Did Kant Conflate the Necessary and the A Priori?

It is commonly accepted by Kant scholars that Kant held that all necessary truths are a priori, and all a priori knowledge is knowledge of necessary truths. Against the prevailing interpretation, I argue that Kant was agnostic as to whether necessity and a priority are co‐extensive. I focus on three kinds of modality Kant implicitly distinguishes: formal possibility and necessity, empirical possibility and necessity, and noumenal possibility and necessity. Formal possibility is compatibility with the forms of experience; empirical possibility is compatibility with the causal powers of empirical objects; noumenal possibility is compatibility with the causal powers of things in themselves. Because we cannot know the causal powers of things in themselves, we cannot know what is noumenally necessary and what is noumenally contingent. Consequently, we cannot know whether noumenal necessity is co‐extensive with a priority. Therefore, for all we know, some a priori propositions are noumenally contingent, and some a posteriori propositions are noumenally necessary. Thus, contrary to the received interpretation, Kant distinguishes epistemological from metaphysical modality.     

Kant’s deductions of morality and freedom

It is commonly held that Kant ventured to derive morality from freedom in Groundwork III. It is also believed that he reversed this strategy in the second Critique, attempting to derive freedom from morality instead. In this paper, I set out to challenge these familiar assumptions: Kant’s argument in Groundwork III rests on a moral conception of the intelligible world, one that plays a similar role as the ‘fact of reason’ in the second Critique. Accordingly, I argue, there is no reversal in the proof-structure of Kant’s two works.     

Continuity of change in Kant’s dynamics

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.

     

Which Kantian Conceptualism (or Nonconceptualism)?

A recent debate in Kant scholarship concerns the role of concepts in Kant's theory of perception. Roughly, proponents of a conceptualist interpretation argue that for Kant, the possession of concepts is a prior condition for perception, while nonconceptualist interpreters deny this. The debate has two parts. One part concerns whether possessing empirical concepts is a prior condition for having empirical intuitions. A second part concerns whether Kant allows empirical intuitions without a priori concepts. Outside of Kant interpretation, the contemporary debate about conceptualism concerns whether perception requires empirical concepts. But, as I argue, the debate about whether Kant allows intuitions without empirical concepts does not show whether Kant is a conceptualist. Even if Kant allows intuitions without empirical concepts, it could still be that a priori concepts are required. While the debate could show that Kant is a conceptualist, I argue it does not. Finally, I sketch a novel way that the conceptualist interpreter might win the debate—roughly, by arguing that possessing a priori concepts is a prior condition for having appearances.     

Skepticism in Kant's Groundwork

This paper offers a new interpretation of Kant's relationship with skepticism in the Groundwork for the Metaphysics of Morals. My position differs from commonly held views in the literature in two ways. On the one hand, I argue that Kant's relationship with skepticism is active and systematic (contrary to Hill, Wood, Rawls, Timmermann, and Allison). On the other hand, I argue that the kind of skepticism Kant is interested in does not speak to the philosophical tradition in any straightforward sense (contrary to Forster and Guyer). On my reading, Kant takes up a skeptical method in the Groundwork as a way of exposing certain obstacles in our ordinary and philosophical thinking about morality. The central obstacle he is interested in is practical in character, arising from a natural tendency we have to rationalize against the moral law. In attempting to resolve this tendency, I argue, the Groundwork turns out to have a profoundly educative task.     

Kant and experimental philosophy

While Kant introduces his critical philosophy in continuity with the experimental tradition begun by Francis Bacon, it is widely accepted that his Copernican revolution places experimental physics outside the bounds of science. Yet scholars have recently contested this view. They argue that in Critique of the Power of Judgment Kant’s engagement with the growing influence of vitalism in the 1780s leads to an account of nature’s formative power that returns experimental physics within scientific parameters. Several critics are sceptical of this revised reading. They argue that Kant’s third Critique serves precisely to deflate the epistemological status of experimental physics, thereby protecting science from the threat of vitalism. In this paper I examine Kant’s account of science in the context of the experimental tradition of philosophy, particularly in relation to the generation dilemma of the eighteenth century. I argue that Kant does not deflate the epistemological status of experimental physics but rather introduces systematicity to the experimental tradition. By identifying the reflective use of reason to organize laws of experience into a systematic whole, Kant aims to ground experimental inquiry on the secure course of a science, opening a conception of science as a research programme.     

A ground completely overgrown: Heidegger,Kant and the problem of metaphysics

ABSTRACT

While we endorse Heidegger’s effort to reclaim Kant’s Critique of Pure Reason as a work concerned with the possibility of metaphysics, we hold, first, that his reading is less original than is often assumed and, second, that it unduly marginalizes the critical impetus of Kant’s philosophy. This article seeks to shed new light on Kant and the Problem of Metaphysics and related texts by relating Heidegger’s interpretation of Kant to, on the one hand, the epistemological approach represented by Cohen’s Kant’s Theory of Experience and, on the other, the metaphysical readings put forward by Heimsoeth, Wundt and others in the 1920s. On this basis, we argue that Heidegger’s interpretation of Kant remains indebted to the methodological distinction between ground and grounded that informed Cohen’s reading and was transferred to the problem of metaphysics by Wundt. Even if Heidegger resists a ‘foundationalist’ mode of this distinction, we argue that his focus on the notions of ground and grounding does not allow him to account for Kant’s critique of the metaphysical tradition.     

Ethical Lessons from Heidegger’s Phenomenological Reading of Kant’s Practical Philosophy: Heideggerian Revision of Kant’s Justification of Morality*

ABSTRACT

In The Essence of Human Freedom, Heidegger suggests that Kant’s idea of pure will and Heidegger’s own idea of resoluteness are rooted in the same experience of demand from our own essence. This experience can unfold, I argue, through twofold self-understanding: first, the primordial self-understanding on the existentiell level that results in the indefiniteness of pure will (or resoluteness), as Heidegger’s phenomenological reading of Kant (or his own existential analysis) presents; and second, the practical self-understanding on the rational level that results in the principle of morality, as Kant’s Groundwork of the Metaphysics of Morals demonstrates. Based on this approach, if we accept Heidegger’s phenomenological interpretation of pure will but do not follow his rejection of the categorical imperative formulas, we can achieve a Heideggerian revision of Kant’s original justification of morality while avoiding Kant’s problematic assumption that the authentic self belongs to the intelligible realm.     

Kant's Opus Postumum and McDowell's Critique of Kant

In this article, I have a modest goal: (1) to sketch how Kant can avoid the charge of “subjective idealism” advanced against him by John McDowell and (2) to do so with reference to Kant's last work, the so‐called Opus Postumum. I am interested in defending Kant on this point because doing so not only (a) shows how we need not—at least not because of this point about idealism—jump ship from Kant to Hegel (as McDowell and others think), but also (b) suggests that the Opus Postumum is a text that ought to be explored more by Kantians and those interested in Kant. A subsidiary, implicit point is that (c) we need not shy away from McDowell's reading of Kant in order to oppose McDowell's criticism of Kant. In order to defend against McDowell's charge, I focus on the argument of the Refutation of Idealism, showing how this argument evolves in Kant's later works, especially the Opus Postumum.     

Making history philosophical: Kant,Maimon, and the evolution of the historiography of philosophy in the critical period

ABSTRACT

In this article I explore Maimon’s role in the evolution of Kant’s understanding of the function of the history of philosophy in philosophical enquiry. Kant is often viewed as holding an ambivalent relation to the history of philosophy. On the one hand, he dismisses past philosophers as victims of transcendental illusion and downplays the value of the historiography of philosophy. On the other hand, by framing his project as a synthesis of several philosophical traditions, Kant embeds the critical philosophy into a sweeping historical narrative in a manner that highlights the importance of the past for present philosophical aims. In this article, I argue that for most of his career Kant held a position reflective of the former view, but that the publication of Maimon’s response to a prize question announced by the Royal Academy led Kant to develop an understanding of the history of philosophy more in line with the latter view. The result is a distinctively post-Kantian model for a ‘philosophical history of philosophy’ that is both methodologically nuanced and potentially relevant to contemporary debates.     

GARRETT ON THE THEOLOGICAL OBJECTION TO HUME'S COMPATIBILISM

Between 1927 and 1936, Martin Heidegger devoted almost one thousand pages of close textual commentary to the philosophy of Immanuel Kant. This article aims to shed new light on the relationship between Kant and Heidegger by providing a fresh analysis of two central texts: Heidegger's 1927/8 lecture course Phenomenological Interpretation of Kant's Critique of Pure Reason and his 1929 monograph Kant and the Problem of Metaphysics. I argue that to make sense of Heidegger's reading of Kant, one must resolve two questions. First, how does Heidegger's Kant understand the concept of the transcendental? Second, what role does the concept of a horizon play in Heidegger's reconstruction of the Critique? I answer the first question by drawing on Cassam's model of a self-directed transcendental argument (‘The role of the transcendental within Heidegger's Kant’), and the second by examining the relationship between Kant's doctrine that ‘pure, general logic’ abstracts from all semantic content and Hume's attack on metaphysics (‘The role of the horizon within Heidegger's Kant’). I close by sketching the implications of my results for Heidegger's own thought (‘From Heidegger's Kant to Sein und Zeit’). Ultimately, I conclude that Heidegger's commentary on the Critical system is defined, above all, by a single issue: the nature of the ‘form’ of intentionality.     

After MacIntyre

In his influential book After Virtue, Alasdair MacIntyre identifies Kierkegaard's view of ethics with that of Kant. Both Kant and Kierkegaard, according to MacIntyre, accept the modern paradigm of moral activity for which freedom of the will is the ultimate basis. Ronald M. Green, in Kierkegaard and Kant: The Hidden Debt, accepts and deepens this alignment between the two thinkers. Green argues that Kierkegaard deliberately obscured his debt to Kant by a systematic “misattribution” of his ideas to other thinkers, and to classical philosophy in particular. This essay argues that MacIntyre and Green are mistaken in identifying Kierkegaard with the Kantian tradition of moral autonomy and that they overlook his debt to the classical conception of virtue. In casting Kierkegaard in the role of the quintessential exponent of a modern conception of freedom, they have perhaps overlooked one of the greatest critics of moral autonomy who has ever lived.     

Kant and Husserl on the Contents of Perception

This paper focuses on the contents of perception in Kant's first Critique and Husserl's later writings. Both Kant and Husserl are known for their appeal to synthesis in their transcendental accounts of perceptual experience and objective judgment. Especially regarding Kant, the precise nature of perceptual synthesis has recently been the cause of much debate. Whereas some argue that for Kant perception must have nonconceptual content, others believe he is a conceptualist. After offering an alternative solution to this interpretative problem in Kant's philosophy, I turn to Husserl's later theory of perception. My main claims here are that Husserl departs from Kant specifically regarding (i) the sort of synthetic contents that govern affective perception and (ii) the role of conceptual capacities in the contents of attentive perception.     

Phenomenology,idealism, and the legacy of Kant

Martin Heidegger closes his Winter Semester 1927–28 lectures by claiming that Kant’s Critique of Pure Reason, read through the lens of Edmund Husserl’s phenomenology, confirmed the accuracy of his philosophical path culminating in Being and Time. A notable interpretation of Heidegger’s debt to Kant, advanced by William Blattner, presents Heidegger as a temporal idealist. I argue that attention to Husserl’s adaptation of Kant’s critical philosophy shows that both Husserl and Heidegger are realists. I make my case by tracing a unified philosophical problematic through three puzzling passages: the Schematism chapter of the first Critique, Husserl’s thought experiment of the destruction of the world in Ideas, and the passage in Being and Time that motivates Blattner’s idealist reading. Husserl and Heidegger give accounts, derived from Kant, of how the consciousness of time makes it possible for objects to be perceived as enduring unities, as well as ‘genealogies of logic’ that show how a priori knowledge, including ontology, is possible. These accounts are idealistic only in the sense that they concern the ideal or essential features of intentionality in virtue of which it puts us in touch with things as they are independently of the contributions of any mind of any type.     

The Art of Becoming Human: Morality in Kant and Confucius

Kant and Confucius maintain that the art of becoming human is synonymous with the unending process of becoming moral. According to Kant, I must imagine a world in which the universality of my maxims were possible, while realizing that if such a world existed, then morality would disappear. Morality is an impossible possibility because it always meets resistance in our encounter with nature. According to Confucius, human beings become moral by integrating themselves into the already meaningful natural order that is tian 天. Like Kant, he upholds the dignity of human beings. For Kant this dignity rests on the autonomy of each human being’s reason, while for Confucius it is dependent upon our interconnection with each other, demanding ongoing self-extension. Despite these differences, the two thinkers would concur that our efforts at humanization are unceasing and that we may never fully live up to our human potential.     

Agency,human nature and character in Kantian theory

Conclusion In order for the duty of friendship to be practically possible, and for gratitude and beneficence to be unencumbered virtues, Kant need not have held that human beings are basically good. He need only have understood that they are social beings, with desires for both independence and connection, autonomy and affiliation, and purposes that are not always merely their own. I have argued that because he did not, his moral theory is flawed in three important respects.In Kant's theory, morality is only possible because humans are rational, and necessary because (absent morality) they are self-interested individuals, egoistically motivated, distrustful and isolated. When this view is applied to particular questions of friendship and the virtues, it becomes a distorting medium. It is my contention that a more adequate theory of character would result from the application of Kantian moral principles to a sounder, more social conception of human nature.In conclusion, I wish to make it clear that I am not arguing that human beings are basically good, only that they are essentially social. In his political writings Kant has emphasized the social dimension of reason itself, and I believe he would agree with Thomas Nagel's recent claim about human nature and morality: To say that altruism and morality are possible in virtue of something basic to human nature is not to say that men are basically good. Men are basically complicated; how good they are depends on whether certain conceptions and ways of thinking have achieved dominance, a dominance which is precarious in any case.

Reviving the no‐bad‐action problem in Kant's ethics

In the final section of the Groundwork, Kant famously declares that “a free will and a will under moral laws are one and the same.” Though this claim is put to use in Kant's eventual deduction of the moral law, it appears to introduce a difficulty of its own: It complicates Kant's ability to describe immoral action as free action. Over the last 3 decades, no scholar has done more to exonerate Kant from this apparent problem than Henry Allison. Allison's chief strategy has been to show (a) that the volitional apparatus (i.e., the executive will) Kant develops in his late Religion is present from the beginning of the critical project and (b) that this apparatus dissolves the apparent worry. In this paper, I argue that even if Allison succeeds in establishing (a), it puts him no closer to establishing (b). Kant does not think that agents, good or bad, can act out of character.     

Global government or global governance? Realism and idealism in Kant's legal theory

Did Kant believe we need a world government? It has been a matter of controversy in Kant scholarship whether Kant endorsed the creation of a world state or merely a voluntary federation of states with no coercive power. I argue that Kant's main concern was with a global juridical condition, which he regarded as a rational requirement given the equal freedom and equality of individuals. However, he recognized that implementing this rational ideal requires sensitivity to contingent aspects of world politics. I will argue that Kant offers an ideal theory not disentangled from realist considerations and that he adopts what I will call methodological realism: the attempt to realize the requirements of Right (Recht) in a world governed by its own laws and mechanisms. I will illustrate this interpretation with Kant's discussion of the right of nations (Völkerrecht). The confusion in regard to Kant's actual position on the matter, I will argue, is a direct consequence of Kant's methodological realism. The article concludes by showing how Kant’'s ideas and methods can inspire us to rethink global institutions for our current global challenges.
