All Camp objects, and persons, contain a large element of artifice. Nothing in nature can be campy.
Camp is a vision of the world in terms of style -- but a particular kind of style. It is the love of the exaggerated, the "off," of things-being-what-they-are-not.
Camp sees everything in quotation marks. It's not a lamp, but a "lamp"; not a woman, but a "woman." To perceive Camp in objects and persons is to understand Being-as-Playing-a-Role. It is the farthest extension, in sensibility, of the metaphor of life as theater.
