Swedenborgianism the theosophy professed by a worldwide movement established as the New Jerusalem Church in London in 1788 by the followers of Emanuel Swedenborg (1688–1772), a Swedish natural philosopher, visionary, and biblical exegete. Author of geological and cosmological works, he fused the rationalist (Cartesian) and empiricist (Lockean) legacies into a natural philosophy (Principia Rerum Naturalium, 1734) that propounded the harmony of the mechanistic universe with biblical revelation. Inspired by Liebniz, Malebranche, Platonism, and Neoplatonism, he unfolded a doctrine of correspondence (A Hieroglyphic Key, 1741) to account for the relation between body and soul and between the natural and spiritual worlds, and applied it to biblical exegesis. What attracted the wide following of the ‘Spirit-Seer’ were his theosophic speculations in the line of Boehme and the mystical, prophetic tradition in which he excelled (Heavenly Arcana, 1749–56).
