This chapter analyzes several key themes in Kant’s views about modality. We begin with the pre-critical Only Possible Argument in Support of a Demonstration of the Existence of God, in which Kant distinguishes between formal and material elements of possibility, claims that all possibility requires an actual ground, and argues for the existence of a single necessary being. We then briefly consider how Kant’s views change in his mature period, especially concerning the role of form and thought in defining modality. (...) Kant’s mature views, however, present two difficult interpretive puzzles. The first puzzle concerns whether Kant has a generally reductive view of modality. While Kant’s views on logical modality, the role of actuality in grounding possibility, and the relation of modality to cognition all suggest reduction, we argue that the categorial status of modal concepts and the difficulty in even identifying amodal grounds for modal facts all suggest a non-reductive view. The second puzzle concerns whether Kant accepts modal facts or properties at the noumenal level. While Kant’s appeal to noumenal necessary connections, the contingency of noumenal willing, and the idea of a necessary noumenal being suggest that he endorses noumenal modality, his claims that modal concepts express only relations to the faculty of cognition and his claim that modal concepts arise from our distinctive psychological structures, we argue, suggest that he rejects noumenal modality. We conclude by considering potential solutions to these puzzles. (shrink)

A historical and philosophical reassessment of the impact of Aristotle and early-modern Aristotelianism on the development of Kant’s transcendental philosophy. Kant and Aristotle reassesses the prevailing understanding of Kant as an anti-Aristotelian philosopher. Taking epistemology, logic, and methodology to be the key disciplines through which Kant’s transcendental philosophy stood as an independent form of philosophy, Marco Sgarbi shows that Kant drew important elements of his logic and metaphysical doctrines from Aristotelian ideas that were absent in other philosophical traditions, such as (...) the distinction of matter and form of knowledge, the division of transcendental logic into analytic and dialectic, the theory of categories and schema, and the methodological issues of the architectonic. Drawing from unpublished documents including lectures, catalogues, academic programs, and the Aristotelian-Scholastic handbooks that were officially adopted at Königsberg University where Kant taught, Sgarbi further demonstrates the historical and philosophical importance of Aristotle and Aristotelianism to these disciplines from the late sixteenth century to the first half of the eighteenth century.

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)

In this paper I argue that Kant’s pre-critical ontology, though generally dismissed by environmental philosophers, provides ecological lessons by way of its metaphysical affinities with environmental philosophy. First, I reference where environmental philosophy tends to place Kant and highlight his relative marginalization. This marginalization makes sense given focus on his critical works. I then outline Kant’s pre-critical ontological framework and characterize the ways in which it is ecological. Finally, I conclude with some ecological reflections on the pre-critical philosophy and its (...) possible relevance for contemporary environmental issues. (shrink)

Kant’s theory of biology in the Critique of the Power of Judgment may be rejected as obsolete and attacked from two opposite perspectives. In light of recent advances in biology one can claim contra Kant, on the one hand, that biological phenomena, which Kant held could only be explicated with the help of teleological principles, can in fact be explained in an entirely mechanical manner, or on the other, that despite the irreducibility of biology to physico-mechanical explanations, it is nonetheless (...) proper science. I argue in response that Kant’s analysis of organisms is by no means obsolete. It reveals biology’s uniqueness in much the same way as several current theorists do. It brings to the fore the unique purposive characteristics of living phenomena, which are encapsulated in Kant’s concept of “natural end” and which must be explicated in natural terms in order for biology to become a science. I maintain that Kant’s reluctance to consider biology proper science is not a consequence of his critical philosophy but rather of his inability to complete this task. Kant lacked an appropriate theoretical framework, such as provided later by modern biology, which would enable the integration of the unique features of biology in an empirical system. Nevertheless, as I show in this paper, the conceptual problems with which Kant struggled attest more to the relevance and depth of his insights than to the shortcomings of his view. His contribution to the biological thought consists in insisting on an empirical approach to biology and in providing the essential philosophical underpinning of the autonomous status of biology.

This article begins with a brief survey of Kant’s pre-Critical and Critical approaches to theodicy. I maintain that his theodical response of moral faith during the Critical period appears to be a dispassionate version of what Leibniz called Fatum Christianum. Moral rationality establishes the existence and goodness of God and translates into an endless and unwavering commitment to following the moral law. I then argue that Religion within the Boundaries of Mere Reason offers a revision of Kant’s 1791 conception of (...) “authentic theodicy.” Kant comes to recognize that the ends of morality and virtue, as well as the action needed to respond to the noumenal evil at the heart of humanity, outstrip the “religion of good life conduct.” This leads Kant to argue in favor of a new form of moral life embedded in a religious community and based on the love of God and of one’s fellow humans. Such a life is rooted in the incorporation of a holy principle in our noumenal selves that he terms “divine blessedness.”. (shrink)

This article aims to make further progress in revising the standard account of Wolff’s philosophy as a popularisation and systematisation of Leibniz’s doctrines. It focuses on the topic of the communication among substances and the metaphysics of simples and activity underlying it. It is argued that Wolff does not accept the pre-established harmony in its orthodox Leibnizian version. The article explains Wolff’s departure from Leibniz’s PEH as stemming from his rejection of Leibniz’s construal of the activity of every simple as (...) representational power and of the metaphysics of unity and activity in which that construal is rooted.

Para el autor de este artículo, el rechazo kantiano de la identificación de su concepto de a priori con la noción leibniciana de lo innato solo puede comprenderse de manera clara y precisa, si recurrimos a la concepción kantiana de la epigénesis como modelo epistemológico; es decir, si consideramos las facultades cognitivas como fuerzas formativas que se componen con otras fuerzas de la naturaleza para hacer posible la adquisición originaria de intuiciones y conceptos a priori.

This paper explores the scientific sources behind Kant’s early dynamic theory of matter in 1755, with a focus on two main Kant’s writings: Universal Natural History and Theory of the Heavens and On Fire. The year 1755 has often been portrayed by Kantian scholars as a turning point in the intellectual career of the young Kant, with his much debated conversion to Newton. Via a careful analysis of some salient themes in the two aforementioned works, and a reconstruction of the (...) scientific sources behind them, this paper shows Kant’s debt to an often overlooked scientific tradition, i.e. speculative Newtonian experimentalism. The paper argues that more than the Principia, it was the speculative experimentalism that goes from Newton’s Opticks to Herman Boerhaave’s Elementa chemiae via Stephen Hales’ Vegetable Staticks that played a central role in the elaboration of Kant’s early dynamic theory of matter in 1755.

This paper examines Du Châtelet’s and Kant’s responses to the famous vis viva controversy – Du Châtelet in her Institutions Physiques (1742) and Kant in his debut, the Thoughts on the True Estimation of Living Forces (1746–49). The Institutions was not only a highly influential contribution to the vis viva controversy, but also a pioneering attempt to integrate Leibnizian metaphysics and Newtonian physics. The young Kant’s evident knowledge of this work has led some to speculate about his indebtedness to her (...) philosophy. My study corrects such speculations as well as misunderstandings of the Living Forces. This corrective result has implications for how to investigate Kant’s relation to the ever-evolving landscape of Leibniz exegeses. (shrink)

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.

Estableciendo las bases de su primera síntesis precrítica, Kant presenta en la Nova dilucidatio los principios de sucesión y de coexistencia, que, además de hacer posible un conocimiento metafísico de la naturaleza, pretendían ser útiles para la ciencia natural. Ambos son derivados del principio de razón determinante, formulado en el marco de una crítica a Wolff. Estos principios establecen que el mundo está constituido por la totalidad de las substancias conformada por una red dinámica de interconexiones causales, cuyo fundamento último (...) es el esquema relacional con el que el intelecto divino concibe al mundo.

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.

The subject of this article is Herder’s unique conception of the soul-body relationship and its divergence from and dependence on Leibniz. Herder’s theory is premised on a rejection of the windowlessness of monads in two important respects: interaction between material bodies (as gleaned from Crusius and Kant) and interaction between the soul and body. Herder’s theory depends on Leibniz insofar as it agrees with the intimate connection Leibniz posits between the soul and the body, as his epistemology demonstrates, with, however, (...) the significant modification that the connection is real. Herder transforms the Leibnizian rehabilitation and use of substantial forms to develop a double-conception of the human soul as both thinking substance and substantial form: the soul, qua thinking substance, needs a body through whose senses it can interact with, and acquire knowledge of, the external world; the soul, qua substantial form, constructs itself this material body by harnessing the forces of attraction and repulsion. Herder’s theory provides an alternative to other contemporary accounts of the soul-body relationship, especially Kant’s, which start from the problem of relating two distinct substances. His unique and original reconciliation of the modern dichotomy of spirit and matter, via his connecting of Leibniz’s realms of final and efficient causes, is of great significance for the rise of German Idealism.

In this paper, I argue that Kant adopted, throughout his career, a position that is much more akin to classical accounts of epigenesis, although he does reject the more radical forms of epigenesis proposed in his own time, and does make use of preformationist sounding terms. I argue that this is because Kant thinks of what is pre-formed as a species, not an individual or a part of an individual; has no qualm with the idea of a specific, teleological principle (...) or force underlying generation, and conceives of germs and predispositions as specific constraints on such a principle or force. Neither of these conceptions of what is “preformed”, I argue, is in strict opposition to classical epigenesis. I further suggest that Kant’s lingering use of preformationist terminology is due to his belief that this is required to account for the specificity of the specific generative force; his resistance towards the unrestricted plasticity of the generative force in radical epigenesis, which violates species-fixism; and his insistence on the internal, organic basis of developmental plasticity and variation within species. I conclude by suggesting that this terminological and interpretative peculiarity is partly due to a larger shift in the natural philosophical concerns surrounding the debate on epigenesis and preformation. Specifically, it is a sign that the original reasons for resisting epigenesis, namely its use of specific, teleological principles and its commitment to the natural production of biological structure, became less of a concern, whereas unrestricted plasticity and its undermining of fixism became a real issue, thereby also becoming the focal point of the debate.

The question of the dimensionality of space has informed the development of physics since the beginning of the twentieth century in the quest for a unified picture of quantum processes and gravitation. Scientists have worked within various approaches to explain why the universe appears to have a certain number of spatial dimensions. The question of why space has three dimensions has a genuinely philosophical nature that can be shaped as a problem of justifying a contingent necessity of the world. In (...) contrast to explanations of three-dimensionality based on anthropic arguments, we support the search for a theory that provides a justification for the dimensionality of space based on a combination of deductive and inductive reasoning applied to science. In doing so, we argue that Kant correctly approached the question in “Thoughts on the true estimation of living forces” by connecting space dimensionality and the inverse square law. In expounding the strategy of Kant’s argument, we describe the main features of a general Kantian explanation of the dimensionality of space and discuss them with respect to current accounts of explanation in the philosophy of science, such as inference to the best explanation and the deductive-nomological model.

Kant's speculative theistic proof rests on a distinction between “logical” and “real” modality that he developed very early in the pre-critical period. The only way to explain facts about real possibility, according to Kant, is to appeal to the properties of a unique, necessary, and “most real” being. Here I reconstruct the proof in its historical context, focusing on the role played by the theory of modality both in motivating the argument (in the pre-critical period) and, ultimately, in undoing it (...) as a source of knowledge of God's existence (in the critical period). Along the way I examine Kant's version of the now-popular “actualist” thesis that facts about what is possible must be explained by facts about what is actual. I conclude by discussing why the critical Kant claims both that there are rational grounds for accepting the conclusion of his theistic proof, and that such acceptance can not count as knowledge. This is important, I argue, because the same considerations ultimately motivate his prohibition on knowledge of things-in-themselves generally. -/- . (shrink)

In the first part of the paper I reconstruct Kant’s proof of the existence of a ‘most real being’ while also highlighting the theory of modality that motivates Kant’s departure from Leibniz’s version of the proof. I go on to argue that it is precisely this departure that makes the being that falls out of the pre-critical proof look more like Spinoza’s extended natura naturans than an independent, personal creator-God. In the critical period, Kant seems to think that transcendental idealism (...) allows him to avoid this conclusion, but in the last section of the paper I argue that there is still one important version of the Spinozistic threat that remains. -/- .

I _Sogni di un visionario chiariti con sogni della metafisica_ del 1766 sono sempre stati visti come un'opera unica all'interno dell'intera produzione filosofica di Kant. Se tradizionalmente si è visto in questo scritto il momento di massima vicinanza a Hume e quindi di massimo scetticismo antimetafisico da parte di Kant, negli ultimi tre decenni non sono mancate letture che hanno visto in esso non soltanto una continuità con la metafisica kantiana precedente ma anche un interesse vero e genuino da parte (...) di Kant per le teorie del mistico svedese Emanuel Swedenborg (1688-1772). Tuttavia, nessuna di queste letture ha riservato un'attezione adeguata al terzo capitolo della prima parte dei _Sogni_, nel quale Kant prende in esame i "sognatori della ragione" e i "sognatori della sensazione". Si tratta di una sezione del testo particolarmente interessante perché stabilisce quello stesso confronto fra errore metafisico ed errore empirico che Kant stabilisce quindici anni più tardi nella C_ritica della ragion pura_. L'esame del confronto fra questi due luoghi testuali permette dunque di vedere come si è evoluta la concezione kantiana dell'errore dal 1766 al 1781, e permette conseguentemente di capire in cosa la teoria dell'errore presente nella _Critica _si distingua essenzialmente da quella presente nei _Sogni_.

In the Critique of Pure Reason, following his elucidation of the ‘postulates’ of possibility, actuality, and necessity, Kant makes a series of puzzling remarks. He seems to deny the somewhat metaphysically intuitive contention that the extension of possibility is greater than that of actuality, which, in turn, is greater than that of necessity. Further, he states that the actual adds nothing to the possible. This leads to the view, fairly common in the literature, that Kant holds that all modal categories, (...) in their empirical applications, are coextensive. I diverge from the common view. First, Kant is not committed to the coextensiveness thesis, understood as above. Instead, he espouses a weaker, epistemological version of the coextensiveness thesis, namely that what we can assert to be really possible is coextensive with what we cognize to be actual. Second, Kant's remarks are not intended to introduce a positive ontological thesis about the extensions of modal categories. Rather, he means to criticize a certain conception of modalities that was prevalent among his rationalist predecessors, i.e., the conception of modalities as various determinations that enter the intensions of concepts of things.

Nei Pensieri sulla vera valutazione delle forze vive Kant stabilisce il concetto di “mondo” per mezzo di una definizione wolffiana. Nonostante questa recezione, Kant non condivide con Wolff e i wolffiani principi fondanti della cosmologia in quanto sapere metafisico. Il contributo chiarisce come Kant metta in evidenza l'inadeguatezza della definizione wolffiana rispetto a problemi basilari della cosmologia, come la possibilità di dimostrare l'unicità del mondo e l'unità dell'universo. A differenza di precedenti interpretazioni, il contributo sostiene che Kant prova a ovviare (...) a questa inadeguatezza proponendo un riesame del concetto di luogo e una nuova concezione delle relazioni esterne della sostanza. In riferimento a questo tema il contributo offre una nuova interpretazione delle riflessioni di Kant sulla dimensionalità dell'estensione mostrandone la rilevanza per comprendere la sua prima concezione dello spazio.

The contribution analyses the third part of the "Allgemeine Naturgeschichte", written by Kant in 1755, and focuses in particular on the ontological nexus that relate the activity of the soul to the material quality and to the morphology of the organic body. In the course of the analysis, the presence of two argumentative logics of Kant’s discourse will be highlighted. For the first one, the body is a limitation of the spirit, which would fully develop its cognitive faculties if it (...) were not connected to any matter. For the second one, on the contrary, the connection with the body becomes a necessary condition for the spirit to be given the faculty to exercise its own power of thought. (shrink)

The role and place of transcendental psychology in Kant's Critique of Pure Reason has been a source of some contention. This work presents a detailed argument for restoring transcendental psychology to a central place in the interpretation of Kant's Analytic, in the process providing a detailed response to more "austere" analytic readings.

Este trabajo tiene como objetivo contribuir, desde el punto de vista de la Kantforschung y empleando los referentes de la Quellengeschichte, al conocimiento de las actitudes del joven Kant ante la metafísica tal y como están expresadas en su más temprana obra sobre las ‘fuerzas vivas’ de 1747-1749. La amplia gama de doctrinas metafísicas que envolvió la formación universitaria de Kant tuvo como su principal característica el pluralismo: aunque podemos distinguir algunas tradiciones filosóficas diferentes entre sí como el aristotelismo neoescolástico, (...) el eclecticismo pietista y el racionalismo wolffiano, durante los años en los que Kant fue un estudiante de la Universidad de Königsberg —e incluso algunos años antes—, contra la creencia tradicional, ninguna orientación doctrinal tuvo predominio alguno. Esta situación plural generó un ambiente intelectual peculiar, diferente al de las otras universidades alemanas, el cual tuvo una relevante influencia sobre las primeras actitudes intelectuales de Kant ante la metafísica.

This thesis aims to throw an illuminating light on the as yet neglected concept of nothing in Kant’s system, a concept which is taken into consideration, by Kant, in accordance with the guiding thread of the categories of the understanding. My main argument is that Kant has a fourfold division of nothing and each has a transcendental function in his system. This function is basically a limiting one; setting up negative determinations without which Kant’s system would have never been constituted (...) as it is now. It is shown in the thesis that the concept of nothing is divided basically into four: first, nothing as ens rationis that limits and thereby protects knowledge, secondly nothing as nihil privativum that defines the boundaries of phenomenal reality, thirdly nothing as ens imaginarium that makes possible the unity of experience and finally, nothing as nihil negativum that draws the lines of logical thinking. All make, in the last resort and by being the concepts of the opposite, experience possible. The thesis consists of four chapters. The first chapter is an exposition of all four divisions of nothing, the second is the display specifically of the concepts of ens rationis and nihil negativum, and the third is of the concepts of ens imaginarium and nihil privativum. The auxiliary argument of the thesis is that while Hegel makes a strong charge of externality against and thereby severely criticizes the Kantian concept of the thing-in-itself, - the concept of which I propose to be contained under the concept of ens rationis- Kant has equally convincing arguments against such a charge. This is the topic of the fourth and final chapter which has an implicit aim of creating the image of a powerful critical Hegel but on the other hand an equally enduring and war-like Kant. Kant is presented as a philosopher who has powerful responses to institute a balance between himself and his opponent. When Kant’s differing concepts of nothing are taken into account, Hegel’s attack of externality, it is maintained, appears not to have taken into account the full measure of the resources of the Kantian position. Even when it is said that the attack is against one specific concept of the thing-in-itself alone, Kant still seems to have enough resources for toleration and defence indeed. (shrink)

The subject of this chapter is the complex and confusing course of the discussion of cause and teleology before and during the period of Mill and Comte, and its aftermath up to the early years of the twentieth century in the thinking of several of the major founding figures of disciplinary social science. The discussion focused on the problem of the sufficiency of causal explanations, and particularly the question of whether some particular fact could be explained without appeal to purpose. (...) In response to such questions, the defenders of the new conception attempted to replace older terminology with new (“function” for “purpose,” for example), sometimes muddling the issues, sometimes turning them into terminological disputes, and sometimes making the different positions difficult to distinguish. The problem of methodological unity in the social sciences is rooted in the discussions of the time. (shrink)

بر اساس اندیشۀ کانت در دوران نقدی، ایدۀ خدا به عنوان یکی از ایده‌های استعلایی عقل محض مطرح است که عقل نظری با توجه به محدودیت‌هایش نمی‌تواند له یا علیه آن برهانی اقامه کند. اما در دوران پیشانقدی، کانت رسالۀ مستقلی با عنوان «تنها حجت ممکن در تأیید برهان وجود خدا» تألیف کرده و در آن سعی کرده است تا وجود خدا را از طریق براهین عقل نظری اثبات کند. اهمیت این رساله در این است که از یک سو بر (...) خلاف اندیشۀ دوران نقدی برای عقل نظری شأن برهان‌آوری در اثبات وجود خدا قائل می‌شود و از سوی دیگر، بر خلاف سنت ولفی‌ـ‌لایبنیتسی، به جای برهان جهان‌شناختی، برهان طبیعی‌ـ‌الهیاتی را مطرح می‌کند. به علاوه، با محور قرار دادن مفهوم امکان در تقریر برهان وجودی، با تقریر فیلسوفان پیشین - علی‌الخصوص دکارت - مخالفت می‌کند و تقریر جدیدی از آن ارائه می‌دهد. در این مقاله ابتدا مسیر اختصاصی استدلال کانت مبنی بر اثبات وجود خدا را بر مبنای رسالۀ مذکور توضیح داده‌ایم و در مرحلۀ دوم، مستند به برخی پژوهش‌های جدیدتر، نشان داده‌ایم که تعارض بین عنوان کتاب و محتوای آن ، که برخی دیگر کانت‌شناسان را به این گمان انداخته که کانت متهافت سخن گفته است، یک تعارض بدوی و برآمده از ترجمۀ خطای اصطلاح Beweisgrund از آلمانی به انگلیسی است.
