‘Psi’, the Greek letter ψ, is the modern term for psychic phenomena. The existence of psi – and the related idea that consciousness is independent of the physical body (and so may survive bodily death) – are disputed, as they seem to violate well-established natural laws. However, researchers are convinced they have evidence for these things, posing a challenge to materialist science. The Psi Encyclopedia presents their reasoning in over 700 signed articles by 86 authors, many of them senior academics. It also provides links to books, articles and videos that are free to view.

ESP & Psychokinesis

The term extra-sensory perception (ESP), introduced in the 1930s, comprises telepathy, clairvoyance and precognition, acknowledging that these categories may considerably overlap. Psychokinesis is the direct influence on matter by mind alone, without physical action. All have been successfully tested in the laboratory and studied in real life situations.

Gifted People

Most people may only experience a psychic event once or twice in their lives, but for a few it’s a natural ability, which some develop as a professional career. Two types feature in the Psi Encyclopedia: those who have demonstrated telepathy, clairvoyance, precognition or psychokinesis in some way, and those who believe themselves to be in communication with the deceased.

Mind & Body

This category contains articles that treat consciousness in relation to the body. Major topics covered include healing and psychotherapy; dreams and dreaming; and out-of-body experiences, end-of-life experiences, and near-death experiences, all of which suggest that consciousness may have an existence independent of the physical body.

Survival of Death

Life continued in a spiritual or purely mental form after bodily death is a staple of religious beliefs worldwide, and likely is as old as humanity. The question of evidence for it has been central to the Society for Psychical Research since its founding in 1882. This category includes articles on mediumship as well as general topics related to the survival question. Other survival-related topics appear under other category headings.

Reincarnation

Reincarnation beliefs are widespread in the world and in recent decades researchers have found what they believe is evidence of them through the study of people (mainly children) who claim to have lived before. This category includes case studies and overviews of phenomena that appear regularly in the cases. Some articles deal with past life regression as well.

Angela Grubbs, a lawyer living in Atlanta, experienced intense dreams and visions of a young woman whose life and circumstances she was able to verify.

Dreams and Past-Life Memory

Apparent past-life memories may surface in the dreams of both children and adults, but rarely are they detailed enough to be verified.

Haunting

Location-based hauntings have been relatively little studied by parapsychologists, but the frequent incidence of apparitional episodes (the appearance of a deceased family member) attracted the attention of early researchers. Much interest has also centred on so-called ‘poltergeist’ episodes, of powerful domestic disturbances now often attributed to involuntary psychokinetic effects by living agents.

Organizations

The oldest organizations devoted to parapsychology were member organizations like the Society for Psychical Research, established in London in 1882. Since JB Rhine founded the Parapsychology Laboratory at Duke University in 1930, there have been university-based units as well. This category comprises both historical and contemporary bodies concerned with research and education in parapsychology.

This category includes biographies of leading sceptics as well as general articles discussing their allegations.
