Simulacra and Simulation is most known for its discussion of images, signs, and how they relate to contemporaneity. Baudrillard claims that our current
society has replaced all reality and meaning with
symbols and
signs, and that human experience is of a simulation of reality.
Moreover, these simulacra are not merely mediations of reality, nor even deceptive mediations of reality; they are not based in a reality nor do they hide a reality, they simply hide that anything like reality is irrelevant to our current understanding of our lives. The simulacra that Baudrillard refers to are the significations and symbolism of
culture and
media that construct perceived reality, the acquired understanding by which our lives and shared existence is rendered legible; Baudrillard believed that society has become so saturated with these simulacra and our lives so saturated with the constructs of society that all meaning was being rendered meaningless by being infinitely mutable. Baudrillard called this phenomenon the "precession of simulacra".
