Emanuel Swedenborg (1688–1772) was a Swedish theologian, philosopher, scientist, and mystic who’s best known for his elaborate spiritual visions and the theological works he produced in the second half of his life. He’s a fascinating figure because he transitioned from being a highly respected scientist and inventor to becoming one of the most prolific mystics of the 18th century.
Brilliant polymath: He worked in fields like astronomy, physics, chemistry, anatomy, and geology.
Invented early versions of submarines and flying machines.
Wrote The Principia (1734), where he tried to explain the creation of the universe using mechanical philosophy — sort of a forerunner to modern physics ideas.
Around 1744, Swedenborg began having mystical dreams and visions.
Claimed he could communicate directly with angels, spirits, and even Jesus.
Said he traveled spiritually to Heaven and Hell and spoke with people who had died.
His most famous theological writings include:
Heaven and Hell (1758)
Divine Love and Wisdom
Arcana Coelestia (a massive commentary on the Bible)
He believed in correspondences — the idea that everything in the natural world reflects a spiritual counterpart.
Taught that true Christianity had become corrupted and needed spiritual renewal.
Denied traditional doctrines like the Trinity (as usually understood), salvation by faith alone, and eternal damnation.
His ideas inspired the Swedenborgian Church (aka the New Church).
Had a big impact on Romantic poets (e.g., Blake, Coleridge), transcendentalists (like Emerson), and even Carl Jung was influenced by his model of spiritual realms.
