Scientists once laughed at people who believed in invisible waves. Then the theory of electromagnetism demonstrated that we are immersed in an ocean of invisible waves. Scientist sneered at people who believed in invisible energies. Now scientists say that 95% of the universe is made of dark energy and dark matter that are wholly invisible. It won't be long until scientists have accepted the reality of ghosts.
Imagine a soul phone for contacting the dead, such as Thomas Edison believed possible. Would it be the most popular invention ever? Whom would you call? – famous figures from history, saints and prophets, or your dear departed ones? Or would you try to get through to God himself, and hope you didn’t get a crackly connection? Atheists always get “No Signal.”
Ghosts Are Real by Jack Tanner is a book that explains the mathematical domain of ghosts, spirits, and everything spiritual. It attempts to express how rationalism and idealism are the only keys to help us explore the ghost dimension - the dimensionless domain of mind, outside space-time. While Scientific Materialism and Empiricism can never provide us with anything valuable.
I would have loved if the book had dived deeper into Depth Psychology and the collective unconsciousness to explore ghosts and other paranormal activities.
