Ghosts

A ghost is usually defined as the apparition of a deceased person, frequently similar in appearance to that person, and encountered in places he or she frequented, or in association with the person's former belongings. The word "ghost" may also refer to the spirit or soul of a deceased person, or to any spirit or demon. Ghosts are often associated with haunting, which is, according to the Parapsychological Association, "the more or less regular occurrence of paranormal phenomena associated with a particular locality (especially a building) and usually attributed to the activities of a discarnate entity; the phenomena may include apparitions, poltergeist disturbances, cold drafts, sounds of steps and voices, and various odors.

Ghosts are controversial phenomena. According to a poll conducted in 2005 by the Gallup Organization, about 32% of Americans believe in the existence of ghosts. The term ghost has been replaced by apparition in parapsychology, because the word ghost is deemed insufficiently precise.

Origin of Ghosts

The belief in ghosts as souls of the departed is closely tied to the ancient concept of animism, which attributed souls to everything in nature, including human beings, animals, plants, rocks, etc.

Although the human soul was sometimes symbolically or literally depicted in ancient cultures as a bird or other animal, it was widely held that the soul was an exact reproduction of the body in every feature, even down to clothing the person wore. This is depicted in artwork from various ancient cultures, including such works as the Egyptian Book of the Dead, which shows deceased people in the afterlife appearing much as they did before death, including the style of dress.

Another widespread belief concerning ghosts is that they were composed of a misty, airy, or subtle material. Anthropologists speculate that this may also stem from early beliefs that ghosts were the person within the person, most noticeable in ancient cultures as a person's breath, which upon exhaling in colder climates appears visibly as a white mist. This belief may have also fostered the metaphorical meaning of "breath" in certain languages, such as the Latin spiritus and the Greek pneuma, which by analogy became extended to mean the soul. In the Bible, God is depicted as animating Adam with a breath.

Although the evidence for ghosts is largely anecdotal, the belief in ghosts throughout history has remained widespread and persistent.

In many historical accounts, ghosts were thought to be deceased persons looking for vengeance, or imprisoned on earth for bad things they did during life. Most cultures have ghost stories in their mythologies. Many stories from the Middle Ages and the Romantic era rely on the macabre and the fantastic, and ghosts are a major theme in literature from those eras.

Ghost stories date back to ancient times, and can be found in many different cultures.

One of the earliest known ghost "sightings" in the west took place in Athens, Greece. Pliny the Younger (c. 63 - 113 AD) described it in a letter to Licinius Sura: Athenodoros Cananites (c. 74 BC – 7 AD), a Stoic philosopher, decided to rent a large, Athenian house, to investigate widespread rumors that it was haunted. Athenodoros staked out at the house that night, and, sure enough, a dishevelled, aged spectre, bound at feet and hands with rattling chains, eventually "appeared". The spirit then beckoned for Athenodoros to follow him; Athenodoros complied, but the ghost soon vanished. The philosopher marked the spot where the old man had disappeared, and, on the next day, advised the magistrates to dig there. The man's shackled bones were reportedly uncovered three years later. After a proper burial, the hauntings ceased.

Many Eastern religious traditions also subscribe to the concept of ghosts. The Hindu Garuda Purana has detailed information about ghosts.

The ancient texts of the Hebrew Torah and the Bible mention many ghostly events. For instance, in the Second Book of Samuel, a disguised King Saul has the Witch of Endor summon the spirit of Samuel, while in the Gospel of Matthew, the Twelve Apostles at first believe Jesus to be a ghost when they see him walking on water. In addition, the Holy Ghost is a common way to describe the Holy Spirit as described in various ancient texts of the Bible.

Critics of "eyewitness ghost sightings" suggest that limitations of human perception and ordinary physical explanations can account for such sightings; for example, air pressure changes in a home causing doors to slam, or lights from a passing car reflected through a window at night. Pareidolia, an innate tendency to recognize patterns in random perceptions, can cause people to believe they have seen ghosts. Reports of ghosts "seen out of the corner of the eye" may be accounted for by the sensitivity of human peripheral vision

The traditional perception of ghosts wearing clothing is considered illogical, given the supposed spiritual nature of ghosts, suggesting that the basis of what a ghost is said to look like and consist of is quite dependent on preconceptions made by society. Skeptics also say that, to date, there is no credible scientific evidence that any location is inhabited by spirits of the dead
