From the current issue of Newsweek: "[Evolutionary psychology] holds that we all carry genes that led to reproductive success in the Stone Age, and that as a result . . . every human behavior is 'adaptive'--that is, helpful to reproduction. But as Harvard biologist Marc Hauser now concedes, evidence is 'sorely missing' that language, morals and many other human behaviors exist because they help us mate and reproduce."
Thank God for common sense and empirical observation! Maybe "Mr. Simply-Survive-and-Reproduce" can now join the Purely Rational Man of traditional economics, the Stimulus-Response Zombie of behavioral psychology, the Penis-Envying Woman of Freudian thought, and the Class-Conscious Robot of Marxism in the trashcan of history. What is it that makes otherwise intelligent people fall for such simplistic accounts of human behavior? We are immensely complex creatures, people! The only remotely successful reductions of human behavior to a single principle have been those that are so broadly-conceived that they can stand for just about anything (e.g., Spinoza's conatus, or Nietzsche's "Will to Power"). And I would argue that even those fail to account for the full range of human aesthetics, spirituality, and sense of awe faced with the infinite (though Spinoza tried to account for this in the fifth section of his Ethics, the part least satisfying to commentators today). Let's just admit that there is a great deal that is mysterious and unpredictable about us, and that the writers, poets, and psychologists of the world are not out of a job yet.
