Plutarch connects with his belief in the gods "the great hypothesis" of immortality. "It is one argument that at one and the same time establishes the providence of God and the continuance of the human soul, and you cannot do away with the one and leave the other."[110] If we had nothing divine in us, nothing like God, if we faded like the leaves (as Homer said), God would hardly give us so much thought, nor would he, like women with their gardens of Adonis, tend and culture "souls of a day," growing in the flesh which will admit no "strong root of life." The dialogue, in which this is said, is supposed to have taken place in Delphi, so Plutarch turns to Apollo. "Do you think that, if Apollo knew that the souls of the dying perished at once, blowing away like mist or smoke from their bodies, he would ordain so many propitiations for the dead, and ask such great gifts and honours for the departed--that he would cheat and humbug believers? For my part, I will never let go the continuance of the soul, unless some Herakles shall come and take away the Pythia's tripod and abolish and destroy the oracle. For as long as so many oracles of this kind are given even in our day, it is not holy to condemn the soul to {105} death."[111] And Plutarch fortifies his conviction with stories of oracles, and of men who had converse with daemons, with apocalypses and revelations, among which are two notable Descents into Hades,[112] and a curious account of daemons in the British Isles.[113] The theory of daemons lent itself to the explanation of the origin of evil, but speculation in this direction seems not to have appealed to Plutarch. He uses bad daemons to explain the less pleasant phases of paganism, as we shall see, but the question of evil he scarcely touches. In his book on Isis and Osiris he discusses Typhon as the evil element in nature, and refers with interest to the views of "the Magian Zoroaster who, they say, lived about five hundred years before the Trojan War." Zoroaster held that there were two divine beings, the better being a god, Horomazes (Ormuzd), the other a daemon Areimanios (Ahriman), the one most like to light of all sensible things, the other to darkness and ignorance, "and between them is Mithras, for which reason the Persians call Mithras the Mediator." But the hour of Mithras was not yet come, and in all his writings Plutarch hardly alludes to him more than half a dozen times.[114] It should be noted that, whatever his interest in Eastern dualism with its Western parallels, Plutarch does not abandon his belief in the One Ultimate Good God.
