I. Philosophical and Religious Ideas which created the Ethical Type

Religious dualism

In view of the mixed good and evil in the world, thinkers of antiquity, outside of Israel and before the rise of the Stoic philosophy in Greece, could not conceive the universe as being set in motion and directed by one God infinite at once in power and goodness. Even the most penetrating intellect of Greece faltered in his search for unity: “We cannot suppose,” says Plato, “that the universe is ordered by one soul; there must be more than one, probably not less than two—one the author of good, and the other of evil.”[302] The seers of Israel alone reached with perfect conviction the height of the great argument, and announced confidently that He who is the author of the good in the world is the author likewise of the evil: “I form the light and create the darkness; I make peace and create evil,” are the words which the prophet Isaiah puts in the mouth of Yahweh.[303]

The religious thinkers of Persia never reached this lofty viewpoint. It seemed to them, as it seemed to the Greek philosopher, that at least two deities must have been concerned in the creation and ordering of the universe. They believed in the existence of two great powers: a good being, Ahura Mazda, the creator of light and of all beneficent things; and an evil being, Ahriman, the author of darkness and of all baneful creatures. Between these two powers they conceived to be going on a fierce struggle for the mastery, in which ultimate victory was assured to the good Ahura.[304]

This Persian world philosophy reacted favorably upon the moral character, and, as we shall see further on, contributed to create in ancient Persia a deep consciousness of the eternal distinction between good and evil, a profound sentiment of duty, and an active, strenuous morality.[305] It is when contrasted with the world philosophy of Brahmanism and Buddhism that the ethical value of this dualistic philosophy of the old Persian thinkers is best disclosed.

Conception of the character of the supreme god, Ahura Mazda

While it is true that the moral qualities attributed by a people to their gods are nothing more nor less than the moral qualities possessed or revered by this people themselves, still it is also true that the moral nature thus given to the gods reacts powerfully upon the ethical life of their worshipers and tends to mold their moral character after the heavenly type. In a word, celestial morality is at once effect and cause.

In the case of no other people of antiquity, except the people of Israel, did the conception of deity exercise a greater influence upon morality than in that of the ancient Persians. The supreme being, Ahura Mazda, was conceived, as we have already noted, as the creator of the light and of all good things, as the god of righteous order and benevolence. He was the lover of truth. Truth was the innermost essence of his being, as love is the innermost essence of the God of Christianity. Farther on we shall see how this conception of deity formed the mold in which was cast the Persian ideal of moral excellence.

The ethical character of Mithra

Ahura Mazda was the god of the sky. As time passed, Mithra, the god of the sun, gradually came into greater prominence and finally quite eclipsed the at first supreme deity, Ahura. As the solar god he appropriated the ethical attributes of the sky god and became preëeminently the god of light, the champion of truth, and the avenger of lies. He it is who, when not deceived, establisheth nations in victory and strength.[306]

It was from this solar deity that Zoroastrianism in the later pre-Christian centuries was called Mithraism, under which name, as we shall see, it entered the Greco-Roman world and there became a chief competitor with Christianity for the control and guidance of the moral life of the European nations.

Doctrine of the sacredness of the elements​— ​fire, earth, and water

The principle of Persian world philosophy which, next after that of the divided government of the universe, had probably the greatest consequences, and those not wholly favorable, for Persian morality, was the principle of the purity and sacredness of the elements—fire, earth, and water. From this principle or belief were deduced endless ritual requirements whose aim was to preserve these elements from pollution, or to restore their purity after defilement, and thus one large division of the moral code embraced mainly artificial duties, duties which had no vital relation to natural morality, that is, to conduct deriving its sanction from the natural feelings of moral right and wrong.

The personality of a great reformer, Zarathustra

As the great moral systems of Confucianism, Buddhism, Christianity, and Mohammedanism bear each the impress of the moral consciousness of some great teacher, so is it with Zoroastrianism. For the moral ideal of Persia, while doubtless largely the creation of the ethical feelings and convictions of the Iranian race, developed through many centuries of race experiences, nevertheless bears the unmistakable imprint of a unique personality. That the Zarathustra of tradition represents a real historical personage, there can hardly be longer a reasonable doubt.[307]

The time of Zarathustra’s mission probably falls in the first half of the sixth century B.C. He thus belongs to that era in the history of antiquity when, at various centers of culture, reform movements announced the opening of a new epoch in the moral evolution of the human race.[308] The sum of what we may believe to have been his moral teachings was that man’s full duty is purity and sincerity in thought, word, and deed, and an untiring warfare against evil.
