Wilson, author of The Diversity of Life and winner of two Pulitzer prizes, to describe what he believes is our innate affinity for the natural world. In his landmark book Biophilia, he examined how our tendency to focus on life and lifelike processes might be a biologically based need, integral to our development as individuals and as a species. The idea has caught the imagination of diverse thinkers. The Biophilia Hypothesis brings together the views of some of the most creative scientists of our time, each attempting to amplify and refine the concept of biophilia. The various perspectives - psychological, biological, cultural, symbolic, and aesthetic - frame the theoretical issues by presenting empirical evidence that supports or refutes the hypothesis. Numerous examples illustrate the idea that biophilia and its converse, biophobia, have a genetic component: people develop fear and even full-blown phobias of snakes and spiders with very little negative reinforcement, while more threatening modern artifacts - knives, guns, automobiles - rarely elicit such a response; people would rather look at water, green vegetation, or flowers than built structures of glass and concrete; and the development of language, myth, and thought appears to be greatly dependent on the use of natural symbols, particularly animals. The biophilia hypothesis, if substantiated, provides a powerful argument for the conservation of biological diversity. More important, it implies serious consequences for our well-being as society becomes further estranged from the natural world. Relentless environmental destruction could have a significant impact on our quality of life, not just materially but psychologically and even spiritually.
