Having imagined a machine-like world, scientists now haunt this machine uneasily. Their plight is paradoxical: They have realized their world only through intense mental effort, yet this effort finds no legitimate place in the world it so painstakingly comprehends. It seems “objectivity” only comes at a cost. Why, for example, is science unable to describe a smile? Why is the moral life of a physicist regarded as his or her own private affair?

This exclusion of human qualities from science has practical as well as theoretical consequences. If we systematically imagine a world in which human beings don’t exist, we will eventually create a world in which they can’t exist.

Few would question the fact that sense experience originally provided a firm basis for empirical natural science. Yet contemporary science has reduced the world to particles and forces that lie well beyond the reach of our human senses. The extraordinary—and alienating—fact is that human experience no longer has a place within our scientific worldview. The authors of this book have begun to unravel this paradox. They show that the concepts of modern physics such as mass, force, or velocity are deeply rooted in the experience of specific senses. Each of our senses is a gateway into a different aspect of the world. This insight throws a new light on the dilemmas of contemporary science, such as the wave-particle duality in quantum mechanics. By recognizing the essential role of sense perception in scientific knowledge, this highly readable book lays the foundations for a science that, while maintaining its rigorous methodology, can begin to incorporate the fullness of human experience into its domain.

“In this brilliant book, the authors build a fascinating bridge between science and the world of the senses, a bridge that holds great promise for overcoming the fragmentation and alienation that is so characteristic of our time.”
—Fritjof Capra, author of The Tao of Physics and The Web of Life

“… Likely to change many readers’ comprehension of science.”
—Small Press Review
