Although this is not the only topic Smith addresses in the book, I really appreciate the work he did on atheistic moral realism. Smith reviews all of the relevant literature--including that by J.L. Mackie, Robert Adams, and David O. Brink--and demonstrates the inherent plausibility of an atheistic moral realism. Smith also has occasion to defend a logical argument from evil. While I am skeptical of such arguments, Smith's book should serve as a reminder to theists who wish to proclaim the death of logical arguments from evil. If you've ever wondered how an objective morality could exist if God does not, and you've wanted a really thorough treatment of the issue, this book is for you. Although Smith's book can be difficult reading (especially for nonphilosophers), it is well worth the effort.
