Simulacra and Simulation

Simulacra and Simulation (French: Simulacres et Simulation) is a 1981 philosophical treatise by the sociologist Jean Baudrillard, in which the author seeks to examine the relationships between reality, symbols, and society, in particular the significations and symbolism of culture and media involved in constructing an understanding of shared existence. Simulacra are copies that depict things that either had no original, or that no longer have an original. Simulation is the imitation of the operation of a real-world process or system over time.
