"Judging from the spiderwebs clinging to it, the emergency stairway was hardly ever used. To each web clung a small black spider, patiently waiting for its small prey to come along. Not that the spiders had any awareness of being "patient". A spider had no special skill other than building its web, and no lifestyle choice other than sitting still. It would stay in one place waiting for its prey until, in the natural course of things, it shriveled up and died. This was all genetically predetermined. The spider had no confusion, no despair, no regrets. No metaphysical doubt, no moral complications. Probably. Unlike me. I move,therefore I am."
