In the absence of supernatural phenomena, much of what has permeated human history and worldview would be radically transformed. For instance, if beings from a parallel world—who influence people through telepathy, telekinesis, levitation, and other phenomena—were not involved, not only would the explanations for various parapsychological effects vanish, but many symbols that served as the basis for understanding good and evil would also disappear. This would mean that culture, religious worldview, and value systems would undergo profound changes, since many questions about the meaning of life, suffering, and the fate of the world have been linked to the manifestation of the supernatural.
