Adults have not understood children or adolescents and they are, as a consequence, in continual conflict with them.

The aim of education should not be to teach how to use human energies to improve the environment, for we are finally beginning to realize that the cornerstone of education is the development of the human personality, and that in this regard education is of immediate importance for the salvation of mankind.

A humankind abandoned in its earlier formative stage becomes its own greatest threat to survival.

The real preparation for education is a study of one's self. The training of the teacher...is something far more than a learning of ideas. It includes the training of character; it is a preparation of the spirit.

Never help a child with a task that they feel they can complete themselves.

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 ancient saying, "There is nothing in the intellect which was not first in some way in the senses," and senses being explorers of the world, opens the way to knowledge.
