Conventions which camouflage a man's true feelings are a spiritual lie which help him adapt himself to the organized deviations of society.

The unknown energy that can help humanity is that which lies hidden in the child.

There is in every child a painstaking teacher so skillful that he obtains identical results in all children in all parts of the world. The only language men ever speak perfectly is the one they learn in babyhood, when no one teaches them anything.

Only practical work and experience lead the young to maturity.

Happiness is not the whole aim of education. A man must be independent in his powers and character; able to work and assert his mastery over all that depends on him.

The greatest sign of success for a teacher...is to be able to say, "The children are now working as if I did not exist."

Joy is the evidence of inner growth.
