The theologians and philosophers of India might devise various methods for the believer's escape from the round of re-births; but on the ecclesiastical side they never surmounted the practical limitation of nationality, or sought to address themselves to the world at large; while the mystics who more easily passed the bounds of race usually lacked the aggressive energy which demanded the conquest and suppression of evil and the assurance of the victory of good. It was reserved for the Persian thinkers, led by Zarathustra, to work out a scheme for the ultimate overthrow of the power of "the Lie" (p. 211). Egyptian theology had impersonated the forces of evil in Set. There were the constant oppositions of darkness {247} and light, of sickness and health, of the desert against fertility, of drought against the Nile, of foreign lands against Egypt. Mythically, the antagonism between Set and his brother Osiris was continued by Isis' son Horus. It was renewed again and again, and Set was for ever defeated, yet always returned afresh to the strife. But no demand was raised for his elimination. Osiris had passed into the land of Amenti, where Set could trouble him no more. And apparently the later identification of the deceased with Osiris meant that for him, too, the powers of death and evil were overcome. But this did not affect Set's activity in the existing scene, where the strife continued over the survivors day by day. The insight of the Iranian prophet could not admit this division of spheres, and demanded not only new heavens, but also a new earth, where evil should have no more power, and the Righteous Order, the Good Mind, the Bounteous Spirit, and the rest of the Immortals, should be the unchallenged ministers of Ahura's rule.
