"Encouragement is oxygen to the soul. Good work can never be expected from a worker without encouragement. No one ever climbed spiritual heights without it. No one ever lived without it."

The general notions about human understanding...which are illustrated by discoveries in atomic physics are not in the nature of things wholly unfamiliar, wholly unheard of, or new. Even in our own culture, they have a history, and in Buddhist and Hindu thought a more considerable and central place. What we shall find is an exemplification, an encouragement, and a refinement of old wisdom.
