Think of why this sense that someone is with you would have had survival value in human evolution. Think too of how the someone who seems to accompany survivors of extreme ordeals might also accompany those who die and never tell their stories. Don't assume the "third man," if you ever see him, will save you. He may comfort you as you give up the fight to stay alive. On the up side, you will probably feel quite wonderful.
"Imagine the impact on our lives if we could learn to access this feeling at will," [says John Geiger, author of "The Third Man Factor."] "There could be no loneliness with so constant a companion. There could be no stress in life that we would ever again have to confront alone."Response #1: Religious people have learned to access that feeling at will. Response #2: It's not a "learned" "feeling," it really is God/Jesus/your guardian angel. Response #3: We need the feeling of loneliness to get us out of the house and connecting with other people, without which there will be no survival of the species, so therefore — if the scientific evolutionary theory is the true one — then the "third man" phenomenon must remain a sometime thing. Response #4: If #3 is correct, then how can religion have survived? Response #5: Therefore, there is a God. Response #6: No, therefore religions require rules that ban or limit masturbation and push believers into marriage and procreation.
