In his early text, The Limits of State Action, Wilhelm von Humboldt raises the Kantian question of the permissibility and legitimate extent of political and juridical coercion, as his contribution to a debate amongst Kantians launched by the publication in 1785 of Kant’s Groundwork of the Metaphysics of Morals. In arguing for a minimal state, concerned exclusively with internal and external security of its members but not at all with their felicity, Humboldt inflects Kantian political thought in the direction of (...) a liberal laissez-faire state, in marked contrast to the strong interventionism that his fellow-Kantian Fichte derived from similar Kantian grounds. The article argues that the underlying conception of the individual retained by Humboldt has markedly Leibnizian traits, namely the notion of freedom as the spontaneous unfolding of a highly personal, monadic developmental trajectory toward perfection, which ought not to be impeded or homogenized by unnecessary state intervention. Humboldt thus represents not only a ‘rightist’ libertarian reading of Kant, but a particular appropriation of significant Leibnizian themes. His combination of these sources is compared with that of other contemporary theorists like Hufeland and Fichte. (shrink)
