Famed Psychologist Dr. James H. Hyslop wrote in 1918 of how a skeptic cannot remain skeptical about spirits once the evidence is examined…
“I regard the existence of discarnate spirits as scientifically proved and I no longer refer to the sceptic as having any right to speak on the subject. Any man who does not accept the existence of discarnate spirits and the proof of it, is either ignorant or a moral coward. I give him short shrift, and do not propose any longer to argue with him on the supposition that he knows anything about the subject.”
Professor James H. Hyslop was of of the first psychologists who linked psychology and psychic phenomenon. He was also an early member of the Society for Psychical research. You can learn more about his scientific studies regarding existence of life after death by picking up a copy of Life After Death, Problems of the Future Life and its Nature (1918), a classic that is always being reprinted.
