“What happens when an animal or person dies? Something seems to have departed--something like a vital spark that makes the difference between life and death. In the nineteenth century, philosophers believed that there really was such a thing and called it the élan vital, or vital spirit. But when twentieth century science began to unravel the mysteries of how living things work and reproduce, the idea was abandoned and people now accept that there is nothing more to being alive than complex, interrelated, biological functions.”

“The whole difference between the nineteenth century and the twentieth century could be summed up in two words, graveyard and cemetery.”

“Spinoza spoke of vitality as the purest virtue, the only virtue. The drive to persist, to flourish, he said, is the absolute quality shared by all living beings. What happens, however, when vitality is inverted, and instead of flourishing, one is driven to eat oneself alive?”

“From behind the wheel, I learn the difference between a eulogy and an elegy, and discover which is more vital, in life and in death.”

“In the new century science will defeat famine, boredom, and the plague, but . . . vital knowledge will become so elevated that nobody will know how anything works. . . . the good news is that everybody will be empowered; the bad news is nobody will understand why.”

“Things which sound like platitudes become vital, living and powerful when you have to learn them in dark tunnels.”
