Note: This chapter deals with human psychic facilities and human ghosts, but not demons.
As we learned in chapter 4, parapsychology attempts to scientifically investigate the following four major psychic aptitudes:
Clairvoyance: the ability to “see” at a distance without using the eyes.
Telepathy: the ability to send and receive information directly from brain to brain
Precognition: the ability to know the future
Psychokinesis: The ability to move physical objects with the mind alone
In parapsychology, these attributes, called paranormal phenomena or psi for short, are all part of the human psyche and do not necessarily involve ghosts or any spiritual entities at all.
