Noneism, also known as modal Meinongianism[1][2] (named after Alexius Meinong), is both a philosophical and theological theory. In a philosophical and metaphysical context, the theory suggests that some things do not exist. That definition was first conceptualized by Richard Sylvan in 1980 and then later expanded on by Graham Priest in 2005.[3][4] In a theological context, noneism is the practice of spirituality without an affiliation to organized religion.
