Abstract

“Natural logic” was proposed by Lewis Henry Morgan as the engine of cultural evolution, concluding that the “course and manner” of cultural development “was predetermined, as well as restricted within narrow limits of divergence, by the natural logic of the human mind.” This essay argues that Morgan’s conception of natural logic aids the project of settler colonialism. Rather than being a false account of human agency, however, it is a conception of natural logic that is produced through the systematic narrowing of possibilities for agency, human, and otherwise. This narrowed logic is thus only a part of a differently conceived logic of agency that is also general and normative. The discussion proceeds in four sections: first, a presentation of Morgan’s conception of natural logic and its origins; second, an analysis of four colonizing implications of Morgan’s view; third, examples of further developments of natural logic in the twentieth and twenty-first centuries in the work structuralist and post-structuralist theorists; and, last, a brief introduction of a decolonial logic that provides a broader alternative conception of the structure of agency, human, and otherwise, and that avoids the oppressive effects of the reductionism of the natural logic received from Morgan and his successors.
