Kant’s moral proof of the postulate of immortality in the Critique of Practical Reason is often dismissed as a failed argument that trades on illicit conceptual shifts. I argue that Kant’s argument is more interesting and less problematic than is usually thought. I first examine its role in the second Critique’s Dialectic. I then point out that the standard interpretation, according to which the argument presupposes God’s intuitive grasp of the moral equivalence between the disposition to pursue holiness and its (...) attainment, faces a number of philosophical and textual problems. I offer an alternative reading that avoids these problems. In particular, I stress the importance of Kant’s mathematized conception of the relationship between infinite progress towards an ideal goal and its attainment and argue that appealing to this conception allows Kant to meet a well-known criticism that his proof illegitimately substitutes the endless progress towards holiness for holiness itself.

Kant’s Formula of Universal Law (FUL) is generally believed to require you to act only on the basis of maxims that you can will without contradiction to become universal laws. In “Contradiction and Kant’s Formula of Universal Law” (2017), I have proposed to read the FUL instead as requiring that, for any maxim on which you act, you can will two things simultaneously, without volitional self-contradiction: (1) willing the maxim as your own action principle and (2) willing that it become (...) a universal law. In the present essay, I reply to comments by Mark Timmons, Michael Walschots, Paola Romero, and Stefano Lo Re. In response to their comments concerning the application of the FUL, I expand the interpretive framework of the Volitional Self-Contradiction Interpretation. I argue that Kant also constructs the diagnostic volitional self-contradiction as a contradiction between (1) willing a tested maxim to become a universal law and (2) willing what humans, qua finite rational beings, necessarily will, namely the means to their actual and possible future ends. I also clarify how the two ways in which Kant specifies the test are related. Furthermore, I clarify the relation between the Volitional Self-Contradiction interpretation and other interpretations of the FUL, in particular the ‘Practical Contradiction’ and ‘Logical Contradiction’ interpretations, as well as its difference from the Golden Rule. I also address the objection that the volitional self-contradiction is superfluous, clarify the relation between the Formula of Universal Law and the Formula of the Law of Nature, and explain why the will of an immoral agent does not contain a volitional self-contradiction of the type at issue.

Kant’s account of practical justification for belief has attracted much attention in the literature, especially in recent years. In this context, scholars have generally emphasized the originality of Kant’s thought about belief (Glaube), and Kant indeed offers a definition of belief that is very different from views that were prevalent in eighteenth-century Germany. In this article, however, I argue that it is very likely that Christian August Crusius exerted influence on Kant’s definition of belief and his account of practical justification. (...) In turn, acknowledging this influence has relevant consequences for how we understand the phenomenology of Kantian belief. (shrink)

The article has the aim to show that Kant’s “standard” conception of the highest good does not represent his last word about the problem. Kant moves from a conception of the highest good close connected with the metaphysical tradition and with the aim of a new, moral justification of traditional metahysical concepts such as God and immortality of the soul. This view does find many difficulties and oscillations in the Critiques, looking for different formulations of a moral “proof” for the (...) metaphysical concepts, grounded upon the need of justice and of a rational solution to the question of theodicy. The failure of this project is apparent with the essay on theodicy. In the last decade of Kant’s intellectual activity, the expression “highest good” occurs few times and the concept looses its systematic relevance, as shown by the last works up to the Opus postumum.

Kant maintains that the only thing that is good in itself, and therefore good without limitation or qualification, is a good will. This is an objectionable claim in support of a controversial position. The problem is not just that the good will is not the only thing that is good in itself, which indeed it is not, but more importantly, that the good will is not so much a thing that is good in itself as it is the good kind (...) of a thing that is otherwise neither good nor bad in itself. The goodness of a good will is no more intrinsic than the goodness of a good act, good outcome, good attitude, good character, or good person. Nor is it even any more so than something as commonplace as a good laugh or a good cup of coffee. A good will, whatever else it may be, is a will that is good, much like how a good act is an act that is good, a good outcome is an outcome that is good, and so on with the other examples, not one of which is good for any reason other than the goodness predicated of the corresponding subject. This paper thus challenges Kant’s position on ontological grounds. It questions the validity of claiming intrinsic goodness for a complex construct whose goodness is, in fact, extrinsic to its substance. The objection is not that the good will might not turn out to be good after all, which is impossible by definition, designation, or stipulation, but that its goodness is axiomatic and derivative rather than intrinsic or fundamental.

The paper develops a Kantian view of the highest good and the relation between virtue and happiness. Several Kantian theses are defended, among them the thesis that the highest good is realized only if every virtuous individual is happy, the view that virtue is neither necessary nor sufficient for happiness, and the proposition that virtue is both necessary and sufficient for the worthiness of being happy. The author argues that the highest good ought to be realized and that it ought (...) to be that everyone who is virtuous is happy. To prove these claims, the author will use techniques developed by modern deontic logicians. According to Kant, we do not have an immediate duty to promote our own happiness, the aim of morality being not personal satisfaction but rather virtue and the good will. The important question is not “How do I become happy?” but “How do I become good?”. The arguments in this paper support this view. (shrink)
