This document summarizes Santiago Castro-Gómez's analysis of the "invention of the other" through modern power structures. It discusses how the modern state project aimed to rationally control and direct human life through mechanisms like the social sciences and the formation of nation-states. This entailed "inventing" citizens by constructing identities through disciplinary mechanisms like constitutions, etiquette manuals, and grammar books. These excluded those who did not fit the modern subject profile, effectively "inventing" the other. While illuminating power/knowledge dynamics, the analysis does not fully connect these local processes to the global capitalist system, leaving an opening for a broader geopolitical perspective.
