Institutions Without Angels: Kant, Madison, Popper, and the Ethics of Political Order in the Trump Era

Abstract This article develops a conception of institutional ethics for political orders under conditions of human fallibility. Its central claim is that the normative quality of a political institution should be assessed not primarily by the virtue of the persons who temporarily occupy it, but by the institution’s capacity to preserve freedom, responsibility, contestability, and corrigibility when officeholders are self-interested, mistaken, partisan, or willing to use lawful authority to its outer limits. The argument proceeds through four stages. First, Kant’s republicanism is read as an attempt to translate moral anthropology into institutional form: a constitution must be workable even for a “nation of devils,” while publicity supplies a moral test of public right. Second, Madison’s Federalist essays convert a related anthropology of non-angelic persons into constitutional mechanics—faction against faction, power against power, ambition against ambition. Third, Popper radicalizes this tradition by replacing the classical question “Who should rule?” with the institutional question of how rulers can be removed and harmful policies corrected without violence. Fourth, Popper’s own history of political philosophy is subjected to the fallibilist test he recommends for others. His treatments of Plato, Hegel, and Marx illuminate genuine dangers—epistemic monopoly, historical teleology, holism, and political prophecy—but they also compress distinct philosophical projects into a genealogy of the closed society. Plato preserves the problem of political knowledge; Hegel shows that freedom is socially embodied in Sittlichkeit; Marx reveals how material power and ideology can persist beneath formally liberal institutions. A reconstructed institutional ethics therefore must go beyond Popper’s negative institutionalism. It must evaluate not only constraints on rulers but also the distribution of agency, the traceability of responsibility, the material conditions of non-domination, the publicity of reasons, and the capacity of institutions to learn. The contemporary American presidency, including conflicts over executive power during Donald Trump’s second administration, is treated as a stress test rather than a partisan verdict. The broader lesson is that a durable constitutional order should not need a good ruler in order to remain a good order.Keywords: institutional ethics; Kant; Madison; Federalist Papers; Karl Popper; Plato; Hegel; Marx; open society; political fallibility; constitutionalism; responsibility; Donald Trump; institutional resilience
