Renunciation of thinking is a declaration of spiritual bankruptcy.

Ethics is the activity of man directed to secure the inner perfection of his own personality.

Jesus as a concrete historical personality remains a stranger to our time, but His spirit, which lies hidden in His words, is known in simplicity, and its influence is direct.

Your life is something opaque, not transparent, as long as you look at it in an ordinary human way. But if you hold it up against the light of God's goodness, it shines and turns transparent, radiant and bright. And then you ask yourself in amazement: Is this really my own life I see before me?

Any religion or philosophy which is not based on a respect for life is not a true religion or philosophy.

Soldiers' graves are the greatest preachers of peace.

Thought cannot avoid the ethical or reverence and love for all life. It will abandon the old confined systems of ethics and be forced to recognize the ethics that knows no bounds. But on the other hand, those who believe in love for all creation must realize clearly the difficulties involved in the problem of a boundless ethic and must be resolved not to veil from humankind the conflicts which this ethic will involve us, but allow us really to experience them. To think out in every implication the ethic of love for all creation this is the difficult task which confronts our age.
