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.     

Kant's Argument that Existence is not a Determination

In this paper, I examine Kant's famous objection to the ontological argument: existence is not a determination. Previous commentators have not adequately explained what this claim means, how it undermines the ontological argument, or how Kant argues for it. I argue that the claim that existence is not a determination means that it is not possible for there to be non‐existent objects; necessarily, there are only existent objects. I argue further that Kant's target is not merely ontological arguments as such but the larger ‘ontotheist’ metaphysics they presuppose: the view that God necessarily exists in virtue of his essence being contained in, or logically entailed by, his essence. I show that the ontotheist explanation of divine necessity requires the assumption that existence is a determination, and I show that Descartes and Leibniz are implicitly committed to this in their published versions of the ontological argument. I consider the philosophical motivations for the claim that existence is a determination and then I examine Kant's arguments in the Critique of Pure Reason against it.     

Kant and Hegel on freedom: Two new interpretations

Can Kant's theory of freedom be defended in contemporary ‘incompatibilist’ terms, as Henry Allison believes, or is it vulnerable to Hegelian criticisms of the ‘compatibilist’ sort that Allen Wood presents? I argue that the answer to both of these questions is negative, and that there is a third option, namely that Kant's real theory of freedom is not as well off as Allison contends, nor as weak as Wood claims. Allison tries to save Kant's theory of freedom from both what he takes to be traditional and improper interpretations ‐ notably including Hegel's and Wood's ‐ of what that theory means, as well as from traditional and improper objections to its defensibility. I argue in part with Wood (and Hegel) against Allison on the issue of the meaning of Kant's theory, and in part with Allison against Wood (and Hegel) on the issue of the defensibility of Kant's theory.     

Descartes,Malebranche and Leibniz: conceptions of substance in arguments for the immateriality of the soul

ABSTRACT

The most prominent early modern argument against materialism is to be found in Descartes. Previously I had argued that this argument relies crucially on a robust conception of substance, according to which it has a single principal attribute of which all its other intrinsic qualities are modes. In the present paper I return to this claim. In Section 2, I address a question that is often raised about that conception of substance: its commitment to the idea that a substance has a single such principal attribute. Gonzalo Rodriguez-Pereyra and Daniel Garber have argued that this claim relies on Descartes's identification of substance with attribute. But I argue that it relies on his view that a substance has a single, unitary nature. In Section 3, I examine the role of this conception of substance in arguments found in Malebranche and Leibniz and compare these arguments with Descartes's.     

Once More unto the Breach: Kant and Race

The last thirty years has seen an explosion of literature on Kant and race. Once overlooked essays and notes in which Kant expresses contempt for nonwhite people and support for slavery have been brought to light, and many scholars have wrestled with the question of how a philosopher who stressed the equal dignity of all human beings could hold such views. This article tries to reframe the debate over these issues. It begins by reviewing the racist texts in Kant's corpus and the responses to them proposed by scholars like Charles Mills (to whom the paper is dedicated), Robert Bernasconi, and Pauline Kleingeld. It then introduces elements of Kant's philosophical development that gave Kant reason to renounce his racism—whether or not he actually did so—from about the time of the Groundwork onward. Finally, it turns to the question of what Kant's racism can tell us about his moral philosophy—and perhaps about moral philosophy in general.

Both Wittgenstein and Kant Beg the Question

I shall show that the main argument forms of Wittgenstein's Tractatus and Kant's Critique of Pure Reason are Modus Tollens. I shall then argue that the main arguments of both books beg the question by addressing only one sub‐argument in each, although it is still in controversy whether begging the question is a genuine fallacy.     

Analysing the Good Will: Kant's Argument in the First Section of the Groundwork

This article contends that the first section of Kant's Groundwork of the Metaphysics of Morals provides a sophisticated and valid argument, and that commentators are therefore mistaken in dismissing this section as flawed. In particular, the article undertakes to show that in this section Kant argues from a conception of the goodness of a good will to two distinctive features of moral goodness, and from these features to his ‘formula of universal law’. The article reveals the sophistication and validity of this argument by considering it in the light of a number of criticisms that are commonly levelled at the section. In conclusion, the article proposes that this interpretation of the section also has significant implications for the understanding of Kant's method, his formulas and his basic conception of the ‘moral’.     

Perception and the Categories: A Conceptualist Reading of Kant's Critique of Pure Reason

Abstract: Philosophers interested in Kant's relevance to contemporary debates over the nature of mental content—notably Robert Hanna and Lucy Allais—have argued that Kant ought to be credited with being the original proponent of the existence of ‘nonconceptual content’. However, I think the ‘nonconceptualist’ interpretations that Hanna and Allais give do not show that Kant allowed for nonconceptual content as they construe it. I argue, on the basis of an analysis of certain sections of the A and B editions of the Transcendental Deduction, for a ‘conceptualist’ reading of Kant's Critique of Pure Reason. My contention is that since Kant's notion of empirical intuition makes essential reference to the categories, it must be true for him that no empirical intuition can be given in sensibility independently of the understanding and its categories.     

Kant's Argument for the Apperception Principle

Abstract: My aim is to reconstruct Kant's argument for the principle of the synthetic unity of apperception. I reconstruct Kant's argument in stages, first showing why thinking should be conceived as an activity of synthesis (as opposed to attention), and then showing why the unity or coherence of a subject's representations should depend upon an a priori synthesis. The guiding thread of my account is Kant's conception of enlightenment: as I suggest, the philosophy of mind advanced in the Deduction belongs to an enlightenment epistemology. Kant's conception of enlightenment turns on the requirement that a subject be able to recognize herself as the source of her cognitions. The argument for the apperception principle is reconstructed under the guidance of this conception of the ideal of enlightenment.     

The Principle of Sufficient Reason,the Ontological Argument and the Is/Ought Distinction

Kant's attack on metaphysics consists in large part in his attack on a principle that he names the Supreme Principle of Pure Reason. This principle, it is not often noticed, is the Principle of Sufficient Reason [PSR]. In interpreting this principle as such, I argue that Kant's attack on the PSR (and thereby his attack on dogmatic metaphysics as a whole) depends on Kant's claim that existence is not a first‐order predicate. If existence isn't what Kant calls a real predicate, the PSR is false. While this constitutes a powerful Kantian argument against dogmatic rationalism, it also poses a problem for Kant. For, as I argue, if the PSR is true, Kant's argument that existence isn't a first‐order predicate is false. In this sense, Kant's attack on the PSR is begging the question vis‐á‐vis radical metaphysicians (e.g. Spinoza). Concluding the paper I suggest relying on Kant's 'is'/'ought' distinction in avoiding this circularity, thereby reinforcing the Kantian critique.     

Fine-Tuning,Atheist Criticism,and the Fifth Way

Abstract

Like the “modern watchmaker” argument formulated by William Paley, the argument from fine-tuning should not be confused with Thomas Aquinas' fifth proof for the existence of God as expressed in the Summa Theologiae. While the former is based on efficient causality, the latter is based upon final causality. Though some atheist criticisms are relevant to the fine-tuning argument, they do not affect the Fifth Way. After briefly expositing the fine-tuning argument, I will argue that Aquinas' argument from the “governance of the world” offers a more convincing proof for God—one that evades atheistic criticisms leveled against design arguments.     

Kant and the Problem of Idealism: On the Significance of the Göttingen Review

This essay examines the impact of the Göttingen review on Kant. Taking up each of the charges laid down in this first, critical review of the Critique of Pure Reason, I will argue that these criticisms stem largely from Kant's account in his discussion of the Paralogisms, before going on to defend Kant from the claim that he altered his stance on realism—in reaction to the review—as the only hope for distinguishing transcendental idealism from the immaterialism of George Berkeley.     

German Idealism and the Concept of Punishment

This paper examines the Leibnizian background to Kant's critique of the ontological argument. I present Kant's claim that existence is not a real predicate, already formulated in his pre-critical essay of 1673, as a generalization of Leibniz's reasoning regarding the existence of created things. The first section studies Leibniz's equivocations on the notion of existence and shows that he employs two distinct notions of existence – one for God and another for created substances. The second section examines Kant's position in his early paper of 1763. My claim is that Kant's view of existence in 1763, namely that it is not a predicate, is strongly related to the logical notion of possibility, formulated by Leibniz and accepted by Kant.     

The Phenomenological Failure of Groundwork III

Henry Allison and Paul Guyer have recently offered interpretations of Kant's argument in Groundwork III. These interpretations share this premise: the argument moves from a non-moral, theoretical premise to a moral conclusion, and the failure of the argument is a failure to make this jump from the non-moral to the moral. This characterization both of the nature of the argument and its failure is flawed. Consider instead the possibility that in Groundwork III, Kant is struggling toward something rather different from this, not trying to pull the moral rabbit out of the theoretical hat, but instead seeking a proto-phenomenological grounding of morality: a grounding that begins from first personal felt experiences that already possess moral content, and proceeds to its further practical claims via attentive reflection on these felt experiences. This paper brings this assumption to our reading of Groundwork III, showing that in doing so we acquire a deeper appreciation both of the argument, and the reasons it fails. Kant's argument is practical throughout. And the failure of the argument is the failure of Kant's nascent efforts to provide a new, phenomenological method for the grounding of practical philosophy.     

Kant's Schematism of the categories: An interpretation and defence

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.     

The Moral Argument for the Existence of God and Immortality

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

Hegel on Space: A Critique of Kant's Transcendental Philosophy

This paper considers Hegel's views on space and his account of Kant's theory of space. I show that Hegel's discussions of space exhibit a deep understanding of Kant's apriority argument in the first Critique , commit him to the central premise of that argument, and separate his concerns from the familiar problem of the neglected alternative. Nevertheless, Hegel makes two objections to Kant's theory of space. First, he argues that the theory is internally inconsistent insofar as Kant's identification of space with an a priori intuition is incompatible with the doctrine of productive imagination in the transcendental deduction of the categories. Second, Hegel argues that the apriority argument is insufficiently critical insofar as it relies upon an unexamined theory of subjectivity as a set of representational capacities. I conclude by outlining Hegel's strategy for undermining the assumptions concerning subjectivity that give form to Kant's transcendental philosophy. Because Hegel's positive views on space depend upon his articulation of an alternate notion of subjectivity, the account of Hegel's position on space offered here remains incomplete. On the other hand, considering Hegel's discussions of space demonstrates both the nature and the importance of his examination of subjectivity in the Phenomenology.     

Adorno on Kant,Freedom and Determinism

Abstract: In this paper I argue that Adorno's metacritique of freedom in Negative Dialectics and related texts remains fruitful today. I begin with some background on Adorno's conception of ‘metacritique’ and on Kant's conception of freedom, as I understand it. Next, I discuss Adorno's analysis of the experiential content of Kantian freedom, according to which Kant has reified the particular social experience of the early modern bourgeoisie in his conception of unconditioned freedom. Adorno argues against this conception of freedom and suggests that freedom is always conditioned by our embodiment and by our social and historical situation. Finally, I turn to Adorno's criticism of Kant's discussion of freedom and determinism in the Critique of Pure Reason and argue that while his philosophical argument against Kant fails, his metacritical argument remains suggestive. Scepticism about freedom arises when the standpoint of theoretical reason encroaches upon the standpoint of practical reason and assimilates persons to things.
