This book is a philosophical book on Mormonism by Mormon author and scientist Joseph Widtsoe. Widtsoe writes based on his conviction that there is no real difference between science and religion. He opines that, “The great, fundamental laws of the Universe are foundation stones in religion as well as in science. The principle that matter is indestructible belongs as much to theology as to geology. The theology which rests upon the few basic laws of nature is unshakable; and the great theology of the future will be such a one.”
