Upon this very principle it is much more likely that the philosophic cults of water, earth, air, and fire originated in the worships of Gods of those elements, whose priests would tend to magnify their office. It is hard to see how "temperament" could determine a man's bias to an air-theory in preference to a water-theory. But if the priests of Ea the Water-God and those of Bel the God of Air had framed theories of the kind, it is conceivable that family or tribal ties and traditions might set men upon developing the theory quasi-philosophically when the alien Gods came to be recognized by thinking men as mere names for the elements. [489] (Compare Flaubert's Salammbô as to the probable rivalry of priests of the Sun and Moon.) A pantheistic view, again, arose as we saw among various priesthoods in the monarchies where syncretism arose out of political aggregations. What is clear is that the religious or theistic basis had ceased to exist for many educated Greeks in that environment. The old God-ideas have disappeared, and a quasi-scientific attitude has been taken up. It is apparently conditioned, perhaps fatally, by prior modes of thought; but it operates in disregard of so-called religious needs, and negates the normal religious conception of earthly government or providence. Nevertheless, it was not destined to lead to the rationalization of popular thought; and only in a small number of cases did the scientific thinkers deeply concern themselves with the enlightenment of the mass. In another Ionian thinker of that age, indeed, we find alongside of physical and philosophical speculation on the universe the most direct and explicit assault upon popular religion that ancient history preserves. Xenophanes of Kolophon (? 570-470), a contemporary of Anaximandros, was forced by a Persian invasion or by some revolution to leave his native city at the age of twenty-five; and by his own account his doctrines, and inferribly his life, had gone "up and down Greece"--in which we are to include Magna Graecia--for sixty-seven years at the date of writing of one of his poems. [490] This was presumably composed at Elea (Hyela or Velia), founded about 536 B.C., on the western Italian coast, south of Paestum, by unsubduable Phokaians seeking a new home after the Persian conquest, and after they had been further defeated in the attempt to live as pirates in Corsica. [491] Thither came the aged Xenophanes, perhaps also seeking freedom. He seems to have lived hitherto as a rhapsode, chanting his poems at the courts of tyrants as the Homerids did the Iliad. It is hard indeed to conceive that his recitations included the anti-religious passages which have come down to us; but his resort in old age to the new community of Elea is itself a proof of a craving and a need for free conditions of life.
