The doctrines of pre-existence and transmigration (but not, I think, of karma which is purely Indian) are common among savages in Africa and America, nor is their wide distribution strange. Savages commonly think that the soul wanders during sleep and that a dead man's soul goes somewhere: what more natural than to suppose that the soul of a new born infant comes from somewhere? But among civilized peoples such ideas are in most cases due to Indian influence. In India they seem indigenous to the soil and not imported by the Aryan invaders, for they are not clearly enunciated in the Rig Veda, nor formulated before the time of the Upanishads[37]. They were introduced by Buddhism to the Far East and their presence in Manichaeism, Neoplatonism, Sufiism and ultimately in the Jewish Kabbala seems a rivulet from the same source. Recent research discredits the theory that metempsychosis was an important feature in the earlier religion of Egypt or among the Druids[38]. But it played a prominent part in the philosophy of Pythagoras and in the Orphic mysteries, which had some connection with Thrace and possibly also with Crete. A few great European intellects[39]--notably Plato and Virgil—have given it undying expression, but Europeans as a whole have rejected it with that curiously crude contempt which they have shown until recently for Oriental art and literature. Considering how fixed is the belief in immortality among Europeans, or at least the desire for it, the rarity of a belief in pre-existence or transmigration is remarkable. But most people's expectation of a future life is based on craving rather than on reasoned anticipation. I cannot myself understand how anything that comes into being can be immortal. Such immortality is unsupported by a single analogy nor can any instance be quoted of a thing which is known to have had an origin and yet is even apparently indestructible[40]. And is it possible to suppose that the universe is capable of indefinite increase by the continual addition of new and eternal souls? But these difficulties do not exist for theories which regard the soul as something existing before as well as after the body, truly immortal _a parte ante_ as well as _a parte post_ and manifesting itself in temporary homes of human or lower shape. Such theories become very various and fall into many obscurities when they try to define the nature of the soul and its relation to the body, but they avoid what seems to me the contradiction of the created but immortal soul.
