There is a strange envy of any kind of excellence which cannot be universal, except, of course, in the sphere of athletics and sport, where aristocracy is enthusiastically acclaimed. It seems that the average American is more capable of humility in regard to his muscles than in regard to his brain; perhaps this is because his admiration for muscle is more profound and genuine than his admiration of brains. The flood of popular scientific book in America in inspired partly, though of course not wholly, by the unwillingness to admit that there is anything in science which only experts can understand. The idea that a special training may be necessary to understand, say, the theory of relativity, causes a sort of irritation, although nobody is irritated by the fact that a special training is necessary in order to be a first-rate football player.
