Presented in this book is the case against creationist pseudo-science. One theme emphasized throughout the book, written for those with or without science backgrounds, is that although the creationist campaign is an assault on evolutionary theory, it constitutes an attack on all sciences. Chapter 1 provides a brief introduction to evolutionary theory. Chapters 2-4 constitute a defense of evolutionary theory against creationist objections. Global objections are addressed and discussed in chapter 2. Chapter 3 considers more specific creationist complaints about the methods of evolutionary biology. These are based on misunderstandings of scientific methodology or evolutionary theory, or both. Chapter 4 considers the "scientific facts" that are supposed to refute evolution. Chapter 5 offers a critical evaluation of creation "science," examining creationist doctrine and whether the doctrine can be used to solve scientific problems. In this context, the significance of recent debates within evolutionary theory and creationist proposals for revising the geologic time table are discussed. Chapter 6 focuses on educational questions, including what genuine intellectual tolerance is required of individuals and tactics creationists use in exploiting tolerance. Chapter 7 examines the charge that evolutionary theory is intolerable because it is inimical to religion and morality. (JN)
