I attempt first to disentangle three aspects of Kant’s distinction between perfect and imperfect duty. There is the central distinction between principles of duty contrary to that which is contradictory in conception/consistent in conception but contradictory in will. There is also a distinction between essential and non-essential duties: those which cannot, or occasionally can, be passed over consistent with the requirements of morality. Finally, there is a distinction between duties that exhibit a scalar aspect – degrees of goodness or virtue (...) – and duties that do not. My aim is to show how these distinct considerations can be reconciled as aspects of a single distinction, and I conclude that the remarkable complexity of Kant’s perfect/imperfect distinction is actually a strength, rather than a weakness.

I argue that by considering Kant’s engagement with previous theorists of natural right, we can gain a clearer understanding of how he transformed the discipline from its foundations. To do this, I focus my analysis on Kant’s (critical) reception of two models of natural right with which he was very familiar: one from Alexander Baumgarten’s Elements of First Practical Philosophy [Initia philosophiae practicae primae], the other from Gottfried Achenwall’s Natural Law [Ius naturae]. The Initia served as a basis for Kant’s (...) lectures on moral philosophy for over three decades and may thus be considered as having played an important role in shaping his practical philosophy as a whole. Achenwall’s Ius naturae was the textbook that Kant employed in his lectures on natural right for over two decades. I argue that Kant distances himself from previous models of natural right in three main regards: the identification of moral laws with laws of nature, the normative connection between the principles of right and a natural end, and the place of God as the author of moral laws. I then briefly discuss what Kant retains of Baumgarten’s and Achenwall’s models of natural right. Kant’s Metaphysics of Morals preserves the view that a rational doctrine of right belongs to a broader systematic doctrine that comprehends the entire system of duties. I address the question of the division of the Sittenlehre into two branches and claim that, whereas Kant did not consider Baumgarten’s answer to the problem of distinguishing juridical from ethical principles to be satisfactory, he found a key piece of his own resolution in Achenwall’s Ius naturae, namely the definition of right as a power to coerce.

Kant’s practical philosophy, Rawls’s theory of justice and contemporary human rights thinking are landmarks in liberal discussions of justice. Each forms part of a powerful tradition of political thought, and although their substantive accounts of justice diverge at many points, they also overlap in substantial ways. This article focuses not on their substantive claims about justice, or about other ethical standards, but on their differing views of thequestionsto be addressed, on their proposedjustificationsfor standards of justice, and on a limited range (...) of questions aboutinterpretingandinstitutionalizingthose standards.

Natural law contains much social thought that predates sociology and related disciplines, and can be seen as part of the prehistory of the human sciences. Key concerns of natural law thinkers include the achievement of social life and society, and the individual’s place therein. However, there is an enduring tendency within sociology to dismiss the ahistoricism and universalism of natural law, and therefore to reject natural law thought in its entirety. This article proposes an approach that rescues the sociological relevance (...) of natural law. It draws on the respective methods of Chris Thornhill and Gary Wickham, who each seek to recover the importance of natural law for sociology. Thornhill treats natural law as a valid sociological object by focusing on its functions within society rather than engaging with its ahistorical concepts. His focus on the external functions of natural law, however, leads to a neglect of the internal conceptualisations of the social world in natural law thought. This in turn leads to a misinterpretation of Hobbes and voluntarist natural law. Wickham, on the other hand, explores in detail Hobbesian conceptions of society and the individual that Wickham argues can be utilised within contemporary sociology. This article revises Thornhill’s methodological framework in order to secure a space for the recovery of natural law as social thought. This approach allows for the recognition of natural law as an important piece of the epistemological background against which contemporary understandings of the human and society emerged. (shrink)

In his later writings, Kant distinguishes between autonomy and self-mastery or self-command. My article explains the relation between these two ideas, both of which are integral to his understanding of moral agency and the pursuit of virtue. I point to problems with other interpretations of this relation and offer an alternative. On my view, self-command is a condition or state achieved by those agents who become proficient at solving problems presented by the passions. Such agents are able to stick to (...) the results of self-legislation over time and thereby achieve a form of temporally extended freedom. (shrink)

En el presente artículo, el autor analiza el concepto de leyes prácticas propuesto por Kant en la Crítica de la razón práctica, poniendo énfasis en los antecendentes que este concepto tiene en la escuela del derecho natural moderno y en el giro que este concepto representa, ya que en él se hace patente el paso desde una ética de la obligación hacia una ética de la autonomía. Se analizan además las propiedades esenciales del concepto de leyes prácticas y los problemas (...) filosóficos que surgen a partir de él y se sitúa dicho concepto en el contexto general de la ética kantiana y de la filosofía moral. In this article the author analyzes the concept of "practical law" as developed by Kant in his Critique of Practical Reason. The author notes the roots of this concept in the modern school of natural law and states that this concept represents a shift from an ethic of obligation to an ethic of autonomy. In addition, the author analyzes the essential features of the "practical law" concept; the philosophical problems that arise from it, and the place of this concept in the landscape of Kantian ethics and moral philosophy.
