Abstract: According to Kant, the arguments of rational psychology are formal fallacies that he calls transcendental paralogisms. It remains heavily debated whether there actually is any formal error in the inferences Kant presents: according to Grier and Allison, they are deductively invalid syllogisms, whereas Bennett, Ameriks, and Van Cleve deny that they are formal fallacies. I advance an interpretation that reconciles these extremes: transcendental paralogisms are sound in general logic but constitute formal fallacies in transcendental logic. By formalising the paralogistic inference, I will pinpoint the error as an illegitimate existential presupposition. Since - unlike transcendental logic - general logic abstracts from all objects, this error can only be detected in transcendental logic.

Abstract: This article addresses the fact of possible and impossible determination of the I or the self-reflective I. In this context, two questions in particular are discussed: What epistemic functions of the I can be legitimately identified, and what kinds of determination of the I are invalid? A theoretical proof of the immortality of a single, persistent substance of the soul (anima) is not possible, because no material substance that corresponds to the I can be found or determined. As this article shows, however, at least a specific form of knowledge of the I, with a view to Kant’s unity of apperception and its actions, can be observed and is therefore epistemically justified.

Abstract: Mendelssohn’s Philosophische Gespräche (Philosophical Dialogues) , first published in 1755, represents his first philosophical work in German and rather surprisingly for a debut, in the first two dialogues of that work Mendelssohn attempts nothing less than a defense of the legacy of the most controversial philosopher of his day, Benedict de Spinoza. In this paper, I attempt to enlarge the context, and if possible to raise the stakes, of Mendelssohn’s discussion in order to bring out what I take to be a much more ambitious project on Mendelssohn’s part, namely, not only the rehabilitation of a fellow Jewish thinker but also the rehabilitation of metaphysics as such by means of a thorough accounting of the Spinozan elements in the Wolffian philosophy. As I will show, framing the project of the Gespräche too narrowly is responsible for obscuring much of what I take to be most original and insightful in Mendelssohn’s use and interpretation of Wolff’s thought, as well as his ultimate purpose in resolving what he regarded as an ongoing crisis in metaphysics that is responsible to no small extent for its widespread neglect.

Abstract: Complex aesthetic perception, according to Mendelssohn’s writings between 1755 and 1771, is most alluring if it showcases a breach in the order of perfection. With this, Mendelssohn introduces a shift in our understanding of the artistic act of imitation: Artistic semblance is always lacking, and a painting that does not point to this fact is, in fact, displeasing. This is also the main reason why we enjoy non-beautiful art: in the artistic rendering of an unpleasant ‘object’ we focus on the artistic act itself, on its formal features, and its effects on us as the perceiver. Thus, a representation that evokes the mixed feelings of pleasure, appreciation, and rejection is superior to ‘pure’ beauty, in that it better refers us to higher forms of perfection: the perfection of the perceiving and creative subject (hence, including both artist and audience). It is the nagging, near-painful impression of mixed sentiments that, according to Mendelssohn, guides our self-perfection, the highest aim of all human endeavors.

Abstract: The paper discusses the concepts of obligation and moral evidence in Mendelssohn’s and Kant’s prize essays. I argue that Mendelssohn departs in significant ways from Christian Wolff’s position, and that Kant intends to overcome Wolffian philosophy with Newtonian methodology while still owing a lot to Wolff and to the project of an ethics within the limits of metaphysics. Although quite akin to Francis Hutcheson’s philosophy, it becomes clear that Kant intended to lay the foundation of an innovative concept of obligation, which shares some similarities with Christian August Crusius’s interpretation of it.

Abstract: Both Mendelssohn and Kant were strong supporters of the separation between church and state, but their arguments differed. Mendelssohn joined many others in following Locke in arguing that only freely arrived at conviction could be pleasing to God, so the state could not serve the purpose of religion in attempting to enforce it: a religious premise for religious liberty. Kant argued for religious liberty as an immediate consequence of the innate right to freedom. I suggest that Kant’s straightforward argument is worth recalling in the present attack on the separation of church and state in the US and elsewhere.

Abstract: Whereas research on Moses Mendelssohn’s Morning Hours has largely focused on the proofs for the existence of God and the elaboration of a purified pantheism in the Second Part of the text, scholars have paid far less attention to the First Part where Mendelssohn details his mature epistemology and conceptions of truth. In an attempt to contribute to remedying this situation, the present article critically examines his account, in the First Part, of different types of truth, different types of knowledge, and the case against idealism. The examination stresses potential but overlooked strengths of his account (e. g., a conception of immediate knowledge that is both far broader than the sensory field and distinctive for having change as its object), questions of ambiguity if not inconsistency in his concepts of existence and substance, and the potential import of these questions for the role he assigns to common sense.
