Truth has no special time of its own. Its hour is now - always.

Living truth is that alone which has its origins in thinking. Just as a tree bears year after year the same fruit which is each year new, so must all permanently valuable ideas be continually born again in thought.

Whatever you have received more than others-in health, in talents, in ability, in success, in a pleasant childhood, in harmonious conditions of home life-all this you must not take to yourself as a matter of course.

Reverence for Life affords me my fundamental principle of morality, namely, that good consists in maintaining, assisting, and enhancing life and that to destroy, harm, or to hinder life is evil. Affirmation of the world - that is affirmation of the will to live, which appears in phenomenal forms all around me - is only possible for me in that I give myself out for other life.
