The child is the spiritual builder of mankind, and obstacles to his free development are the stones in the wall by which the soul of man has become imprisoned.

It is almost possible to say that there is a mathematical relationship between the beauty of his surroundings and the activity of the child; he will make discoveries rather more voluntarily in a gracious setting than in an ugly one.

The child can only develop fully by means of experience in his environment. We call such experience 'work'.

Concentration is the key that opens up to the child the latent treasures within him.

Today, however, those things which occupy us in the field of education are the interests of humanity at large and of civilization, and before such great forces we can recognize only one country-the entire world.

Every great cause is born from repeated failures and from imperfect achievements.

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.
