I want to distinguish between maxims at three levels of abstraction. At the first level are what I shall call individual maxims, or i‐maxims: maxim tokens as adopted by particular rational beings. At the second level are abstract maxims, or a‐maxims: abstract principles distinct from any individual who adopts them. At the third level are maxim kinds, or k‐maxims: sets of various action‐guiding principles that are grouped on the basis of their content. In this paper, I argue for the thesis (...) that i‐maxims are the locus of assessment in Kant's ethics. (shrink)

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.

Although maxims are central to Kant’s ethical theory, his account of them remains obscure. We can make progress towards understanding Kantian maxims by examining not only their role as the object of moral judgement but also their connection to freedom of the will and causality. This requires understanding maxims as causal laws that explain the actions that we impute to agents. In this way, they are analogous to causal laws of nature, but they are limited in scope to the agents (...) who are responsible for them. Understanding maxims in this way explains our limited epistemic access to them and helps to clarify Kant’s account of virtue and character as well as how they mediate the relationship between practical and theoretical reason.

Should you reduce your energy consumption? Tragically enough, it may be better for you, and for everyone involved, to refrain from doing so even if you care about the climate. Given this tragedy, why cooperate? This paper defends the view that not cooperating is morally problematic because it is not universalizable (in a Kantian sense). That is, I will argue that we have universalizability-based reasons to cooperate as long as we have a preference for ‘collective success’ (e.g. a sustainable planet). (...) The problem is that defectors let others fix the problem for them, and in this way make an unfair exception of themselves. Moreover, even when selected agents might not share this preference, they still have to cooperate for the sake of others. (shrink)
