Abstract

The notion that "nature" comes equipped with its own set of categories, enabling us to divide up everything that exists without overlap or leftovers, has considerable explanatory and prescriptive power. I examine two apparently unrelated arenas in which this notion is at work; namely, in the alleged discovery and subsequent physical "improvement" of the headwaters of the Mississippi River, and in the surgical alteration of intersex infants. In both cases, reconstruction is undertaken as a means of eliminating an ambiguity regarded as "unnatural" —an "error" in nature that culture must correct. Elilminating ambiguity, in turn, enables accessibility. Fixing a person or a river firmly in a category allows us to have various kinds of access to them. For a river, the access is in part physical; it means being able to walk up to its headwaters without wearing hip waders. For a person, the access is both intellectual and social; only once I know what sex a person, is do I know how to treat them, and only then do I know whether they are an "appropriate" object of my erotic attention.
