La legge della libertà in Sartre, una lettura kantiana

This essay explores Sartre’s existentialism as a radicalization of Kant’s theory of freedom. It critiques common interpretations of Sartre as an apologist for free will, emphasizing instead his focus on freedom in situation and ethical responsibility. In particular, the article highlights how Sartre overcomes the Kantian dualism between the phenomenal and noumenal dimensions, the antinomy between reason and sensibility, and offers a more radical vision of social justice. Simultaneously, it suggests that Kant can provide Sartre with an explicit normative basis lacking in his thought. The analysis explores how both philosophers aim to avoid alienation, albeit with different approaches, and how Sartre’s engaged freedom can be grounded in a practical principle of non-contradiction of freedom. The essay concludes by proposing an 'existentialist imperative' that promotes one’s own and others’ freedom, underscoring how Sartrean ethics can offer a relevant contribution to the contemporary debate in moral philosophy.
