These four short works by Swedish scientist and spiritual teacher Emanuel Swedenborg (1688-1772) cover different areas of his early theology. New Jerusalem is a summation of the ideas laid out in Swedenborg's first major theological work, Secrets of Heaven, making it an excellent reference for those who want an overview of the work; Last Judgment presents the startling claim that the Last Judgment has already happened in the spiritual world and that it heralded the dawn of a new spiritual age for humanity; White Horse is a commentary on Chapter 19 of the book of Revelation, focusing on the symbolism of the white horse described in that chapter; and Other Planets describes Swedenborg's encounters with spirits from other inhabited worlds.
