For all their differences, the transcendental philosophies of Kant and Deleuze converge on the need for a principle of the determination of what is given to sensation. This principle, the point of contact between the determined and undetermined, would be a ground of sensation and therefore of all outer experience. For both Kant and Deleuze, this ground can be localised in intensity as the degree of force of the real. But it is Deleuze's unique combination to show that depth, the (...) matrix of intensity, serves as a ground only insofar as it is also an ungrounding. (shrink)

What is it that makes a mental state conscious? Recent commentators have proposed that for Kant, consciousness results from differentiation: A mental state is conscious insofar as it is distinguished, by means of our conceptual capacities, from other states and/or things. I argue instead that Kant’s conception of state consciousness is sensory: A mental state is conscious insofar as it is accompanied by an inner sensation. Interpreting state consciousness as inner sensation reveals an underappreciated influence of Crusius on Kant’s view, (...) solves some long-standing puzzles concerning Kant’s difficult doctrine of self-affection, and sheds light on his theory of inner experience.

It is commonly thought that the distinction between subjectively valid judgements of perception and objectively valid judgements of experience in the Prolegomena is not consistent with the account of judgement Kant offers in the B Deduction, according to which a judgement is ‘nothing other than the way to bring given cognitions to the objective unity of apperception’. Contrary to this view, I argue that the Prolegomena distinction maps closely onto that drawn between the mathematical and dynamical principles in the System (...) of Principles: Kant’s account of the Prolegomena distinction strongly suggests that it is the Analogies of Experience that make it possible for judgements of perception to give rise to judgements of experience. This means that judgements of perception are objectively valid with regard to the quantity and quality of objects, and subjectively valid with regard to the relation they posit between objects. If that is the case, then the notion of a judgement of perception is consistent with the B Deduction account of judgement. (shrink)

There are some necessary conditions on causal relations that seem to be so trivial that they do not merit further inquiry. Many philosophers assume that the requirement that there could be no temporal gaps between causes and their effects is such a condition. Bertrand Russell disagrees. In this paper, an in-depth discussion of Russell’s argument against this necessary condition is the centerpiece of an analysis of what is at stake when one accepts or denies that there can be temporal gaps (...) between causes and effects. It is argued that whether one accepts or denies this condition, one is implicated in taking on substantial and wide-ranging philosophical positions. Therefore, it is not a trivial necessary condition of causal relations and it merits further inquiry. (shrink)

According to Kant each person has an empirical character, which is ultimately grounded in one’s free choice. The popular Causal Laws interpretation of empirical character holds that it consists of the causal laws governing our psychology. I argue that this reading has difficulties explaining moral change, the ‘gradual reformation’ of our empirical character: Causal laws cannot change and hence cannot be gradually reformed. I propose an alternative Causal Powers interpretation of empirical character, where our empirical character consists of our mind’s (...) causal powers. The resulting picture of empirical character allows for moral change and Kantian weakness of will. (shrink)

The paper contrasts Kant's conception of original common possession of the earth with Hugo Grotius's superficially similar notion. The aim is not only to elucidate how much Kant departs from his natural law predecessors—given that Grotius's needs-based framework very much lines in with contemporary theorists’ tendency to reduce issues of global concern to questions of how to divide the world up, it also seeks to advocate Kant's global thinking as an alternative for current debates. Crucially, it is Kant's radical shift (...) in perspective—from an Archimedean ’view from nowhere‘, to a first-personal standpoint through which agents reflexively recognise their systematic interdependence in a world of limited space—that provides him with the more thorough and ultimately convincing global standpoint. This standpoint does not come with ready-made solutions to shared global problems, but provides a promising perspective from which to theorise them. (shrink)

This essay examines the relationship between monads and space in Kant’s early pre-critical work, with special attention devoted to the question of ubeity, a Scholastic doctrine that Leibniz describes as “ways of being somewhere”. By focusing attention on this concept, evidence will be put forward that supports the claim, held by various scholars, that the monad-space relationship in Kant is closer to Leibniz’ original conception than the hypotheses typically offered by the later Leibniz-Wolff school. In addition, Kant’s monadology, in conjunction (...) with God’s role, also helps to shed light on further aspects of his system that are broadly Leibnizian, such as monadic activity and the unity of space.

Ott (2009) identifies two kinds of philosophical theories about laws: top-down, and bottom-up. An influential top-down reading, exemplified by Ernst Cassirer, emphasized the ‘mere form of law’. Recent bottom-up accounts emphasize the mind-independent natures of objects as the basis of laws of nature. Stang and Pollok in turn focus on the transcendental idealist elements of Kant’s theory of matter, which leads to the question: is the essence of Kantian matter that it obeys the form of law? I argue that Kant (...) has an independent theory of matter in the Metaphysical Foundations of Natural Science, one that gives what Kant himself calls a ‘real definition’ of matter as a theory-independent (if not mind-independent) entity. I argue that this matter theory underpins physical arguments about inertia and impenetrability, which resemble Einstein’s arguments about the unification of fields in general relativity. (shrink)

In the Metaphysical Foundations of Natural Science, Kant presents an argument for the centrality of <motion> to our concept <matter>. This argument has long been considered either irredeemably obscure or otherwise defective. In this paper I provide an interpretation which defends the argument’s validity and clarifies the sense in which it aims to show that <motion> is fundamental to our conception of matter.

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)

Consider the laws of nature—the laws of physics, for example. One familiar philosophical question about laws is this: what is it to be a law of nature? More specifically, is a law of nature a regularity, or a generalization stating a regularity? Or is it something else? Another philosophical question is: how, and to what extent, can we have knowledge of the laws of nature? I am interested here in Kant's answers to these questions, and their place within his broader (...) theoretical philosophy during the period spanning from the first to the third Critique. (shrink)

Are the pure intuitions of space and time, for Kant, dependent upon the understanding's activity? This paper defends the recently popular Self-Affection Thesis : namely, that the pure intuitions require an activity of self-affection—an influence of the understanding on the inner sense. Two systematic objections to this thesis have been raised: The Independence objection claims that SAT undermines the independence of sensibility; the Compatibility objection claims that certain features of space and time are incompatible with being the products of the (...) understanding's activity. I show that the resources to rebut these objections can be found in Kant's account of causal influence. (shrink)

This thesis is devoted to studying two historical philosophical events that happened in the West and the East. A metaphysical crisis stimulated Kant’s writings during his late critical period towards the notion of the supersensible. It further motivated a methodological shift and his coining of reflective judgment, which eventually brought about a systemic unfolding of his critical philosophy via Kantian moral teleology. Zhu Xi and his Neo-Confucian contemporaries confronted a transformed intellectual landscape resulting from the Neo-Daoist and Buddhist discourses of (...) “what is beyond the form”. The revival of Confucianism required a method in order to relocate the formless Dao back into daily life and to reconstruct a meta-ethical foundation within a social context. This led to the Neo-Confucian recasting of “investigation of things” from The Great Learning via complex hermeneutic operations. By the respective investigation on, as well as the comparative analysis of the two events, I reveal the convergence and incommensurability between the two distinct cultural traditions concerning the metaphysical quests, the mechanism of intellectual development, and moral teleology, so as to capture the intrinsic characteristics of philosophical research in general.

Kant claims that we cannot cognize the mutual interaction of substances without their being in space; he also claims that we cannot cognize a ‘spatial community’ among substances without their being in mutual interaction. I situate these theses in their historical context and consider Kant’s reasons for accepting them. I argue that they rest on commitments regarding the metaphysical grounding of, first, the possibility of mutual interaction among substances-as-appearances and, second, the actuality of specific distance-relations among such substances. By illuminating (...) these commitments, I shed light on Kant’s metaphysics of space and its relation to Newton and Leibniz’s views. (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.

I propose a new way of understanding Kant’s doctrine of freedom. My reading seeks to combine features of two popular opposed lines of interpretation, namely, of metaphysical and anti-metaphysical readings. I defend the view that Kant’s idealist attempt to ‘save’ human freedom involves substantive metaphysical commitments. However, I show that this interpretation can fruitfully integrate important insights that are standardly associated with deflationary readings: first, the idea that for Kant freedom and natural necessity can be ascribed to one and the (...) same human being; and second, the idea that for Kant the belief in freedom and the belief in natural necessity belong to two different standpoints. (shrink)

A well-known trilemma faces the interpretation of Kant’s theory of affection, namely whether the objects that affect us are empirical, noumenal, or both. I argue that according to Kant, the things that affect us and cause representations in us are not empirical objects. I articulate what I call the Causal Power Argument, according to which empirical objects cannot affect us because they do not have the right kind of power to cause representations. All the causal powers that empirical objects have (...) are moving powers, and such powers can only have spatial effects. According to Kant, however, the representations that arise in us as a result of the affection of our sensibility are non-spatial. I show that this argument is put forward by Kant in a number of passages, and figures as a decisive reason for rejecting empirical affection and instead endorsing affection by the things in themselves.

Das Verb „anfangen“ lässt sich sowohl mit einem Akteur an Subjektstelle als auch subjektlos verwenden. Sogenannte subjektlose Sätze wie „Es fängt zu regnen an“ haben freilich ein grammatisches Subjekt, aber auf die Rückfrage „Wer oder was fängt zu regnen an?“ ist die einzig mögliche Antwort „Es“ unbefriedigend. Das grammatische Subjekt fungiert in solchen Sätzen lediglich als synkategorematischer Ausdruck. Menschliche Akteure können in gehaltvollerem Sinn etwas anfangen, zum Beispiel Streit, oder, wie es bei Kant heißt, „eine Reihe von Begebenheiten“. Mit dem (...) emphatisch beschriebenen Vermögen, „eine Reihe von Begebenheiten ganz von selbst anzufangen“, bestimmt Kant das Anfangen einer Handlung als Vermögen der Erstverursachung und verschafft ihm so die gebührende Fallhöhe. Diese beiden Verwendungen von „anfangen“ markieren die Spannung zwischen dem bloßen Beginnen eines subjektlosen Naturprozesses und dem Vermögen, ein Geschehen aktiv in Gang zu setzen. Ich möchte in diesem Beitrag vier klassische Modelle des Anfangens einer Handlung diskutieren, um ihre wichtigsten Vorzüge und Nachteile miteinander zu vergleichen: die kausale Handlungstheorie, die Theorie der Akteurskausalität, die des mentalen Steuerimpulses und die der noumenalen Kausalität. Klassisch sind die vier Modelle, insofern man sie philosophiehistorisch wie folgt verorten kann: (1) Das humesche Modell: kausale Handlungstheorie, (2) Das aristotelische Modell: Akteurskausalität, (3) Das cartesische Modell: mentaler Steuerimpuls, (4) Das kantische Modell: noumenale Kausalität [...].

On an influential view, Newton's mechanics is built into Kant's very theory of exact knowledge. However, Newtonian dynamics had serious explanatory limits already known by 1750. Thus, we might worry that Kant's Analytic is too narrow to ground enough exact knowledge. In this paper, I draw on Enlightenment dynamics to show that Kant's notion of determinate objecthood is sufficiently broad, non-trivial, and still relevant to the present.

In this paper, I consider Baumgarten’s views on the soul in the context of the Pietist critique of Wolff’s rational psychology. My primary aim is to account for the largely unacknowledged differences between Wolff’s and Baumgarten’s rational psychology, though I also hope to show that, in some cases, the Pietists were rather more perceptive in their reading of Wolff than they are typically given credit for as their criticisms frequently succeed in drawing attention to significant omissions in Wolff’s discussion.

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.

Famously, in the second Critique, Kant claims that our consciousness of the moral law provides us with sufficient grounds for the attribution of freedom to ourselves as noumena or things-in-themselves. In this way, while Kant insists that we have no rational basis to make substantive assertions about things-in-themselves from a theoretical point of view, it is rational for us to assert that we are noumenally free from a practical one. This much is uncontroversial. What is controversial is the cognitive relation (...) to things-in-themselves that is possible from a practical point of view. Interpreters have tended to regard such “practical cognition” of things-in-themselves as a poor step-cousin of its theoretical counterpart — as a sort of mere “rational faith” unworthy of comparison with genuine theoretical knowledge or cognition. Recent work on these issues has begun to shift this picture. But this reassessment is in its early stages and remains highly controversial. My aim here is to take this tendency and push it farther than most have generally been willing to go - at least with respect to our practical self-understanding as noumenally free agents. Indeed, I believe that, far from representing an impoverished cousin of theoretical cognition and knowledge, our practical awareness of ourselves as free possesses the central marks of cognition and knowledge in Kant’s sense of these terms, albeit on practical grounds. Thus, it is no surprise that Kant is willing to speak of our consciousness of the moral law as enabling genuine cognition of noumenal freedom. (shrink)

There has been a groundswell of interest in the account of modality that Kant sets forth in his pre-Critical Only Possible Argument. Andrew Chignell's reconstruction of Kant's theistic argument in terms of what he calls has a prima facie advantage in that it appears to be able to block the plurality objection (namely, that even if every modal fact presupposes some ground, this does not entail that all modal facts share the same ground). I argue that it is both textually (...) and philosophically problematic to interpret Kant's argument in terms of real harmony. Then, I set forth an alternative response to the plurality objection which does not require the adoption of the problematic notion of real harmony. Instead, I argue that the objection can be overcome by observing that the argument seeks to ground modal facts as a totality and that, according to Kant, such relations can be accounted for only by their schematization in a single intellect.

Kant's sustained reflections on God have received considerable scholarly attention over the years and rightly so. His provocative criticisms of the three traditional theoretical proofs of the existence of God, and his own positive proof for belief in God's existence on moral grounds, have fully deserved the clarification and analysis that has occurred in these discussions. What I want to focus on, however, is the extent to which Kant's position contains resources sufficient to answer a line of questioning about the (...) existence of God that has recently been called the problem of the ‘hiddenness of God’ in contemporary discussions in philosophy of religion. If God exists roughly as the Judeo-Christian philosophical tradition conceives of him, it is puzzling, at least prima facie, why he does not make his existence overwhelmingly obvious to one and all, but rather is hidden from us. For if God is omnipotent, as the tradition maintains, it seems that he would have the power to reveal himself to us and, for that matter, with sufficient clarity that we would be left with no doubt about the matter. And if, as the tradition maintains further, it is important to God that we accept his existence and reject false idols who would pretend to divine status, it would seem that he has a significant reason to reveal himself to us. In short, given that God can make his existence obvious to all, and that doing so would fulfil an important purpose, why does he remain hidden from us? (shrink)

Quantum indeterminism seems incompatible with Kant’s defense of causality in his Second Analogy. The Copenhagen interpretation also takes quantum theory as evidence for anti-realism. This article argues that the law of causality, as transcendental, applies only to the world as observable, not to hypothetical (unobservable) objects such as quarks, detectable only by high energy accelerators. Taking Planck’s constant and the speed of light as the lower and upper bounds of observability provides a way of interpreting the observables of quantum mechanics (...) as empirically real even though they are transcendentally (i.e., preobservationally) ideal.El indeterminismo cuántico parece incompatible con la defensa de la causalidad que hace Kant en su Segunda Analogía.

In the aftermath of a normalized Foucaultian world with an all encompassing web of biopower, one remaining hope is to cultivate nimbleness. Nimbleness is an embodied aesthetic sensitivity to the material presence. Cultivating nimbleness is a particular style of cultivation; it is to willfully gather together one’s self in the wake of a formative force far richer than the derivative web of living power relationships of human embeddness within a horizon of social, economical, political and historical subjectivating power relations; which (...) are chronicled and labeled by Michel Foucault as the normalizing practices of biopower. In other words to have freedom, one must start by rejecting the categories and labels normally internalized in order to relearn to learn from the material presence. Such a style of cultivation is a means of resisting normalizing power relations which co-opt cultivating practices to engross their own dominance which has had the by-product of an impotence to negate the gross material injustices present. This normalizing style of cultivation is a prevalent, corrupted, semblance which denies the importance of beauty for that of efficiency, rejects non-human purposiveness, and limits its measure of ethics to short term economical pragmatism. The thesis acknowledges that something is awry with the world and that giving care to beauty might help. The aim is to examine the event of Beauty as depicted by the philosopher Immanuel Kant and to apply this characterization to elective architectural spaces such that it may motivate individuals to cultivate their own nimbleness in relation to a formative force of nature. However given the revealed need for sensitivity to the particular material presence, the thesis can not be a rule book or catalog for beautiful design. Rather it is a rehabilitation for architects who are already heterospatially curious, with the desired outcome of architects cultivating their own nimbleness to reflectively judge as a ground up, multi-node, rhizomatic means of resistance to normalizing power practices as manifest in bad architecture.

The interpretation of Kant's Critical philosophy as a version of traditional idealism has a long history. In spite of Kant's and his commentators’ various attempts to distinguish between traditional and transcendental idealism, his philosophy continues to be construed as committed (whether explicitly or implicitly and whether consistently or inconsistently) to various features usually associated with the traditional idealist project. As a result, most often, the accusation is that his Critical philosophy makes too strong metaphysical and epistemological claims.

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.

Eric Watkins has argued on philosophical, textual, and historical grounds that Kant’s account of causation in the first Critique should not be read as an attempt to refute Hume’s account of causation. In this paper, I challenge the arguments for Watkins’ claim. Specifically, I argue (1) that Kant’s philosophical commitments, even on Watkins’ reading, are not obvious obstacles to refuting Hume, (2) that textual evidence from the “Disciple of Pure Reason” suggests Kant conceived of his account of causation as such (...) a refutation, and (3) that none of Hume’s early German critics provided responses to this account that would have satisfied Kant. Watkins’ reading of Kant’s account of causation is thus more compatible with traditional views about Kant’s relationship to Hume than Watkins believes. (shrink)

Kant's notion of ‘discipline’ has received considerable attention from scholars of his philosophy of education, but its role in his theoretical philosophy has been largely ignored. This omission is surprising since his discussion of discipline in the first Critique is not only more extensive and expansive in scope than his other discussions but also predates them. The goal of this essay is to provide a comprehensive reading of the Discipline that emphasizes its systematic importance in the first Critique. I argue (...) that its goal is to establish a set of rules for the use of pure reason that, if followed, will mitigate and perhaps even eliminate our tendency to make judgments about supersensible objects. Since Kant's justification for these rules relies crucially on claims he has defended in the Doctrine of Elements, I argue further that, far from being a dispensable part of the Critique as commentators have tended to claim, the Discipline is, in fact, the culmination of Kant's critique of metaphysics. (shrink)

Hume’s account of causation is often regarded a challenge Kant must overcome if the Critical philosophy is to be successful. But from Kant’s time to the present, Hume’s denial of our ability to cognize supersensible objects, a denial that relies heavily on his account of causation, has also been regarded as a forerunner to Kant’s critique of metaphysics. After identifying reasons for rejecting Wayne Waxman’s recent account of Kant’s debt to Hume, I present my own, more modest account of this (...) debt, an account that seeks to unite the two very different pictures of Kant’s relationship to Hume sketched above.

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.

My contribution to a book symposium on Graham’s commentary on Kant’s Critique of Pure Reason, sponsored by the North American and the UK Kant Societies, held in conjunction with the Central Division Meeting of the American Philosophical Association, Chicago, 20 February 2009.

Dennis Schulting offers a thoroughgoing, analytic account of the first half of the Transcendental Deduction of the Categories in the B-edition of Kant's Critique of Pure Reason that is different from existing interpretations in at least one important aspect: its central claim is that each of the 12 categories is wholly derivable from the principle of apperception, which goes against the current view that the Deduction is not a proof in a strict philosophical sense and the standard reading that in (...) the Deduction Kant only gives an account of the global applicability of the categories to experience. This novel approach enables a reappraisal of Kant's controversial claim that transcendental self-consciousness is not only a necessary condition of objective experience but also sufficient for it. The book provides an extensive analysis of Kant's theory of transcendental apperception and also explains why the argument of the Transcendental Deduction is both a regressive and a progressive argument.

Although Kant (1998) envisaged a prominent role for logic in the argumentative structure of his Critique of Pure Reason, logicians and philosophers have generally judged Kantgeneralformaltranscendental logics is a logic in the strict formal sense, albeit with a semantics and a definition of validity that are vastly more complex than that of first-order logic. The main technical application of the formalism developed here is a formal proof that Kants logic is after all a distinguished subsystem of first-order logic, namely what (...) is known as geometric logic.

In attempts to come to grips with Kant’s thought, the influence of the philosophy of Christian Wolff (1679-1754) is often neglected. In this paper, I consider three topics in Kant’s philosophy of mind, broadly construed, where Wolff’s influence is particularly visible: consciousness, self-consciousness, and psychology. I argue that we can better understand Kant’s particular arguments and positions within this context, but also gain a more accurate sense of which aspects of Kant’s accounts derive from the antecedent traditions and which constitute (...) genuine philosophical innovations. (shrink)

In this paper, I discuss a problem for Kant's strategy of appealing to the agent qua noumenon to undermine the significance of determinism in his theory of free will. I then propose a solution. The problem is as follows: given determinism, how can some agent qua noumenon be 'the cause of the causality' of the appearances of that agent qua phenomenon without being the cause of the entire empirical causal series? This problem has been identified in the literature (Ralph Walker (...) provides what is perhaps the most dramatic presentation of it). But it has never received an adequate solution. In this paper, I argue that Walker’s objection is only decisive if we must understand our responsibility as responsibility for events, but not causal laws. I argue that we need not interpret Kant's theory in this way. I demonstrate that each agent qua noumenon could be responsible for "limited instantiation scope" causal laws which necessitate only the phenomenal actions of that same agent qua phenomenon. Part of this project involves showing that there are relevant constituents of actions which are "rare" enough to instantiate such laws. I demonstrate that, on Kant's view, events in agents’ bodies are not rare enough, but events in agents’ phenomenal souls are. (shrink)

According to Kant, being purely rational or purely reasonable and being autonomously free are one and the same thing. But how can this be so? How can my innate capacity for pure reason ever motivate me to do anything, whether the right thing or the wrong thing? What I will suggest is that the fundamental connection between reason and freedom, both for Kant and in reality, is precisely our human biological life and spontaneity of the will, a conjunctive intrinsic structural (...) property of our animal bodies, which essentially constitutes human personhood and rational agency. I say ‘suggest’ because, obviously, no proper argument for such a conclusion could ever be worked out in a short essay. I would nevertheless like to motivate my suggestion by way of a commentary on the second part of Adrian Moore's extremely rich and interesting recent book, Noble in Reason, Infinite in Faculty.

Kantian constructivists locate the source of normativity in the rational nature of valuing agents. Some further argue that accepting this premise thereby commits one to accepting the intrinsic or unconditioned value of rational nature itself. Whereas much of the critical literature on this “regress on conditions” argument has focused either on the cogency of the inference from the value-conferring capacity of the will to the unconditional value of that capacity itself or on the plausibility of the initial constructivist premise, my (...) aim is to press the argument from a different direction by asking just how Kantian the constructivist needs to be in order to support a regress on conditions argument. Specifically, I maintain that the argument succeeds only given a full-fledged Kantian moral psychology, including a presupposition of transcendental freedom. If correct, this could have implications regarding the compatibility of Kantian ethics and philosophic naturalism. (shrink)

In this paper, I offer a systematic account of Kant’s view on ‘phenomenal substance’. Several studies have recently analyzed Kant’s notion of substance. However, I submit that more needs to be said about how this notion is reconceptualized within the critical framework to vindicate a genuine and legitimate sense of substance in the phenomenal realm. More specifically, I show that Kant’s transcendental idealism does not commit him to a rejection of substantiality in phenomena. Rather, Kant isolates a general notion of (...) substance (as ultimate subject) and argues that (i) the relationality of phenomena is compatible with this notion; and that (ii) matter and all its parts are the ultimate subjects of everything existing in space (as what is independently movable in space). I suggest that vindicating a genuine and legitimate notion of phenomenal substance has far-ranging consequences for the interpretation of Kant’s empirical realism. (shrink)

In this paper, we analyse conceptions of induction and certainty in Wolff and Crusius, highlighting their competing conceptions of physics. We discuss (i) the perspective of Wolff, who assigned induction an important role in physics, but argued that physics should be an axiomatic science containing certain statements, and (ii) the perspective of Crusius, who adopted parts of the ideal of axiomatic physics but criticized the scope of Wolff’s ideal of certain science. Against interpretations that take Wolff’s proofs in physics to (...) be based on empirical statements that are probable, we show how inductively established statements, coupled with assumptions concerning the uniformity of nature, can be certain according to Wolff. We examine Crusius’ little known work on physics and show that he attacked Wolff, arguing that many statements of physics are probable. We provide a discussion of the reception of methodological rules similar to Newton’s Regulae Philosophandi, discussing different interpretations of such rules. We conclude by briefly hinting at how the debate between Wolff and Crusius provides historical context for understanding Kant’s philosophy of natural science. (shrink)

In this introductory article we reconstruct several broad developments in the scholarship on Kant’s theory of natural science with a particular focus on the Anglophone context over the past half-century. Our goal is to illuminate the co-development of Kant scholarship and the philosophy of science during this period and to identify points of influence in both directions. In section 2 we present an overview of the scholarship on Kant’s account of natural laws. In section 3 we survey the diverse interpretations (...) of Kant’s views on biology and consider recent appeals to Kant by philosophers of biology. In section 4 we explore several recent developments in philosophy of science that have potential synergies with Kant scholarship. Our aim is not simply to establish that Kant’s philosophy can have relevance for philosophy of science but also to point out where it has been and continues to be relevant. Appreciating this relevance, we suggest, can help identify productive lines of inquiry for Kant studies. (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.
