Second sight is a form of extrasensory perception, the supposed power to perceive things that are not present to the senses, whereby a person perceives information, in the form of a vision, about future events before they happen (precognition), or about things or events at remote locations (remote viewing).
Second sight may have originally been so called because normal vision was regarded as coming first, while supernormal vision is a secondary thing, confined to certain individuals. "an da shealladh" or "the two sights," meaning "the sight of the seer", is the way Gaels refer to "second sight", the involuntary ability of seeing the future or distant events. There are many Gaelic words for the various aspects of second sight, but "an da shealladh" is the one mostly recognized by non-Gaelic speakers, even though, strictly speaking, it does not really mean second sight, rather 'two sights'. It originated in the Scottish Highlands. [Citation needed].
An early example of symbolical second sight is found in the Odyssey, where Theoclymenus sees a shroud of mist about the bodies of the doomed Suitors, and drops of blood distilling from the walls of the hall of Odysseus. The Pythia at Delphi saw the blood on the walls during the Persian War; and, in the Argonautica of Apollonius Rhodius, blood and fire appear to Circe in her chamber on the night before the arrival of the fratricidal Jason and Medea. Similar examples of symbolical visions occur in the Icelandic sagas, especially in Njala, before the burning of Njal and his family. In the Highlands, and in Wales, the chief symbols beheld are the shroud, and the corpse candle or other spectral illumination.
Ranulf Higdons Polychronicon (14th century) describes Scottish second sight, adding "that strangers setten their feet upon the feet of the men of that londe for to see such syghtes as the men of that londe doon".
Second sight and extrasensory perception
These phenomena may be classed under clairvoyance, precognition, and telepathy. There is no scientific evidence that second sight exists. Reports of second sight are known only from anecdotal evidence given after the fact. A famous book with documented alleged cases of second sight was the two-volume Phantasms of the Living (London: Trübner, 1886) written by the psychical researchers Frederic William Henry Myers, Edmund Gurney and Frank Podmore. The book claimed that visions of apparitions were telepathic hallucinations.
The two-volume Phantasms of the Living was criticized by scholars for the lack of written testimony and the time elapsed between the occurrence and the report of it being made. Some of the reports were analyzed by the German hallucination researcher Edmund Parish (1861–1916) who concluded they were evidence for a dream state of consciousness, not the paranormal. Charles Sanders Peirce wrote a long criticism of the book arguing that no scientific conclusion could be reached from anecdotes and stories of unanalyzed phenomena. Alexander Taylor Innes attacked the book due to the stories lacking evidential substantiation in nearly every case. According to Innes the alleged sightings of apparitions were unreliable as they rested upon the memory of the witnesses and no contemporary documents had been produced, even in cases where such documents were alleged to exist.
In the early 20th century Joaquin María Argamasilla known as the "Spaniard with X-ray Eyes" claimed to be able to read handwriting or numbers on dice through closed metal boxes. Argamasilla managed to fool Gustav Geley and Charles Richet into believing he had genuine psychic powers. In 1924 he was exposed by Harry Houdini as a fraud. Argamasilla peeked through his simple blindfold and lifted up the edge of the box so he could look inside it without others noticing.
Science writer Martin Gardner has written that the ignorance of blindfold deception methods has been widespread in investigations into objects at remote locations from persons who claim to possess second sight. Gardner documented various conjuring techniques psychics such as Rosa Kuleshova, Lina Anderson and Nina Kulagina have used to peek from their blindfolds to deceive investigators into believing they used second sight.

"Phantasms of the Living was criticized by a number of scholars when it appeared, one ground for the attack being the lack of written testimony regarding the apparitions composed shortly after they had been seen. In many instances several years had elapsed between the occurrence and a report of it being made to the investigators from the SPR."
