In her new book The ESP Enigma: The Scientific Case for Psychic Phenomena, former Harvard professor Diane Hennacy Powell combines philosophy, physics, and empirical data to examine supernatural traits like telepathy (the ability to access someone else's consciousness), psychokinesis (the ability to use one's consciousness to affect external objects), clairvoyance (the ability to broaden one's consciousness to remote time and space) and precognition (the ability to see into the future).
