In the first place, he can watch himself, that he does not mentally begin to grow old. To begin mentally to grow old is to begin mentally to die. He must think of himself as an expanding being, not as a contracting one. He must keep in sympathetic touch with the new, damning the know-it-all frame of mind. He must keep in sympathetic touch with youth, knowing that youth is the next generation in advance. The secrets of one generation are not those of another; but if he who possesses the earlier masters also the later he is that much the richer and wiser. The gulf which separates parents and children is one which the parents must cross. They can work onward, while the children cannot work backward. Up to a certain point the older teach the younger; beyond a certain point the younger teach the older. He who would go on living and not begin to die must be willing to be taught, reaping the harvest of both youth and age. In the second place, he who would live must not kill anyone else. The deadly tendency in ourselves is forever at work on those about us, chiefly on those we love. We watch, tabulate, and recount their symptoms of decay. Making notes of them for ourselves we discourse of them to others. "He begins to look old," is a commonplace. The response will probably emphasise the fact. By response to response we spin round a friend the age-web which lengthens into the death-web. In our expressive American vernacular we speak of "wishing" conditions on others, an instinctive folk-recognition of the force of mentality. We do it in a sinister sense more often than by way of helpfulness. We "wish" by thinking, by talking, by creating an atmosphere, by forcing things into the general consciousness. Old age and decay, bad enough in themselves, we intensify by our habits of mind. Death, which in any case awaits our friends, we woo to them by anticipations of demise. It is not ill-intentioned. It comes out of a subconsciousness in which death and not life is the base. IV For most of us the fear of death is a subconscious rather than an active fear. It becomes active for those who through illness, or in some other way, see a sentence of death hanging over them; but during the greater part of the life-span we are able to beat it off. As to the life-span itself there is reason to suppose that it is meant to be more regular than man allows it to become. There may easily be an "appointed time" to which we do not suffer ourselves, or each other, to attain. Those strange, inequalities by which one human being is left to pass over the century mark, another is cut off just when he is most needed, while a third does no more than touch this plane for an hour or two, may be the results of our misreadings of God's Will, and not the decrees of that Will itself.
