The greatest step forward in human evolution was made when society began to help the weak and the poor, instead of oppressing and despising them.

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.

No one can be free unless he is independent. Therefore, the first active manifestations of the child's individual liberty must be so guided that through this activity he may arrive at independence.

The whole of mankind is one and only one, one race, one class and one society.

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

We must help the child to act for himself, will for himself, think for himself; this is the art of those who aspire to serve the spirit.

The work of education is divided between the teacher and the environment.
