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.

There are many things which no teacher can convey to a child of three, but a child of five can do it with ease.

Nothing is created or destroyed in nature.

The child seeks for independence by means of work; an independence of body and mind.

Discipline must come through liberty. . . . We do not consider an individual disciplined only when he has been rendered as artificially silent as a mute and as immovable as a paralytic. He is an individual annihilated, not disciplined.
