"Not everything we feel is felt powerfully enough to send a message to the brain; the rest of the sensations just wash over us, telling us nothing. Much is lost in translation, or is censored, and in any case our nerves don’t all fire at once. Some of them remain silent while others respond. This makes our version of the world somewhat simplistic, given how complex the world is. The body’s quest isn’t for truth, it’s for survival."

“We tend to see our distant past through a reverse telescope that compresses it: a short time as hunter-gatherers, a long time as "civilized" people. But civilization is a recent stage of human life, and, for all we know, it may not be any great achievement. It may not even be the final stage. We have been alive on this planet as recognizable humans for about two million years, and for all but the last two or three thousand we’ve been hunter-gatherers. We may sing in choirs and park our rages behind a desk, but we patrol the world with many of a hunter-gatherer’s drives, motives, and skills. These aren’t knowable truths. Should an alien civilization ever contact us, the greatest gift they could give us would be a set of home movies: films of our species at each stage in our evolution.”

“What would dawn have been like, had you awakened? It would have sung through your bones. All I can do this morning is let it sing through mine.”

“I don't want to get to the end of my life and find that I just lived the length of it. I want to live the width of it as well.”

“Consciousness, the great poem of matter, seems so unlikely, so impossible, and yet here we are with our loneliness and our giant dreams.”

“But we rarely taste the real thing. The vanilla flavoring we buy in the spice section of grocery stores, the vanilla we find in most of our ice creams, cakes, yogurts, and other foods, as well as in shampoos and perfumes, is an artificial flavor created in laboratories and mixed with alcohol and other ingredients. Marshall McLuhan once warned us that we were drifting so far away from the real taste of life that we had begun to prefer artificiality, and were becoming content with eating the menu descriptions rather than the food.”

“Why humans feel pain has been the subject of theological debate, philosophical schisms, psychoanalytical edicts, and mumbo jumbo for centuries. Pain was the punishment for wrongdoing in the Garden of Eden. Pain was the price one paid for not being morally perfect. Pain was a self-affliction brought about by sexual repression. Pain was dished out by vengeful gods, or was the result of falling out of harmony with nature…The purpose of pain is to warn the body about possible injury. Millions of free nerve endings alarm us; whenever they’re hit, we feel pain.”
