Ragione, perfettibilità e seconda natura nel pensiero di J.G. Fichte

Abstract

This essay explores the concept of “second nature” in the philosophy of Johann Gottlieb Fichte, tracing its origins to Jean-Jacques Rousseau’s notion of perfectibility and its development through Immanuel Kant’s transcendental philosophy. The analysis highlights how, for Fichte, second nature concerns both the formation of the individual and the historical development of humanity, intertwining theoretical activity and practical life. Starting from early modern empiricism, especially John Locke and Étienne Bonnot de Condillac, the essay reconstructs the emergence of a historical conception of human nature. Rousseau identifies freedom and perfectibility as the distinctive features of humanity, while Kant interprets reason as the principle guiding the progressive realization of freedom. Fichte radicalizes this perspective by presenting transcendental philosophy as a “system of freedom,” in which second nature becomes the dynamic process through which reason shapes human practices, institutions, and forms of knowledge. The essay argues that second nature, in Fichte, is the historical and self-transformative sphere in which freedom progressively realizes itself.
