The variety of reification (to treat as a real thing) that results from supposing that whatever can be named or conceived abstractly must actually exist. When (in Through the Looking Glass) his Messenger declares "I'm sure nobody walks much faster than I do," the White King hypostasizes "Nobody" by responding that "He can't do that, or else he'd have been here first." Such philosophers as Plato, Hegel, and Heidegger are sometimes accused of similar flights of ontological whimsy.
