The Greeks varied from the general type of culture-evolution seen in India, Persia, Egypt, and Babylon, and approximated somewhat to that of ancient China, in that their higher thinking was done not by an order of priests pledged to cults, but by independent laymen. In Greece, as in China, this line of development is to be understood as a result of early political conditions--in China, those of a multiplicity of independent feudal States; in Greece, those of a multiplicity of City States, set up first by the geographical structure of Hellas, and reproduced in the colonies of Asia Minor and Magna Graecia by reason of the acquired ideal and the normal state of commercial competition. To the last, many Greek cults exhibited their original character as the sacra of private families. Such conditions prevented the growth of a priestly caste or organization. [462] Neither China nor Pagan Greece was imperialized till there had arisen enough of rationalism to prevent the rise of a powerful priesthood; and the later growth of a priestly system in Greece in the Christian period is to be explained in terms first of a positive social degeneration, accompanying a complete transmutation of political life, and secondly of the imposition of a new cult, on the popular plane, specially organized on the model of the political system that adopted it. Under imperialism, however, the two civilizations ultimately presented a singular parallel of unprogressiveness. In the great progressive period, the possible gains from the absence of a priesthood are seen in course of realization. For the Greek-speaking world in general there was no dogmatic body of teaching, no written code of theology and moral law, no Sacred Book. [463] Each local cult had its own ancient ritual, often ministered by priestesses, with myths, often of late invention, to explain it; [464] only Homer and Hesiod, with perhaps some of the now lost epics, serving as a general treasury of myth-lore. The two great epopees ascribed to Homer, indeed, had a certain Biblical status; and the Homerids or other bards who recited them did what in them lay to make the old poetry the standard of theological opinion; but they too lacked organized influence, and could not hinder higher thinking. [465] The special priesthood of Delphi, wielding the oracle, could maintain their political influence only by holding their function above all apparent self-seeking or effort at domination. [466] It only needed, then, such civic conditions as should evolve a leisured class, with a bent towards study, to make possible a growth of lay philosophy.
