The human race is divided into two sharply differentiated and mutually antagonistic classes, almost two genera- a small minority that plays with ideas and is capable of taking them in, and a vast majority that finds them painful, and is thus arrayed against them, and against all who have traffic with them. The intellectual heritage of the race belongs to the minority, and to the minority only. The majority has no more to do with it than it has to do with ecclesiastic politics on Mars. In so far as that heritage is apprehended, it is viewed with enmity. But in the main it is not apprehended at all.
