A leading scientist examines the battle between evolution and Intelligent Design in America

At the dawn of the twenty- first century, the debate over Darwin's theory of evolution is nearly as contentious as it was in the notorious Scopes trial a century ago. Today, however, people who believe that evolution is "only a theory" have put their hopes in a concept known as Intelligent Design.

In Only a Theory, Kenneth Miller dissects the claims of the ID movement in the same incisive style that marked his testimony as an expert witness in Pennsylvania's landmark 2005 Dover evolution trial.

Unlike other books on the subject, Only a Theory's critique of ID goes far beyond the scientific claims of the movement. To Miller, America's "soul"�its place as the world's leading scientific nation�is at risk because of this struggle. As he explains, the tactics of this new assault on science mimic earlier efforts of the academic left to remake science as a relativistic, culturally determined enterprise, rather than a rational search for truth about the natural world. Such marginalization, he argues, would effectively destroy American science.

Despite this analysis, Miller refuses to play the role of pessimist. He sees this as a teachable opportunity, a moment at which public understanding and support for science can be redeemed, and offers nothing less than a prescription for how America can save its scientific soul.
