Kant's Works in Pre-Critical Philosophy

In his Beweisgrund (1762), Kant presents a sketch of "the only possible basis" for a proof of God's existence. In this essay, I attempt to present that proof as a valid and sound argument for the existence of God.

This paper proposes a novel reading of Kant’s account of the dependence of possibility on God in the pre-Critical Beweisgrund. I argue that Kant has a theistic-potentialist conception of the way God grounds possibility, according to which God grounds possibility by his understanding and will. The reason is that Kant accepts what I call the Principle of Possible Existence: If something is possible, then it is possible that it exists. Furthermore, I explore the connection between causal powers and possibility, the (...) influence of Crusius on Kant, and the significance of the distinction between internal and external possibility.

This chapter discusses Kant's 1763 "possibility proof" for the existence of God. I first provide a reconstruction of the proof in its two stages, and then revisit my earlier argument according to which the being the proof delivers threatens to be a Spinozistic-panentheistic God—a being whose properties include the entire spatio-temporal universe—rather than the traditional, ontologically distinct God of biblical monotheism. I go on to evaluate some recent alternative readings that have sought to avoid this result by arguing that the (...) relevant facts about real modality can be ultimately grounded in God’s powers or thoughts – or that Kant just leaves the grounding relations mysterious. I argue that the textual and philosophical costs of each of these alternative readings are formidable. The chapter concludes with a discussion of the fate of the proof in the critical period. Some commentators think that it disappears altogether, or that it is downgraded such that it produces a mere regulative idea of God as the most real being. I suggest that the proof survives but that the mode of assent it licenses towards its conclusion changes from knowledge to a certain kind of Belief (Glaube). (shrink)

This chapter discusses the relation between Kant’s views on the foundations of syllogistic inference in ‘The False Subtlety of the Four Syllogistic Figures’, the views of eighteenth-century German authors who wrote on syllogism, and the conception of metaphysics that Kant developed in 1762-1764. Kant’s positions are, on the whole, rather original, even though they are not as independent from the intellectual context as Kant’s later, Critical philosophy. Despite Kant’s polemical tone, his views on syllogism are not primarily motivated by polemical (...) purposes. They are strongly influenced by his views on the method of metaphysics. (shrink)

Much recent attention has been paid to Kant’s account of the unity of space in the Critique of Pure Reason, not least because of the significant implications of that view for other key critical-period doctrines. But far less attention has been paid to the development of Kant’s account of the unity of space. This paper aims to offer a systematic account of Kant’s pre-critical account of the unity of space. On the view presented herein, Kant’s early account of the unity (...) of space is deeply rooted in his pre-critical cosmological views. In particular, I argue that Kant sees the unity of space as grounded in the cosmological unity of the world of substances, which is itself rooted in the divine conservation of all substances in relations of mutual causal dependence. I contend that the seeds of this view are present in the late 1740s and 1750s, but that this view receives its fullest and most complete expression in the 1770 Inaugural Dissertation. The final section of the paper considers the fate of Kant’s pre-critical account of the unity of space. I contend that the theory is excluded from the Critique of Pure Reason in light of the strict epistemological strictures adopted in that text. But considerable textual evidence shows that Kant continues to aver the theory throughout the 1770s and 1780s in the looser epistemic context of his lectures. I contend, then, that this theory is not abandoned at all. Rather, like Kant’s 1763 proof of the existence of God, it is epistemically demoted: it is Kant’s preferred view, but one that falls short of the demanding epistemic standards of the critical philosophy.

The consensus is that in his 1755 Nova Dilucidatio, Kant endorsed broadly Leibnizian compatibilism, then switched to a strongly incompatibilist position in the early 1760s. I argue for an alternative, incompatibilist reading of the Nova Dilucidatio. On this reading, actions are partly grounded in indeterministic acts of volition, and partly in prior conative or cognitive motivations. Actions resulting from volitions are determined by volitions, but volitions themselves are not fully determined. This move, which was standard in medieval treatments of free (...) choice, explains why Kant is so critical of Crusius’s version of libertarian freedom: Kant understands Crusius as making actions entirely random. In defense of this reading, I offer a new analysis of the version of the principle of sufficient reason that appears in the Nova Dilucidatio. This principle can be read as merely guaranteeing grounds for the existence of things or substances, rather than efficient causes for states and events. As such, the principle need not exclude libertarian freedom. Along the way, I seek to illuminate obscure aspects of Kant’s 1755 views on moral psychology, action theory, and the threat of theological determinism. (shrink)

It is widely held that, in his pre-Critical works, Kant endorsed a necessitation account of laws of nature, where laws are grounded in essences or causal powers. Against this, I argue that the early Kant endorsed the priority of laws in explaining and unifying the natural world, as well as their irreducible role in in grounding natural necessity. Laws are a key constituent of Kant’s explanatory naturalism, rather than undermining it. By laying out neglected distinctions Kant draws among types of (...) natural law, grounding relations, and ontological levels, I show that his early works present a coherent and sophisticated laws-first account of the natural order.

This is a chronological commentary on Kant’s writings through 1769 whose aim is to reveal that the ‘secret thorn’ driving Kant’s thought through its twists and turns is the scripture-based faith of the German Protestant tradition.

This book provides an account of the unity of Immanuel Kant’s early metaphysics, including the moment he invents transcendental idealism. Matthew Rukgaber argues that a division between “two worlds”—the world of matter, force, and space on the one hand, and the world of metaphysical substances with inner states and principles preserved by God on the other—is what guides Kant’s thought. Until 1770 Kant consistently held a conception of space as a force-based material product of monads that are only virtually present (...) in nature. As Rukgaber explains, transcendental idealism emerges as a constructivist metaphysics, a view in which space and time are real relations outside of the mind, but those relations are metaphysically dependent on the subject. The subject creates the simple “now” and “here,” thus introducing into the intrinsically indeterminate and infinitely divisible continua of nature a metric with transformation rules that make possible all individuation and measurement.

In this paper I consider Tetens' reaction to Kant's Inaugural Dissertation in his two most important philosophical works, the essay “Über die allgemeine speculativische Philosophie” of 1775 and the two-volume Philosophische Versuche of 1777. In particular, I focus on Tetens’ critical discussion of Kant's account of the acquisition of concepts of space and time.

Autonomy is one of the central concepts of contemporary moral thought, and Kant is often credited with being the inventor of individual moral autonomy. But how and why did Kant develop this notion? The Emergence of Autonomy in Kant's Moral Philosophy is the first essay collection exclusively devoted to this topic. It traces the emergence of autonomy from Kant's earliest writings to the changes that he made to the concept in his mature works. The essays offer a close historical and (...) philosophical analysis of what prompted Kant to develop his conception of autonomy, charting the historical background which prompted his search, and thoroughly analysing different stages of his writings in order to see which element of autonomy was introduced at which point. The resulting volume will be of interest to both scholars and students of Kantian moral philosophy, as well as to anyone interested in the subject of autonomy. (shrink)

The Role of the Notion of Truth in the Project of Kant’s Critical Philosophy [English] The discussion about Kant’s theory of truth usually revolves around his ascription to some version of the coherence or correspondence theory of truth, and the matching criteria of truth. These discussions often deliberate which theory of truth is most appropriate given the critical principles. Instead, this paper aims to exhibit, through the evolution of Kant’s notion of truth in his precritical years and through the project (...) of a transcendental logic, the intrinsic relation between the notion of truth and the very principles of critical philosophy; and to raise again the questions about the definition and the criteria of truth, but in the framework of the question of the possibility of truth. [Español] La discusión en torno a la teoría kantiana de la verdad suele girar alrededor de las preguntas —íntimamente relacionadas entre sí— por la adscripción de Kant a una versión coherentista o correspondentista de la verdad y por los correspondientes criterios de verdad. Estas discusiones suelen ponderar qué teoría de la verdad resulta más adecuada dados ya los principios críticos. En contraste con esto, este trabajo pretende mostrar, a través de la evolución de la noción de verdad del Kant precrítico y del proyecto de una lógica trascendental, la vinculación intrínseca de la noción de verdad con los principios mismos de la filosofía crítica, y replantear las preguntas por la definición y el criterio de verdad en el marco de la pregunta por la posibilidad de la verdad.

Kosmos und Subjektivität – dieses Begriffspaar stellt sogleich einen Antagonismus vor, denn Subjektivität konstituiert sich alleine im irreduziblen Bruch mit der kosmischen Einheit. Gegen Ende des 18. Jahrhunderts kommt es zu diesem Bruch, der sich durch ein Ineinanderwirken von wissenschaftlichen, philosophischen und ästhetischen Diskursen auszeichnet. Als entscheidender Schritt dieser Entwicklung, so die These der Untersuchung, lässt sich die Frühromantik verstehen: Sie insistiert zum einen auf dem Bruch mit der tradierten Vorstellung des Kosmos und entdeckt darin die Möglichkeitsbedingung moderner Subjektivität. Zum (...) anderen hat sie die Erfahrung einer solchen Destruktion noch zur Voraussetzung ihrer eigenen Poetik. (shrink)

A review of Nicholas Stang's 2016 book, Kant's Modal Metaphysics.

Kant’s introduction in the Kritik der reinen Vernunft (KrV) of a spontaneity proper to the understanding is often thought to be one of the central innovations of his Critical philosophy. As I show in this paper, however, a number of thinkers within the 18th century German tradition in the time before the KrV (including the pre-Critical Kant himself) had already developed a robust conception of the spontaneity of the mind, a conception which, in many respects lays the groundwork for Kant’s (...) later, rather more influential account. To illustrate this, I consider three accounts of the spontaneity of the mind—those of Crusius, the pre-Critical Kant, and Tetens—which, while distinct, nonetheless relate to and explicitly draw upon one another in important ways, forming as it were the interconnected and, thus far, largely overlooked pre-Critical context for Kant’s discussion of the spontaneity of the understanding in the KrV. As I conclude, while Kant’s own account of the spontaneity of the understanding, and particularly of the I think clearly departs from these accounts, it nonetheless continues to connect in significant ways with the trailblazing discussions of his immediate predecessors.

Andrew Chignell and Omri Boehm have recently argued that Kant’s pre-Critical proof for the existence of God entails a Spinozistic conception of God and hence substance monism. The basis for this reading is the assumption common in the literature that God grounds possibilities by exemplifying them. In this article I take issue with this assumption and argue for an alternative Leibnizian reading, according to which possibilities are grounded in essences united in God’s mind (later also described as Platonic ideas intuited (...) by God). I show that this view about the distinction between God’s cognition of essences as the ground of possibility and the actual world is not only explicitly stated by Kant, but is also consistent with his metaphysical picture of teleology in nature and causality during the pre-Critical period. Finally, I suggest that the distinction between the conceptual order of essences embodied in the idea of God and the order of the objects of experience plays a role in the transition into the Critical system, where it is transformed into the distinction between the intelligible and the sensible worlds.

Leibniz’s main thesis regarding the nature of space is that space is relational. This means that space is not an independent object or existent in itself, but rather a set of relations between objects existing at the same time. The reality of space, therefore, is derived from objects and their relations. For Leibniz and his successors, this view of space was intimately connected with the understanding of the composite nature of material objects. The nature of the relation between space and (...) matter was crucial to the conceptualization of both space and matter. In this paper, I discuss Leibniz’s account of relational space and examine its novel elaborations by two of his successors, namely, the young Immanuel Kant and the Croat natural philosopher Roger Boscovich. Kant’s and Boscovich’s studies of Leibniz’s account lead them to original versions of the relational view of space. Thus, Leibniz’s relational space proved to be a philosophically fruitful notion, as it yielded bold and intriguing attempts to decipher the nature of space and was a key part in innovative scientific ideas.

The Dreams of a Spirit-Seer and the one reality in which we live [English] Traüme eines Geistersehers usually constitutes a problematic work for Kant’s scholars for its unusual style and for the apparent break with the problems that occupied him at the beginning of the 1760s. However, this work is to a large extent the natural outcome of those themes, especially of the search for an appropriate method for metaphysics. In this paper we are particularly interested in highlighting two ideas (...) that appear there: the conception of metaphysics as a study of limits and intersubjectivity. As we will see, the backdrop of these issues and the idea that gives cohesion to Traüme is the need to base our knowledge on a single world that we all inhabit, and to which we all have equal access. Swedenborg, who embodies the opposite idea of being a privileged inhabitant of two worlds, serves as a reason to compare his visions with the excesses of metaphysics, and the "dream worlds" that he constructs. [Español] El escrito Traüme eines Geistersehers suele constituir una obra problemática para los intérpretes de Kant por su inusual estilo y por el aparente rompimiento con los problemas que lo ocupaban a principios de 1760. Sin embargo, esta obra es en buena medida el desenlace natural de aquellos temas, en especial de la búsqueda de un método apropiado para la metafísica. En este trabajo nos interesa particularmente destacar dos ideas que ahí aparecen: la concepción de la metafísica como estudio de los límites y el tema de la intersubjetividad. Como veremos, el telón de fondo de estos temas y la idea que da cohesión en general a los Traüme es la necesidad de fundar nuestro conocimiento en un único mundo que todos habitamos, y al que todos tenemos acceso por igual. Swedenborg, que encarna la idea contraria al ser habitante privilegiado de dos mundos, sirve de motivo para comparar sus visiones con los excesos de la metafísica, y los “mundos soñados” que esta construye.

KantObservations on the Feeling of the Beautiful and the Sublime’ reveal a deep concern with the way in which the human drives to equality and unity lead inevitably to a drive for honour and its attendant delusions. He developed his thinking about these problems in the context of his reading of Rousseau. In his published Dreams of a Spirit-Seer, Kant tries to overcome the influence of the drive for honour by appealing to a metaphysics that is critical of itself. The (...) problem is how to distinguish what is grounded in reason when that reason is so easily influenced by others. (shrink)

In der Kritik der Urteilskraft vertritt Kant noch die analogische Beziehung zwischen Schönheit und Sittlichkeit (KU, AA 05: 351–354). Aber wir befinden uns hier in einem ganz anderen Zusammenhang. Und dies nicht nur, weil die Erörterung dieser analogischen Beziehung eine Lösung für das Problem der Verknüpfung zwischen theoretischer und praktischer Vernunft beansprucht. Die Reflexionen in den Vorlesungen über Anthropologie über die pragmatische Dimension des Geschmacks setzten die Möglichkeit dieser Verknüpfung bereits voraus, bevor Kant eine kritische Begründung derselben erreichte. Wir dürfen (...) aber diese Reflexionen nicht als das Ergebnis unreifer Versuche zur Lösung dieses kritischen Problems der Rationalitätstheorie Kants deuten. Während der Paragraph 59 der Kritik der Urteilskraft Teil der spekulativen Philosophie ist, wird die Kritik des Geschmacks in den Vorlesungen über Anthropologie vielmehr insofern sinnvoll, da sie zu einem pragmatischen, populären und aufgeklärten Bildungsprogramm der Anthropologie Kants gehört.

Andrew Chignell recently proposed an original reconstruction of Kant's ‘Only Possible Argument’ for the existence of God. Chignell claims that what motivates the ‘Grounding Premise’ of Kant's proof, ‘real possibility must be grounded in actuality’, is the requirement that the predicates of a really possible thing must be ‘really harmonious’, i.e. compatible in an extra-logical or metaphysical sense. I take issue with Chignell's reconstruction. First, the pre-Critical Kant does not present ‘real harmony’ as a general condition of real possibility. Second, (...) the real harmony requirement is not what motivates the ‘Grounding Premise’ of the proof. Instead, this premise is sufficiently motivated by what Chignell labels the ‘content’ requirement. Finally, Kant's downgrading of the proof in his Critical period is not based on a concern regarding the real harmony of the predicates of God, but on his Critical restrictions on cognition in general and modal cognition in particular.

I reply to recent criticisms by Uygar Abaci and Peter Yong, among others, of my reading of Kant's pre-Critical of God's existence, and of its fate in the Critical period. Along the way I discuss some implications of this debate for our understanding of Kant's modal metaphysics and modal epistemology generally.

This paper defends the Principle of Sufficient Reason, taking Baumgarten as its guide. The primary aim is not to vindicate the principle, but rather to explore the kinds of resources Baumgarten originally thought sufficient to justify the PSR against its early opponents. The paper also considers Baumgarten's possible responses to Kant's pre-Critical objections to the proof of the PSR. The paper finds that Baumgarten possesses reasonable responses to all these objections. While the paper notes that in the absence of a (...) response to Kant's Critical discussion of the PSR, this result does not vindicate the principle, it shows how this discussion provides a deeper understanding of what, according to Baumgarten, the PSR really assumes and intends, and prepares the way for a more responsible discussion of Kant's Critical objections to Baumgarten's supposed proof.

Kant’ın 1781 tarihli Saf Aklın Eleştirisi adlı çalışmasına kadar geçen felsefî kariyeri, genel olarak literatürde, onun “eleştiri öncesi” dönemi olarak adlandırılır. Bu dönemin belirleyici unsuru, Kant’ın bir taraftan Newton fiziki diğer taraftan da Leibniz-Wolff metafiziki ile sürekli boğuşmasıdır. Bu süreç içerisinde Kant, aynı zamanda, hernekadar berrak ve keskin bir biçimde formüle edilmese de “eleştirel felsefe”ye doğru giden ilk açılımları da sunar. Bu çalışmanın amacı, Kant’ın sözü edilen düşünce dönemini mercek altına alarak onun “eleştiri öncesi” düşüncelerine dâir genel bir perspektif çizmektir. (...) *** Kant’s philosophical approach until the Critique of Pure Reason published at 1781 is generally designated in the history of philosophy as Kant’s “pre-critical” period. The determinative matter of this phase is a deep and continuous struggle of him with both Newtonian physics and metaphysics of Leibniz-Wolff school. Although he never clearly formulated those problems and solution proposals about the basic philosophical and metaphysical ideas of his “critical” period, there are some conceptual-patterns in his early writings that can be seen as pioneer ideas with respect to his posterior thoughts. The aim of this study is to present a general perspective about Kant’s “pre-critical” period by following his early texts. (shrink)

Spinoza ’s letter of June 2, 1674 to his friend Jarig Jelles addresses several distinct and important issues in Spinoza ’s philosophy. It explains briefly the core of Spinoza ’s disagreement with Hobbes’ political theory, develops his innovative understanding of numbers, and elaborates on Spinoza ’s refusal to describe God as one or single. Then, toward the end of the letter, Spinoza writes: With regard to the statement that figure is a negation and not anything positive, it is obvious that (...) matter in its totality, considered without limitation [indefinitè consideratam], can have no figure, and that figure applies only to finite and determinate bodies. For he who says that he apprehends a figure, thereby means to indicate simply this, that he apprehends a determinate thing and the manner of its determination. This determination therefore does not pertain to the thing in regard to its being [esse]; on the contrary, it is its non-being [non-esse]. So since figure is nothing but determination, and determination is negation [Quia ergo figura non aliud, quam determinatio, et determinatio negatio est], figure can be nothing other than negation, as has been said. Arguably, what is most notable about this letter is the fate of a single subordinate clause which appears in the last sentence of this passage: et determinatio negatio est. That clause was to be adopted by Hegel and transformed into the slogan of his own dialectical method: Omnis determinatio est negatio. Of further significance is the fact that, while Hegel does credit Spinoza with the discovery of this most fundamental insight, he believes Spinoza failed to appreciate the importance of his discovery. The issue of negation and the possibility of self-negation stand at the very center of the philosophical dialogue between the systems of Spinoza and Hegel, and in this paper I will attempt to provide a preliminary explication of this foundational debate between the two systems. In the first part of the paper I will argue that the “determination is negation” formula has been understood in at least three distinct senses among the German Idealists, and as a result many of the participants in the discussion of this formula were actually talking past each other. The clarification of the three distinct senses of the formula will lead, in the second part of the paper, to a more precise evaluation of the fundamental debate between Spinoza and Hegel regarding the possibility of self-negation. In this part I will evaluate the validity of each interpretation of the determination formula, and motivate the positions of the various participants in the debate. (shrink)

A crucial feature of Kant's critical-period writing on the sublime is its grounding in moral psychology. Whereas in the pre-critical writings, the sublime is viewed as an inherently exhausting state of mind, in the critical-period writings it is presented as one that gains strength the more it is sustained. I account for this in terms of Kantian moral psychology, and explain that, for Kant, sound moral disposition is conceived as a sublime state of mind.

Kant's Observations of 1764 and Remarks of 1764–5 document a crucial turning point in his life and thought. Both reveal the growing importance for him of ethics, anthropology and politics, but with an important difference. The Observations attempts to observe human nature directly. The Remarks, by contrast, reveals a revolution in Kant's thinking, largely inspired by Rousseau, who 'turned him around' by disclosing to Kant the idea of a 'state of freedom' as a touchstone for his thinking. This and related (...) thoughts anticipate such famous later doctrines as the categorical imperative. This collection of essays by leading Kant scholars illuminates the many and varied topics within these two rich works, including the emerging relations between theory and practice, ethics and anthropology, men and women, philosophy, history and the 'rights of man'.

: Kant’s 1763 essay, Attempt to Introduce the Concept of Negative Magnitudes into Philosophy, is one of the least discussed of all his pre-critical writings. When it is referred to, it is usually just to note a few passages that anticipate Kant’s later, Critical philosophy. I argue that instead of understanding these early anticipations of the Critical philosophy as separable from Kant’s discussion of negative magnitudes, we should take their origin in Kant’s investigation of negative magnitudes to be of central (...) importance, since it can help us to understand aspects of Kant’s Critical view of cognition where negative magnitudes still play a role. I argue that negative magnitudes suggest to Kant a kind of cognitive activity that is neither the spontaneity of discursive thought not the receptivity of the senses. Rather it is an “effort” of the mind, of which we are conscious through a feeling. I show that Kant’s early views about negative magnitudes are retained in his Critical philosophy. (shrink)

Cet article cherche à reconstituer la thèse de Christian Wolff sur l’évidence (Deutlichkeit) des principes métaphysiques, dans un article de 1729 sur les « Notions directrices et le véritable usage de la première science », qui offre une référence centrale (et méconnue aujourd’hui) aux répondants du concours de 1762-1763, dont Kant. Wolff affirme en effet que la métaphysique est susceptible d’une certitude égale voire supérieure à celle des mathématiques et qu’elle diffuse cette certitude à travers toutes les autres disciplines ; (...) c’est cette thèse forte qu’il s’agira précisément de questionner en 1763. Une lecture plus attentive de l’article de Wolff permet d’en dégager certaines prémisses. La thèse de Wolff sur la certitude mathématique de la métaphysique est fondée sur un renversement de l’ordre de priorité entre métaphysique (ontologie) et mathématiques. Selon Wolff qui, dans son débat avec les mathématiques, s’appuie notamment sur la géométrie euclidienne, ce sont des notions métaphysiques qui fondent la validité des règles mathématiques et logiques. Des notions comme « identité », « chose », « possibilité », etc., possèdent en effet un statut « directeur » ou méthodique, dirigeant l’esprit sur le chemin de la connaissance et, sous une forme systématisée, composent une ontologie moderne et « architectonique ». La restitution de ce cadre permet de mieux voir la continuité méthodologique entre Wolff et Kant. En effet, même si Kant conteste la validité de quelques-uns de ces concepts, les modalités de leur systématisation et l’équation entre science architectonique et ontologie, sa Recherche sur l’évidence des principes s’inscrit à l’intérieur du programme, esquissé par Wolff, de la fondation d’une métaphysique architectonique contenant un tableau de concepts directeurs. De ce point de vue, Kant s’avère plus tributaire de la méthode wolffienne qu’il n’est supposé communément, et leur débat gagne en profondeur. (shrink)

The goal of this paper is to analyze the beginning of the concept of dogmatism attributed by Kant to the Enlightenment, particularly that one that begins with Leibniz. The idea is that we can find many elements, already presented in the pre-critical period, that make Kant an original thinker even before the appearance of the Critique of Pure Reason. Analyzing the comments made by Kant to Mendelssohn and Eberhard, it is revealed here a route of the kantian thought, that tries (...) to follow closely the indications of the very Kant, in the sense that Kant himself mentions a shift not only in the history of pure reason, but also in his own thought, that is: there was a dogmatic period, another skeptical and finally the critical one. Based on this, it is possible to contest the current notion that there was this skeptical period in the kantian thought occasioned by the reading of Hume’s works. (shrink)
