The idea of autonomy, presented as Kant’s main achievement in the Groundwork and the second Critique, is hardly present in the ethics of the “Doctrine of Virtue”. Against Pauline Kleingeld’s recent interpretation, I argue that this does not amount to a disappearance of the Principle of Autonomy, but to an important development of the notion of autonomy. I first show that Kant still advocated the Principle of Autonomy in the 1790s along with the thought of lawgiving through one’s maxims. I (...) then argue that the role of autonomy in Kant’s later ethics has a different focus than in the previous works, which requires to connect autonomy with autocracy. Conversely, in the “Doctrine of Virtue”, autocracy, which Kant had employed before as an independent notion, is construed as a new layer of autonomy. What Kant there calls subjective autonomy is thereby considered as reason’s self-government in the maxims of each rational agent. -/- . (shrink)

Immanuel Kant (1724–1804) argued that moral requirements are based on a standard of rationality he dubbed the “Categorical Imperative” (CI). Immorality thus involves a violation of the CI and is thereby irrational. Other philosophers, such as Locke and Hobbes, had also argued that moral requirements are based on standards of rationality. However, these standards were either desirebased instrumental principles of rationality or based on sui generis rational intuitions. Kant agreed with many of his predecessors that an analysis of practical reason (...) will reveal only the requirement that rational agents must conform to instrumental principles. Yet he argued that conformity to the CI (a non-instrumental principle) and hence to moral requirements themselves, can nevertheless be shown to be essential to rational agency. This argument was based on his striking doctrine that a rational will must be regarded as autonomous, or free in the sense of being the author of the law that binds it. The fundamental principle of morality — the CI — is none other than the law of an autonomous will. Thus, at the heart of Kant's moral philosophy is a conception of reason whose reach in practical affairs goes well beyond that of a Humean ‘slave’ to the passions. Moreover, it is the presence of this self-governing reason in each person that Kant thought offered decisive grounds for viewing each as possessed of equal worth and deserving of equal respect.

In the Doctrine of Right Kant holds that the classical Ulpian command honeste vive is a juridical duty that has the particular feature of being internal. In this paper I explore the reasons why Kant denies that the duty to be an honorable human being comprises an ethical obligation and conceives it as a juridical duty to oneself. I will argue that, despite the conceptual problems that the systematical incorporation of this type of duty into the doctrine of morals might (...) entail, these reasons are coherent. The fulfillment of the duty honeste vive involves a coercion to the self but at the same time does not necessarily imply the adoption of a moral end. (shrink)

Uno de los elementos más criticados de la Metafísica de las costumbres es el de la posibilidad de deberes éticos con uno mismo. En este artículo reviso las críticas más usuales y muestro cómo pueden refutarse desde la propia argumentación kantiana. Después señalo cómo Fichte, en su Doctrina de las costumbres, acepta los deberes con uno mismo, pero los reubica en el sistema de los deberes. Finalmente comento que la relectura fichteana parte de una confusión respecto del papel del agente (...) moral en primera persona en el ideal kantiano del reino de los fines. (shrink)
