In the modern world the pitch, it appears, has become smaller and smaller, the pitch of human understanding. Why is this so? Because of the lack of individual progress. As man is busy with mass-production the general tendency is to keep everybody on the same level of understanding. People all read the same newspapers as if they were afraid of ideas being unalike. So they remain all at the same pitch; and if any man has a tendency to go forward he is considered a dreamer, an eccentric, strange. There is no encouragement for individual development, and therefore society keeps the progress of the whole within certain limits and does not allow it to develop further.
