“The redemption of mankind, by whatever means, was assured for the future. It was, in fact, assured by the future.”
Faith and History: A Comparison of Christian and Modern Views of History (1949)
Context: The fact that the prevailing mood of modern culture was able to transmute the original pessimism of romanticism into an optimistic creed proves the power of this mood. Only occasionally the original pessimism erupts in full vigor, as in the thought of a Schopenhauer or Nietzsche. The subjugation of romantic pessimism, together with the transmutation of Marxist catastrophism establishes historical optimism far beyond the confines of modern rationalism. Though there are minor dissonances the whole chorus of modern culture learned to sing the new song of hope in remarkable harmony. The redemption of mankind, by whatever means, was assured for the future. It was, in fact, assured by the future.

Context: I think that it is a fallacy to suppose that helpful cooperation in the future will be assured by the attempted compulsion of an inflexible rule. Rather will such cooperation depend upon the fostering of firm friendships springing from an appreciation of community ideals, interests, and purposes, and such friendships are more likely to be promoted by freedom of conference than by the effort to create hard and fast engagements.

Context: To begin an affair of that kind now, and carry it on so long a time in form, is by no means a proper plan … whatever assurances I may give her in private of my esteem for her, or whatever assurances I may ask in return from her, depend on it — they must be kept in private. Necessity will oblige me to proceed in a method which is not generally thought fair; that of treating with a ward before obtaining the approbation of her guardian. I say necessity will oblige me to it, because I never can bear to remain in suspense so long a time. If I am to succeed, the sooner I know it, the less uneasiness I shall have to go through. If I am to meet with a disappointment, the sooner I know it, the more of life I shall have to wear it off: and if I do meet with one, I hope in God, and verily believe; it will be the last.
