A common theological critique of intelligent design (ID) centers on the problem of dysteleology. This problem states that because there are clear examples of suboptimal design in biology, life is probably not the product of an engineer-like designer. If it were, then one could argue that the designer is less than fully competent. ID critic Francisco Ayala expresses this critique in the following question: ""If functional design manifests an Intelligent Designer, why should not deficiencies indicate that the Designer is less than omniscient, or less than omnipotent?"" This book provides a philosophical analysis of two approaches to answering this question, one offered by Ayala and the other offered by William Dembski, a leading ID theorist. ""Claims the world displays intelligent design have long, distinguished support in the history of ideas. Though not new to the dialogue, recent robust challenges include the contention that apparent poor biological designs underscore doubts about the Designer's existence or capabilities. Berhow's judicious treatment of the current debate, therefore, provides welcome help for those navigating this terrain. I highly recommend Dysteleology!"" --Ted Cabal, Professor of Philosophy and Christian Apologetics, The Southern Baptist Theological Seminary, Louisville, KY ""Many scientists have expressed doubts about intelligent design. In this carefully argued work, Michael Berhow convincingly demonstrates that flawed (suboptimal) design in nature does nothing to undermine the main arguments supporting intelligent design. This book is a valuable contribution to the literature. Highly recommended."" --Stewart Kelly, Professor of Philosophy, Minot State University Michael Berhow is Lecturer of Philosophy at South Dakota State University.
