Billy Egnehall analyzes the film Rashomon and the differing views of Errol Morris and Roger Ebert on truth and perception. Ebert believes truth is relative and perception is subjective, while Morris sees truth as absolute and perception as objective. Egnehall supports Ebert's view, citing theories of common sense, certainty, and beliefs to justify that perspective can differ between individuals. He argues common sense allows people to make sense of situations differently, and certainty is based on individual perception and understanding through the senses and language. Ultimately, what people decide to believe depends on their own judgment, so truth is relative between accounts rather than absolute.
