tion of the number of aspects we are prepared to discover, plus the habit of discounting our expectations. Where to the ignoramus all things look alike, and life is just one thing after another, to the specialist things are highly individual. For a chauffeur, an epicure, a connoisseur, a member of the President's cabinet, or a professor's wife, there are evident distinctions and qualities, not at all evident to the casual person who discusses automobiles, wines, old masters, Republicans, and college faculties.
But in our public opinions few can be expert, while life is, as Mr. Bernard Shaw has made plain, so short. Those who are expert are so on only a few topics. Even among the expert soldiers, as we learned during the war, expert cavalrymen were not necessarily brilliant with trench-warfare and tanks. Indeed, sometimes a little expertness on a small topic may simply exaggerate our normal human habit of trying to squeeze into our stereotypes all that can be squeezed, and of casting into outer darkness that which does not fit.
Whatever we recognize as familiar we tend, if we are not very careful, to visualize with the aid of images already in our mind. Thus in the American view of Progress and Success there is a definite picture of human nature and of society. It is the kind of human nature and the kind of society which logically produce the kind of progress that is regarded as ideal. And then, when we seek to describe or explain actually successful men, and events that have really happened, we read back into them the qualities that are presupposed in the stereotypes.
