kant’s critique of pure reason undertakes a systematic investigation of the possibility of synthetic cognition a priori so as to determine whether this kind of cognition is possible in the case of traditional metaphysics.1 While much scholarly attention has been devoted to the distinction between analytic and synthetic judgments as well as to that between the a priori and the a posteriori, less attention has been devoted to understanding exactly what cognition is for Kant. In particular, it is often insufficiently (...) clear what kind of mental state cognition is, what the exact nature of the conditions on cognition is, and how they are satisfied in the case of human beings. To bring greater clarity to... (shrink)

This paper offers a new interpretation of Kant's puzzling claim that the B-Deduction in the Critique of Pure Reason should be considered as having two main steps. Previous commentators have tended to agree in general on the first step as arguing for the necessity of the categories for possible experience, but disagree on what the second step is and whether Kant even needs a second step. I argue that the two parts of the B-Deduction correspond to the two aspects of (...) a priori cognition: necessity and universality. The bulk of the paper consists of support for the second step, the universality of the categories. I show that Kant's arguments in the second half of the B-Deduction aim to define the scope of that universality for possible experience by considering the possibilities of divine intellectual intuition, of non-human kinds of sensible intuition, and of apperception of the self. In these ways Kant delimits the boundaries of the applicability of the categories and excludes any other possible experience for human beings. (shrink)

This essay partly builds on and partly criticizes a striking idea of Dieter Henrich. Henrich argues that Kant's distinction in the first Critique between the question of fact (quid facti) and the question of law (quid juris) provides clues to the argumentative structure of a philosophical "Deduction". Henrich suggests that the unity of apperception plays a role analogous to a legal factum. By contrast, I argue, first, that the question of fact in the first Critique is settled by the Metaphysical (...) Deduction, which establishes the purity of origin of the Categories, and, second, that in the second Critique, the relevant factum is the Fact of Reason, which amounts to the fact that the Moral Law is pure in origin.

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. (shrink)

In this book, the first to describe and assess Hume's influence throughout Kant's philosophy, Guyer shows where Kant agrees or disagrees with Hume, and where Kant does or doesn't appear to resolve Hume's doubts.

The common assumption that the Transcendental Deduction aims to refute scepticism often leads interpreters to conclude that it fails and even that Kant is confused about what it is supposed to achieve. By examining what Kant himself says concerning the Deductions' relation to scepticism, this article seeks to determine what sort of scepticism he has in view and how he responds to it. It concludes that the Deduction aims neither to refute Cartesian, outer- world scepticism nor to refute Humean, empiricist (...) scepticism, and it outlines an alternative conception of the Deduction's task, as one of reconciling apparently conflicting claims of reason.

In this paper, I claim that Kant’s subjective deduction in the first edition of the KrV is to be understood in terms of an investigation of the fundamental force(s) (Grundkraft) of the soul, an investigation essential to Wolffian psychology and much debated throughout Germany in the second half of the 1700’s. I argue that the subjective deduction is indeed presented by means of the exposition of the three-fold syntheses but only insofar as these syntheses are employed as pointers towards each (...) of three original sources of cognition. Only taken as such can we do justice not only to the argument’s unique concern as distinct from that of the objective deduction, but also to its dependence upon the justificatory results of that deduction which was after all Kant’s “primary concern”.

Most work in Kant’s epistemology focuses on what happens “upstream” from experience, prior to the formation of conscious propositional attitudes. By contrast, this essay focuses on what happens "downstream": the formation of assent (Fuerwahrhalten) in its various modes. The mode of assent that Kant calls "Belief" (Glaube) is the main topic: not only moral Belief but also "pragmatic" and "doctrinal" Belief as well. I argue that Kant’s discussion shows that we should reject standard accounts of the extent to which theoretical (...) reason can provide justified assent about things-in-themselves, in favor of one that is much more liberal. Interpretive benefits are not the only results of the discussion, however. I also hope it will become clear along the way that there is such a thing as Kantian Belief, and that we often have quite a lot of it. -/- . (shrink)

In the transcendental deduction, the central argument of the Critique of Pure Reason, Kant seeks to secure the objective validity of our basic categories of thought. He distinguishes objective and subjective sides of this argument. The latter side, the subjective deduction, is normally understood as an investigation of our cognitive faculties. It is identified with Kant’s account of a threefold synthesis involved in our cognition of objects of experience, and it is said to precede and ground Kant’s proof of the (...) validity of the categories in the objective deduction. I challenge this standard reading of the subjective deduction, arguing, first, that there is little textual evidence for it, and, second, that it encourages a problematic conception of how the deduction works. In its place, I present a new reading of the subjective deduction. Rather than being a broad investigation of our cognitive faculties, it should be seen as addressing a specific worry that arises in the course of the objective deduction. The latter establishes the need for a necessary connection between our capacities for thinking and being given objects, but Kant acknowledges that his readers might struggle to comprehend how these seemingly independent capacities are coordinated. Even worse, they might well believe that in asserting this necessary connection, Kant’s position amounts to an implausible subjective idealism. The subjective deduction ismeant to allay these concerns by showing that they rest on a misunderstanding of the relation between these faculties. This new reading of the subjective deduction offers a better fit with Kant’s text. It also has broader implications, for it reveals the more philosophically plausible account of our relation to the world as thinkers that Kant is defending – an account that is largely obscured by the standard reading of the subjective deduction.

Kant wrote two versions of the Transcendental Deduction, the first, “A-”Deduction in 1781, and the second, “B-”Deduction in 1787. Since Henrich's “The Proof Structure of Kant's Transcendental Deduction”, most work on the Transcendental Deduction attempts to make sense of the B-Deduction's two-step argument structure. Though the A-Deduction has suffered comparative neglect, it has received some attention from interpreters who take its extended treatment of the “subjective” side of cognition to amount to a brand of proto-functionalism. Whatever the merits and demerits (...) of these proto-functionalist approaches, they tend to deemphasize the two arguments that constitute the “objective” side of the A-Deduction, the “argument from above” and then the “argument from below”. Since Kant himself refers to this objective side of the A-Deduction as the “Deduction of the Pure Concepts of the Understanding”, it is surprising that the structure of these arguments has not received closer scrutiny. This is doubly true since Kant actually claims that his revisions for the 1787 version of the Deduction impacted only the “presentation” of it. Any lessons learned from the central arguments of the A-Deduction should help clarify the structure of its younger and more closely studied brother. (shrink)

Major recent interpretations of Kant's first "critique" (wolff, Strawson, Bennett) have taken his transcendental deduction to be an argument from the fact of consciousness to the existence of an objective world. I argue that it is unclear such an argument can succeed and there are overwhelming reasons to believe kant understood his deduction as having a very different form, namely as moving from the premise that there is empirical knowledge to the conclusion that there are universally valid pure categories. Detailed (...) support for this contention is offered in an analysis of the second edition version of the deduction. (shrink)

:Space is not an empirical concept that has been drawn from outer experiences. For in order for certain sensations to be related to something outside me , thus in order for me to represent them as outside and next to one another, thus not merely different but as in different places, the representation of space must already be their ground. Thus the representation of space cannot be obtained from the relations of outer appearance through experience, but this outer experience is (...) itself first possible only through this representation. 1Abstract:Der Raum is kein empirischer Begriff, der von äußeren Erfahrungen abgezogen worden. Denn damit gewisse Empfindungen auf etwas außer mir bezogen werden, imgleichen damit ich sie als außer und neben einander, mithin nicht bloß verschieden, sondern als in verschiedenen Orten vorstellen können, dazu muß die Vorstellung des Raumes schon zum Grunde liegen.

Descartes's general rule that “whatever is clearly and distinctly perceived is true” has traditionally been criticized on two closely related grounds. As Leibniz, for example, puts it, clearness and distinctness are of no value as criteria of truth unless we have criteria of clearness and distinctness; but Descartes gives none. And consequently, the standards of judgment which the rule in fact evokes are purely subjective and psychological. There must hence be set up analytic, logical “marks” by means of which it (...) can infallibly and without arbitrariness be recognized whether any ideas or propositions are or are not clear and distinct.

According to Kant, if an agent acts according to his/her conscience, then s/he has done all that s/he ought as far as morality is concerned. But Kant thinks that agents can be mistaken in their subjective determinations of their duties. That is, Kant thinks it is possible for an agent to believe that some action X is right even though it is an objective truth that X is not right; according to Kant, agents do not have infallible knowledge of right (...) and wrong. In this paper, I explore this doctrine in order to determine whether it is defensible. In particular, I confront the blameworthiness of acting contrary to fallible knowledge and the blamelessness of acting according to fallible judgment. (shrink)

Kant is often considered to have argued that perceptual awareness of objects in one's environment depends on the subject's possession of conceptual capacities. This conceptualist interpretation raises an immediate problem concerning the nature of perceptual awareness in non-rational, non-concept using animals. In this paper I argue that Kant’s claims concerning animal representation and consciousness do not foreclose the possibility of attributing to animals the capacity for objective perceptual consciousness, and that a non-conceptualist interpretation of Kant’s position concerning perceptual awareness can (...) actively endorse this attribution. Kant can consistently allow that animals have a point of view on the objective world which possesses a distinctive phenomenal character while denying what seems most important to him – viz. that animals have the capacity to take cognitive attitudes towards, and thus self-ascribe, their own representational states.

Controversies are boiling these days among distinguished men over true and false ideas. This is an issue of great importance for recognizing truth—an issue on which Descartes himself is not altogether satisfactory. So I want to explain briefly what I think can be established about the distinctions and criteria that relate to ideas and knowledge. [Here and in..
