Public Opinion

by Walter Lippmann

The point is that the accepted patriotic code assumes one kind of human nature, the commercial code another. And the codes are probably founded on true expectations to this extent, that when a man adopts a certain code he tends to exhibit the kind of human nature which the code demands. That is one reason why it is so dangerous to generalize about human nature. A loving father can be a sour boss, an earnest municipal reformer, and a rapacious jingo abroad. His family life, his business career, his politics, and his foreign policy rest on totally different versions of what others are like and of how he should act. These versions differ by codes in the same person, the codes differ somewhat among persons in the same social set, differ widely as between social sets, and between two nations, or two colors, may differ to the point where there is no common assumption whatever. That is why people professing the same stock of religious beliefs can go to war. The element of their belief which determines conduct is that view of the facts which they assume.
