One of Brecht's most important contributions to theater is the idea of ​​"epic theater", which is a style of theater aimed at reminding audiences that these are demonstrations of human behavior and not real things, which is the opposite of what naturalism proposes. tries to show to the public. Naturalistic styles attempt to recreate real life and create deep characters that seem real in an attempt to gain audience empathy; Naturalism was used as entertainment and as an escape from the real world and public problems. Naturalistic theater wanted the audience not to think about deeper meaning and just feel emotions for the characters. Brecht hated this form of theater, he wanted the audience to think, challenge and question what they are.
