IRRATIONAL STANDARDS, from "The Art of Literature and Commonsense" by Vladimir Nabokov:

. . .[I]t is one thing to beam at one's private universe in the snuggest nook of an unshelled and well-fed country and quite another to try and keep sane among crashing buildings in the roaring and whining night. But within the emphatically and unshakably illogical world which I am advertising as a home for the spirit, war gods are unreal not because they are conveniently remote in physical space from the reality of a reading lamp and the solidity of a fountain pen, but because I cannot imagine (and that is saying a good deal) such circumstances as might impinge upon the lovely and lovable world which quietly persists, whereas I can very well imagine that my fellow dreamers, thousands of whom roam the earth, keep to these same irrational and divine standards during the darkest and most dazzling hours of physical danger, pain, dust, death.

What exactly do these irrational standards mean? They mean the supremacy of the detail over the general, of the part that is more alive than the whole, of the little thing which a man observes and greets with a friendly nod of the spirit while the crowd around him is being driven by some common impulse to some common goal. I take my hat off to the hero who dashes into a burning house and saves his neighbor's child; but I shake his hand if he has risked squandering a precious five seconds to find and save, together with the child, its favorite toy. I remember a cartoon depicting a chimney sweep falling from the roof of a tall building and noticing on the way that a sign-board had one word spelled wrong, and wondering in his headlong flight why nobody had thought of correcting it. In a sense, we all are crashing to our death from the top story of our birth to the flat stones of the churchyard and wondering with an amoral Alice in Wonderland at the patterns of the passing wall. This capacity to wonder at trifles – no matter the imminent peril – these asides of the spirit, these footnotes in the volume of life are the highest forms of consciousness, and it is in this childishly speculative state of mind, so different from commonsense and its logic, that we know the world to be good.
