Beginning in the late 19th century, the availability of cheap, effective lighting extended the range of waking human consciousness, effectively adding more hours onto the day — for work, for entertainment, for discovery, for consumption; for every activity except sleep, that nightly act of renunciation. Darkness was the only power that has ever put the human agenda on hold.

In centuries past, the hours of darkness were a time when no productive work could be done. Which is to say, at night the human impulse to remake the world in our own image — so that it served us, so that we could almost believe the world and its resources existed for us alone — was suspended. The night was the natural corrective to that most persistent of all illusions: that human progress is the reason for the world.

Advances in science, industry, medicine and nearly every other area of human enterprise resulted from the influx of light. The only casualty was darkness, a thing of seemingly little value. But that was only because we had forgotten what darkness was for. In times past people took to their beds at nightfall, but not merely to sleep. They touched one another, told stories and, with so much night to work with, woke in the middle of it to a darkness so luxurious it teased visions from the mind and divine visitations that helped to guide their course through life. Now that deeper darkness has turned against us. The hour of the wolf we call it — that predatory insomnia that makes billions for big pharma. It was once the hour of God.

There is, of course, no need to fear the dark, much less prevail over it. Not that we could. Look up in the sky on a starry night, if you can still find one, and you will see that there is a lot of darkness in the universe. There is so much of it, in fact, that it simply has to be the foundation of all that is. The stars are an anomaly in the face of it, the planets an accident. Is it evil or indifferent? I don’t think so. Our lives begin in the womb and end in the tomb. It’s dark on either side.

We’ve rolled back the night so far that soon we will come full circle and reach the dawn of the following day. And where will that leave us? In a world with no God and no wolf either — only unrelenting commerce and consumption, information and media ... and light. We need a rest from ourselves that only a night like the winter solstice can give us. And the earth, too, needs that rest. The only thing I can hope for is that, if we won’t come to our senses and search for the darkness, on nights like these, the darkness will come looking for us.
