“Tomorrow is the winter solstice, the longest night of the year. But few of us will turn off the lights long enough to notice. There’s no getting away from the light. There are fluorescent lights and halogen lights, stadium lights, streetlights, stoplights, headlights and billboard lights. There are night lights to stand sentinel in hallways, and the lit screens of cellphones to feed our addiction to information, even in the middle of the night. No wonder we have trouble sleeping. The lights are always on.
“In the modern world, petroleum may drive our engines but our consciousness is driven by light. And what it drives us to is excess, in every imaginable form.”
