The Parable of the Frogs

 In the face of what seems to be biologically driven activity, reason doesn’t have much of a chance. An experiment with frogs some years ago demonstrated this quite clearly. They were wired up with electrodes in the pleasure center of the brain, and could stimulate that center–i.e., create a “rush”–by pressing a metal bar. Not only did the frogs keep pressing the bar over and over again, but they didn’t stop even when their legs were cut off with a pair of shears!
