Let us treat them [children], therefore, with all the kindness which we would wish to help to develop in them.

A child is mysterious and powerful; And contains within himself the secret of human nature.

Do not offer the child the content of the mind, but the order for that content.

How often is the soul of man - especially in childhood - deprived because he is not allowed to come in contact with nature.

Free choice is one of the highest of all the mental processes.

To have a vision of the cosmic plan, in which every form of life depends on directed movements which have effects beyond their conscious aim, is to understand the child's work and be able to guide it better.

Growth and psychic development are therefore guided by: the absorbent mind, the nebulae and the sensitive periods, with their respective mechanisms. It is these that are hereditary and characteristic of the human species. But the promise they hold can only be fulfilled through the experience of free activity conducted in the environment.
