God always takes the simplest way.

All these primary impulses, not easily described in words, are the springs of man's actions.

The importance of a problem should not be judged by the number of pages devoted to it.

Teaching should be such that what is offered is perceived as a valuable gift and not as hard duty. Never regard study as duty but as the enviable opportunity to learn to know the liberating influence of beauty in the realm of the spirit for your own personal joy and to the profit of the community to which your later work belongs.

Experts are just trained dogs.

Thought is the organizing factor in man, intersected between the causal primary instincts and the resulting actions.

You can never solve a problem on the level on which it was created.
