The scientific control of life, by itself, creates more problems than it solves. The problem of international disarmament, for example, has been forced on us by the fear of that perdition to the suburbs of which our race has manifestly come through the misuse of scientific knowledge. Humanity is disturbed about itself because it has discovered that it is in possession of power enough to wreck the world. Never before did mankind have so much energy to handle. Multitudes of people, dubious as to whether disarmament is practical, are driven like shuttles back and forth between that doubt, upon the one side, and the certainty, upon the other, that armament is even less practical. The statisticians have been at work upon this last war and their figures, like the measurements of the astronomers, grow to a size so colossal that the tentacles of our imaginations slip off them when we try to grasp their size. The direct costs of this last war, which left us with more and harder difficulties than we had at the beginning, were about $186,000,000,000. Is that practical? At the beginning of 1922 almost all the nations in Europe, although by taxation they were breaking their people's financial backs, were spending far more than their income, and in the United States, far and away the richest nation on the planet, we faced an enormous deficit. Is that practical? In this situation, with millions of people unemployed, with starvation rampant, with social revolution stirring in every country--not because people are bad, not because they impatiently love violence, but because they cannot stand forever the social strain and economic consequence of war--what were we doing? We were launching battleships which cost $42,000,000 to build, which cost $2,000,000 a year to maintain and which, in a few years, would be towed out to sea to be used as an experimental target to try out some new armour-piercing shell. I wonder if our children's children will look back on that spectacle and call it practical. In 1912 the naval expenses of this country were about $136,000,000. In 1921 our naval expenses were about $641,000,000--approximately five times greater in nine years. So over all the earth war preparations were pyramiding with an ever accelerating momentum. And because any man can see that we must stop sometime, we have been trying desperately to stop now; to turn our backs upon this mad endeavour to build civilization upon a materialistic basis, bulwarked by physical force; to turn our faces toward spiritual forces, fair play, reasonable conference, good-will, service and co-operation.
