One might find a science fiction reasons for reincarnation, perhaps using the term physical stream of particles such as “Mindo” of Orbit Ville Departure Bob Shaw’s. But what most people mean by reincarnation – the soul, which is to say qualitative aspects of a person, living life in a series of different institutions – is not considered as a scientific concept most people, and sits uneasily in a science fiction story.
Various methods have been tried to get some of the benefits of reincarnation with other devices plot. Serial bodies hero Gosseyn van Vogt is World of Null-A and immortal citizens in Jack Vance’s To Live Forever ; the matter to be sent a copy of Algis Budry is Rogue Moon – these are not exactly the reincarnation but they give the hero a chance to live again after he is killed
In Robert Heinlein’s . Beyond This Horizon scientific study reveals that reincarnation happens; it is reported that discovery, albeit unexplained one. In Edgar Rice Burroughs’ The Moon Maid the existence of reincarnation is accepted unquestioningly by the people on the moon, and the experience of land line narrator.
Obviously, the concept offers enormous benefits to any storyteller who wants plots full of vistas of time and opportunity. It might risk it becoming too open-ended, so if serial infinite life is available, the urgency of any life may seem diminished. To the extent that it can be a problem, it is covered in a variation on the theme of reincarnation provided by Ooranye Project. The giant planet residents take for granted that they will have more than one life, but they also know that the number of lives is limited, two or in rare cases, three. After the fate of their soul is unknown then.
In William Hope Hodgson The Night Country proposes to lovers separated by tragedy in a life can hold one, but Ooranye it is not mystical affinity to help this process along, and Indeed, in “The Open Secret” rare statistical coincidence that is doing the couple to meet again, leading to fear and joy.
