This is one of the text books that we are using in our "Worldview Analysis" Class. I must say at first the book seemed intimidating. But the book is an excellent tool! And a must have on every Christians shelf! Sire does a fantastic job of looking through major worldviews such as Naturalism, Theism, Islamic Theism, Deism, Nihilism, and many others. He breaks each view down into 8 subheadings (1. What is ultimate reality 2. What is the external reality 3.What is a human being (soul, and body or just body?) 4. What happens at death 5. How can we know anything 6. How do we know what is right and wrong 7. What is the purpose of History? 8. What is the overall purpose or goal in mind for this worldview? Through each of these questions he shows ultimately where the worldview ends up. This book I truly believe will enhance your growth in the area of Apologetics!!
