"Biophilia" is the term coined by Edward O. Wilson to describe what he believes is humanity's 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. That 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 variety of 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:

• fear, and even full-blown phobias of snakes and spiders are quick to develop with very little negative reinforcement, while more threatening modern artifacts -- knives, guns, automobiles -- rarely elicit such a response
• people find trees that are climbable and have a broad, umbrella-like canopy more attractive than trees without these characteristics
• people would rather look at water, green vegetation, or flowers than built structures of glass and concrete

Sustainable design has made great strides in recent years; unfortunately, it still falls short of fully integrating nature into our built environment. Through a groundbreaking new paradigm of "restorative environmental design," award-winning author Stephen R. Kellert proposes a new architectural model of sustainability.

In Building For Life, Kellert examines the fundamental interconnectedness of people and nature, and how the loss of this connection results in a diminished quality of life.

This thoughtful new work illustrates how architects and designers can use simple methods to address our innate needs for contact with nature. Through the use of natural lighting, ventilation, and materials, as well as more unexpected methodologies-the use of metaphor, perspective, enticement, and symbol-architects can greatly enhance our daily lives. These design techniques foster intellectual development, relaxation, and physical and emotional well-being. In the works of architects like Frank Lloyd Wright, Eero Saarinen, Cesar Pelli, Norman Foster, and Michael Hopkins, Kellert sees the success of these strategies and presents models for moving forward. Ultimately, Kellert views our fractured relationship with nature as a design problem rather than an unavoidable aspect of modern life, and he proposes many practical and creative solutions for cultivating a more rewarding experience of nature in our built environment.

Scientists, theologians, and the spiritually inclined, as well as all those concerned with humanity's increasingly widespread environmental impact, are beginning to recognize that our ongoing abuse of the earth diminishes our moral as well as our material condition. Many people are coming to believe that strengthening the bonds among spirituality, science, and the natural world offers an important key to addressing the pervasive environmental problems we face.

The Good in Nature and Humanity brings together 20 leading thinkers and writers -- including Ursula Goodenough, Lynn Margulis, Dorion Sagan, Carl Safina, David Petersen, Wendell Berry, Terry Tempest Williams, and Barry Lopez -- to examine the divide between faith and reason, and to seek a means for developing an environmental ethic that will help us confront two of our most imperiling crises: global environmental destruction and an impoverished spirituality. The book explores the ways in which science, spirit, and religion can guide the experience and understanding of our ongoing relationship with the natural world and examines how the integration of science and spirituality can equip us to make wiser choices in using and managing the natural environment. The book also provides compelling stories that offer a narrative understanding of the relations among science, spirit, and nature.

Grounded in the premise that neither science nor religion can by itself resolve the prevailing malaise of environmental and moral decline, contributors seek viable approaches to averting environmental catastrophe and, more positively, to achieving a more harmonious relationship with the natural world. By bridging the gap between the rational and the religious through the concern of each for understanding the human relation to creation, The Good in Nature and Humanity offers an important means for pursuing the quest for a more secure and meaningful world.

The Value of Life is an exploration of the actual and perceived importance of biological diversity for human beings and society. Stephen R. Kellert identifies ten basic values, which he describes as biologically based, inherent human tendencies that are greatly influenced and moderated by culture, learning, and experience. Drawing on 20 years of original research, he considers:

• the universal basis for how humans value nature
• differences in those values by gender, age, ethnicity, occupation, and geographic location
• how environment-related activities affect values
• variation in values relating to different species
• how vlaues vary across cultures
• policy and management implications
