The task of the educator lies in seeing that the child does not confound good with immobility, and evil with activity, as often happens in old-time discipline . . . A room in which all the children move about usefully, intelligently, and voluntarily, without committing any rough or rude act, would seem to me a classroom very well disciplined indeed.

The child’s progress does not depend only on his age, but also on being free to look around him.

The hands are the instruments of man’s intelligence.

What is a scientist?... We give the name scientist to the type of man who has felt experiment to be a means guiding him to search out the deep truth of life, to lift a veil from its fascinating secrets, and who, in this pursuit, has felt arising within him a love for the mysteries of nature, so passionate as to annihilate the thought of himself.

We teachers can only help the work going on, as servants wait upon a master.

Love and the hope of it are not things one can learn; they are a part of life's heritage.

The essential thing is to arouse such an interest that it engages the child’s whole personality.
