Play is the work of the child.

Preventing war is the work of politicians, establishing peace is the work of educationists.

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

Only when the child is able to identify its own center with the center of the universe does education really begin.

A new education from birth onwards must be built up. Education must be reconstructed and based on the law of nature and not on the preconceived notions and prejudices of adult society.

No social problem is as universal as the oppression of the child ... No slave was ever so much the property of his master as the child is of his parent ... Never were the rights of man ever so disregarded as in the case of the child.

The activity of the child has always been looked upon as an expression of his vitality.
