Divine Love and Wisdom by Emanuel Swedenborg.

Early in his life, Emanuel Swedenborg established a lasting reputation as a scientist in many scientific fields, including physics, astronomy, mathematics, engineering, and human anatomy. His research in several of these fields culminated in important publications that showed him well in advance of his time. His work in anatomy, for example, anticipated some of the later theories of physiology, including those involving the functions of the ductless glands.
