And again, if God be true, he cannot be the author of lies. How then could he have sent, as we are told he did, lying dreams to men?-- Clearly, concludes the philosopher, our current legends need revision; in the interest of religion itself we must destroy the myths of the popular creed. Section 14. Transition to Monotheism. The myths, but not religion! The criticism certainly of Plato and probably of Euripides was prompted by the desire not to discredit altogether the belief in the gods, but to bring it into harmony with the requirements of a more fully developed consciousness. The philosopher and the poet came not to destroy, but to fulfil; not to annihilate but to transform the popular theology. Such an intention, strange as it may appear to us with our rigid creeds, we shall see to be natural enough to the Greek mind, when we remember that the material of their religion was not a set of propositions, but a more or less indeterminate body of traditions capable of being presented in the most various forms as the genius and taste of individual poets might direct. And we find, in fact, that the most religious poets of Greece, those even who were most innocent of any intention to innovate on popular beliefs, did nevertheless unconsciously tend to transform, in accordance with their own conceptions, the whole structure of the Homeric theology. Taking over the legends of gods and heroes, as narrated in poetry and tradition, the earlier tragedians, Aeschylus and Sophocles, as they shaped and reshaped their material for the stage, were evolving for themselves, not in opposition to but as it were on the top of the polytheistic view, the idea of a single supreme and righteous God. The Zeus of Homer, whose superiority, as we saw, was based on physical force, grows, under the hands of Aeschylus, into something akin to the Jewish Jehovah. The inner experience of the poet drives him inevitably to this transformation. Born into the great age of Greece, coming to maturity at the crisis of her fate, he had witnessed with his own eyes, and assisted with his own hands the defeat of the Persian host at Marathon. The event struck home to him like a judgment from heaven. The Nemesis that attends upon human pride, the vengeance that follows crime, henceforth were the thoughts that haunted and possessed his brain; and under their influence he evolved for himself out of the popular idea of Zeus the conception of a God of justice who marks and avenges crime. Read for example the following passage from the "Agamemnon" and contrast it with the lines of Homer quoted on page 42. Nothing could illustrate more strikingly the transformation that could be effected, under the conditions of the Greek religion, in the whole conception of the divine power by one whose conscious intention, nevertheless, was not to innovate but to conserve.
