Defining corruption has proven to be such a difficult challenge that many contemporary analysts pass over the question as quickly as possible. But while definitions are too important to be dismissed as an analytical concern, a single one-dimensional definition that will satisfy all observers will never be found. Rather than proposing yet another definition, this article explores five dimensions of the concept: corruption as social decline, as deviant behavior, as a logic of exchange, as a system of measurable perceptions, and corruption as "shadow politics". All help us view corruption within actual social settings; all lend further detail to the sorts of contrasts among concepts and usages that Arnold Heidenheimer explored in his work. In the end one of the most important aspects of the issue is that of trust, which not only helps us understand how corruption functions in actual cases but also underscores the reasons why we must continue to fight it.
