Reprint of 1906 edition. Hardbound laminated. pp. 743. Emanuel Swedenborg (1688 - 1772) was a Swedish scientist, philosopher, Christian mystic, and theologian. Swedenborg had a prolific career as an inventor and scientist. Emanuel studied physics, mechanics, and philosophy, read and wrote poetry. He wrote in one of his letters a list of inventions he claims to have made, including a submarine and a flying machine.At the age of fifty-six he claimed he was appointed by the Lord to write a heavenly doctrine to reform Christianity. He claimed that the Lord had opened his eyes, so that from then on he could freely visit heaven and hell, and talk with angels, demons, and other spirits. For the remaining 28 years of his life, he wrote and published 18 theological works.In the two centuries since Swedenborg's death, various interpretations of his theology have been made, and he has also been scrutinized in biographies and psychological studies.
