Love as a concrete foundation for an authentically functional civilization requires the around-the-clock labors of forgiveness. Without it, Love fails, Friendship fails, Intelligence fails, Humanity: fails.
There is no such thing on earth as an uninteresting subject; the only thing that can exist is an uninterested person. Nothing is more keenly required than a defence of bores. When Byron divided humanity into the bores and bored, he omitted to notice that the higher qualities exist entirely in the bores, the lower qualities in the bored, among whom he counted himself. The bore, by his starry enthusiasm, his solemn happiness, may, in some sense, have proved himself poetical. The bored has certainly proved himself prosaic.
It is only great pain--that slow, sustained pain that takes its time, in which we are, as it were, burned with smoldering green firewood--that forces us philosophers to sink to our ultimate profundity and to do away with all the trust, everything good-natured, veil-imposing, mild and middling, on which we may have previously based our humanity. I doubt that such a pain makes us 'better'--but I know that it makes us deeper.
Forgiveness is the most effective way of dealing with arguments; altruism and forgiveness bring humanity together so that no conflict, however serious, will go beyond the bounds of what is truly human.
