discountenanced the impiety so obvious in the 'Prometheus Bound' of Æschylus. It was by appealing to this sentiment that Aristophanes added no little to the excitement against Socrates. They who are doubting themselves are often loudest in public denunciations of a similar state in others. [Sidenote: Secession of the philosophers.] If thus the poets, submitting to common sense, had so rapidly fallen away from the national belief, the philosophers pursued the same course. It soon became the universal impression that there was an intrinsic opposition between philosophy and religion, and herein public opinion was not mistaken; the fact that polytheism furnished a religious explanation for every natural event made it essentially antagonistic to science. It was the uncontrollable advance of knowledge that overthrew Greek religion. Socrates himself never hesitated to denounce physics for that tendency; and the Athenians extended his principles to his own pursuits, their strong common sense telling them that the philosophical cultivation of ethics must be equally bad. He was not loyal to science, but sought to support his own views by exciting a theological odium against his competitors--a crime that educated men ought never to forgive. In the tragedy that ensued the Athenians only paid him in his own coin. The immoralities imputed to the gods were doubtless strongly calculated to draw the attention of reflecting men, but the essential nature of the pursuit in which the Ionian and Italian schools were engaged bore directly on the doctrine of a providential government of the world. It not only turned into a fiction the time-honoured dogma of the omnipresence of the Olympian divinities--it even struck at their very existence, by leaving them nothing to do. For those personifications it introduced impersonal nature or the elements. Instead of uniting scientific interpretations to ancient traditions, it modified and moulded the old traditions to suit the apparent requirements of science. We shall subsequently see what was the necessary issue of this--the Divinity became excluded from the world he had made, the supernatural merged in natural agency; Zeus was superseded by the air, Poseidon by the water; and while some of the philosophers received in silence the popular legends, as was the case with Socrates, or, like Plato, regarded it as a patriotic duty to accept the public faith, others, like Xenophanes, denounced the whole as an ancient blunder, converted by time into a national imposture. [Sidenote: Antagonism of science and polytheism.] As I shall have occasion to speak of Greek philosophy in a detailed manner, it is unnecessary to enter into other particulars here. For the present purpose it is enough to understand that it was radically opposed to the national faith in all countries and at all times, from its origin with Thales down to the latest critic of the Alexandrian school.
