The Greeks possessed a knowledge of human nature we seem hardly able to attain to without passing through the strengthening hibernation of a new barbarism.

Education can counteract the natural tendency to do the wrong thing, but the inexorable succession of generations requires that the basis for this knowledge be constantly refreshed.

But now with the living conditions deteriorating, and with the sure knowledge that we are slated for destruction, we have been transformed into an implacable army of liberation.

Knowledge fills a large brain it merely inflates a small one.

An humble knowledge of thyself is a surer way to God than a deep search after learning.
