Systems thinking is an episteme. Characteristic of the natural sciences, systems thinking has heavily, if unevenly, influenced human sciences. It has informed the management of bureaucracy, corporations, populations, and national economy. Systemic governing has further collapsed into commerce with the consolidation of platform monopoly. In all these instances, legibility structures are designed, constructed, and employed to make a world readable (seeing it as a system) and manipulable (turning it into a project). This course examines these various institutional efforts and their consequences on the world they target.
