These metaphors suggest that the doctrine of transmigration or reincarnation does not promise what we call personal immortality. I confess that I cannot understand how there can be personality in the ordinary human sense without a body. When we think of a friend, we think of a body and a character, thoughts and feelings, all of them connected with that body and many of them conditioned by it. But the immortal soul is commonly esteemed to be something equally present in a new born babe, a youth and an old man. If so, it cannot be a personality in the ordinary sense, for no one could recognize the spirit of a departed friend, if it is something which was present in him the day he was born and different from all the characteristics which he acquired during life. The belief that we shall recognize our friends in another world assumes that these characteristics are immortal, but it is hard to understand how they can be so, especially as it is also assumed that there is nothing immortal in a dog, which possesses affection and intelligence, but that there is something immortal in a new born infant which cannot be said to possess either. In one way metempsychosis raises insuperable difficulties to the survival of personality, for if you become someone else, especially an animal, you are no longer yourself according to any ordinary use of language. But one of the principal forms taken by the doctrine in India makes a modified survival intelligible. For it is held that a new born child brings with it as a result of actions done in previous lives certain predispositions and these after being developed and modified in the course of that child's life are transmitted to its next existence. As to the method of transmission there are various theories, for in India the belief in reincarnation is not so much a dogma as an instinct innate in all and only occasionally justified by philosophers, not because it was disputed but because they felt bound to show that their own systems were compatible with it. One explanation is that given by the Vedânta philosophy, according to which the soul is accompanied in its migrations by the _Sûkshmaśarîra_ or subtle body, a counterpart of the mortal body but transparent and invisible, though material. The truth of this theory, as of all theories respecting ghosts and spirits, seems to me a matter for experimental verification, but the Vedânta recognizes that in our experience a personal individual existence is always connected with a physical substratum.
