Thus the religion of childhood and manhood for the venerable sage is transmuted into philosophy or meditation on the most general problems and the very nature of not only life but being itself, that Plato described as the cult of death. The old man, thus, in the classic days of ancient India directed his thoughts toward absorption. His religion was pantheism, and the theme of his contemplation was the source of all things and their return to this source as their goal. Perhaps we might now say that according to this view, if evolution is the inspiration of the intellect in its youth and its prime, involution was its muse in the stages of decline as it awaited resumption into the One-and-All. Modern pragmatists, like the best of the ancient Sophists, hold that the truth that best fits and expresses Me is and must be held with the completest conviction, and the genetic idea is that different philosophies and different faiths fit and express not only different temperaments but different stages of life, and that, therefore, creeds can never be fixed and stationary but must be constantly transformed. There is no absolute or final form of truth for all save in the dominion of pure mathematical and physical science, and it is one of the most tragic aspects of our modern culture that we so often find mature and even aging men and women arrested in infantile or juvenile stages of their development in regard to the larger problems of life, for where and just in proportion as the latter is intense there is incessant change. Christianity is the best of all religions through the entire stage of the _vita sexualis_ from its inception to its decline. Its essence is the sublimation of love. It is the religion of personalization culminating in the faith in another individual life. It is not the religion for old men, and the revival of its attitudes, which we often see in them, is a phenomenon of arrest or reversion and not one of the advance that senescence should mark if the last stage of life is to have its complete unfoldment.
