Just as the wave cannot exist for itself, but is ever a part of the heaving surface of the ocean, so must I never live my life for itself, but always in the experience which is going on around me. It is an uncomfortable doctrine which the true ethics whisper into my ear. You are happy, they say; therefore you are called upon to give much.

Never for a moment do we lay aside our mistrust of the ideals established by society, and of the convictions which are kept by it in circulation. We always know that society is full of folly and will deceive us in the matter of humanity. ... humanity meaning consideration for the existence and the happiness of individual human beings.

True philosophy must start from the most immediate and comprehensive fact of consciousness: "I am life that wants to live, in the midst of life that wants to live."

The way to true mysticism leads up through rational thought to deep experience of the world and of our will-to-live. We must all venture once more to be "thinkers," so as to reach mysticism, which is the only direct and the only profound world-view. We must all wander in the field of knowledge to the point where knowledge passes over into experience of the world. We must all, through thought, become religious.This rational thought must become the prevailing force among us, for all the valuable ideas that we need develop out of it. In no other fire than that of the mysticism of reverence for life can the broken sword of idealism be forged anew.

If rational thought thinks itself out to a conclusion, it arrives at something non-rational which, nevertheless, is a necessity of thought. This is the paradox which dominates our spiritual life. If we try to get on without this non-rational element, there result views of the world and of life which have neither vitality nor value.

The restoration of our world-view can come only as a result of inexorably truth-loving and recklessly courageous thought. Such thinking alone is mature enough to learn by experience how the rational, when it thinks itself out to a conclusion, passes necessarily over into the non-rational. World- and life-affirmation and ethics are non-rational. They are not justified by any corresponding knowledge of the nature of the world, but are the disposition in which, through the inner compulsion of our will-to-live, we determine our relation to the world. What the activity of this disposition of ours means in the evolution of the world, we do not know. Nor can we regulate this activity from outside; we must leave entirely to each individual its shaping and its extension. From every point of view, then, world- and life-affirmation and ethics are non-rational, and we must have the courage to admit it.

From my youth onwards, I have felt sure that all thought which thinks itself out to an issue ends in mysticism. In the stillness of the African jungle I have been able to work out this thought and give it expression.

Ethics, too, are nothing but reverence for life. That is what gives me the fundamental principle of morality, namely, that good consists in maintaining, promoting, and enhancing life, and that destroying, injuring, and limiting life are evil.

Reverence for life, veneratio vitæ, is the most direct and at the same time the profoundest achievement of my will-to-live. In reverence for life my knowledge passes into experience. The simple world- and life-affirmation which is within me just because I am will-to-live has, therefore, no need to enter into controversy with itself, if my will-to-live learns to think and yet does not understand the meaning of the world. In spite of the negative results of knowledge, I have to hold fast to world- and life-affirmation and deepen it. My life carries its own meaning in itself. This meaning lies in my living out the highest idea which shows itself in my will-to-live, the idea of reverence for life. With that for a starting-point I give value to my own life and to all the will-to-live which surrounds me, I persevere in activity, and I produce values.

World-view is a product of life-view, not vice versa.
