On December 20, 2005, a US district court in Dover, Pennsylvania, ruled in Kitzmiller et al v Dover Area School Board that teaching Intelligent Design in public school biology classes violates the Establishment Clause of the First Amendment to the Constitution of the United States. The judge explained that Intelligent Design is not science and ‘cannot uncouple itself from its creationist, and thus religious, antecedents’. This case was just the latest attempt by proponents of Intelligent Design or Creationism to undermine the teaching of evolution in high school biology classes. The emotionally charged controversy, which has been going on since the publication of Charles Darwin’s Origin of Species , shows no sign of letting up. This excellent collection, now fully updated, will inform readers about the history of the debate and bring philosophical clarity to the complex arguments on both sides. The editors, both of whom served as expert witnesses in two different court cases, start by chronicling the heated discussion that surrounded the publication of Darwin’s famous work. In the next part, they present articles that explicate modern evolutionary theory, including philosophical critiques by Karl Popper and others. The selections that follow discuss so-called Creation Science, focusing in particular on the 1981 McLean court case in Arkansas. In the final section, the philosophical issues surrounding the distinction between religion and science in the most recent Kitzmiller case are considered.
