The simulacrum has long been of interest to philosophers. In his Sophist, Plato speaks of two kinds of image-making. The first is a faithful reproduction, attempted to copy precisely the original. The second is distorted intentionally in order to make the copy appear correct to viewers. He gives an example of Greek statuary, which was crafted larger on top than on bottom so that viewers from the ground would see it correctly. If they could view it in scale, they would realize it was malformed. This example from visual arts serves as a metaphor for philosophical arts and the tendency of some philosophers to distort truth in such a way that it appeared accurate unless viewed from the proper angle. Nietzsche addresses the concept of simulacrum (but does not use the term) in The Twilight of the Idols, suggesting that most philosophers, by ignoring the reliable input of their senses and resorting to the constructs of language and reason, arrive at a distorted copy of reality.
Postmodernist French social theorist Jean Baudrillard argues that a simulacrum is not a copy of the real, but becomes truth in its own right: the hyperreal. Where Plato saw two steps of reproduction — faithful and intentionally distorted (simulacrum) — Baudrillard sees four: (1) basic reflection of reality, (2) perversion of reality; (3) pretence of reality (where there is no model); and (4) simulacrum, which “bears no relation to any reality whatsoever”. In Baudrillard’s concept, like Nietzsche’s, simulacra are perceived as negative, but another modern philosopher who addressed the topic, Gilles Deleuze, takes a different view, seeing simulacra as the avenue by which accepted ideals or “privileged position” could be “challenged and overturned”. Deleuze defines simulacra as “those systems in which different relates to different by means of difference itself. What is essential is that we find in these systems no prior identity, no internal resemblance”.
