“Reverence for human personality is the beginning of wisdom, in every social question, but above all in education.”

“No man is fit to educate unless he feels each pupil an end in himself, with his own rights and his own personality, not merely a piece in a jigsaw puzzle, or a soldier in a regiment, or a citizen in a State. Reverence for human personality is the beginning of wisdom, in every social question but above all in education.”

“Fear is the main source of superstition, and one of the main sources of cruelty. To conquer fear is the beginning of wisdom.”

“Freedom in education has many aspects. There is first of all freedom to learn or not to learn. Then there is freedom as to what to learn. And in later education there is freedom of opinion.”

“There lies before us, if we choose, continual progress in happiness, knowledge and wisdom. Shall we instead choose death, because we cannot forget our quarrels? I appeal as a human being to human beings; remember your humanity, and forget the rest.”

“Clarity, above all, has been my aim.”

“The ideal of an “all-round” education is out of date; it has been destroyed by the progress of knowledge.”
