No one who cares about the human future can afford to ignore E.O. Wilson's book. On Human Nature begins a new phase in the most important intellectual controversy of this generation: Is human behavior controlled by the species' biological heritage? Does this heritage limit human destiny? With characteristic pugency and simplicity of style, the author of Sociobiology challenges old prejudices and current misconceptions about the nature-nurture debate. In his new preface E. O. Wilson reflects on how he came to write this book: how The Insect Societies led him to write Sociobiology, and how the political and religious uproar that engulfed that book persuaded him to write another book that would better explain the relevance of biology to the understanding of human behavior.
