By fusing the scientific and spiritual knowledge of humankind under the banner of experience, this book seeks God by searching through the modern understanding of the world. In terms of mathematics, quantum mechanics, cosmology, life/genetics and information technology a bedrock of unchanging truth is not found. The book then moves on to the major propositions for and against the existence of God, namely world religious practice and evolution theory. A bedrock of proof is only uncovered through an experimental journey and reinforced by using case studies grouped into three catagories: normal, boundary and transcendental. The case studies are intended to further the understanding of the spiritual/transcendental reality in a similar way case law is used in the English legal system. The reader is urged to explore their own experiences. Beyond All Reasonable Doubt does not prove or disprove God's existence, it merely raises more questions and insists that we look within ourselves for the answers.
