‘Moral Necessity, Possibility, and Impossibility from Leibniz to Kant.’ Lexicon Philosophicum. (forthcoming) [preprint]
In all three of his major works on moral philosophy, Kant conceives of moral obligation, moral permissibility, and moral impermissibility in decidedly modal terms, namely in terms of moral necessity, moral possibility, and moral impossibility respectively. This terminology is not Kant’s own, however, but has a rather long history stretching back to a group of Spanish Jesuit theologians in the early seventeenth century, and it was used in two contexts: first, in the context of divine and human action to explain how volition can be both metaphysically and physically free and yet morally necessary, and second in a deontic context to refer to moral obligation, permissibility, and impermissibility. In this paper, my first and primary aim is to sketch the way in which four of Kant’s most important German predecessors, namely Leibniz, Christian Wolff, Alexander Gottlieb Baumgarten, and Christian August Crusius, used the language of moral necessity, possibility, and impossibility in both the context of action and obligation. My second, more limited aim is to suggest that Kant’s use of these terms can be clarified by taking this background into consideration.
'Incentives of the Mind: Kant and Baumgarten on the Impelling Causes of Desire.' Archiv für Geschichte der Philosophie. (forthcoming) [preprint] [ published version - open access]
In this paper I propose to shed new light on the role of feeling in Kant’s psychology of moral motivation by focusing on the concept of an incentive (Triebfeder), a term he borrowed from one of his most important rationalist predecessors, Alexander Gottlieb Baumgarten. I argue that, similar to Baumgarten, Kant understands an incentive to refer to the ground of desire and that feelings function as a specific kind of ground within Kant’s psychology of moral action, namely as the ‘impelling cause’ of desire. I claim that this interpretation has several advantages over the alternatives currently on offer in the literature.
'The Rationality of Love: Benevolence and Complacence in Kant and Hutcheson.' Ergo 10 (40), 2023, pg. 1133–56. [published version – open access]
Kant claims that love ‘is a matter of feeling,’ which has led many of his interpreters to argue that he conceives of love as solely a matter of feeling, that is, as a purely pathological state. In this paper I challenge this reading by taking another one of Kant’s claims seriously, namely that all love is either benevolence or complacence and that both are rational. I place Kant’s distinction between benevolence and complacence next to the historical inspiration for it, namely Francis Hutcheson’s very similar distinction, in order to argue that love is rational, for Kant, in that it requires certain rational capacities on the part of the agent. I conclude by illustrating that this has important implications for how we understand Kant’s conception of love more generally.
‘Kant’s Critique of Wolff’s Dogmatic Method: Comments on Gava.’ Journal of Transcendental Philosophy 4 (3), pg. 233– 243. [preprint] [published version]
In Chapter 8 of Kant’s Critique of Pure Reason and the Method of Metaphysics, one of Gabriele Gava’s aims is to argue that Kant’s critique of Wolff’s dogmatic method has two levels: one directed against Wolff’s metaphilosophical views and one attacking his actual procedures of argument. After providing a brief summary of the main claims Gava makes in Chapter 8 of his book, in this paper I argue two things. First, I argue against Gava’s claim that the two forms of dogmatism he distinguished between are incompatible. Second, I suggest, contrary to Gava, that Kant’s critique of these two forms of dogmatism both take place from the metaphilosophical level in the sense that they both target the dogmatist’s beliefs or theory about the method they take themselves to be following.
‘The Volitional Contradiction Interpretation of Kant’s Formula of Universal Law: A Response to Kleingeld.’ Philosophia 51 (2), 2023, pg. 483– 97. [published version - open access]
In this paper I critically engage with Pauline Kleingeld’s ‘volitional self-contradiction’ interpretation of Kant’s formula of universal law. I make three remarks: first, I seek to clarify what it means for a contradiction to be volitional as opposed to logical; second, I suggest that her interpretation might need to be closer to Korsgaard’s ‘practical contradiction’ interpretation than she thinks; and third, I suggest that more work needs to be done to explain how a volitional self-contradiction generates both a ‘contradiction in conception’ and a ‘contradiction in will.’
‘Kant and the Duty to Act from Duty.’ History of Philosophy Quarterly. 39 (1), 2022, pg. 59–75. [preprint] [published version]
Several interpreters argue that Kant believes we have a duty to act “from duty.” If there is such a duty, however, then Kant’s moral theory faces a serious problem, namely that of an allegedly vicious infinite regress of duties. No serious attempt has been made to determine how Kant might respond to this problem and insufficient work has been done to determine whether he even believes we have a duty to act from duty. In this paper I argue that not only does Kant not hold that there is a duty to act from duty, but he also explicitly rejects the idea.
‘Hutcheson’s Theory of Obligation’. Journal of Scottish Philosophy. 20 (2), 2022, pg. 121–142. [preprint] [published version]
In this article I argue both that Hutcheson has a theory of obligation that is different in important ways from the views of his predecessors and that his theory may not be as problematic as critics have claimed. After briefly sketching a picture of the rich conceptual landscape surrounding the concept of obligation in the Early Modern period, I offer an account of Hutcheson’s theory of obligation. Not only does Hutcheson have a view on what previous figures called the source, end, and object of obligation, I illustrate that he focuses on the epistemological question of the origin of the idea of obligation, and he conceives of the necessity involved in obligation in a unique way, namely in terms of the necessity of a perception. I conclude by defending Hutcheson’s theory against three objections.
‘Achtung in Kant and Smith.’ Kant-Studien. 133 (2), 2022, pg. 238-268. [preprint] [published version]
This paper argues that Kant’s concept of ‘respect’ (Achtung) for the moral law has roots in Adam Smith’s concept of ‘regard’ for the general rules of conduct, which was translated as Achtung in the first German translation of the Theory of Moral Sentiments. After illustrating that Kant’s technical understanding of respect appeared relatively late in his intellectual development, I argue that Kant’s concept of respect and Smith’s concept of regard share a basic similarity: they are both a single complex phenomenon with two core aspects, namely an attitude and a feeling. I then suggest that the concept of regard offered Kant a way to deal a problem concerning moral motivation that he was trying to solve at the time he likely first read Smith. I conclude by drawing some implications from the account I have offered for our understanding of Kant’s relation to Smith more generally.
‘Kant and Consequentialism in Context: The Second Critique’s Response to Pistorius.’ Archiv für Geschichte der Philosophie. 103 (2), 2021, pg. 313–340. [preprint] [published version]
Commentators disagree about the extent to which Kant’s ethics is compatible with consequentialism. A question that has not yet been asked is whether Kant had a view of his own regarding the fundamental difference between his ethical theory and a broadly consequentialist one. In this paper I argue that Kant does have such a view. I illustrate this by discussing his response to a well-known objection to his moral theory, namely that Kant offers an implicitly consequentialist theory of moral appraisal. This objection was most famously raised by Mill and Schopenhauer, but also during Kant’s time by Pistorius and Tittel. I show that Kant’s response to this objection in the second Critique illustrates that he sees the fundamental difference between his moral theory and a broadly consequentialist one to be one that concerns methodology.
‘Merely a New Formula? G.A. Tittel on Kant’s Reform of Moral Science.’ Studi Kantiani. 33, 2020, pg. 49–64. [preprint] [published version]
In the first ever commentary on the Groundwork, one of Kant’s earliest critics, Gottlob August Tittel, argues that the categorical imperative is not a new principle of morality, but merely a new formula. This objection has been unjustly neglected in the secondary literature, despite the fact that Kant explicitly responds to it in a footnote in the second Critique. In this paper I seek to offer a thorough explanation of both Tittel’s ‘new formula’ objection and Kant’s response to it, as well as illustrate its significance. I argue that the objection is in fact the third step in a line of argument that Tittel presents in his commentary, and that the objection is best understood within this context. I analyze Kant’s response in the second Critique footnote line-by-line so as to show that Kant both clarifies that it was never his aim to offer a new principle, but only ‘establish’ the principle that common human reason already implicitly employs. Furthermore, I show that Kant uses the opportunity to clarify the sense in which the categorical imperative is a ‘formula [Formel]’, namely as a representation of a complicated and abstract principle, like the moral law, in a way that is easier to understand and apply. I conclude by illustrating the fourth step in Tittel’s line of argument, which makes the overall significance of the ‘new formula’ objection clear: for Tittel, the problem is not that Kant seems to be offering merely a new formula, but that the categorical imperative lacks a foundation.
‘Kant on Moral Satisfaction.’ Kantian Review. 22 (2), 2017, pg. 281–303. [preprint] [published version]
This paper gives an account of Kant’s concept of self-contentment (Selbstzufriedenheit), i.e. the satisfaction involved in the performance of moral action. This concept is vulnerable to an important objection: if moral action is satisfying, it might only ever be performed for the sake of this satisfaction. I explain Kant’s response to this objection and argue that it is superior to Francis Hutcheson’s response to a similar objection. I conclude by showing that two other notions of moral satisfaction in Kant’s moral philosophy, namely ‘sweet merit’ and the highest good, also avoid the objection.
Chapters in Edited Volumes
‘The Principle of Morality in Eighteenth-century German Philosophy.’ The Oxford Handbook of German Philosophy in the Eighteenth Century. Edited by C. W. Dyck, F. Beiser, and B. Look. Oxford University Press. (forthcoming) [preprint]
In this chapter I illustrate that a central topic discussed by nearly every major eighteenth-century German philosopher is the principle of morality, namely what philosophers took to be the supreme norm at the foundation of judging actions to be morally good or evil. Although several figures approached this principle in a broadly similar way by identifying “perfection” as the central concept at work, they differ considerably with respect to important details. Certain common themes are also present in many texts: philosophers differ not only with respect to the content of the principle, but also with respect to the way in which it can be derived, how particular duties can in turn be derived from the supreme principle, and how the principle can be formulated. I begin by outlining Christian Wolff’s influential principle of perfection (Section 1), followed by a consideration of Alexander Gottlieb Baumgarten’s subtle revision of this principle (Section 2) and Christian August Crusius’s theological alternative (Section 3). I then briefly consider the impact that the reception of eighteenth-century British philosophy had on German moral philosophy during the second half of the eighteenth century (Section 4), before considering Moses Mendelssohn’s and Immanuel Kant’s answers to the 1763 Prize Essay Question (Section 5) and Johann August Eberhard’s unique mixture of rationalism and empiricism from the early 1780s (Section 6). I conclude (Section 7) with a brief discussion of Kant’s approach to the principle of morality and the principle of happiness proposed against it by his early empiricist critics.
'Rehberg's Moral Theory.' August Wilhelm Rehberg (1757–1836): Aufklärung zwischen Kritik und Tradition. Edited by S. Klinger and G. Rivero. De Gruyter. (forthcoming) [preprint]
Rehberg makes the astonishing claim that metaphysics caused the French Revolution. He makes this claim because of certain commitments he holds in moral philosophy, such as his is skepticism of pure practical reason: for Rehberg, believing in abstract ideals that have no application in the real, empirical world can lead to dangerous results. While this connection between Rehberg’s politics and his moral philosophy has not gone unnoticed, no serious examination of the moral theory Rehberg develops in his 1787 On the Relation of Metaphysics to Religion has yet been given. This is what I accomplish in this paper. After outlining the place of Rehberg’s moral theory in the Relation, I offer an interpretation of Rehberg’s conception of the principle of morality, his moral psychology, and conception of the good will. I also discuss the relationship between Rehberg’s moral theory and philosophical optimism, namely the idea that we live in the best of all possible worlds, and his account of the human condition as one of conflict between sensibility and rationality in contrast to the nature of the perfect will. The result is a richer appreciation of the systematic nature of Rehberg’s thought, as well as of the broader philosophical background of his political views.
'Kant and Hutcheson on the Psychology of Moral Motivation' in Problems of Reason: Kant in Context. Edited by Antonino Falduto. De Gruyter, 2024, pg. 101–126. [preprint] [published version]
In this paper I argue that Kant’s psychology of moral motivation has less in common with Hutcheson’s view than interpreters have traditionally thought. I first offer an interpretation of the role that feeling, desire, and cognition play in Kant’s account of moral action. I then outline the essential features of Hutcheson’s understanding of desire before arguing that although Kant and Hutcheson share the trivial similarity that even moral action springs from a desire, Kant conceives of the desire at the root of moral action as qualitatively different from all other desires in a number of important ways.
'Wolff on the Duty to Cognize Good and Evil' in Christian Wolff's German Ethics: New Essays. Edited by Sonja Schierbaum, Michael Walschots, and John Walsh. Oxford University Press, 2024, pg. 219– 36. [preprint] [published version]
In this chapter I offer an account of the nature, scope, and significance of Wolff’s claim that human beings have a duty to cognize moral good and evil. I illustrate that Wolff conceives of this duty as requiring that human beings both acquire distinct cognition of good and evil as well as avoid ignorance and error. Although Wolff intends for the duty to be quite demanding, he restricts its scope by, among other things, claiming it primarily concerns those who have the skills, circumstances, and opportunity to acquire such cognition. Wolff calls these individuals the ‘inventors’ of the truths of morality and he considers himself to be such an inventor. I argue that part of the significance of this duty lies in the fact that Wolff conceives of himself as living up to it by writing the German Ethics, thereby sharing the knowledge he has ‘invented’ with others.
(with Sonja Schierbaum) ‘Necessitation, Constraint, and Reluctant Action: Obligation in Wolff, Baumgarten, and Kant’ in Baumgarten and Kant on the Foundations of Practical Philosophy. Edited by C. Fugate and J. Hymers. Oxford University Press, 2024, pg. 71– 89. [preprint] [published version]
Our aim in this paper is to present the distinct ways in which Wolff, Baumgarten, and Kant understand the relationship between necessitation, constraint, and reluctant action in an effort to illustrate the subtle ways in which their conceptions of obligation differ from each another. Whereas Wolff conceives of natural or moral obligation as incompatible with constraint, Baumgarten holds that constraint and reluctant action are, in some instances, compatible with natural obligation. Kant departs from Baumgarten by conceiving of obligation as necessarily involving constraint: as Kant’s reply to Schiller’s famous objection reveals, obligation must take on the character of constraint to reluctant action on account of the fact that human beings possess inclinations that always threaten to impel them in directions that oppose morality.
‘Lambert on Moral Science and Moral Illusion.’ [in German] In Johann Heinrich Lambert (1728-1777): The Mathematization of the Enlightenment. Edited by H.P. Nowitzki, E. Pasini, P. Rumore, and G. Stiening. Berlin: De Gruyter, 2022. pg. 289–300. [preprint] [published version]
This chapter illustrates that Lambert’s works focus not only on mathematical and scientific topics but include reflections on issues in practical philosophy as well. I illustrate, first, that Lamber conceives of moral science [Moral] as the theory of moral judgement and, second, that an important part of this science illustrates how we are to distinguish moral truth from moral illusion.
‘Crusius on Freedom of the Will.’ In Christian August Crusius (1715-1775): Philosophy Between Reason and Revelation. Edited by Frank Grunert and Andree Hahmann. Berlin: De Gruyter, 2021, pg. 189-208. [preprint] [published version]
This chapter offers an account of Crusius’ conception of freedom. In the first part of the chapter I sketch Crusius’ understanding of ‘Thelematology’ or ‘science of the will’ and his conception of the will itself. In the second part of the paper I provide an account of Crusius’ conception of freedom of the will and I focus on two topics: his understanding of freedom as self-determination and his conception of free choice. Contrary to how some of the secondary literature portrays his view, I argue that freedom of the will, for Crusius, is not best described as the freedom to choose otherwise or liberty of indifference. On the contrary, Crusius argues that free choice is rarely indifferent to its choices and is most often strongly inclined towards certain ends that free choice must overcome and choose against.
‘Garve’s Eudaimonism.’ [In German] In Christian Garve (1742-1798): Philosopher and Philologist of the Enlightenment. Edited by Frank Grunert and Gideon Stiening. Berlin: De Gruyter, 2021. pg. 171-182. [preprint] [published version]
In this chapter I evaluate whether Garve was a ‘eudaimonist’, as Kant famously alleged he was. In the first sections of the paper I clarify that eudaimonism can mean either that happiness is the final end of creation, or that human beings are always motived by the desire for happiness, and I discuss Garve’s engagement with Aristotle’s understanding of eudaimonia. I then provide an account of Garve’s understanding of happiness and discuss his theory of motivation before arguing that Garve believes that happiness is both the final end of creation and ultimate end of all human action. I suggest, however, that although Garve is an egoist of sorts, he should not be classified as a hedonist.
‘Kant’s Conception of Selbstzufriedenheit.’ In Nature and Freedom: Proceedings of the 12th International Kant Congress. Edited by Violetta Waibel et al. Berlin: De Gruyter, 2019, pg. 2249–2256. [preprint] [published version]
My primary aim in this paper is thus to clarify Kant’s conception of self-contentment [Selbstzufriedenheit]. I do so by placing the term in the context of Kant’s answer to the objection that virtuous action is only performed in order to experience the feeling of satisfaction that results from so acting, which was put to Kant by his contemporary Christian Garve. I begin by illustrating the main features of Kant’s concept of self-contentment before turning to Garve’s objection and Kant’s response to it. I conclude by clarifying the differences between self-contentment, respect for the moral law, and Kant’s concept of moral pleasure.
‘Hutcheson and Kant: Moral Sense and Moral Feeling.’ Kant and the Scottish Enlightenment. Edited by Elizabeth Robinson and Chris W. Surprenant. London: Routledge, 2017. pg. 36-54. [preprint] [published version]
This chapter gives an account of Hutcheson's conception of the moral sense. This sense is a perceptive faculty that explains our ability both to feel a particular kind of pleasure upon perceiving benevolence, and to appraise such benevolence as morally good on the basis of this feeling. The chapter summarizes Kant's discussion of the moral sense during his pre-Critical period. It explores the main reason why Kant rejects the moral sense as the foundation of moral judgment—namely, because it is incapable of issuing sufficiently universal and necessary judgments of moral good and evil. The chapter also argues that underlying Kant's rejection of the moral sense is the fact that he understands the faculty not as a "sense" proper, but as a "feeling" according to his technical understanding of these terms. It concludes by briefly evaluating what my analysis says about Kant's engagement with Hutcheson.
‘Ernest Sosa and Virtuously Begging the Question.' In Argumentation: Cognition and Community: Proceedings of the 9th Biennial Conference of the Ontario Society for the Study of Argumentation. Edited by Frank Zenker. OSSA: Ontario, 2011. [published version - open access]
This paper discusses the notion of epistemic circularity, supposedly different from logical circularity, and evaluates Ernest Sosa’s claim that this specific kind of circular reasoning is virtuous rather than vicious. I attempt to determine whether or not the conditions said to make epistemic circularity a permissible instance of begging the question could make other instances of circular reasoning equally permissible.

‘Philosophical Writing: The Essay and Beyond.’ Teaching Innovation Projects. 5 (1), 2015. [published version - open access]
The primary method of evaluation in philosophy courses (both undergraduate and graduate) is usually some form of research paper or essay. There is an assumption, however, that the only kind of essay that philosophy students need to learn how to write is the argumentative essay. Indeed, philosophy instructors often consider other forms of writing less significant. This is a detailed plan for a workshop that intends to break down these assumptions by introducing participants (faculty and graduate students) to a variety of essay styles, and to other forms of practical writing that ought to be a part of undergraduate philosophy coursework. The goal of this workshop is to encourage instructors to create more purposeful and creative writing assignments in their own future courses.
