But also we must realize that the lessons of history cannot ever be accepted blindly. The "principles of the founders" apply to us only in modified form; for the world in which we live today is different from any world which has ever been before, and the world tomorrow will be different yet. We are the makers of it, and the masters of it, and what it will be depends to some extent upon our choice. In fact, that is the most important lesson of all for us to learn; the final purpose of all our thought about the world is to enable us to make it a happier and a better world for ourselves and our posterity to live in. CHAPTER L ARISTOCRACY AND DEMOCRACY (Discusses the idea of superior classes and races, and whether there is a natural basis for such a doctrine.) In the letters of Thomas Jefferson is found the following passage: "All eyes are open or opening to the rights of man. The general spread of the light of science has already laid open to every view the palpable truth that the mass of mankind has not been born with saddles on their backs, nor a favored few booted and spurred, ready to ride them legitimately, by the grace of God." This, which Jefferson, over a hundred years ago, described as a "palpable truth," is still a long way from prevailing in the world. We are trying in this book not to take anything for granted, so we do not assume this truth, but investigate it; and we begin by admitting that there are many facts which seem to contradict it, and which make it more difficult of proof than Jefferson realized. It is not enough to point out the lack of saddles on the backs, and of boots and spurs on the feet of newly born infants; for the fact is that men are not exploited because of saddles, nor is the exploiting accomplished by means of boots and spurs. It is done by means of gold and steel, banks and credit systems, railroads, machine-guns and battleships. And while it is not true that certain races and classes are born with these things on them, they are born to the possession of them, and the vast majority of mankind are without them all their lives, and without the ability to use them even if they had them.
