The claims of evolution and, more recently, the proponents of artificial intelligence have brought into question what it means to be human. Denying the existence of the soul apart from the body, many contemporary scientists are devout materialists‹putting the traditional Aristotelian and Thomistic conception of the human being far out of fashion. However, Ric Machuga argues convincingly that our nature "is an essential unity of both the material and the immaterial," that we not only have a soul but that we are a soul. The body is a necessary‹but not sufficient‹condition for human existence. In Defense of the Soul is an accessible and timely treatment of a timeless topic: what it means to be human. Not only will it attract readers interested in artificial intelligence, evolution, and the intelligent design debate, it¹s ideal for introductory college and seminary courses in philosophy. It includes an appendix that specifically assesses intelligent design, as well as a thick bibliography that provides an excellent guide to other sources on the topic.
