The Original Version of the Explanatory Filter 61 2. The Modified Version of the Explanatory Filter 62 viii PREFACE This research has been exciting, rewarding, and, at times, exhausting. I am very thankful for those who came alongside and helped me carry the load. Most of the time, they carried more than their fair share. My wife, Maria, just like our first years of life together, has been an unbelievable rock of encouragement throughout my higher education. As you read this for the first time, Maria, we made it! I realize that you always believed that we would make it, although I sometimes had my doubts. And now we can look forward to entering another exciting chapter of life, hand in hand. My parents, Levy and Clodean Belcher, have also gone the extra mile in their love and support. They've supported me unconditionally, despite often having trouble understanding the exact nature of my work and its significance. I thank God for such godly parents who have toiled all their lives to make the best life possible for my two brothers and myself. Much love and appreciation goes to my church family, Calvary Baptist Church, in Glasgow, Kentucky. They have greatly supported my many years of theological education. I only hope that I am now better able to give something back to them; that I can help in equipping the saints for God's glory. I will forever be indebted to the superlative faculty at Southern Baptist Theological Seminary—as both M.Div. and doctoral student. I will take with me lasting memories from Dr. James Parker. Not only does he instruct with a wealth of philosophical and theological insight, but Dr. Parker's down home Texas humor has also carried me through many long days with a smile. In addition to Dr. Parker, Dr. Chad Brand is another member of my research committee from whom I have learned much and ix can never begin to repay. Most of all, I sincerely thank my committee chairperson, Dr. Ted Cabal. None of this would be possible without his superb academic knowledge, leadership, and encouragement. Dr. Cabal has always challenged me with the perfect balance of tenacity and warmth. There is little doubt that I will return to him many times for his wisdom throughout my academic career. Special acknowledgment must also be made for other kind, gifted scholars who have guided and advised me during my research. They include Thomas Woodward, Steven Fuller, Bradley Monton, Casey Luskin, and, of course, the primary subject of this dissertation, William Dembski. I had the privilege of studying under Dr. Dembski during his brief time at Southern. It was during his seminar that I began to fathom the true significance of Intelligent Design, how fascinating it is, and the magnitude of Dr. Dembski's work in particular. This dissertation has required long hours of work and thought, and I have often become lost in the minutia of the content. However, it is fitting that in the final days of this research I am starting to remember what is truly important; all of this work is wasted if it of no use to the Church. I pray that what is presented in the pages ahead will aid many Christians in confronting "every high-minded thing that is raised up against the knowledge of God, taking every thought captive to the obedience of Christ" (2 Cor 10:5). May it somehow contribute to the advancement of his kingdom and to the glorification of his Name. Franklin Todd Belcher Glasgow, Kentucky December 2009 x CHAPTER 1 INTRODUCTION On December 20, 2005, Pennsylvania U.S. District Court Judge John Jones concluded that Intelligent Design (ID) was a cloaked form of creationist religion. The judge chastised the Dover, Pennsylvania, school board for their "breathtaking inanity" in adopting such an imprudent policy promoting ID, motivated by in "ill-informed" faction within the board.1 Therefore, according to his verdict for Kitzmiller v. Dover School District, the school board had violated the Establishment Clause of the First Amendment of the U.S. Constitution. The board was ordered to cease the reading of a brief written statement to ninth grade biology students. The statement had informed students of ID research as an alternative to the status quo Darwinian model of origins advocated in public schools. Also within the statement, students were informed that the pro-ID textbook, Of Pandas and People, was on file in the high school library. This book had been available to any student who might pursue supplemental investigation of theories that challenge Darwinian natural selection. Such information is now legally prohibited in Dover schools. A serious issue within academia's debate about origins is whether research that infers Intelligent Design should be considered as scientifically justifiable. Jones's verdict has contributed to growing skepticism of ID within scientific and public discourses; the trial's legal and scientific ramifications, along with its influence on what should be considered as "true science," cannot be overestimated. Nevertheless, another substantial 'judge Jones, "Memorandum Opinion," Kitzmiller et al v. Dover Area School District et al, 137-38 No. 04cv2688 (M. D. Pa. 2005). 2Percival Davis and Dean H. Kenyon, Of Pandas and People: The Central Questions of Biological Origins, 2nd ed., ed. Charles B. Thaxton (Dallas: Haughton, 1993). 1 2 question is whether the Kitzmiller conclusion about the illegitimacy of Intelligent Design is based on an accurate weighing of ID's actual research. If not, then is the ruling grounded in any amount of unwarranted caricature? More specifically, the present research works toward a determination of whether two of the trial's most influential witnesses, Barbara Forrest and Robert T.
