Such is the truth of human possibility and our necessities as I perceive it, and that is the way man must live if our species is to survive and pass on to greater destinies. I set down the truth as it is given me to see it; for me there can be no other truth. On every hand about us all is the darkness of the unknown, but the light we have, when we have used our eyes to their utmost, must be our guide. Because of obtuseness and prepossessions, I may but run beside the realities I imagine I express. Necessarily reality which goes on all over the universe and for every instant of time, is infinitely more intricate and wonderful than any statement, teeming with possibilities still unsuspected. All the more do we need compass and map and plans to keep our direction through the jungle of its manifest marvels and dangers. That this presentation of the current phase of human life as the occasion for an Open Conspiracy to establish a world commonweal will seem to many an extreme simplification of our circumstances, should not condemn it. The value of a map lies in the fact that it is not a model nor a picture of reality but a reduced abstraction, sufficiently clear and sufficiently true to essentials and sufficiently free from irrelevancies to guide. This scheme to thrust forward and establish a human control over the destinies of life and liberate it from its present dangers, uncertainties and miseries, is offered here as an altogether practicable one, subject only to one qualification, that sufficient men and women will be willing to serve it. That there is no foretelling. It is clear that the whole growth is dependent upon the appearance of those primary groups, sustaining and spreading its fundamental ideas. Those ideas have to become the mental substratum of constructive effort. If those ideas can find sufficient vigorous, able and devoted people for their establishment, the rest will follow. There is need of much leadership, not indeed the leadership of a single leader, for the days of spiritual monarchies are over, nor for the leadership of exaggerated figureheads, but for the energetic initiatives of many co-operating personalities. I will not speculate where these leaders are now, in universities, in laboratories, in studies, in factories, in mines, in technical schools, but I have a firm belief that they will come to the call of our mighty opportunities.
