Every pampered child becomes a hated child.... There is no greater evil than the pampering of children.

What is courage? Courage is the willingness to risk failure...There is only one danger I find in life, and that, indeed, is a real one. You may take too many precautions.

There is a courage of happiness as well as a courage of sorrow.

To all those who walk the path of human cooperation war must appear loathsome and inhuman.

An educator's most important task, one might say his holy duty, is to see to it that no child is discouraged at school, and that a child who enters school already discouraged regains his self-confidence through his school and his teacher. This goes hand in hand with the vocation of the educator, for education is possible only with children who look hopefully and joyfully upon the future.

The science of the mind can only have for its proper goal the understanding of human nature by every human being, and through its use, brings peace to every human soul.

Courage is not an ability one either possess or lacks. Courage is the willingness to engage in a risk-taking behavior regardless of whether the consequences are unknown or possibly adverse. We are capable of courageous behavior provided we are willing to engage in it. Given that life offers few guarantees, all living requires risk-taking.
