The task of the educator lies in seeing that the child does not confound good with immobility and evil with activity.

It is necessary, then, to give the child the possibility of developing according to the laws of his nature, so that he can become strong, and, having become strong, can do even more than we dared hope for him.

Growth is not merely a harmonious increase in size, but a transformation.

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.

When children come into contact with nature, they reveal their strength.

Under the urge of nature and according to the laws of development, though not understood by the adult, the child is obliged to be serious about two fundamental things ... the first is the love of activity... The second fundamental thing is independence.

The child becomes a person through work.
