I am by nature a person suspicious of the economic machine that feeds me. And yet I am a captive of that economic machine, and my mind is structured by its lessons and demands. I consume its wealth with zest. I drive a truck, watch a color television, and write on a computer, but I cannot overcome the feeling that these objects and the industrial culture that produced them are temporary things, a kind of fat beast feeding on the bounty of the earth that will starve to death within the next century, or at least be severely diminished.
