I looked briefly to see if Swedenborg appeared in combination with Anderson and found a very interesting site
about Swedenborg's life. It's well written.
For the last 29 years of his life, S felt he was privy to communication with God, who showed him how there was a spiritual realm that co-existed with the earthly realm. His mission was, he said, to explain that realm to those who couldn't see it.
If it weren't for his Puritanical--whoops, an anachronism!--interpretations, I'd find myself fascinated and even swayed.
My own judgement is that he may have had a bi-polar or other mental disorder. Just a guess.
What's compelling about his writing is that he apparently thought for himself (although his own biases seem to have crept into his work), and said occasionally very interesting things:
"All who come into heaven have a place allotted them there, and thence eternal joy, according to their idea of God."
