A child needs freedom within limits.

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

It is not the child as a physical but as a psychic being that can provide a strong impetus to the betterment of mankind. It is the spirit of the child that can determine the course of human progress and lead it perhaps even to a higher form of civilization.

To stimulate life, leaving it then free to develop, to unfold, herein lies the first task of the teacher.

With younger children the greatest reward is to be able to pass on to a new stage in each subject. It is a punishment to a young child not to be allowed to use the apparatus but to sit still and do nothing.

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.

Children become like the things they love.
