This paper shows the ways in which Kant’s notions of the feeling of life and the feeling of the promotion of life may be influenced by Epicurus’ theory of pleasure and the Stoic notion of oikeiôsis, respectively. Accordingly, getting a clear picture of Epicurus’ theory of pleasure and the Stoic notion of oikeiôsis will help us (i) understand why Kant introduces these notions in the third Critique and (ii) why he identifies aesthetic pleasure with the feeling of the promotion of (...) life. As I will demonstrate, the feeling of life allows us to be conscious of the harmonious interaction of our faculties with each other while the feeling of the promotion of life allows us to be aware of the harmonious relationship between our faculties and nature. Hence, the feeling of the promotion of life indicates the well-being of the subject in its relation to its environment. (shrink)

Kant’s early critics maintained that his theory of freedom faces a dilemma: either it reduces the will’s activity to strict necessity by making it subject to the causality of the moral law, or it reduces the will’s activity to blind chance by liberating it from rules of any kind. This Element offers a new interpretation of Kant’s theory against the backdrop of this controversy. It argues that Kant was a consistent proponent of the claim that the moral law is the (...) causal law of a free will, and that the supposed ability of free will to choose indifferently between options is an empty concept. Freedom, for Kant, is a power to initiate action from oneself, and the only way to exercise this power is through the law of one’s own will, the moral law. Immoral action is not thereby rendered impossible, but it also does not express a genuine ability. (shrink)

In recent times, Kant’s theory of the moral feeling of respect has increasingly come to the centre of Kant research. His diverse and seemingly contradictory characterisations of this feeling in particular have led to continued controversial discussion. While a number of scholars try to understand the special role of respect in Kant by isolating this feeling from its conceptual context or solely referring to its role as moral motivation, I will concentrate on the systemic position of respect within the framework (...) of Kant’s theory of the autonomy of reason. Furthermore, I will try to elucidate the different characterisations of respect given by Kant, referring not only to his ethics, but also to his general theory of transcendental idealism. Examining the special place of respect within Kant’s transcendental idealism, I will plead for a compatibilist reading of respect, according to which the “intellectualist” as well as the “affectivist” view both hold true. This is motivated by interpreting respect as a volitional structure featuring rational as well as emotional dimensions. (shrink)

From the perspective of successive events, chemical reactions are expressed or thought about, in terms of the cause-effect category. In this work, I will firstly discuss some aspects of causation and interaction in chemistry, argue for the interaction, and propose an alternative or complementary representation scheme called “interaction diagram”, that allows representing chemical reactions through a geometric diagram. The understanding of this diagram facilitates the analysis of reactions in terms of the interaction, or reciprocal action, among the participating entities. Secondly, (...) I will describe the model and provide examples and finally, I will discuss the scope and limitations of the current development status of the model. (shrink)

The previous two parts of the paper demonstrate that the interpretation of Fermat’s last theorem (FLT) in Hilbert arithmetic meant both in a narrow sense and in a wide sense can suggest a proof by induction in Part I and by means of the Kochen - Specker theorem in Part II. The same interpretation can serve also for a proof FLT based on Gleason’s theorem and partly similar to that in Part II. The concept of (probabilistic) measure of a subspace (...) of Hilbert space and especially its uniqueness can be unambiguously linked to that of partial algebra or incommensurability, or interpreted as a relation of the two dual branches of Hilbert arithmetic in a wide sense. The investigation of the last relation allows for FLT and Gleason’s theorem to be equated in a sense, as two dual counterparts, and the former to be inferred from the latter, as well as vice versa under an additional condition relevant to the Gödel incompleteness of arithmetic to set theory. The qubit Hilbert space itself in turn can be interpreted by the unity of FLT and Gleason’s theorem. The proof of such a fundamental result in number theory as FLT by means of Hilbert arithmetic in a wide sense can be generalized to an idea about “quantum number theory”. It is able to research mathematically the origin of Peano arithmetic from Hilbert arithmetic by mediation of the “nonstandard bijection” and its two dual branches inherently linking it to information theory. Then, infinitesimal analysis and its revolutionary application to physics can be also re-realized in that wider context, for example, as an exploration of the way for physical quantity of time (respectively, for time derivative in any temporal process considered in physics) to appear at all. Finally, the result admits a philosophical reflection of how any hierarchy arises or changes itself only thanks to its dual and idempotent counterpart. (shrink)

A variety of interpreters have argued that Kant construes the animality of human beings as ‘transformed’, in some sense, through the possession of rationality. I argue that this interpretation admits of multiple readings and that it is either wrong, or doesn't result in the conclusion for which its proponents argue. I also explain the sense in which rationality nevertheless significantly differentiates human beings from other animals.

In this paper I extend the case for a necessitation account of particular laws in Kant's philosophy of science by examining the relation between reason's hypothetical use in the Appendix to the Transcendental Dialectic and the legitimate hypotheses identified in the Doctrine of Method. Building on normative accounts of reason's ideas, I argue that reason's hypothetical use does not describe the connections between objects and their grounds, which lie beyond the reach of the understanding, but merely prescribes the relations between (...) appearances and their conditions, for which the understanding must seek. A legitimate hypothesis, I suggest, is a proposition we hold to be true that fills in one or several of those relations. The problematic character of hypotheses requires that we evaluate our reasons for holding them to be true. While natural modality is grounded in the nature of things, which cannot be fully known, our reasons for assent can and must be grounded on features of objects that are epistemically available to us. (shrink)

The aim of the Schematism chapter of the Critique of Pure Reason is to solve the problem posed by the “inhomogeneity” of intuitions and categories: the sensible properties of objects represented in intuition are of a different kind than the properties represented by categories. Kant's solution is to introduce what he calls “transcendental schemata,” which mediate the subsumption of objects under categories. I reconstruct Kant's solution in terms of two substantive premises, which I call Subsumption Sufficiency (i.e., that subsuming an (...) object under a transcendental schema is sufficient to subsume it under the corresponding category) and Real Possibility (i.e., that it is really possible to subsume objects under each of the transcendental schemata). These two principles, together with a trivial modal one (the Subsumption-Possibility Link), entail that it is possible to subsume objects under categories; in other words, the argument of the Schematism is valid. The main work of the paper consists in reconstructing Kant's arguments for, and explanations of, these premises. I argue that they hinge on Kant's claim that transcendental schemata are “time-determinations,” which I interpret to mean: rules for reflexively representing the temporal relations among our own representational states. On the basis of this reading, I reconstruct Kant's argument for Subsumption Sufficiency, category by category. I also explain why Real Possibility follows almost immediately. Granting Kant the argument up to this point in the Critique, the argument of the Schematism is sound. (shrink)

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)

‘Race’ is a highly contested category. What is Race? Four Philosophical Views brings together four leading philosophers of race to advance their theories and engage with each other. The result is a must-read for any philosopher of race and a highly valuable resource for anyone trying to understand this important and complex topic.

Discovering laws of nature was a way to worship a law-giving God, during the Scientific Revolution. So why should we consider it worthwhile now, in our own more secularized science? For historical perspective, I examine two competing early modern theological traditions that related laws of nature to different divine attributes, and their secular legacy in views ranging from Kant and Nietzsche to Humean and ‘governing’ accounts in recent analytic metaphysics. Tracing these branching offshoots of ethically charged God-concepts sheds light on (...) how our ethical ideals and ideas of natural order can still be valuably integrated. Early modern intellectualists valued the law-governed order of nature as a sign of divine Reason. In turn, Reason traditionally ascribed to God has now been partly reclaimed for humans, reframing the value of natural order anthropocentrically, in terms of the value of our own intelligence. Alternatively, Reason may be reclaimed for nature itself, as in an ‘objective’ idealism or metaphysical rationalism. However, beyond divine Reason, an influential voluntarist tradition in theology stressed a connection between laws of nature and God’s Power or free Will. Tracking how divine Power has been reinvested in human beings provides a broader context for instrumentalism and related lineages of empiricism. But secularization can also transfer Power from God to the impersonal natural world. In this light, current scientific interest in lawlike order may also reflect the inherent value of brute necessity or inhuman causal power in nature: this is a deeper way to reject anthropocentrism and to show our respect for the environment.

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.

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 conception of the centrality of intellectual self-consciousness, or “pure apperception”, for scientific knowledge of nature is well known, if still obscure. Here I argue that, for Kant, at least one central role for such self-consciousness lies in the acquisition of the content of concepts central to metaphysical theorizing. I focus on one important concept, that of <substance>. I argue that, for Kant, the representational content of the concept <substance> depends not just on the capacity for apperception, but on the (...) actual intellectual awareness of oneself in such apperception. I then defend this interpretation from a variety of objections. (shrink)

I argue for a new delimitation of what Kant means by ‘cognition [Erkenntnis]’, on the basis of the intermediate, transitional place that Kant gives to cognition in the ‘progression [Stufenleiter]’ of our representations and our consciousness of them. I show how cognition differs from mental acts lying earlier on this progression—such as sensing, intuiting, and perceiving—and also how cognition differs from acts lying later on this progression—such as explaining, having insight, and comprehending. I also argue that cognition should not be (...) confused with ‘knowledge [Wissen]’, insofar as knowledge represents the culmination of a separate orthogonal progression of acts of ‘holding-true’. Along the way, I show how having in focus the specific progression from representation, to consciousness, to cognition allows us to better appreciate the architectonic significance of the progression of Kant’s analysis in the first Critique, and also helps to illuminate the unity of Kant’s account of cognition itself across its variety of forms. (shrink)

Few of Kant’s distinctions have generated as much puzzlement and criticism as the one he draws in the Prolegomena between judgments of experience, which he describes as objectively and universally valid, and judgments of perception, which he says are merely subjectively valid. Yet the distinction between objective and subjective validity is central to Kant’s account of experience and plays a key role in his Transcendental Deduction of the categories. In this paper, I reject a standard interpretation of the distinction, according (...) to which judgments of perception are merely subjectively valid because they are made without sufficient investigation. In its place, I argue that for Kant, judgments of perception are merely subjectively valid because they merely report sequences of perceptions had by a subject without claiming that what is represented by the perceptions is connected in the objects the perceptions are of. Whereas the interpretation I criticize undercuts Kant’s strategy in the Deduction, I argue, my interpretation illuminates it. (shrink)

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

Kant’s postulate of possibility states that possible is whatever agrees with the formal conditions of experience. As has often been noted, this is a definition of real possibility. However, little attention has been paid to the relation of Kantian real possibility to the German philosophical tradition before him. I discuss three kinds of possibility present in this tradition – internal, external, and (Crusian) real possibility – and argue that Kant endorses internal and external possibility. Furthermore, I show, specifically with respect (...) to the concept of state (Zustand), that the three traditional conceptions are reminiscent of three conceptions of real possibility that Kant implicitly distinguishes. Lastly, I argue that, according to Kant, we need experience to prove real possibility (at least as regards the three conceptions of the real possibility of states) because otherwise we could not know whether the formal conditions of experience obtain. (shrink)

This paper investigates Kant’s account of “real essence” and of a thing’s “nature”. Notwithstanding their wide negligence in the literature, these concepts belong to the central ones of Kant’s metaphysics. I argue that, on the one hand, Kant is in continuity with the Aristotelian-Scholastic tradition of essence. But, on the other hand, he also follows Locke in distinguishing between “logical” and “real” essence. Contrary to recent attempts of aligning real essence with contemporary approaches to essence, I will defend the thesis (...) that Kant equates real essence and (formal) nature, and that real essence has a causal, but no constitutive role. I shall also respond to potential objections and discuss some developments of Kant’s views. (shrink)

ABSTRACT Kant famously claims that we have all freely chosen evil. This paper offers a novel account of the much-debated justification for this claim. I reconstruct Kant’s argument from his affirmation that we all have a price – we can all succumb to temptation. I argue that this follows a priori from a theoretical principle of the Critique of Pure Reason, namely that all empirical powers have a finite, changeable degree, an intensive magnitude. Because of this, our reason can always (...) be overpowered by sensible inclinations. Kant moreover holds that this necessary feature of our moral psychology should not have been the case: We ought to instead be like the divine human being, for whom the moral law yields a greater incentive than any possible temptation. On Kant’s view, we are thus responsible for having a price, and the synthetic a priori fact that we do proves that we each made an initial choice of evil. (shrink)

Kant holds that the applicability of the moral ‘ought’ depends on a kind of agent-causal freedom that is incompatible with the deterministic structure of phenomenal nature. I argue that Kant understands this determinism to threaten not just morality but the very possibility of our status as rational beings. Rational beings exemplify “cognitive control” in all of their actions, including not just rational willing and the formation of doxastic attitudes, but also more basic cognitive acts such as judging, conceptualizing, and synthesizing.

Objects have dispositions. Dispositions are normally analyzed by providing a meaning to disposition ascriptions like ‘This piece of salt is soluble’. Philosophers like Carnap, Goodman, Quine, Lewis and many others have proposed analyses of such disposition ascriptions. In this paper we will argue with Quine that the proper analysis of ascriptions of the form ‘x is disposed to m ’, where ‘x’ denotes an object, ‘m’ a manifestation, and ‘C’ a condition, goes like this: ‘x is of natural kind k’, (...) and the generic ‘ks are m ’ is true. For the analysis of the generic, we propose an analysis in terms of causal powers: ‘ks have the causal power to m’. The latter, in turn, is analyzed in a very precise way, making use of Pearl’s probabilistic graphical causal models. We will show how this natural kind-analysis improves on standard conditional analyses of dispositions by avoiding the standard counterexamples, and that it gives rise to precise observable criteria under which the disposition ascription is true.

I argue that the descriptions of perceptual experience offered by Kant and Merleau-Ponty are, contrary to what many commentators suppose, largely compatible. This is because the two are simply referring to different things when they talk about experience: Kant to empirical cognition and Merleau-Ponty to perception. Consequently, while Merleau-Ponty correctly denies that Kant accurately describes the conditions for the possibility of perception, Kant nevertheless provides a plausible account of the conditions of empirical judgment. Further, the two approach experience with different (...) standards of normativity: Kant with the standard of justification, but Merleau-Ponty with the standard of what he calls “motivation”. I exemplify this approach through an analysis of the Second Analogy of Experience. (shrink)

I argue for a new delimitation of what Kant means by ‘cognition [Erkenntnis]’, on the basis of the intermediate, transitional place that Kant gives to cognition in the ‘progression [Stufenleiter]’ of our representations and our consciousness of them. I show how cognition differs from mental acts lying earlier on this progression—such as sensing, intuiting, and perceiving—and also how cognition differs from acts lying later on this progression—such as explaining, having insight, and comprehending. I also argue that cognition should not be (...) confused with ‘knowledge [Wissen]’, insofar as knowledge represents the culmination of a separate orthogonal progression of acts of ‘holding-true’. Along the way, I show how having in focus the specific progression from representation, to consciousness, to cognition (and beyond) allows us to better appreciate the architectonic significance of the progression of Kant’s analysis in the first Critique (and beyond), and also helps to illuminate the unity of Kant’s account of cognition itself across its variety of (empirical, mathematical, philosophical) forms. (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. (shrink)

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)

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)

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)

On 11thOctober 2007, at the first international conference on Integrated History and Philosophy of Science (&HPS1) hosted by the Center for Philosophy of Science in Pittsburgh, Ernan McMullin (University of Notre Dame) portrayed a rather gloomy scenario concerning the current relationship between history and philosophy of science (HPS), on the one hand, and mainstream philosophy, on the other hand, as testified by a significant drop in the presence of HPS papers at various meetings of the American Philosophical Association (APA).

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 [...].

According to recent commentators like Paul Guyer, Kant agrees with Hume's Dialogues Concerning Natural Religion that physico-theology can never provide knowledge of God and that the concept of God, nevertheless, provides a useful heuristic principle for scientific enquiry. This paper argues that Kant, far from agreeing with Hume, criticizes Hume's Dialogues for failing to prove that physico-theology can never yield knowledge of God and that Kant correctly views Hume's Dialogues as a threat to, rather than an anticipation of, his own (...) view that the concept of God provides a useful heuristic principle for science. The paper concludes that Kant's critique of physico-theology reflects Kant's deep dissatisfaction with Hume's manner of argumentation and suggests that Kant's attempt to provide a more successful critique of physico-theology merits continued philosophical attention.

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.

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.

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)

In this dissertation, I provide an interpretation and defense of Merleau-Ponty's thesis of the primacy of perception, namely, the thesis that all knowledge is founded in perceptual experience. I take as an interpretative and argumentative key Merleau-Ponty's phenomenological conception of motivation. Whereas epistemology has traditionally accepted a dichotomy between reason and natural causality, I show that this dichotomy is not exhaustive of the forms of epistemic grounding. There is a third type of grounding, the one characteristic of the grounding relations (...) found in perception: motivation. I argue that introducing motivation as a form of epistemic grounding allows us to see how Merleau-Ponty's thesis of the primacy of perception avoids both rationalism and empiricism. Whereas empiricism has argued that all the content of our knowledge is grounded in causal interactions between the world and our senses, and rationalism has held that experience does not suffice as a reason for knowledge, thinking of the relation between experience and knowledge in terms of motivation accommodates the best insights of rationalism and empiricism. Motivation allows us to see how knowledge can be grounded in experience without the content of knowledge being reducible to that of experience. (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.

El artículo trata de una reflexión que presupone un largo trajinar con los textos de Kant, ofrece pautas para la lectura de la obra filosófica. En primer lugar, atender a su incompletud, dado que es de su ser el ser continuada en la reflexión de los problemas que trata. En el caso específico de la filosofía de Kant, se enfatiza en la polivalencia de sus conceptos fundamentales, así como en la mundaneidad de los mismos.

This essay discusses how, for Hegel, freedom can be realized in nature in a rudimentary fashion in solar systems. This solves a problem in Kant’s account of freedom, namely, the problem that Kant only gives a negative argument for why freedom is not impossible but does not give a positive account of how freedom is real. I give a novel account of Kant’s negative argument. Then, I show how, according to Hegel, solar systems can be considered as exhibiting freedom in (...) a rudimentary fashion. Finally, I lay out how Hegel systematically develops this point about the freedom of solar systems in the ‘Mechanism’-chapter of the Science of Logic. In doing so, he uses Kant’s negative argument in a ‘purified’ form to arrive at an account of an ‘intimate token-type relation’ between the planets in a solar system and the law that governs their motion. The essay as a whole provides a concrete example of how Hegel is an inheritor and radicalizer of Kant, both with respect to freedom’s reality and with respect to philosophical method. (shrink)

In this paper, I give an explanation and defense of Kant’s claim that we cannot comprehend how freedom is possible. I argue that this is a significant point that has been underappreciated in the secondary literature. My conclusion has a variety of implications both for Kant scholars and for those interested in Kantian ideas more generally. Most notably, if Kant is right that there are principled reasons why freedom is beyond our comprehension, then this would release his ethical views from (...) an undesirable explanatory burden. It would be a boon for Kantians if they could ground their lofty claims about the unique, elevated status of rational agency without committing to an implausible view of libertarian freedom. I also suggest that there are certain debates concerning moral motivation and transcendental idealism that might have to change in response to Kant’s claims about the incomprehensibility of freedom.
