Mental development must be connected with movement and be dependent on it. It is vital that educational theory and practice should be informed by that idea.

Plainly, the environment must be a living one, directed by a higher intelligence, arranged by an adult who is prepared for his mission.

It is not enough for the teacher to love the child. She must first love and understand the universe. She must prepare herself, and truly work at it.

The teacher must derive not only the capacity, but the desire, to observe natural phenomena. The teacher must understand and feel her position of observer: the activity must lie in the phenomenon.

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 is endowed with unknown powers, which can guide us to a radiant future. If what we really want is a new world, then education must take as its aim the development of these hidden possibilities.

The child is an enigma… He has the highest potentialities, but we do not know what he will be.
