Abstract

According to recent scholarship, Kant’s "An Answer to the Question: What is Enlightenment?" and the introductory section to "The Conflict of the Faculties" are masterpieces of philosophical rhetoric. The philosophical significance of these texts lies in establishing the free public use of reason as a tool to discipline political power through pure practical reason, and the rhetorical mastery consists in presenting the free public use of reason as a means to satisfy the ruler’s pragmatic practical reason. Elaborating on this interpretation, I flesh out three further aspects of the writings in question. First, I examine the four types of arguments that Kant crafts in defence of the public use of reason and show how their pragmatic practical character is fully in keeping with the foundation of politics on pure practical ideas. Second, contrasting Kant’s notion of the public use of reason with the classical liberal conception of free speech, I argue that the distinctive character of Kant’s notion of the public use of reason consists in adding to the liberal demand for freedom from state censorship the requirement of the self-discipline of the participants in the public use of reason. Third, I contend that Kant’s notion of the public use of reason goes beyond a mere non-coercive discursive procedure and conclude that, to qualify as public in the distinctive Kantian sense, publicly presented positions must uphold theoretical and moral criteria informed by critical philosophy.
