Nations are not communities and never have been. The history of any country, presented as the history of a family, conceals the fierce conflicts of interest (sometimes exploding, often repressed) between conquerors and conquered, masters and slaves, capitalists and workers, dominators and dominated in race and sex. And in such as world of conflict, a world of victims and executioners, it is the job of thinking people, as Albert Camus suggested, not to be on the side of the executioners.

Scholars, who pride themselves on speaking their minds, often engage in a form of self-censorship which is called "realism." To be "realistic" in dealing with a problem is to work only among the alternatives which the most powerful in society put forth. It is as if we are all confined to a, b, c, or d in the multiple choice test, when we know there is another possible answer. American society, although it has more freedom of expression than most societies in the world, thus sets limits beyond which respectable people are not supposed to think or speak. So far, too much of the debate on Vietnam has observed these limits.

If those in charge of our society — politicians, corporate executives, and owners of press and television — can dominate our ideas, they will be secure in their power.
