Moral realism faces two worries: How can we have knowledge of moral norms if they are independent of us, and why should we care about them if they are independent of rational activities they govern? Kantian constitutivism tackles both worries simultaneously by claiming that practical norms are constitutive principles of practical reason. In particular, on Stephen Engstrom’s account, willing involves making a practical judgment. To will well, and thus to have practical knowledge (i.e., knowledge of what is good), the content (...) of one’s will needs to conform to the formal presuppositions of practical knowledge. Practical norms are thus constitutive of practical knowledge. However, I will argue that the universality principles from which Engstrom derives the formal presuppositions of practical knowledge are reflectively and psychologically unavailable. As a result, they cannot help Kantian constitutivism provide an answer to moral realism's worries. (shrink)

I will argue that Avicenna’s and Aquinas’s faith-based virtue ethics are crucially different from Aristotle’s virtue ethics, in that their ethics hinges on the theological notion of heaven, which is constitutively independent of the ethical life of the agent. As a result, their faith-based virtue ethics is objectionable. Moreover, I will also argue that the notion of heaven that Avicenna and Aquinas deploy in their moral philosophy is problematic; for it can rationally permit believers to commit morally horrendous actions. Finally, (...) I will present a Kantian notion of heaven which is immune to the aforementioned moral objection. The Kantian notion of heaven, nevertheless, cannot ground any view of ethics as it is constitutively dependent on the ethical life of the agent. (shrink)

There are two kinds of view in the literature concerning the relevance of intention to permissibility. While subjectivism assumes that an agent acts permissibly if he or she believes that the conduct is necessary for a moral purpose, for objectivism the de facto presence of an objective reason to justify one’s deeds is what matters. Recently, Scanlon and Hanser defend a moderate version of objectivism and subjectivism, respectively. Although I have a degree of sympathy toward both views, I will argue (...) that the truth lies somewhere in between. The view that I suggest in this paper hopefully occupies a space between subjectivism and objectivism and can accommodate the intuitions that neither of those views cannot account for. (shrink)

Some religious requirements seem genuinely arbitrary in the sense that there seem to be no sufficient explanation of why those requirements with those contents should pertain. This paper aims to understand exactly what it might mean for a religious requirement to be genuinely arbitrary and to discern whether and how a religious practitioner could ever be rational in obeying such a requirement. We lay out four accounts of what such arbitrariness could consist in, and show how each account provides a (...) different sort of baseline for understanding how obedience to arbitrary requirements could, in principle, be rational.
