A discovery is a revelation of something which was previously unknown. An unknown place, element or fact, the broad definition of a discovery can cover many different situations. According to Aristotle, Discovery is an important part of a story plot. Discovery is one of the two properties which Aristotle attributes to forming a complex plot (236). "A Discovery is, as the very word implies, a change from ignorance to knowledge, and thus to either love or hate, in the personages marked for good or evil fortune," (237). A discovery can lead to the revelation of truth and goodness, or the exact opposite.
