There’s a big word that you can add to your vocabulary: Simulacrum. It is a hard word to wrap your head around, but one you are not too likely forget. Indeed, you should not forget it!
Collins defines as: “1) a an image; likeness, 2) a vague representation; semblance; 3) a mere pretense; sham.”
Cambridge Dictionary says: “something that looks like or represents something else”.
Purdue University put it this way: “Something that replaces reality with its representation.”
Jean Baudrillard wrote about this in an 1981 paper called "The Precession of Simulacra" where he digs deeper, making a distinction between a simulation and simulacrum.
Whereas representation attempts to absorb simulation by interpreting it as a false representation, simulation envelops the whole edifice of representation itself as a simulacrum. Such would be the successive phases of the image:
it is the reflection of a profound reality;
it masks and denatures a profound reality;
it masks the absence of a profound reality;
it has no relation to any reality whatsoever;
it is its own pure simulacrum.
So, the switch for reality is anti-reality: “The simulacrum is never what hides the truth – it is truth that hides the fact that there is none.”
