Lost Legacy (1941) is a novella by science fiction writer Robert A. Heinlein. Originally published in the November, 1941 issue of Super Science Stories, it was collected in the book Assignment in Eternity (1953). The novella is an exploration of the possibilities that humans, with the proper training, have the potential to make use of a wide range of telepathic and telekinetic abilities. It is based on the presumption that most, if not all, humans have innate psychic abilities, but simply do not know it and therefore do not make use of them. This ignorance is encouraged by a mysterious and powerful cabal which benefits from keeping people unaware of their abilities.
