People asked this question the entire time the Duke Parapsychology Laboratory was in existence. Except for those who already believe they have the answer, it’s kinda the question, isn’t it? You can argue that there are more pressing, immediate concerns, and I can’t argue with that, but when all is said and done, how can you not be curious?
The Rhine Research Center is taking on this question at a conference on May 5th and 6th. If you’re anyway near Durham, NC, you should go. (Excuse the cheesy photo, but I love a good cheesy ghost picture.)
