In the attitude of these old people to this problem the psychologist can glimpse a little of the _tedium vitæ_ that perhaps first produced and then discarded the Oriental doctrine of eternal recurrence of life and death, a psychic trend that gave birth to and vitalized metempsychosis and that impelled the Buddha to break away and find a goal beyond it. It needs little psychology to see that such attitudes of mind imply a deep dissatisfaction with any form of future existence that would be in essence a repetition of life here, even with moderate improvements on our present state of existence. A postmortem form of survival or revival that is, in any large sense, a reduplication of this could never bring a deep satisfaction. All ancient creeds and all modern philosophies of recurrence, for example, that of Nietzsche, have always been strongholds of pessimism and are really anti-evolutionary, although they are sometimes said to presage modern theories of development. To the genetic philosopher it would seem, from such data, that senescents tend to lose the sense that infancy and childhood are more generic than adulthood, that the latter brings the “shades of the prisonhouse,” and that every stage of individual development brings added limitations, so that our matured consciousness is only a very partial expression of the vaster life of the race, most of which is more and more repressed and incapable of coming to consciousness as life proceeds. If each of us might have lived very different lives from what we have done, and if many and varied lives are required to express all the possibilities with which we all start, it would seem as if each individual would have chosen, when he had played one part, to assume another in the _comédie humaine_ and then another, and so on; that the slave would want to complement his defects of opportunity by becoming king--if not, indeed, _vice versa_. When the psychic life of the race was young and rank, great minds did dream even of living out every phase and stage of life: of being animals, of experiencing every lot and station of humanity. But now that the world is older and the hyperindividuation that comes with age has supervened, this passion to taste everything possible to our estate is lost. Instead of sampling every dish we make a full meal of one and other viands are refused for we are sated. Biology teaches, as we have seen, that specialization is death and a hypertrophied personal consciousness is psychic specialization.
