“The Platonic Republic.” The Beginnings of Kant’s Juridico-Political Philosophy in the Critique of Pure Reason

The essay focuses Kant’s engagement with Plato at the beginning of the Transcendental Dialectic of the Critique of Pure Reason, which presents a crucial but often overlooked feature of Kant’s magnum opus. In particular, the essay examines Kant’s positive pronouncements on the “Platonic republic” (Platonische Republik) in Book One of the Transcendental Dialectic by placing them in the twofold context of the first Critique’s affirmative retake on Plato’s Forms (Ideen) and its original views on juridico-political matters. More specifically, the essay aims to show that Kant’s prime position in legal and political philosophy, as contained in the first edition of the Critique of Pure Reason (1781), involves a normative conception of civic life that places the societal exercise of individual freedom under universal laws. Section 1 explores the extent of affinity between Plato and Kant as arch-representatives of ancient and modern idealism. Section 2 traces the transition from Platonic dogmatism to Kantian criticism in the theory of ideas. Section 3 presents Kant’s appropriation of the idea of the “Platonic republic” for purposes of a specifically modern republican account of the rule of law under conditions of freedom
