The contents of this book are thorough and concise. Geisler covers every imaginable worldview, describes the view, and proceeds to defend the Christian faith in light of the opposing view at hand. The book is philosophically rigorous, and laid out in a systematic fashion that helps the reader keep organized while tackling the many beliefs that stem from each of the views covered. Geisler covers rationalism, agnosticism, fideism, experientialism, evidentialism, pragmatism, combinationalism, deism, pantheism, panentheism, atheism, theism, etc. ~ T. B. Vick
