Edward Abbey, from Desert Solitaire, about the semi-myth that you can survive in the desert by cutting open a cactus and drinking the water inside.
When you reach this point, you are doomed. Far better to have stayed at home with the TV and a case of beer. If the happy thought arrives too late, crawl into the shade and contemplate the lonely sky. See those big black scrawny wings far above, waiting? Comfort yourself with the reflection that within a few hours, if all goes as planned, your human flesh will be working its way through the gizzard of a buzzard, your essence transfigured into the fierce greedy eyes and unimaginable consciousness of a turkey vulture. Whereupon you, too, will soar on motionless wings high over the ruck and rack of human suffering. For most of us a promotion in grade, for some the realization of an ideal.+++
