Swedenborg was a respected academic who methodically described the spiritual world, and left a strange collection of works which captivated the most eminent thinkers. Swedenborg derived inspiration from dreams and visions, and claimed to be able to visit heaven and hell at will. His works were widely read after his death and highly regarded by poets, writers and mystics such as Blake, Baudelaire, Strindberg, Balzac, Yeats, Jung, and William James.
