It is the fate of every truth to be an object of ridicule when it is first acclaimed.

I still remain convinced that truth, love, peaceableness, meekness, and kindness are the violence which can master all other violence. The world will be theirs as soon as ever a sufficient number of people with purity of heart, with strength, and with perseverance think and live out the thoughts of love and truth, of meekness and peaceableness.

Affirmation of the world, which means affirmation of the will-to-live that manifests itself around me, is only possible if I devote myself to other life.

A man is ethical only when life, as such, is sacred to him.

Man is a clever animal who behaves like an imbecile.

To the truly ethical man, all of life is sacred, including forms of life that from the human point of view may seem lower than ours.

In the same way as the tree bears the same fruit year after year, but each time new fruit, all lastingly valuable ideas in thinking must always be reborn.
