This chapter explores the view that, far from being an objective biological category, the category of the human is an ideological construction that is basic to ways that human societies exercise power. In short, the category of the human is a social construction. The chapter points out that when a group of people essentializes itself—sees itself as fundamentally and ineradicably distinct from all other people—the concept of the human becomes indistinguishable from the concept of “our kind.” In ethnically homogenous societies, this means members of the society are human, and everyone else is not. In heterogenous societies where there is “racial” or ethnic diversity—that is, most modern societies—the situation is more complex. In such societies, the concept of the human is an ideological structure. It is a concept that is used to legitimate and regulate relations of domination. If, as is often the case, the dominant group essentializes itself, that becomes the paradigm of the human and all others are either lesser humans or, at the extreme, subhumans. This view of what it means to be human has some important implications for the struggle against dehumanization.
