Emanuel Swedenborg (1688-1772) was a Swedish scientist, philosopher, and theologian known for his influential writings on spirituality and the nature of the afterlife. He initially gained recognition for his work in natural science, particularly in anatomy and engineering, but later shifted his focus to religious and mystical experiences. Swedenborg claimed to have visions of the spiritual world, which led him to develop a unique theological framework. His major works, such as Heaven and Hell, explore the relationship between God, humanity, and the afterlife. His ideas have influenced various religious movements, including New Church and Swedenborgianism.
