On very rare occasions a book is written that has the potential to shake up our understanding of reality and change the world. It is no exaggeration to suggest that "Ultimate Truth", by Oxford philosopher Steven Colborne, is such a book. With confidence and wisdom Colborne explains the errors of traditional theological thinking before proceeding to describe the true nature of God in a way that no religion has yet managed to do. Simplicity and clarity are hard to find in philosophy, but Colborne has a gift for expressing his worldview in a way that will surely speak to the heart of each and every reader. It may take some time for the full impact of the ideas contained in this book to be realised, but "Ultimate Truth" is destined to establish Steven Colborne as the most important philosopher of our time.
