According to strong metaphysical readings of Kant, Kant believes there are noumenal substances and causes. Proponents of these readings have shown that these readings can be reconciled with Kant’s claims about the limitations of human cognition. An important new challenge to such readings, however, has been proposed by Markus Kohl, focusing on Kant’s occasional statements about the divine or intuitive intellect. According to Kohl, how an intuitive intellect represents is a decisive measure for how noumena are for Kant, but an (...) intuitive intellect would not represent using metaphysical categories like those of substance and causation. I argue that Kohl’s argument does not succeed, since it overlooks the possibility that the intuitive intellect only indirectly represents certain noumenal facts. In addition, in response to a secondary argument Kohl suggests, I argue that Kant’s apparently anti-metaphysical statements about the content of the categories can be read as merely describing the constitution of the categories, instead of what they represent. Thus, while Kohl advances the debate by raising an under-appreciated question, his argument against the strong metaphysical reading is unsound. (shrink)

It is well known that Kant claims that causal judgments, including judgments about forces, must have an a priori basis. It is less well known that Kant claims that we can perceive the repulsive force of bodies through the sense of touch. Together, these claims present an interpretive puzzle, since they appear to commit Kant to both affirming and denying that we can have perceptions of force. My first aim is to show that both sides of the puzzle have deep (...) roots in Kant's philosophy. My second aim is to present three potential solutions to the puzzle and show that each faces problems. (shrink)

In theCritique of Pure Reason,Kant argues for two principles that concern magnitudes. The first is the principle that ‘All intuitions are extensive magnitudes,’ which appears in the Axioms of Intuition (B202); the second is the principle that ‘In all appearances the real, which is an object of sensation, has an intensive magnitude, that is, a degree,’ which appears in the Anticipations of Perception (B207). A circle drawn in geometry and the space occupied by an object such as a book are (...) paradigm examples of extensive magnitudes, while the intensity of a light is a paradigm example of an intensive magnitude. These principles justify and explain the possibility of applying mathematics to objects of experience. The Axioms principle also explains the possibility of any mathematical cognition at all.

In his applied moral philosophy, Kant formulates the parents’ duty to make their child happy. I argue that, for Kant, this duty is an ad hoc attempt at compensating for the parental guilt of having brought a person into the condition of existence – and hence also having created her need for happiness – on their own initiative. I argue that Kant’s considerations regarding parental duties and human reproduction in general imply arguments for an ethically justified anti-natalism, but that this (...) position is abolished in his teleology for meta-ethical reasons.

The motives of philosophers tend to be personal. Philosophy has mattered politically as part of continuing political debates. Its effects on politics, religion and the development of the sciences have been evident. Philosophy has been supposed to have special educational value, from its contents or from the benefits of its methods and arguments. This is doubtful. Rather, philosophy matters because its concerns matter. How much philosophy matters, or should matter, may be a question of local taste.

It is often maintained that one insight of Kant's Critical philosophy is its recognition of the need to distinguish accounts of knowledge acquisition from knowledge justification. In particular, it is claimed that Kant held that the detailing of a concept's acquisition conditions is insufficient to determine its legitimacy. I argue that this is not the case at least with regard to geometrical concepts. Considered in the light of his pre-Critical writings on the mathematical method, construction in the Critique can be (...) seen to be a form of concept acquisition, one that is related to the modal phenomenology of geometrical judgement. (shrink)

I advance a novel interpretation of Kant's argument that our original representation of space must be intuitive, according to which the intuitive status of spatial representation is secured by its infinitary structure. I defend a conception of intuitive representation as what must be given to the mind in order to be thought at all. Discursive representation, as modelled on the specific division of a highest genus into species, cannot account for infinite complexity. Because we represent space as infinitely complex, the (...) spatial manifold cannot be generated discursively and must therefore be given to the mind, i.e. represented in intuition. (shrink)

Shedding new light on Kant’s use of the term ‘transcendental’ in the Critique of Pure Reason, this article aims to determine the elements that Kant’s transcendental philosophy has in common with Wolffian ontology as well as the respects in which Kant turns against Wolff. On this basis I argue that Wolff’s, Kant’s and Hegel’s conceptions of metaphysics – qua first philosophy – have a deeper affinity than is commonly assumed. Bracketing the issue of Kant’s alleged subjectivism, I challenge the opposition (...) between metaphysical and non-metaphysical readings of Hegel’s Science of Logic. One the one hand, I argue that Hegel was more deeply indebted to Kant than he generally admits. On the other hand, I hold that this debt concerns Kant’s conception of metaphysics rather than his alleged subjectivism. (shrink)

This essay tries to show that there exist several passages where Kierkegaard (and his pseudonyms) sketches an argument for the existence of God and immortality that is remarkably similar to Kant's so-called moral argument for the existence of God and immortality. In particular, Kierkegaard appears to follow Kant's moral argument both when it comes to the form and content of the argument as well as some of its terminology. The essay concludes that several passages in Kierkegaard overlap significantly with Kant's (...) moral argument, although Kierkegaard ultimately favors revealed faith over natural theology in general and Kant's moral faith in particular. Whereas Kant uses the moral argument to postulate the existence of God and immortality, Kierkegaard mainly uses it as a reductio ad absurdum of non-religious thinking. (shrink)

Kant’s account of the freedom gained through virtue builds on the Socratic tradition. On the Socratic view, when morality is our end, nothing can hinder us from attaining satisfaction: we are self-sufficient and free since moral goodness is (as Kant says) “created by us, hence is in our power.” But when our end is the fulfillment of sensible desires, our satisfaction requires luck as well as the cooperation of others. For Kant, this means that happiness requires that we get other (...) people to work for our ends; and this requires, in turn, that we gain control over the things other people value so as to have influence over them. If this plan for happiness is not subordinated to morality, then what is most valuable to us will be precisely what others value. This is the root of the “passions” that make us evil and make us slaves whose satisfaction depends on others. But, significantly, this dependence is a moral slavery and hence does not signal a loss, or even diminishment of the kind of freedom required for moral responsibility. (shrink)

Logic is usually thought to concern itself only with features that sentences and arguments possess in virtue of their logical structures or forms. The logical form of a sentence or argument is determined by its syntactic or semantic structure and by the placement of certain expressions called “logical constants.”[1] Thus, for example, the sentences Every boy loves some girl. and Some boy loves every girl. are thought to differ in logical form, even though they share a common syntactic and semantic (...) structure, because they differ in the placement of the logical constants “every” and “some”. By contrast, the sentences Every girl loves some boy. and Every boy loves some girl. are thought to have the same logical form, because “girl” and “boy” are not logical constants. Thus, in order to settle questions about logical form, and ultimately about which arguments are logically valid and which sentences logically true, we must distinguish the “logical constants” of a language from its nonlogical expressions. (shrink)

Officially, for Kant, judgments are analytic iff the predicate is "contained in" the subject. I defend the containment definition against the common charge of obscurity, and argue that arithmetic cannot be analytic, in the resulting sense. My account deploys two traditional logical notions: logical division and concept hierarchies. Division separates a genus concept into exclusive, exhaustive species. Repeated divisions generate a hierarchy, in which lower species are derived from their genus, by adding differentia(e). Hierarchies afford a straightforward sense of containment: (...) genera are contained in the species formed from them. Kant's thesis then amounts to the claim that no concept hierarchy conforming to division rules can express truths like '7+5=12.' Kant is correct. Operation concepts ( ) bear two relations to number concepts: and are inputs, is output. To capture both relations, hierarchies must posit overlaps between concepts that violate the exclusion rule. Thus, such truths are synthetic. (shrink)

I show how Sir William Rowan Hamilton’s philosophical commitments led him to a causal interpretation of classical mechanics. I argue that Hamilton’s metaphysics of causation was injected into his dynamics by way of a causal interpretation of force. I then detail how forces are indispensable to both Hamilton’s formulation of classical mechanics and what we now call Hamiltonian mechanics (i.e., the modern formulation). On this point, my efforts primarily consist of showing that the contemporary orthodox interpretation of potential energy is (...) the interpretation found in Hamilton’s work. Hamilton called the potential energy function the “force-function” because he believed that it represents forces at work in the world. Various non-historical arguments for this orthodox interpretation of potential energy are provided, and matters are concluded by showing that in classical Hamiltonian mechanics, facts about the potential energies of systems are grounded in facts about forces. Thus, if one can tolerate the view that forces are causes of motion, then Hamilton provides one with a road map for transporting causation into one of the most mathematically sophisticated formulations of classical mechanics, viz., Hamiltonian mechanics.

Kant typically is not identified with the tradition of virtue epistemology. Although he may not be a virtue epistemologist in a strict sense, I suggest that intellectual virtues and vices play a key role in his epistemology. Specifically, Kant identifies a serious intellectual vice that threatens to undermine reason, namely enthusiasm (Schwärmerei). Enthusiasts become so enamored with their own thinking that they refuse to subject reason to self-critique. The particular danger of enthusiasm is that reason colludes in its own destruction: (...) enthusiasm occurs when self-conceit and reason’s desire to transcend its boundaries mutually reinforce each other. I conclude by sketching an account of Kantian intellectual virtue that is consistent with Kantian moral virtue. (shrink)

In the ‘Appendix to the Transcendental Dialectic’ of the Critique of Pure Reason, Kant contends that the idea of God has a positive regulative role in the systematization of empirical knowledge. But why is this regulative role assigned to this specific idea? Kant’s account is rather opaque and this question has also not received much attention in the literature. In this paper I argue that an adequate understanding of the regulative role of the idea of God depends on the specific (...) metaphysical content Kant attributes to it in the Critique and other writings. I show that neither a heuristic principle of conceptual systematicity, nor conceiving God as a hypothesis of an intelligent designer, can satisfy the demands of reason to make the unity and necessity of the laws of nature intelligible. Regarding the positive account about the metaphysical content of the idea of God, I support my argument by referring to Kant’s pre-critical discussion of the usefulness of the conception of God for the project of science, and by expounding Kant’s critical account of the necessity of the laws of nature. Thus my account sheds light on the continuity of Kant’s conception of God and his appropriation of his own rationalistic metaphysics. (shrink)

Since his Metaphysische Anfangsgründe der Naturwissenschaft was first published in 1786, controversy has surrounded Immanuel Kant’s conception of matter. In particular, the justification for both his dynamical theory of matter and the related dismissal of mechanical philosophy are obscure. In this paper, I address these longstanding issues and establish that Kant’s dynamism rests upon Leibnizian, metaphysical commitments held by Kant from his early pre-Critical texts on natural philosophy to his major critical works. I demonstrate that, throughout his corpus and inspired (...) by Leibniz, Kant endorses the a priori law of continuity of alteration as a truth of metaphysics, according to which all alterations in experience must occur gradually through all intervening degrees. The principle thus legislates against mechanical philosophy’s absolutely impenetrable atoms, as they would would involve instantaneous changes of velocity in impact. This reveals the metaphysical incoherencies in mechanical philosophy and leaves Kant’s own dynamical theory of matter, grounded on material forces, as the only viable approach to physical explanation. Subsequently, I demonstrate that Kant nevertheless made conceptual space in his system for the theoretical consideration of mechanical explanations, which makes manifest one of the positive roles that the faculty of reason can play with respect to natural science. (shrink)

Little extended attention has been given to Kant's notion of self-conceit, though it appears throughout his theoretical and practical philosophy. Authors who discuss self-conceit often describe it as a kind of imperiousness or arrogance in which the conceited agent seeks to impose selfish principles upon others, or sees others as worthless. I argue that these features of self-conceit are symptoms of a deeper and more thoroughgoing failure. Self-conceit is best described as the tendency to insist upon one to oneself or (...) to others s will or inclinations upon others, and more centrally the tendency to reconstruct evidence and rationalize so that one may be convinced of one’s own virtue. While the conceited agent may ultimately impose her judgement upon others, she does so in order to preserve her delusion of virtue. (shrink)

Kant's response to scepticism in the Critique of Pure Reason is complex and remarkably nuanced, although it is rarely recognized as such. In this paper, I argue that recent attempts to flesh out the details of this response by Paul Guyer and Michael Forster do not go far enough. Although they are right to draw a distinction between Humean and Pyrrhonian scepticism and locate Kant's response to the latter in the Transcendental Dialectic, their accounts fail to capture two important aspects (...) of this response. The first is that Kant's response to Pyrrhonian scepticism is also a response to Hume. The second is that aspects of this response are decidedly positive. In particular, I argue (1) that Kant believed Hume's scepticism manifested important elements of Pyrrhonian scepticism and (2) that both Pyrrhonian scepticism and Hume had a significant positive influence on the development of the Transcendental Dialectic.

There are perceptual states whose representational content cannot even in principle be conceptual. If that claim is true, then at least some perceptual states have content whose semantic structure and psychological function are essentially distinct from the structure and function of conceptual content. Furthermore the intrinsically “orientable” spatial character of essentially non-conceptual content entails not only that all perceptual states contain non-conceptual content in this essentially distinct sense, but also that consciousness goes all the way down into so-called unconscious or (...) subpersonal mental states. Both my argument for the existence of essentially non-conceptual content and my theory of its structure and function have a Kantian provenance. (shrink)

In his lectures on Logic and Metaphysics, Kant distinguishes between logical and real essences. While the former is related to concepts and is knowable, the latter is related to things and is unknowable. In this paper, I argue that the unknowability is explained by the modal characteristic of real essences as a necessitating ground on which a priori knowledge is impossible. I also show how this claim is related to the unknowable necessity of particular laws of nature. Since laws of (...) nature are conceived as grounded in real essences, the unknowability of the latter is equivalent to Kant's other claim that there can be no knowledge of the necessity of particular laws of nature. Necessity can only be known a priori, and therefore, the necessity of particular laws is only assumed and conceived as grounded in something unknowable, a real essence. This conclusion will allow me to attribute to Kant a position I label as “regulative essentialism”, meaning that real essences have an indispensable role in accordance with the rational interest to explain nature as a system of laws and natural kinds, combined with an epistemic humility about the correspondence of our empirical concepts to real essences. (shrink)

In the chapter of the Critique of Pure Reason entitled ‘The Discipline of Pure Reason in Dogmatic Use’, Kant contrasts mathematical and philosophical knowledge in order to show that pure reason does not (and, indeed, cannot) pursue philosophical truth according to the same method that it uses to pursue and attain the apodictically certain truths of mathematics. In the process of this comparison, Kant gives the most explicit statement of his critical philosophy of mathematics; accordingly, scholars have typically focused their (...) interpretations and criticisms of Kant’s conception of mathematics on this small section of the Critique.

Spinoza developed a highly interesting metaphysical theory of nature and individuality. In this paper, I endeavor to bring forward some ideas on how Spinozistic views on extended substance, physical world, and individuality can be approached using the concept of power as the basis of interpretation. Jonathan Bennett's ‘field metaphysical’ interpretation of Spinoza's doctrine of one extended substance has generated much discussion, and forms the other starting point of my paper. I believe that the field metaphysical interpretation enables one to deal (...) with the central questions concerning physical individuation — individuality and the persistence of individual being — in a rather novel way. My main question is this: what follows if physical individuals are seen as parts of a unified field of extended power? (shrink)

Kant criticizes the so-called ‘preformation’ hypothesis – a nativist account of the origin of the categories – at the end of the B-Deduction on the ground that it entails scepticism. I examine the historical context of Kant's criticism, and identify the targets as both Crusius and Leibniz. There are two claims argued for in this paper: first, that attending to the context of the opposition to certain forms of nativism affords a way of understanding Kant's commitment to the so-called ‘discursivity (...) thesis’, by contrasting the possession conditions for the categories with those for innate ideas; secondly, it provides an insight with regard to Kant's understanding of the dialectic with scepticism. Kant's claim is that a certain explanatory lacuna that attaches to Humean empiricism can be seen to apply equally to any nativist theory. The lacuna concerns the explanation of the modal purport of a priori necessity, i.e. how it is that our consciousness can even distinguish contents that are represented as necessary features of objects.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

I argue that, by the time of his essay "Concerning the Ultimate Ground of the Differentiation of Directions in Space" (1768), Kant had come to question the status of the Principle of Sufficient Reason as a result, at least in part, of his recognition of the existence of incongruent counterparts. Though Kant's argument against absolute space based on the existence of incongruent counterparts has been much discussed in recent years, its importance as a useful benchmark by which to judge the (...) direction of Kant’s thinking during this period has gone unnoticed. This paper is a modest attempt to remedy this deficiency. (shrink)

I propose that we interpret Kant’s argument from incongruent counterparts in the 1768 article ‘Concerning the Ultimate Ground of the Differentiation of Directions in Space’ in light of a theory of dynamic absolute space that he accepted throughout the 1750s and 1760s. This force-based or material conception of space was not an unusual interpretation of the Newtonian notion of absolute space. Nevertheless, commentators have continually argued that Kant’s argument is an utter failure that shifts from the metaphysics of space to (...) its epistemology, because he has no way to connect ‘directionality’ and ‘handedness’ to absolute space. This supposed failure is based on an understanding of absolute space in purely mathematical terms and as an absolute void that lacks any qualitative or dynamic features. If we recognize that Kant held that space had an intrinsic directional asymmetry then his argument successfully connects incongruent counterparts to absolute space. The presence of this notion in Kant’s pre-Critical thought is rarely noted, and its necessity in understanding his incongruence argument is novel. (shrink)

This paper sets out an account of hermeneutics as essentially ‘topological’ in character at the same time as it also argues that hermeneutics has a key role to play in making clear the nature of the topological. At the centre of the argument is the idea that place and understanding are intimately connected, that this is what determines the interconnection between topology and hermeneutics, and that this also implies an intimate belonging-together of place and thinking, of place and experience, of (...) place and the very possibility of appearance, of presence, of being.

Individual, family, economic, and other forms of people suffering impact organizations. Suffering in the workplace is probably a more common occurrence than expected in everyday life, and opposite to health and employee wellbeing. According to the World Health Organization, 300 million people worldwide struggle with depression and close to 800.000 people die due to suicide every year. The European Survey on Working Conditions in the European Union gathers the most varied aspects of working conditions, such as the duration of the (...) working day, relationships between collaborators in organizations, or healthy work habits. Among the results of that survey it is noteworthy that almost half of the close to twenty-two thousand workers surveyed in the 27 member countries stated that they felt uneasiness due to the conditions of their work.

Diego Bubbio, Ingo Farin and Glenda Satne have advanced a range of comments, questions and challenges relating to the ideas and arguments set out in the new edition of my Place and Experience (2018). Rather than address each of my interlocutors separately, my responses here are organized around four main topics: the relation between space and place, including the nature of space; the relation between place and subjectivity, and the foundational role of place; the relation between place and conceptuality; and (...) the relation between place and normativity.

Bolzano incorporated Kant's distinction between intuitions and concepts into the doctrine of propositions by distinguishing between conceptual (Begriffssätze an sich) and intuitive propositions (Anschauungssätze an sich). An intuitive proposition contains at least one objective intuition, that is, a simple idea that represents exactly one object; a conceptual proposition contains no objective intuition. After Bolzano, philosophers dispensed with the distinction between conceptual and intuitive propositions. So why did Bolzano attach philosophical importance to it? I will argue that, ultimately, the value of (...) the distinction lies in the fact that conceptual and intuitive truths have different objective grounds: if a conceptual truth is grounded at all, its ground is a conceptual truth. The difference in grounds between conceptual and intuitive truths motivates Bolzano's criticism of Kant's view that intuition plays the fundamental role in mathematics, a conceptual science by Bolzano's lights.

In the section “Validity and Existence in Logik, Book III,” I explain Lotze’s famous distinction between existence and validity in Book III of Logik. In the following section, “Lotze’s Platonism,” I put this famous distinction in the context of Lotze’s attempt to distinguish his own position from hypostatic Platonism and consider one way of drawing the distinction: the hypostatic Platonist accepts that there are propositions, whereas Lotze rejects this. In the section “Two Perspectives on Frege’s Platonism,” I argue that this (...) is an unsatisfactory way of reading Lotze’s Platonism and that the Ricketts-Reck reading of Frege is in fact the correct way of thinking about Lotze’s Platonism.

It is quite common when explicating the nature of Kant's break with the preceding Early Modern tradition to cite his attitude towards the acquisition and deployment of concepts. It is claimed that Kant sought to distinguish two tasks that had become unfortunately intertwined and conflated — explaining how we come to acquire our concepts on the one hand and showing how we are justified in deploying them in judgement on the other. This conflation can be expressed in terms of a (...) conflation of the natural and the normative, of descriptive and prescriptive questions. The topic of the conditions ofconcept-possession, i.e. how we have come to possess the concepts that we do, is an entirely psychological inquiry, involving ‘natural’ descriptive inquiries. The topic ofconcept-deployment, the story about how we use our concepts in veridical judgements about the world, is an entirely philosophical question, since it involves the question of how weoughtto deploy those concepts in judgement. The fundamental distinction between the natural and the normative is drawn by Kant, it is claimed, in order to distinguish these two practices of acquisition and deployment.The manner in which this claim is expressed is through Kant's distinction between the question of fact (quaestio facti) and the question of right (quaestio juris). I want to claim that a proper understanding of this distinction doesn't support this notion of Kant's ‘normative turn’. In fact, the distinction is best understood within an interpretation whereby Kant is understood as continuing to endorse the Early Modern conviction that the provision of a concept's possession-conditionsissufficient to determine that concept's deployment-conditions, and that the task of the Transcendental Deduction is to determine thepossession-conditions for the Categories.

En la tradición ilustrada de Kant y en la tradición aristotélica de Tomás de Aquino encontramos los mismos elementos para explicar la experiencia moral: razón práctica del hombre común, ley moral, voluntad, inclinaciones naturales. Pero la relación de estos elementos entre sí varía radicalmente de una tradición a otra, ya que en la tradición kantiana la razón práctica y la ley moral son completamente heterogéneas respecto a las inclinaciones naturales. En la tradición aristotélica de Tomás de Aquino, en cambio, la (...) razón práctica que conoce la ley moral es parte de la naturaleza del hombre. En la tradición kantiana la ética se encuentra completamente separada de la antropología, y no se conoce a partir de la experiencia. En la tradición aristotélico-tomista, la ética se conoce a partir de la experiencia y su conocimiento es explicable a partir de ella. Both Kant’s Enlightenment tradition and Aquinas’ Aristotelian tradition will usually manage the same elements in order to explain the reality of moral experience, namely: practical reason of the common man, moral law, will, and natural inclinations. Yet the relation existing between these elements certainly varies from one tradition to the other since, within Kantian tradition, practical reason and moral law are completely heterogeneous with regard to natural inclinations. On the contrary, within Aquinas’ Aristotelian tradition, the same practical reason that recognizes the moral law is itself an element of human nature as well. Thus, according to Kantian tradition, ethics are totally detached from anthropology, and they are not grasped out of experience. Aristotelian-Thomistic tradition would state that ethics are grasped through experience and, although they are certainly not derived from anthropology, this later would make the grasping of the former explicable.

In the Appendix to the Transcendental Dialectic, Kant formulates teleological principles, or rather ideas, and explicates them referring to concrete examples of natural science such as chemistry, astronomy, biology, empirical psychology, and physical geography. Despite the increasing interest in the systematic relevance of the Appendix to the Transcendental Dialectic and its importance for Kant’s conception of natural science, the numerous historical sources for the regulative use of reason have not yet been investigated. One that is very central is Maupertuis’ principle (...) of least action. In 1781, Kant transformed teleology into heuristics and methodology, but in doing so, he partially develops a teleology which was disqualified by Maupertuis because its starting point lies in the construction of animals or plants, the structure of the earth, and the immensity of the celestial bodies. Based on Maupertuis’ principle of action, it can be shown that the Appendix forms a systematic interface between Universal Natural History and Theory of the Heavens and Critique of Judgement which allows the reconstruction of Kant’s regulative use of reason and its specific status in the context of natural science and his critical appraisal of Maupertuis.

Dedekind’s methodology, in his classic booklet on the foundations of arithmetic, has been the topic of some debate. While some authors make it closely analogue to Hilbert’s early axiomatics, others emphasize its idiosyncratic features, most importantly the fact that no axioms are stated and its careful deductive structure apparently rests on definitions alone. In particular, the so-called Dedekind “axioms” of arithmetic are presented by him as “characteristic conditions” in the _definition_ of the complex concept of a _simply infinite_ system. Making (...) sense of Dedekind’s method may be dependent on an analysis of the classical model of deductive science, as presented by authors from the eighteenth and early nineteenth centuries. Studying the modern reconstructions of Euclidean geometry, we show that they did not presuppose deductive independence of the axioms from the definitions. Authors like Wolff elaborated a mathematics _based on definitions_, and the Wolffian model of deductive science shows significant coincidences with Dedekind’s method, despite the great differences in content and approach. Wolff had a conception of definitions as _genetic_, which bears some similarities with Kant’s idea of synthetic definitions: they are understood as positing the content of mathematical concepts and introducing thought objects (_Gedankendinge_) that are the objects of mathematics. The emphasis on the spontaneity of the understanding, which can be found in this philosophical tradition, can also be fruitfully related with Dedekind’s idea of the “free creation” of mathematical objects.

Matter’s real essence is a ground for certain features of phenomena. Things in themselves are likewise a ground for certain features of phenomena. How do these claims relate? The former is a causal essentialism about physics, Stang argues; and the features so grounded are phenomenally nomically necessary. The latter involves a distinctive ontology of things in themselves, I argue; but the features so grounded are not noumenally nomically necessary. Stang’s version of Kant’s modal metaphysics is admirable, but does not go (...) far enough. Kant’s causal essentialism involves the essences of fundamental properties, as well as of matter. And things in themselves are grounds, because they are substances, the ‘substrate’ of phenomena. (shrink)

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 is concerned with the attempt to base a general theory of value on an idealist metaphysics. The most explicit and fully developed instance of this approach is, of course, found in Kant, on whom I shall concentrate, though I will also suggest that the account I offer of Kant has application to the later German idealists. While the core of the paper is devoted to commentary on Kant, what I thereby wish to make plausible is the idea that (...) Kant's endeavour to base a general conception of value on an idealist metaphysics is of contemporary, not merely historical, interest. Specifically, my suggestion will be that a correct understanding of what is demanded by our ordinary, pre-philosophical grasp of value shows there is reason to think that something along the lines of Kant's transcendental idealism is required for a fully adequate metaphysics of value. Essential to the case I will make is a distinction between Kant's moral theory and his broader account of value, my claim being that, whether or not Kantian moral theory is ultimately dependent on any metaphysics, the broader conception of value to be found in Kant cannot be detached from his doctrine of transcendental idealism.

Prolegomena §38 is intended to elucidate the claim that the understanding legislates a priori laws to nature. Kant cites various laws of geometry as examples and discusses a derivation of the inverse-square law from such laws. I address 4 key interpretive questions about this cryptic text that have not yet received satisfying answers: How exactly are Kant's examples of laws supposed to elucidate the Legislation Thesis? What is Kant's view of the epistemic status of the inverse-square law and, relatedly, of (...) the legitimacy of the geometric derivation of that law? Whose account of laws, the understanding, and space is Kant critiquing in the passage? What positive account of the relationship between laws, the understanding, and space is Kant offering in the passage? My answer to depends crucially on my answers to –. As I interpret Kant, he holds that a wide range of a priori laws—including geometric laws, the inverse-square law, and the universal laws discussed in the Analytic of Principles—are ‘grounded’ in categorial syntheses rather than the intrinsic nature of the space given to us in pure intuition.

This paper shows that Kant's investigation into mathematical purposiveness was central to the development of his understanding of synthetic a priori knowledge. Specifically, it provides a clear historical explanation as to why Kant points to mathematics as an exemplary case of the synthetic a priori, argues that his early analysis of mathematical purposiveness provides a clue to the metaphysical context and motives from which his understanding of synthetic a-priori knowledge emerged, and provides an analysis of the underlying structure of mathematical (...) purposiveness itself, which can be described as unintentional, but also as objective and unlimited.

In Critique of the Power of Judgment, Kant claims organisms are to be judged as ‘natural ends’, which are products of nature but inexplicable by mechanical laws of nature. The conception of natural ends necessarily leads to the idea of nature in its whole as a system of ends. This paper proposes an interpretation of Kant’s biological teleology that can be compatible with modern science. Mechanical laws in the third Critique are understood as empirical causal laws that determine all phenomena. (...) A living organism is mechanically inexplicable, not because it falls outside of mechanical laws, but because the reciprocal productions of its parts are unifiable under its whole, as if designed by an intelligent agency according to the concept of the whole. Once we judge teleologically the mechanical laws determining the organic productions, we must judge teleologically all productions determined by these laws and therefore conceive nature in its whole as a system of ends, to which natural mechanism is subordinated.

Kant’s claim in the Subjective Deduction that we have multiple fundamental mental powers appears to be susceptible to some a priori metaphysical arguments made against multiple fundamental mental powers by Christian Wolff who held that these powers would violate the unity of thought and entail that the soul is an extended composite. I argue, however, that in the Second Paralogism and his lectures on metaphysics, Kant provides arguments that overcome these objections by showing that it is possible that a composite (...) could ground the unity of thought, that properties are powers and therefore the soul could possess multiple powers, and the soul is a thing in itself so it cannot be an extended composite. These arguments lend additional support to the attribution of multiple mental powers to us in the Subjective Deduction. (shrink)

Existential grounding is the thesis that all existential generalizations are grounded in their particular instances. This paper argues that existential grounding is false. This is because it is inconsistent with two plausible claims about existence: the claim that singular existence facts are generalizations and the claim that no object can be involved in a fact that grounds that same object's existence. Not only are these claims intuitively plausible, but there are also strong arguments in favour of each of them.

I demonstrate that the pre-Critical Kant is essentialist and intellectualist about the relational properties of substances. That is to say, God can choose whether or not to create a substance, and whether or not to connect this substance with other substances, so as to create a world: but God cannot choose what the nature of the relational properties is, once the substance is created and connected. The divine will is constrained by the essences of substances. Nonetheless, Kant considers that essences (...) depend upon God, in that they depend upon the divine intellect. I conclude by gesturing towards some possible implications of this interpretation, when considering the role that might be played by God – both historically and conceptually – in relation to the notion of ‘laws of nature’, and when understanding Kant's transcendental idealism and his Critical conception of freedom.

In this debate article I respond to Alison Assiter's various objections and points regarding my work on Kant's empirical realism, his relation to ontology, and related issues. Although Assiter raises some very interesting and important issues, I do not find her ontological interpretation of Kant sufficiently supported textually, and I think her objections to my work are too dependent on omissions and mistaken assumptions to provide an effective challenge.
