All religions have given a prominent place to the problem of existence and the origin of evil; all have attempted its solution. {56} The good and the evil genius, Ormuzd and Ahriman among the Persians; God the Creator, God the Preserver, and God the Destroyer--Brahma, Vishnu, and Siva--in India; the Titans overwhelmed by the thunderbolts of Jove while scaling Olympus; Prometheus chained to the rock for having snatched fire from heaven; all are so many hypotheses to explain the conflict between good and evil, between order and disorder in the world and in man. But all these hypotheses are complicated, confused, and encumbered with chimeras and fables; all attribute the derivation of evil to incongruous causes, none assign any term to the conflict, nor find a remedy for the evil. The Christian religion alone clearly states and effectually solves the question; it alone imputes to man himself, and to him alone, the origin of evil; it alone represents God as intervening to raise man from his fall, and to save him from his peril. {57} In the course of the sixth and fifth centuries before the Christian era, a great fact appears in history; a breath of reform, religious, moral and social, arises, and spreads from east to west, among all the nations then at all progressing in the path of civilization. Notwithstanding the uncertainties of chronology, it may be said, according to the most recent and accurate researches, that Confucius in China, the Buddha Càkya-Mouni in India, Zoroaster in Persia, Pythagoras and Socrates in Greece, are all included in the limits of this epoch; [Footnote 5] men as dissimilar as they are celebrated, but who have all, in different ways and in unequal degrees, undertaken a great work of reforming both the men and the social institutions of their times. [Footnote 5: These researches give the following dates:--1. Confucius, from 551 to 478 B.C.; 2. Zoroaster, from 564 to 487, or from 589 to 512 B.C.; 3. Buddha Càkya-Mouni, in the seventh and sixth centuries B.C. (he died, according to Burnouf, 543 B.C.); 4. Pythagoras, from 580 to 500 B.C.; 5. Socrates, 470 to 400 or 399 B.C.] {58}
