teachers of the period of the principate[49]:

‘A profound emotion shook the ranks of his audience when they heard his deep voice, that came with so strange a sound from the frail body that contained it. Now he would describe the hardships of human existence; now he would recount all the ages of man, beginning with the new-born child, who greets his new home with wailing, and tracing his course to the second childhood and the gray hairs of old age. Again he would rail at death as a stony-hearted creditor, wringing his pledges one by one from his tardy debtor, first his hearing, then his sight, next the free movement of his limbs. At another time, anticipating Epicurus, he sought to arm his disciples against the horrors of death by explaining that death concerned neither the living nor the dead. As long as we live, death does not exist; as soon as we die, we ourselves exist no longer[50].’

To Prodicus we owe the well-known tale of Hercules at the parting of the ways, when Virtue on the one hand, and Pleasure on the other, each invite him to join company with her[51]. This tale we shall find to be a favourite with the Roman philosophers. The same Prodicus introduced a doctrine afterwards taken up by the Cynics and the Stoics in succession, that of the ‘indifference’ of external advantages as distinct from the use to which they are applied. He also propounded theories as to the origin of the gods of mythology, explaining some of them as personifications of the powers of nature, others as deified benefactors of the human race[52]; theories which later on were adopted with zeal by the Stoic Persaeus[53]. To another sophist, Hippias of Elis, we owe the doctrine of the ‘self-sufficiency’ of virtue, again adopted both by Cynics and Stoics[54]. Antiphon was not only the writer of an ‘Art of Consolation,’ but also of a treatise of extraordinary eloquence on political concord and the importance of education. ‘If a noble disposition be planted in a young mind, it will engender a flower that will endure to the end, and that no rain will destroy, nor will it be withered by drought[55].’

The Materialists.

43. Amongst the sophists of Athens was counted Anaxagoras, born at Clazomenae about 500 B.C., and a diligent student of the Ionic philosophers. But in his explanation of nature he broke away from ‘hylozoism’ and introduced a dualism of mind and matter. ‘From eternity all things were together, but Mind stirred and ordered them[56].’ More famous was his contemporary Empedocles of Agrigentum, whose name is still held in honour by the citizens of that town. In him we first find the list of elements reaching to four, earth, air, fire, and water; and the doctrine that visible objects consist of combinations of the elements in varying proportions, first brought together by Love, then separated by Hatred. Just in so far as Empedocles abandoned the quest after a single origin for all things, his conceptions became fruitful as the basis of the more limited study now known as Chemistry. His work was carried further by Leucippus and Democritus, both of Abdera, who for the four elements substituted invisible atoms, of countless variety, moving by reason of their own weight in an empty space. This simple and powerful analysis is capable of dealing effectively with many natural phenomena, and with comparatively slight alterations is still held to be valid in chemical analysis, and exercises a wide influence over the neighbouring sciences of physics and botany. When however (as has frequently been the case both in ancient and modern times) the attempt is made to build upon it a general philosophical system, its failure to explain the cohesion of matter in masses, the growth of plants and animals, and the phenomena of mind, become painfully apparent. Such attempts roughly correspond to the attitude of mind now called materialism, because in them the atoms, endowed with the material properties of solidity, shape, and weight alone, are conceived to be the only true existences, all others being secondary and derivative. This materialism (with some significant qualifications) was a century later the central doctrine of Epicurus, and is of importance to us by reason of its sharp contrast with the Stoic system of physics.

Socrates.

44. The value of these scientific speculations was not for the time being fully recognised at Athens. It was in the atmosphere of sophistic discussion, not free from intellectual mists, but bracing to the exercise of civic and even of martial virtue that Socrates of Athens (circ. 469-399 B.C.) grew to maturity. He set to his fellow-citizens an example of the vigorous performance of duty. As a soldier he was brave almost to rashness, and took an active part in three campaigns. As a magistrate he discharged his duty unflinchingly. After the battle of Arginusae the ten Athenian generals were said to have neglected the duty of succouring certain disabled ships and the people loudly demanded that all should be condemned to death by a single vote. Socrates was one of the presiding senators, and he absolutely refused to concur in any such illegal procedure[56a]. Again, when Athens was under the rule of the Thirty, Socrates firmly refused to obey their unjust orders[57]. But when himself condemned to death, he refused to seize an opportunity for flight which was given him; for this, he said, would be to disobey the laws of his country[58].
