The document discusses the differing views of Plato and Aristotle on the purpose of art. For Plato, art should be limited and serve only to teach moral lessons and promote ethics, otherwise it could be harmful. Aristotle believed that art should provide pleasure for the audience and include elements like language, character, and plot that could elicit catharsis in the viewer, rather than strictly teach morality. Both philosophers had a major influence on Western art but there remains a debate on whether art should primarily teach or simply be enjoyed.
