The purpose of this book is to provide intellectually rigorous people with a credible, modern religion - a religion based on the appreciation, care, and enhancement of life itself, while it embraces individual freedom as a precious part of the natural expression of life. Free of superstition, it seeks to be entirely in agreement with truth as we know it and regards that imposing value as more than beauty; it is sacred - and no truth more so than that on which we base our religion. The author begins in a manner similar to Descartes' often-referenced Method, with what we know for certain: we have life. Then he derives from that foundational reality all of his beliefs. He suggests that the basic tenet of such a religion would be Faith In Life - a trust in its greatness and logic - and that it contains within it the religious expression of Faith Through Life, that through the natural care and fulfillment of life we may not only preserve it and find considerate joy in it but also express our truest reverence to its ultimate source.
