Una defensa de los deberes para con uno mismo en Kant y algunas observaciones respecto de su replanteamiento en Fichte

One of the most frequently criticized elements of Kant´s Metaphysics of Morals is the possibility of ethical duties to oneself. In this article I consider the most common arguments against these duties (from the standpoint of Utilitarianism) and I show how they can be refuted using Kant´s argumentation himself. Afterwards, I point out how Fichte, in his Doctrine of Morals, accepts the duties to oneself, but relocates them within the system of duties. Finally, I suggest that the fichtean reinterpretation emerges from a confusion over the role of the first-person moral agent in the Kantian ideal of the Kingdom of ends.
