In the Dialectic of the first Critique, Kant claims that a highest being is the transcendental ideal of speculative reason. However, the Canon of the Doctrine of Method presents the highest good as an ideal of both the speculative and the practical use of reason. In this paper, I argue (1) that the highest good is the ideal of the unity of reason – unlike the ideal in the Dialectic – insofar as (2) the highest good serves both the speculative (...) and the practical employment of reason. Accordingly, I also argue that (3) these two employments are complementary, not alternative. Kant’s argument for the ideal of the highest good in the Canon shows that the unity of reason combines the two lawful employments of reason. In order to be reason’s highest ideal, this ideal cannot just mirror the demands of speculative reason – it must also involve the other fundamental employment of reason, i. e., the practical. This highest standpoint cannot be merely speculative but must be moral as well: not just a highest ideal, but also a good (the highest good). (shrink)

In this paper, I want to focus not on the problems that I believe may threaten Kant’s account of the highest good, but instead on those that I believe threaten the majority of the interpretive reconstructions attempted by commentators and thus prevent the emergence of a consensus in the near future. My goal is to set forth exactly four problems to which I believe any successful interpretation or reconstruction of Kant’s account of the highest good will have to provide substantive (...) solutions and, in doing so, either break new theoretical ground or at least provide a more comprehensive methodology for sorting through the texts.

The philosophy of Diogenes pays special attention to knowledge. Diogenes bases his thought on the well-known thesis of Parmenides which identifies einai and noein, combining it with the nous of Anaxagoras. According to Diogenes, the intellect (noesis) is embodied in the formal features of things and therefore is powerful, like the nous of Anaxagoras. The aim of the following pages is to show, in confrontation with Laks, that noesis does not homogenize the cosmos, but rather it diversifies it.

Immanuel Kant (1724–1804) argued that moral requirements are based on a standard of rationality he dubbed the “Categorical Imperative” (CI). Immorality thus involves a violation of the CI and is thereby irrational. Other philosophers, such as Locke and Hobbes, had also argued that moral requirements are based on standards of rationality. However, these standards were either desirebased instrumental principles of rationality or based on sui generis rational intuitions. Kant agreed with many of his predecessors that an analysis of practical reason (...) will reveal only the requirement that rational agents must conform to instrumental principles. Yet he argued that conformity to the CI (a non-instrumental principle) and hence to moral requirements themselves, can nevertheless be shown to be essential to rational agency. This argument was based on his striking doctrine that a rational will must be regarded as autonomous, or free in the sense of being the author of the law that binds it. The fundamental principle of morality — the CI — is none other than the law of an autonomous will. Thus, at the heart of Kant's moral philosophy is a conception of reason whose reach in practical affairs goes well beyond that of a Humean ‘slave’ to the passions. Moreover, it is the presence of this self-governing reason in each person that Kant thought offered decisive grounds for viewing each as possessed of equal worth and deserving of equal respect.
