Kant’s accounts of the Highest Good and the moral argument for God and immortality are central features of his philosophy. But both involve lingering puzzles. In this entry, we first explore what the Highest Good is for Kant and the role it plays in a complete account of ethical life. We then focus on whether the Highest Good involves individuals only, or whether it also connects with Kant’s doctrines about the moral progress of the species. In conclusion, we look into (...) three ways of articulating the moral argument for God and immorality that take our commitment to the Highest Good as their point of departure. (shrink)

There are two main meanings in Kant’s concept of moral certainty (moralische Gewissheit, certitudo moralis): first, it applies to the kind of certainty embodied in rational faith in the existence of God and a future life; second, it applies to the conscientiousness (Gewissenhaftigkeit) required of an agent in the practice of moral judgement. Despite the growing attention to Kant’s theory of conscience and his concept of conscientiousness, this article is the first to discuss ‘moral certainty’ as the aim of ‘conscientiousness’ (...) and to highlight the relevance of both notions in regard to moral education and the purposes of Kant’s ethical doctrines of method.

In this paper, we analyse conceptions of induction and certainty in Wolff and Crusius, highlighting their competing conceptions of physics. We discuss (i) the perspective of Wolff, who assigned induction an important role in physics, but argued that physics should be an axiomatic science containing certain statements, and (ii) the perspective of Crusius, who adopted parts of the ideal of axiomatic physics but criticized the scope of Wolff’s ideal of certain science. Against interpretations that take Wolff’s proofs in physics to (...) be based on empirical statements that are probable, we show how inductively established statements, coupled with assumptions concerning the uniformity of nature, can be certain according to Wolff. We examine Crusius’ little known work on physics and show that he attacked Wolff, arguing that many statements of physics are probable. We provide a discussion of the reception of methodological rules similar to Newton’s Regulae Philosophandi, discussing different interpretations of such rules. We conclude by briefly hinting at how the debate between Wolff and Crusius provides historical context for understanding Kant’s philosophy of natural science. (shrink)

It is well-known that Kant defends a conception of God and the final end of our moral striving, called the highest good. In this article, I outline Kant's argument for why we ought to have faith in God and hope for the highest good, and argue that the Kantian argument can be extended in such a way as to show the unity of the theological virtues. This feature of the Kantian account can then have ramifications in further questions regarding the (...) relationship of faith and moral action. (shrink)

The aim of this paper is to show the unity and consistency of Kant’s reflections throughout all three sections of the Canon of Pure Reason. More specifically, I argue that Section 3, which is devoted to the issue of Fürwahrhalten, or taking-to-be-true, is crucial to achieving the methodological goal of the Canon, which is to justify the legitimacy of the speculative assumptions of pure reason. After examining the historical roots of Kant’s notion of a transcendental doctrine of method, I focus (...) on the methodological role that the practical element plays in the first two sections of the Canon. I then show how the limitations of Kant’s argument necessitate the introduction of a third crucial section, which serves both an analytic and an orientative function. (shrink)

In his new book, Rossi emphasizes the prominent role of enlightened religion in the political project of establishing perpetual peace. My paper discusses Rossi’s stance on the question as to whether Kant, in his later years, moved to an immanentist conception of the highest good. Kant’s own position in this regard can arguably be better described as comprehensive, according to which an immanent and a transcendent conception of the highest good are upheld as realizable side by side. Rossi’s account looks (...) perfectly consistent with such a view. One of the reasons for such a comprehensive reading is that “immanent” and “secular” do not coincide in Kant in the first place. Seen in this comprehensive way, and while a version of the highest good ought to be realized immanently, we cannot be certain that this will indeed happen. If it does indeed happen, the immortality postulate, which Kant never abandoned, renders it rational to believe that the immanent version of the highest good is merely a step towards its transcendent realization. Affinities of Rossi’s approach to the suggestion that Kant subscribes to a political theology based on what has been called “Molinism minimally defined” will also be explored. (shrink)

This article aims to highlight the extent to which Kant’s account of belief draws on the views of his contemporaries. Situating the non-evidentialist features of Crusius’s account of belief within his broader account, I argue that they include antecedents to both Kant’s distinction between pragmatic and moral belief and his conception of a postulate of pure practical reason. While moving us closer to Kant’s arguments for the first postulate, however, both Crusius’s and Meier’s arguments for the immortality of the soul (...) fail to anticipate the most important aspect of their Kantian counterparts. Developing the non-evidentialist features of Basedow’s account of belief, I distinguish it from its Pascalian and Jamesian relatives and argue that it is the clearest antecedent to Kant’s arguments for the first and second postulates. Finally, I consider the development of Kant’s account of belief after the first Critique in light of the foregoing, and discuss the broader implications of my analysis. (shrink)
