all this paleo-anthropology has, up to date, almost nothing to tell us. Nor do we see much reason to believe it ever will. All these culture stages of the Old Stone Age have left us little but material vestiges of its industries--bones, a few carvings on cave walls or on bones and ivory, and very many chipped flints. Nothing of wood, skin, fiber or other material for binding, which must have been used, survives.[32] Much as these bones and stones tell us, they have really done more to increase our curiosity than to satisfy it. We know almost nothing of how these thousands of generations of men viewed life or nature, or in what spirit and with what knowledge they met disease, age, and death. What is called belief in another life is for primitives or children only inability to grasp completely the very difficult fact of death and to distinguish it from sleep. The disposition of some of the troglodyte skeletons suggests that these ancient forbears of our race were unable to realize that death ends all. Despite the close analogy and even kinship between human and animal life so deeply felt in early days, it was probably always somewhat harder for early man to conceive death for himself as complete cessation than to so conceive it for the higher forms of animal life with which his own was so intimately associated. Our ignorance of all these stages of human evolution becomes all the more pathetic as we are now coming to understand that it was then that all the deeper unconscious and dispositional strata of Mansoul, which still dominate us far more than we are even yet aware, were being laid down, and it is upon these traits that the later and conscious superstructure of our nature has been reared. Only hard things survive the ravages of time, and psychic traits and trends are the softest of all soft things, although they are no less persistent by way of biological and social inheritance than skeletons and flints.
