ABSTRACT G. E. Morton tries to defend libertarianism against my claim that it relies on an implausible secularization of ideas of divine sovereignty. But it is not true, as he claims, that morality itself entails human sovereignty: witness the moral theories of divine‐command theorists and philosophical consequentialists. Nor is it true that sovereignty can be conceptually transferred from God to equal human individuals, since they would have no legitimate way to legislate over each other, short of a unanimous “general will.” (...) Nor, finally, does the idea of first possession rescue private property rights, since it is as applicable to animals and children as to adult human beings. (shrink)

Kant famously distinguishes between the categorical imperative (CI) and hypothetical imperatives (HIs), which are instrumental norms. On the standard reading, Kant subscribes to the of HIs, which takes HIs to be consistency requirements that bind agents in exactly the same way whether or not agents are subject to CI and whether or not they conform their choices to CI. I argue that this reading cannot be squared with Kant's account of an agent's disposition, in particular his claim that cognition of (...) CI is a necessary condition of willing a maxim. I further argue that Kant could not accept an account of HIs as consistency requirements. Finally, I outline Kant's conception of HIs as non-disjunctive requirements that arise when and only when agents will permissible ends. This account can help recapture Kant's conception of the unity of rational norms. (shrink)

Kant’s chapter “On the Typic of the Pure Practical Power of Judgement” is one of the most obscure passages of the Critique of Practical Reason and it has often been regarded as a mere appendix. However, it deals with a fundamental question, namely, how can the pure practical law be applied to particular cases. In this paper, I would like to make an original contribution towards a better understanding of this chapter by comparing it to the Schematism chapter on the (...) basis of their analogical relation and suggesting how the reference to a sensus communis could help in solving the aim of the Typic chapter.

On the currently dominant reading of the Groundwork, Kant’s derivation of ‘imperatives of duty’ exemplifies a decision procedure for the derivation of concrete duties in moral deliberation. However, Kant’s response to an often-misidentified criticism of the Groundwork by G. A. Tittel suggests that Kant was remarkably unconcerned with arguing for the practicality of the categorical imperative as a decision procedure. Instead, I argue that the main aim of Kant’s derivation of imperatives of duty was to show how his analysis of (...) the form of moral judgement is indeed presupposed in the four types of moral imperative that philosophers of his time recognized.

The Kantian strain of practical constructivism (through Rawls, Korsgaard, and others) has been so influential that it is tempting to identify the constructivist approach in practical domains with the Kantian development of the outlook. In this essay, I explore a different variety of practical constructivism, what I call “Aristotelian constructivism”. My aim is to establish conceptual space for this form of constructivism by indicating in what ways Aristotelian constructivism agrees with its Kantian counterparts and in what ways it differs. I (...) claim that it is, in one sense, more faithful to the constructivist enterprise than the Kantian varieties, in that its understanding of both the establishment of practical truth and the vindication of the theory itself is constructivist.

This critical survey of recent work on Kant's doctrine of the fact of reason and his doctrine of the practical postulates (of freedom, God, and immortality) assesses the implications of these doctrines for the debate about realism and antirealism in Kant's moral philosophy. Section 1 briefly surveys some salient considerations from the first Critique and Groundwork. In section 2, I argue that recent work on the role, content, "factual" nature, and epistemic status of the fact of reason does not support (...) an anti-realist interpretation of Kant's ethics. In section 3, I argue that recent work on the derivation and epistemic and ontological status of the practical postulates does not support an anti-realist interpretation of Kant's ethics. (shrink)

Kant takes autonomy to be recognizably valuable. In claiming that non-Kantian views of morality treat the morally good will as heteronomous, he intends to present an objection to these views. He expects proponents of these views to recognize that the implication of heteronomy is a serious objection; his task is not to convince them that heteronomy is bad, but to convince them that their views imply heteronomy.

This essay tackles head on the argument that sees an inherent paradox in the autonomy of the will as the ground for the authority of the fundamental practical norms. It points out that only on reductive understandings of the autonomy of the will can this idea be qualified as paradoxical, thereby yielding outcomes that either contradict their premises or present autonomy under a false guise. With that done, it will proceed to offer a conception of the autonomy of the will (...) which is not vulnerable to the paradox, and which may therefore be equipped to rest the fundamental practical norms on solid ground. Throughout this discussion, I will rely on constitutivism about practical reasons to specifically defend the twofold conclusion that (a) the paradox of autonomy can be avoided and that, relatedly, (b) if autonomy is properly conceptualised, it is fully equipped and well positioned to ground the authority of the fundamental practical norms.

Within Kantian ethics and Kant scholarship, it is widely assumed that autonomy consists in the self-legislation of the principle of morality. In this paper, we challenge this view on both textual and philosophical grounds. We argue that Kant never unequivocally claims that the Moral Law is self-legislated and that he is not philosophically committed to this claim by his overall conception of morality. Instead, the idea of autonomy concerns only substantive moral laws, such as the law that one ought not (...) to lie. We argue that autonomy, thus understood, does not have the paradoxical features widely associated with it. Rather, our account highlights a theoretical option that has been neglected in the current debate on whether Kant is best interpreted as a realist or a constructivist, namely that the Moral Law is an a priori principle of pure practical reason that neither requires nor admits of being grounded in anything else.
