ABSTRACTThis essay is a translation of one of Salomon Maimon’s ethical writings, accompanied by a brief introduction. In it, Maimon proposes a correction of the Kantian moral principle of duty, as it is articulated both by Kant’s Groundwork for a Metaphysics of Morals and his Critique of Practical Reason. In particular, Maimon’s essay reveals the influence of Reinhold’s critique of Kant’s moral philosophy, especially regarding the role of incentives behind moral action. It reveals as well Maimon’s commitment to the primacy (...) of the theoretical over the practical, drawn from his reading of Maimonides and Spinoza. The essay, therefore, marks an important moment in the development of Maimon’s assimilation of Kantian philosophy, one often neglected in scholarship on his work. (shrink)
