Who has fully realized that history is not contained in thick books but lives in our very blood?

Man is not a machine that can be remodelled for quite other purposes as occasion demands, in the hope that it will go on functioning as regularly as before but in a quite different way. He carries his whole history with him; in his very structure is written the history of mankind.

Who looks outside, dreams; who looks inside, awakes.

One looks back with appreciation to the brilliant teachers, but with gratitude to those who touched our human feelings. The curriculum is so much necessary raw material, but warmth is the vital element for the growing plant and for the soul of the child.

The healthy man does not torture others - generally it is the tortured who turn into torturers.

A man who has not passed through the inferno of his passions has never overcome them.
