What a distressing contrast there is between the radiant intelligence of the child and the feeble mentality of the average adult.

The voice of the intellect is soft one, but it does not rest until it has gained a hearing. Ultimately, after endless rebuffs, it succeeds. This is one of the few points in which one may be optimistic about the future of mankind.
