Men make the attempt. The peoples of the earth assemble and write a treaty which keeps the chief democratic nations on the continent of Europe armed against each other, which provides endless subjects of dispute among the smaller countries; and they sign a covenant which the unanimous opinion of mankind rejects as an effective safeguard against future wars and which many regard as dividing the earth into two hostile camps. "It was humanity's failure," declares General Smuts. "There will always be war," asserts President Harding, calling a conference not to end war but to lessen the cost of preparing for war. Not only has material progress failed to produce peace as its by-product, but moral progress has failed to produce peace as its deliberate product. And Progress is in reality moving forward to wars more deadly and more ruinous than the last. Weapons were developed toward the end of the Great War capable of vastly worse havoc than any used during its course. And only a beginning has been made. If we may come to use the power that holds atoms together in the driving of engines, we may also use it in war to blast whole cities from the face of the earth. Conquest of the air means larger bombs from the air. Greater knowledge of chemistry means industrial advancement and also deadlier poison gases. Material gains bring compensating material ills or the possibility of them. Even the material gains, great as they have been, seem somewhat smaller today than they once were thought to be. In our most optimistic moments before the war we had the pleasant illusion of steadily decreasing hours of labor and steadily lowering costs. Men had worked twelve, ten, and finally eight hours a day, and it was predicted that this process would go on until six, perhaps four hours a day would be sufficient to supply the needs of the race. We paid five cent fares on the street cars and were hopeful that they would become three cent fares; three cents was established by law in many cities as the maximum charge. The railroads collected a little over two cents a mile for carrying passengers and in many states statutes were enacted establishing two cents a mile as the legal rate. We were impressed by striking examples of lowering prices, in the automobile industry for example, and were confident that this was the rule of modern life. Prices, except of food products, were steadily decreasing; there might be an end to this movement but we were nowhere near the end. The wonders of modern inventions, and if not these, the economics of concentrated organization, and if not these, the use of by-products, were steadily lowering costs. The standard of living was rising. What was the rich man's luxury in one generation was the poor man's necessity in the next. It would always be so. That was Progress.
