In September 2007, four key proponents of New Atheism, popularly called the Four Horsemen, gathered for a two-hour filmed conversation in which they both explained their atheistic positions and addressed criticisms from theistic opponents. The discussion among Richard Dawkins (evolutionary biologist and ethologist), Christopher Hitchens (journalist, essayist, and political historian), Sam Harris (neuroscientist and moralist), and Daniel Dennett (philosopher) was viewed widely on YouTube. This book contains the entire transcript of that influential meeting as well as current reflections and comments by the group's three surviving members, as Hitchens died in 2011. Having the conversation available in book format is beneficial since current statements can be examined more closely and compared with arguments found in other writings. As the ideas of New Atheism in general and those of these four authors have received significant criticism over the years, revisiting the meeting allows these scholars to respond to criticism and contemporary readers to reflect anew on their ideas. VERDICT Spanning religion and philosophy, this work will appeal to readers of both, especially those interested in atheism and apologetics.—John Jaeger, Johnson Univ., Knoxville, TN
