Readers of _You Can't Do Business With Hitler_ will not need to be convinced again that the two systems--his and ours--are mutually incompatible. Fortunately for us, they are also mutually destructive. The basis of fascism is, as I have noted, the feudal hope of a fixed unchangeable form of society which will last forever; the basis of democracy is change (which we call progress). Hitler announces that nazism will last a thousand years; the Japanese assert that their society has lasted longer; and the voice of Mussolini, when it used to be heard, spoke of Ancient Rome. We who are too impatient of the past, and need to understand our tradition, are at any rate aware of one thing--it is a tradition of change. (Jefferson to Lincoln to Theodore Roosevelt--the acceptance of change, even of radical change, is basic in American history.) We might tolerate the tactics of fascism; the racial hatred, the false system of education, the attack on religion, all might pass if they weren't part of the great strategic process of the fascists, which is our mortal enemy, as our process is theirs. They exclude and we penetrate; they have to _destroy_ liberty in order to control making and buying and selling and using steel and bread and radios, and we have to _create_ liberty in order to create more customers for more things. They have to suppress dissent because dissent means difference which no feudal system can afford; we have to encourage criticism because only free inquiry destroys error and discovers new and useful truths. These hostile actions make us enemies because our penetration will not accept the Axis wall thrown up around nations normally free and friendly to us; and the Axis must make us into fascists because there can be no exceptions in a system dedicated to conformity. The whole world must accept a world-system.
