In this article, I look at recent developments in the field of the Philosophy of the relationship between morality, understood in a realist manner, and the primary object of religious belief in the monotheistic religions, God. Some contemporary solutions to the Euthyphro dilemma and versions of moral arguments for the existence of God are discussed.

Kant argues against the ontological argument for the existence of God but replaces it with a moral theism. This article analyses Kant’s moral proof with emphasis on the Critique of the Power of Judgement, and his historical and political writings. It argues that at the heart of this argument is the idea of progress. The concrete content of the moral law is the idea of a just world. Such a just world would be impossible without the idea of God, since (...) there would be no harmony between nature and freedom. It contrasts Kant’s concept of time and history with Heidegger’s. The difference between them is a reversal of modality. For Kant, actuality determines possibility. If I cannot imagine a just word as actual, then I would fall into moral despair. The idea of God grounds this actuality. For Heidegger, possibility is higher than actuality. Since history has no teleology, then no idea of God is required. (shrink)

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)

This essay tries to show that there exist several passages where Kierkegaard (and his pseudonyms) sketches an argument for the existence of God and immortality that is remarkably similar to Kant's so-called moral argument for the existence of God and immortality. In particular, Kierkegaard appears to follow Kant's moral argument both when it comes to the form and content of the argument as well as some of its terminology. The essay concludes that several passages in Kierkegaard overlap significantly with Kant's (...) moral argument, although Kierkegaard ultimately favors revealed faith over natural theology in general and Kant's moral faith in particular. Whereas Kant uses the moral argument to postulate the existence of God and immortality, Kierkegaard mainly uses it as a reductio ad absurdum of non-religious thinking. (shrink)

Kant’s ethics conceives of rational beings as autonomous–capable of legislating the moral law, and of motivating themselves to act out of respect for that law. Kant’s ethics also includes a notion of the highest good, the union of virtue with happiness proportional to, and consequent on, virtue. According to Kant, morality sets forth the highest good as an object of the totality of all things good as ends. Much about Kant’s conception of the highest good is controversial. This paper focuses (...) on the apparent conflict between Kant’s claim that we are autonomous, and passages in which he seems to suggest that we require belief in the possibility of the highest good to motivate moral action. I distinguish three distinct versions of these problematic claims that seem to be present in Kant’s texts: that the highest good serves as (1) a motivational supplement to respect for the moral law, (2) a fundamental spring of right action, and (3) a condition of the bindingness of moral requirements. I argue that the texts are better interpreted to yield alternatives to (2) and (3) that do not conflict with our autonomy. I also argue that, properly understood, (1) does not conflict with our autonomy. In arguing for the last claim, I explore Kant’s notion of radical evil and its implications for human agency and virtue. (shrink)
