Respect all the reasonable forms of activity in which the child engages and try to understand them.

It is not the child as a physical but as a psychic being that can provide a strong impetus to the betterment of mankind. It is the spirit of the child that can determine the course of human progress and lead it perhaps even to a higher form of civilization.

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

Joy is the evidence of inner growth.

Growth comes from activity, not from intellectual understanding.

It is well to cultivate a friendly feeling towards error, to treat it as a companion inseparable from our lives, as something having a purpose, which it truly has.

With younger children the greatest reward is to be able to pass on to a new stage in each subject. It is a punishment to a young child not to be allowed to use the apparatus but to sit still and do nothing.
