Walter Benjamin discusses how the aura of authenticity in a work of art is lost through mechanical reproduction. He argues that experiencing an original work of art in person allows one to perceive it differently than viewing a reproduction through a medium like film. Ernst Bloch and Georg Lukas debate whether expressionism is a revolutionary political movement or a form of fascism. Bloch disagrees with Lukas' dismissal of expressionism because Lukas fails to mention important expressionist paintings like The Scream, Starry Night, and View of Toledo that have lasting significance.
