This book is a standard apologetics textbook in many seminaries and schools in the U.S.. This is so for many good and obvious reasons. First, Geisler is well known and considered by many to be one of the greatest apologists of this century. Second, the contents of this book are so thorough and concise that there is actually no other book that has been published before or after this one that could be considered a viable rival. This is not to say that there are no other great apologetic texts out there. But there are very few that match this one. 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. He has a chapter that is devoted to the formulation of adequate tests for truth, and then a section that details Christian apologetics from History to the deity and authority of Christ. This is why this book has been a standard text for classes all over the country in the area apologetics. I cannot recommend this book enough! ~ T. B. Vick at Amazon.com
