Nor is the other hypothesis any better, according to which the other life was imagined as a means of escaping the agonizing prospect of annihilation. In the first place, it is not true that the need of personal survival was actively felt at the beginning. The primitive generally accepts the idea of death with a sort of indifference. Being trained to count his own individuality for little, and being accustomed to exposing his life constantly, he gives it up easily enough.[864] More than that, the immortality promised by the religions he practices is not personal. In a large number of cases, the soul does not continue the personality of the dead man, or does not continue it long, for, forgetful of its previous existence, it goes away, after a while, to animate another body and thus becomes the vivifying principle of a new personality. Even among the most advanced peoples, it was only a pale and sad existence that shades led in Sheol or Erebus, and could hardly attenuate the regrets occasioned by the memories of the life lost.
A more satisfactory explanation is the one attaching the conception of a posthumous life to the experiences of dreams. Our dead friends and relatives reappear to us in dreams: we see them act, we hear them speak; it is natural to conclude that they continue to exist. But if these observations were able to confirm the idea after it had once been born, they hardly seem capable of creating it out of nothing. Dreams in which we see departed persons living again are too rare and too short and leave only too vague recollections of themselves, to have been able to suggest so important a system of beliefs to men all by themselves. There is a remarkable lack of proportion between the effect and the cause to which it is attributed.
What makes this question embarrassing is the fact that in itself, the idea of the soul does not imply that of its survival, but rather seems to exclude it. In fact, we have seen that the soul, though being distinguished from the body, is believed, nevertheless, to be closely united to it: it ages along with the body, it feels a reaction from all the maladies that fall upon the body; so it would seem natural that it should die with the body. At least, men ought to have believed that it ceased to exist from the moment when it definitely lost its original form, and when it was no longer what it had been. Yet it is at just this moment that a new life opens out before it.
