The theory of proper names should not be conceived of in terms of representation; it refers instead to the class of "effects": effects that are not a mere dependence on causes, but the occupation of a domain, and the operation of a system of signs. This can be clearly seen in physics, where proper names designate such effects within fields of potentials: the Joule effect, the Seebeck effect, the Kelvin effect. History is like physics: a Joan of Are effect, a Heliogabalus effect—all the names of history, and not the name of the father.
