If cosmology connotes an understanding of the structure of both a physical and a transcendent universe, contends Erich Robert Paul, it is virtually impossible to understand Mormonism outside the dimensions of cosmological thinking. This unique study examines how Mormonism shaped its cosmic vision, by using and developing cosmological ideas, and what this process says about science, religion, and Mormonism itself. Historically, Mormons have cultivated a particularly active and positive interest in those matters, as was first evidenced by Joseph Smith. Focusing on the creation of a unique Mormon cosmology and on how cosmological thinking expanded in the nineteenth century, Paul chronicles the emergence of a rational scientism within the church hierarchy during the early years of the twentieth century, spurred by Mormon scientist-authorities B.H.
