Kant’s formula of universal law (FUL) is standardly understood as a test of the moral permissibility of an agent’s maxim: maxims which pass the test are morally neutral, and so permissible, while those which do not are morally impermissible. In contrast, I argue that the FUL tests whether a maxim is the cause or determining ground of an action at all. According to Kant’s general account of causality, nothing can be a cause of some effect unless there is (...) a law-like relation between the putative cause and effect. Applied to the case of action, no maxim can be the cause of an agent’s action unless there is a law-like relation between maxims of that kind and actions of that kind. The special capacity to act according to maxims as law-like causes is what Kant calls a will; the basic constitutive principle of the will is a non-normative principle I call the categorical declarative. While the actions of a perfectly good will would be described by the categorical declarative alone, human action is determined not only by the causality of the will, but also by competing causes, namely those stemming from inclination. There is thus need for a causal test for putative maxims. The test contained in the FUL is meant to determine whether an action could be grounded solely on the agent’s maxim, or whether it requires a cause external to the will. This account permits one to build eventual distinctions concerning the morality of actions on prior and independent distinctions concerning their causality. (shrink)

This paper provides a methodologically original construction of Kant’s “Formula of Universal Law” . A formal structure consisting of possible worlds and games—a “game frame”—is used to implement Kant’s concept of a maxim and to define the two tests FUL comprises: the “contradiction in conception” and “contradiction in the will” tests. The paper makes two contributions. Firstly, the model provides a formal account of the variables that are built into FUL: agents, maxims, intentions, actions, and outcomes. This establishes (...) a clear benchmark for understanding how the mechanics of FUL actually work. Secondly, the analysis of the resulting framework sheds new light on discussions about the implications of FUL. On the basis of this, we suggest a move to “comprehensive Kantianism’, which is the application of FUL to systems of maxims rather than to isolated maxims. (shrink)

The formula of universal law (FUL) is a natural starting point for philosophers interested in a Kantian perspective on the morality of abortion. I argue, however, that FUL does not yield much in the way of promising or substantive conclusions regarding the morality of abortion. I first reveal how two philosophers' (Hare's and Gensler's) attempts to use Kantian considerations of universality and prescriptivity fail to provide analyses of abortion that are either compelling or true to Kant=s understanding of (...) FUL. I then turn to some recent interpretations of Kant=s FUL contradiction in conception (CC) and contradiction in will (CW) tests. I argue that none of the interpretations of the CC testBincluding the practical interpretation favored by KorsgaardBdoes much to reveal moral problems with maxims of abortion. The CW test (as developed by Herman) is more helpful. Nevertheless, I argue that neither by considering abortion maxims as a subset of maxims of convenience killing, nor by considering such maxims as maxims of refusing to aid, can the CW test generate a general prohibition of abortion. At best, the CW test illuminates the abortion issue because by forcing us to think about how killing a fetus differs from killing other human beings, what attitudes we may reasonably have toward a fetus, and whether Kant's moral theory must be amended to do justice to the problem of abortion. But to pursue these questions, we must look beyond FUL; Kant’s formula of humanity and doctrine of virtue may well have more to offer. (shrink)

Kant’s most prominent formulation of the Categorical Imperative, known as the Formula of Universal Law (FUL), is generally thought to demand that one act only on maxims that one can will as universal laws without this generating a contradiction. Kant's view is standardly summarized as requiring the 'universalizability' of one's maxims and described in terms of the distinction between 'contradictions in conception' and 'contradictions in the will'. Focusing on the underappreciated significance of the simultaneity condition included in (...) the FUL, I argue, by contrast, that the principle is better read as requiring that one be able to will two things simultaneously without self-contradiction, namely, that a maxim be one's own and that it be a universal law. This amounts to a new interpretation of the FUL with significant interpretive and philosophical advantages. (shrink)

One of the most important difficulties facing Kant’s Formula of Universal Law (FUL) is its apparent inability to show that it is always impermissible to kill others for the sake of convenience. This difficulty has led current Kantian ethicists to de-emphasize the FUL or at least complement it with other Kantian principles when dealing with murder. The difficulty stems from the fact that the maxim of convenience killing fails to generate a ‘contradiction in conception’, producing only a ‘contradiction (...) in the will’ when subjected to the two-fold test associated with the FUL. This result is thought to imply that the FUL allows us sometimes to kill for the sake of convenience. In this essay, I argue that the very diagnosis of the problem rests on a mistake, and that if the maxim of convenience killing generates a contradiction in the will, then acting on it is never permissible.

According to the standard reading of Kant's formula of universal law (FUL), positive duties can be derived from FUL. In this article, I argue that the standard reading does not work. In the first section, I articulate FUL and what I mean by a positive duty. In the second section, I set out an intuitive version of the standard reading of FUL and argue that it does not work. In the third section, I set out a more rigorous (...) version of the standard reading of FUL and argue that even this more rigorous version does not work. (shrink)

My aim in this note is to shed light on ways of interpreting Kant’s Formula of Universal Law (FUL), by looking at relevant similarities and differences between Pauline Kleingeld and Mark Timmons. I identify both their readings as a formal interpretation of Kant’s FUL, in contrast to the substantive interpretations that favor a robust conception of rational agency as a necessary requirement for moral deliberation. I highlight the benefits that arise from Kleingled’s interpretation in showing the immediacy involved (...) in the volitional self-contradiction when universalizing a maxim. Alongside Timmons, I address a question as to whether Kleingeld’s interpretation is completely free from at least a minimal set of assumptions about practical deliberation more broadly, that seem to play a role in generating the volitational self-contradiction she is defending. I close by raising some skeptical worries about the capacity of this kind of contradiction to translate into a moral judgment triggering action. (shrink)

In the First Section of the Groundwork of the Metaphysics of Morals, Kant argues that a good-willed person “under subjective limitations and hindrances” (G 397) is required “never to act except in such a way that [she] could also will that [her] maxim should become a universal law” (G 402).2 This requirement has come to be known as the Formula of Universal Law (FUL) version of the Categorical Imperative, an “ought” statement expressing a command of reason that (...) “represent[s] an action as objectively necessary of itself, without reference to another end” (G 414). The question of how to understand and apply the FUL has received a great deal of attention in recent years. But Kant’s reasoning for the claim that a good-willed person (of a certain kind) acts in accordance with the FUL has not been investigated with the same degree of thoroughness. My purpose in this paper is to render the structure of Kant’s argument perspicuous, and thereby contribute to its proper evaluation by identifying its true strengths and weaknesses.3 Let us call Kant’s argument “K” and its conclusion “C”. The task at hand requires identification of K’s premises and of the reasoning by means of which C is derived. One of the advantages of clarifying K’s structure in this way is that doing so permits us to answer questions that continue to puzzle even the most sympathetic readers of the First Section. Some of these questions concern three “Propositions” to which Kant 1 draws our attention in the course of his presentation. The First Proposition (call it “P1”) is left unstated, but most commentators agree that it (or at least part of it) should be rendered as follows: (P1) A human action has moral worth only if it is done from duty.4 Kant states the other two propositions (call the Second “P2” and Third “P3”) explicitly: (P2) An action from duty has its moral worth not in the purpose to be attained by it but in the maxim in accordance with which it is decided upon. (G 399). (shrink)

Ever since Hegel famously objected to Kant’s universalization formulations of the Categorical Imperative on the grounds that they are nothing but an empty formalism, there has been continual debate about whether he was right. In this paper I argue that Hegel got things at least half-right: I argue that even if negative duties (duties to omit actions or not to adopt maxims) can be derived from the universalization formulations, positive duties (duties to commit actions or to adopt maxims) cannot. The (...) paper is divided into three main sections. In the first, I set out the procedures generally accepted among Kantians for deriving positive duties from the universalization formulations. In the second, I set out the arguments from section 1 in more detail and explain why they do not work. In the third, I examine a strategy that might be used to supplement the arguments from section 2 and I argue that it also does not work. (shrink)

In his Groundwork of the Metaphysics of Morals, Kant’s desiderata for a supreme principle of practical reasoning and morality require that the subjective conditions under which some action is thought of as justified via some maxim be sufficient for judging the same action as justified by any agent in those conditions. This describes the kind of universalization conditions now known as moral supervenience. But when he specifies his “formula of universal law” (FUL) Kant replaces this condition with a (...) quite different kind of universality: the judgment that some agent could rationally (i.e., without willing the frustration of his own valued ends) will his adoption of some maxim under the condition that this would cause all agents in his world to adopt it as well. Our wills typically lack this efficacy, so requiring that our wills conform to what would be rational for a hypothetical agent in this situation to will is a heteronomous requirement. Several intuitively wrong maxims pass Kant’s test but fail the test of supervenience, because they generate no contradiction in a world of universal compliance but do so in non-ideal worlds, demonstrating the inadequacy of the FUL and the logical superiority of moral supervenience. -/- NOTE: in the published version of this article's title, "became" is mistakenly, and ungrammatically, replaced with "become.".

Kant offers the following argument for the formula of humanity (FH): Each rational agent necessarily conceives of her own rational nature as an end in itself and does so on the same grounds as every other rational agent, so all rational agents must conceive of one another's rational nature as an end in itself. As it stands, the argument appears to be question-begging and fallacious. Drawing on resources from the formula of universal law (FUL) and Kant's claims (...) about the primacy of duties to oneself, I propose a contractualist reconstruction of this puzzling line of reasoning. (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.

My aim in this paper is to explore different ways of understanding Kant’s Formula of Humanity as a formal principle. I believe that a formal principle for Kant is a principle that is constitutive of some domain of cognition or rational activity. It is a principle that both constitutively guides that activity and serves as its internal regulative norm. In the first section of this essay, I explain why it is desirable to find a way to understand the (...) class='Hi'>Formula of Humanity as a formal principle in this sense. In sections II and III I discuss two interpretive approaches to Kant’s idea that rational nature or humanity is an end in itself, both of which may be construed as treating the Formula of Humanity as a formal principle. By focusing on the notion of formal principle, I hope to raise a set of issues about how to understand the idea of rational nature or humanity as an end in itself, and about the relation of the Formula of Humanity [FH] to the Formula of Universal Law [FUL]. I do not resolve the issues in this paper, though I briefly sketch some resolution at the end. (shrink)

According to Kant, the supreme principle of morality is: “act only according to that maxim through which you can at the same time will that it become a universal law” (G 4:421). This principle has come to be known as the Formula of Universal Law (“FUL”). Few philosophers believe it succeeds. But, I argue, few philosophers have understood what FUL means. This dissertation offers a full defense of FUL. It is, in fact, the supreme principle of morality—and (...) it can successfully derive a viable theory of permissible action and virtuous willing. Kant was right. Chapter 1 considers FUL’s role in relation to Kant’s subsequent formulations of the Categorical Imperative and the broader architectonic of duty he sets up in the Metaphysics of Morals. I argue that Kant’s formulations are equivalent insofar as they are each expressions of the very same moral principle. And I suggest that FUL’s two tests correspond to Kant’s later distinction between duties of right and duties of virtue. Thus, FUL’s contradiction-in-conception test can be used to derive duties governing permissible action, and FUL’s contradiction-in-the-will test can be used to derive duties governing virtuous willing. This sets up the framework for the remainder of the dissertation. Chapters 2 and 3 together interpret and defend Kant’s account of permissible action. In Chapter 2, I argue that we should fundamentally reconceive of the nature and purpose of Kant’s permissibility criterion. Kant’s contemporary interpreters have adopted too psychologistic an account of the maxim. Kantian maxims have little to do with the motivating principles of actual agents. Relying on Kant’s historical context and his account of maxims in rational agency, I argue that FUL tests means-end principles which describe act-types. When its permissibility test is applied to such principles, it can viably derive general duties. Chapter 3 continues this positive account of Kant’s permissibility test and defends it from common objections. I argue that the contradiction-in-conception test rejects an act-type when it would be inconceivable for all rational agents to be directly governed by the type’s means-end imperative as a universal practical law. So understood, FUL condemns act-types because: (1) they are hypocritically self-serving, (2) they inflict agential harm on other agents, or (3) they inflict self-harm motivated by self-love. I defend FUL’s derivations against such act-types against common criticisms, such as that they are circular or overbroad. Turning to prominent objections against Kant’s account of permissible action, I then argue that FUL correctly rules out all and only impermissible actions. Moreover, its conclusions are both nuanced and normatively defensible. In Chapter 4, I turn to Kant’s virtue ethics. I begin by considering the demands of Kantian virtue. I argue that we should reject accounts on which duties of virtue are merely less restrictive duties governing permissible action. Instead, I argue, they represent genuinely virtue-ethical requirements to promote morally worthy ends, namely, the ends of our own perfection and others’ happiness. I show that all of Kant’s duties of virtue can ultimately be traced back to one of these required ends. Then, I argue that FUL’s contradiction-in-the-will test can successfully derive our positive obligation to set the ends of virtue. I conclude that FUL is successful not only as a standard of permissibility, but also as the supreme principle of virtue. (shrink)

This article begins with the claim that the Formula of Universal Law, interpreted as a test of the deontic status of actions, can't be made to work. If not, then one might wonder whether what other work it might do in the overall economy of Kant's ethics. I defend what I call the "formal constraint" interpretation of FUL, explaining how it can figure in a defense of the Formula of Humanity, and its psychological significance in moral thinking.

This study examined representations of Kant’s theory of ethics in three applied ethics open textbooks. In two of the three textbooks, the concept of autonomy, which is the foundational concept in Kant’s theory, was generally missing. The three textbooks introduced and explained Kant’s emphasis on duty, but only one of them explicated the connection between duty and autonomy. All three textbooks introduced and explained Kant’s concept of universalizability. All of them also introduced the Formula of Humanity (FH), however, none (...) of them explained what Kant meant by “humanity” in that formula (Kant defined humanity as “the capacity to set ends”). The study concluded with recommendations for textbook authors on how to write valid and comprehensive introductions to Kant’s theory. The recommendations were the following: First, Kant’s theory should be introduced as a theory of both autonomy and duty. Second, the Formula of Universal Law (FUL) should be introduced as a tool that supports agents in practicing autonomy, not as a formula that should be blindly followed; blindly following formulas contradicts with Kant’s commitment to the unconditional respect of human autonomy. Finally, when introducing Kant’s command to treat humanity as an end-in-itself, it is important to explain what he meant by humanity and by end-in-itself. (shrink)

This article examines the role of maxims in Kantian ethics. Maxims are propositions that describe individual actions as instances of general rules. Because Kantian ethics evaluates the morality of actions by testing the actions’ maxims, it is important to formulate the maxim well. I begin by (1) investigating how maxims relate to actions. Next, I (2) review how Kantian ethics tests maxims, focusing on the Formula of Universal Law (FUL). I engage Kant’s conceptions of determining and reflecting judgment (...) from the Third Critique to illuminate the role of judgment in crafting and testing maxims. Then, I present (3) my interpretation of how to craft maxims in a Kantian context: In condition C, I do action A. I apply my interpretation to (4) several examples, including Kant’s own, Kant’s critics, and contemporary Kantians. I (5) consider several objections and (6) explain how this interpretation of crafting maxims has helped my applied ethics students. (shrink)

Acts of violence and murder have historically proved difficult to accommodate in standard accounts of the formula of universal law (FUL) version of Kant’s Categorical Imperative (CI). In “Murder and Mayhem,” Barbara Herman offers a distinctive account of the status of these acts that is intended to be appropriately didactic in comparison to accounts like the practical contradiction model. I argue that while Herman’s account is a promising one, the distinction she makes between coercive and non-coercive violence and (...) her response to concerns with the classification of the latter as imperfect duties raise significant questions about the status of some duties. I suggest that we look, instead, to Kant’s treatment of suicide in The Metaphysics of Morals for an account of norms of non-violence and, in particular, to the connection between this duty and concerns with inner freedom and moral health. I argue that we can use this account to inform our general understanding of duties prohibiting killing and violence, and that the resulting account is a promising one. (shrink)

The article defends three claims regarding the relation between the different formulas of the categorical imperative. On its prevailing reading, FUL gives different moral guidance than FH; left answered, this problem is an argument for adopting a competing perspective on FUL. The prohibitions and commands of the formulas should be taken to be extensionally the same; but FKE adds a dimension missing from the others, gained by uniting their perspectives, namely, bringing the variety of moral laws into systematic unity. The (...) grammatically ambiguous phrase inGMS, 4: 436.9–10 claims that FA alone unites the other formulas in itself. (shrink)

These comments raise two main points based on Walschots’s response to Kleingeld’s ‘volitional’ interpretation of the contradiction involved in Kant’s Formula of Universal Law. The first concerns Walschots’s claim that, contrary to Kleingeld’s own account, her interpretation must in fact assume at least one essential purpose of the will, namely happiness. While Walschots characterises happiness as a necessary end of all rational beings, I clarify on textual grounds that, for Kant, happiness can be safely assumed as an actual (...) end of all rational finite beings. The second point regards Walschots’s claim that Kleingeld’s interpretation should be clearer on the two ways in which a volitional self-contradiction can arise. Drawing on Walschots’s instructive discussion, and on Timmermann’s conservative defence of a more traditional interpretation of the Formula against Kleingeld’s innovative proposal, I cautiously suggest that Kleingeld might end up having to accommodate three contradictions: the traditional contradictions in conception and in the will, and her volitional self-contradiction.

Among the most surprising claims in The Methods of Ethics is Sidgwick’s assertion that his key ethical axioms are corroborated by Kant. This article analyses Sidgwick’s claim that his axioms of justice and benevolence closely correspond to particular features in Kant. I shall argue that his claim of agreement with Kant was a serious overstatement. In particular, the restrictions which Sidgwick places on his acceptance of Kant’s universal law formula of the categorical imperative (FUL) seem to call into (...) question whether the alleged convergence with the axiom of justice has a solid basis. Further, Sidgwick seemed unaware of a crucial aspect of Kant’s conception of the humanity formula that constitutes a substantial divide between their views on benevolence. The upshot is that the divide between Kantian and Sidgwickian ethics appears deeper than Sidgwick seemed to realize. This analysis is confirmed by Sidgwick’s famous worries regarding freedom and the existence of God in Kant’s work. (shrink)
