This document summarizes Walter Benjamin's essay "The Work of Art in the Age of Mechanical Reproduction". In 3 sentences: Benjamin argues that technological advances in reproduction have transformed art by diminishing the authentic "aura" of original works and by allowing for mass consumption. He believes this has shifted art's purpose from ritualistic "cult value" to public "exhibition value". Benjamin also analyzes how these changes impact film as an emerging art form and its relationship to theater, and explores film's potential as a tool for psychoanalysis or political messaging.
