“Our Yes towards life from the very beginning carries within it the Divine No which breaks forth from the antithesis and points away from what now was the thesis to the original and final synthesis. The No is not the last and highest truth, but the call from home which comes in answer to our asking for God in the world.”

Light (1919), Ch. XXIII - Face To Face
Context: Only the idolatrous and the weak have need of illusion as of a remedy. The rest only need see and speak.
She smiles, vague as an angel, hovering in the purity of the evening between light and darkness. I am so near to her that I must kneel to be nearer still. I kiss her wet face and soft lips, holding her hand in both of mine.
Yes, there is a Divinity, one from which we must never turn aside for the guidance of our huge inward life and of the share we have as well in the life of all men. It is called the truth.

Chiamo principio della morte tutto il corso della vita cominciando al nostro nascimento, dal quale cominciamo a morire, e per momenti di tempo andiamo ogni giorno al nostro fine.

1960s, Where Do We Go from Here: Chaos or Community? (1967)
Context: Communism forgets that life is individual. Capitalism forgets that life is social, and the kingdom of brotherhood is found neither in the thesis of communism nor the antithesis of capitalism but in a higher synthesis. It is found in a higher synthesis that combines the truths of both. Now, when I say question the whole society, it means ultimately coming to see that the problem of racism, the problem of exploitation, and the problem of war are all tied together. These are the triple evils that are interrelated.

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: 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. From an inner necessity, I exert myself in producing values and practising ethics in the world and on the world even though I do not understand the meaning of the world. For in world- and life-affirmation and in ethics I carry out the will of the universal will-to-live which reveals itself in me. I live my life in God, in the mysterious divine personality which I do not know as such in the world, but only experience as mysterious Will within myself.
Rational thinking which is free from assumptions ends therefore in mysticism. To relate oneself in the spirit of reverence for life to the multiform manifestations of the will-to-live which together constitute the world is ethical mysticism. All profound world-view is mysticism, the essence of which is just this: that out of my unsophisticated and naïve existence in the world there comes, as a result of thought about self and the world, spiritual self-devotion to the mysterious infinite Will which is continuously manifested in the universe.
