From the website Brain Pickings, these excerpts from a lecture by Vladimir Nabokov. He says that optimism is not a luxury of the privileged, but at the core of everyone’s survival:

The second result is that the irrational belief in the goodness of man… becomes something much more than the wobbly basis of idealistic philosophies. It becomes a solid and iridescent truth. This means that goodness becomes a central and tangible part of one’s world, which world at first sight seems hard to identify with the modern one of newspaper editors and other bright pessimists, who will tell you that it is, mildly speaking, illogical to applaud the supremacy of good at a time when something called the police state, or communism, is trying to turn the globe into five million square miles of terror, stupidity, and barbed wire. And they may add that it 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.

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 immortal 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.

I needed to read those words today. I am so bound to the world as it comes to me through my laptop. It is my vocation to read, to watch, to contemplate, and to write about it. But it is far, far too easy, especially if you have a temperament like mine, to get lost in the darkness, and to lose sight of the straight path that God has laid before us, and that many people with lesser powers than our own still manage to stagger along it, rejoicing and not losing their way despite it all.

Today is the Feast of St. Nicholas. This afternoon, when the children come home from school, we are going to buy our family Christmas tree. Little makes me happier than watching my children run among the trees in the field, and choose the right one for our house. This is how I know the world to be good.
