"The illusion of purpose is so powerful," writes Richard Dawkins, "that biologists themselves use the assumption of good design as a working tool." As an ardent proponent of Darwinian evolution, Dawkins imagines that all design in biology is merely an illusion. By contrast, this book shows that biologists use the assumption of design with success precisely because design in biology is not an illusion but real. In this book, William Dembski and Jonathan Wells present a compelling scientific case for the intelligent design of biological systems. Their laser-like analysis, clear explanations, and brilliant analogies will captivate every reader, whether trained scientist or curious layperson. Intelligent design (ID), as the study of patterns in nature best explained by intelligence, is already accepted in many special sciences. Archeology, forensics, and the Search for Extraterrestrial Intelligence (SETI) all belong to ID in this broad sense. These sciences, however, are uncontroversial because any intelligence there could be an "evolved" intelligence. In biology, by contrast, intelligent design is highly controversial because any intelligence there would be an "unevolved" intelligence - it would not be the product of purely material evolutionary processes. Thus, to convinced materialists like Richard Dawkins, who dogmatically accept Darwinian orthodoxy, this book comes as a shot across the bow. Scientists who support the intelligent design of biological systems are routinely held up to ridicule, stripped of their status, denied tenure, and driven from their posts. Why? They do not agree that the universe, life, and the human mind are the accidental outworking of purely material forces. And why don't they agree? Because the evidence of science shows otherwise. This book presents that evidence clearly and cogently. Written for the general reader, it will quickly enter the national conversation. In The Design of Life, Dembski and Wells make the most powerful and comprehensive case to date for the intelligent design of life. This is the book that the promoters of unintelligent evolution do NOT want you to read.
