Of the four narrators in Rashomon, one of them did not lie. This event was commonly known as the Rashomon Paragon. It was described by the French philosopher, Plato, in his dialogue, Rashomon. There are four people in the story, including a narrator, a doctor, a policeman, and a victim. They each hear different versions of the same incident. However, there were some contradictions in each version, so it was impossible to determine the true appearance of the incident. Since every narrator is involved in the story, at least one of them will lie. But if all narrators lie, then it contradicts the story itself because the events must be believable. Therefore, in this case, only the narrator who did not lie could confirm the authenticity of the event.
