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 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.

The child who has felt a strong love for his surroundings and for all living creatures, who has discovered joy and enthusiasm in work, gives us reason to hope that humanity can develop in a new direction.
