“Nothing but the cross of Christ can so startle the spiritual nature from its torpor, as to make it an effectual counterpoise to the debasing and sensual tendencies of the race. Favored by temperament and education, individuals may measurably escape; but if the race is to triumph in the conflict between the flesh and the spirit, between the lower propensities and the higher nature, they must, as Constantine is said to have done, see the cross, and on it the motto, "In hoc signo vinces."”

Paris Review interview (1958)
Context: No one is without Christianity, if we agree on what we mean by that word. It is every individual’s individual code of behavior by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol — cross or crescent or whatever — that symbol is man’s reminder of his duty inside the human race. Its various allegories are the charts against which he measures himself and learns to know what he is. It cannot teach a man to be good as the textbook teaches him mathematics. It shows him how to discover himself, evolve for himself a moral codes and standard within his capacities and aspirations, by giving him a matchless example of suffering and sacrifice and the promise of hope.

The Foundations of the Nineteenth Century (Die Grundlagen des neunzehnten Jahrhunderts) (1899)

Context: Novelists when they write novels tend to take an almost godlike attitude toward their subject, pretending to a total comprehension of the story, a man's life, which they can therefore recount as God Himself might, nothing standing between them and the naked truth, the entire story meaningful in every detail. I am as little able to do this as the novelist is, even though my story is more important to me than any novelist's is to him — for this is my story; it is the story of a man, not of an invented, or possible, or idealized, or otherwise absent figure, but of a unique being of flesh and blood. Yet, what a real living human being is made of seems to be less understood today than at any time before, and men — each one of whom represents a unique and valuable experiment on the part of nature — are therefore shot wholesale nowadays. If we were not something more than unique human beings, if each one of us could really be done away with once and for all by a single bullet, story telling would lose all purpose. But every man is more than just himself; he also represents the unique, the very special and always significant and remarkable point at which the world's phenomena intersect, only once in this way and never again. That is why every man's story is important, eternal, sacred; that is why every man, as long as he lives and fulfills the will of nature, is wondrous, and worthy of every consideration. In each individual the spirit has become flesh, in each man the creation suffers, within each one a redeemer is nailed to the cross.
Few people nowadays know what man is. Many sense this ignorance and die the more easily because of it, the same way that I will die more easily once I have completed this story.
