The author considers this to be the first book to be devoted to retrocognition, or direct, noninferential knowledge of the past, or as Mackenzie phrases it, "the experiencing of the past in the present" (p. xii), but I believe that honor, for books in English anyway, goes to Gracia Fay Ellwood, whose book Psychic Visits to the Past: An Exploration of Retrocognition (New American Library, 1971) was the first, Mackenzie has written many sound studies of various types of spontaneous parapsychological experiences, including apparitions, hauntings, precognition, ghosts, and some on different types of cases in one. He not only reviews the literature on these experiences but makes first-hand investigations if possible, and then analyzes a possible paranormal factor in some depth. In Part One he devotes 4 chapters to as many cases, some, such as the Adventure at Versailles are well known. In a final chapter, he reviews the evidence in these cases. In Part Two, Puzzling and Controversial Cases, he presents examples of five different types of retrocognition: spectral houses, buildings glimpsed in passing, sounds from the sea, figures in a landscape, and a dangerous walk on the cliffs. In the last chapter he searches for keys to the puzzle of retrocognition. Of special importance is a composite of features that occur in many cases of retrocognition (pp. 130-131). He closes with a call for more cases. |
