This document discusses the concept of catharsis as presented by Aristotle. Catharsis refers to the purification or purging of emotions, where tragedy raises emotions of pity and fear in both the audience and tragic hero, and then purges them. There are several theories of catharsis, including the purification theory where catharsis means cleansing or changing emotions quantitatively or qualitatively, the clarification theory where catharsis means an ideal state is achieved through tragedy, and psychological interpretations where tragedy gives an outlet for emotions of pity and fear, resulting in emotional relief. Examples of catharsis include scattering ashes of a loved one or ceremonies after life stages to encourage strong emotions to be released.
