"Simulacra and Simulation" is a philosophical work by Jean Baudrillard that explores the relationship between reality, symbols, and society. Baudrillard argues that in contemporary culture, representations of reality (simulacra) have replaced the actual reality, leading to a world where images and signs dominate our understanding of existence. The text discusses four stages of the image: it reflects reality, it masks reality, it masks the absence of reality, and it bears no relation to any reality whatsoever. This concept highlights how modern society often engages with a hyperreality, where the distinction between the real and the simulated becomes increasingly blurred.
