Against a view currently popular in the literature, it is argued that Kant was not a niıve realist about perceptual experience. Naive realism entails that perceptual experience is object-dependent in a very strong sense. In the first half of the paper, I explain what this claim amounts to and I undermine the evidence that has been marshalled in support of attributing it to Kant. In the second half of the paper, I explore in some detail Kant’s account of hallucination and (...) argue that no such account is available to someone who thinks that veridical perceptual experience is object-dependent in the naive realist sense. Kant’s theory provides for a remarkably sophisticated, bottom-up explanation of the phenomenal character of hallucinatory episodes and is crucial for gaining a proper understanding of his model of the mind and its place in nature.

In der "Transzendentalen Ästhetik" der KrV will Kant zeigen, daß Raum und Zeit Anschauungsformen und daher keine Eigenschaften der Dinge an sich sind. Es scheint jedoch, als übersehe er dabei die Möglichkeit, daß Raum und Zeit Anschauungsformen und zugleich Eigenschaften der Dinge an sich sein könnten. Dagegen soll hier gezeigt werden, daß Kants Beweis durchaus schlüssig ist. Dabei kommt es zunächst darauf an, die genaue Struktur des Kantischen Beweises zu verstehen. Darauf folgt eine Diskussion der Kantischen Begriffe Anschauung sowie Form (...) der Anschauung und reine Anschauung, in der sich unter anderem herausstellt, daß Kants Anschauungsbegriff im Sinne der aktuellen Philosophie des Geistes "externalistisch" konzipiert ist. Dies erlaubt es dann, den Schluß auf die Idealität von Raum und Zeit tatsächlich als Folgerung aus Kants vorhergehenden Ausführungen zu verstehen. Abschließend geht es um einige der Konsequenzen, die sich aus dieser Interpretation für das Verständnis des transzendentalen Idealismus ergeben. (shrink)

: Kant's 'argument from geometry' is usually interpreted to be a regressive transcendental argument in support of the claim that we have a pure intuition of space. In this paper I defend an alternative interpretation of this argument according to which it is rather a progressive synthetic argument meant to identify and establish the essential role of pure spatial intuition in geometric cognition. In the course of reinterpreting the 'argument from geometry' I reassess the arguments of the Aesthetic and illustrate (...) the origin of Kant's view of the role of pure intuition in geometry.

T HE heart of Kant's views on the nature of mathematics is his thesis that the judgments of pure mathematics are synthetic a priori. Kant usually offers this as one thesis, but it is fruitful to regard it as consisting of two separate claims, a meta- physical subthesis and an epistemological ..

In the Postulates of Empirical Thinking, a section of the Critique of Pure Reason, Kant presents an account of the content and role of our concept of real possibility in terms of formal conditions of experience. However, much later in the Critique he introduces the idea of a material condition of possibility. What is this material condition of possibility, and how does it fit with the conception of possibility in terms of formal conditions? This essay argues that the key to (...) answering these questions—as well as to understanding Kant’s criticism of rational theology, in which the discussion of the material condition of possibility appears—is Kant’s account of how we can individuate objects.

This paper addresses the question of what we can legitimately say about things in themselves in Kant's critical doctrine. Many Kant scholars believe that Kant allows that things in themselves can be characterized through the unschematized or ‘pure’ concepts of our understanding such as ‘substance’ or ‘causality’. However, I show that on Kant's view things in themselves do not conform to the unschematized categories : the pure categories, like space and time, are merely subjective forms of finite, discursive cognition. I (...) then examine what this interpretation might entail for central aspects of Kant's system such as his doctrine of noumenal freedom. (shrink)

In the Critique of Pure Reason, following his elucidation of the ‘postulates’ of possibility, actuality, and necessity, Kant makes a series of puzzling remarks. He seems to deny the somewhat metaphysically intuitive contention that the extension of possibility is greater than that of actuality, which, in turn, is greater than that of necessity. Further, he states that the actual adds nothing to the possible. This leads to the view, fairly common in the literature, that Kant holds that all modal categories, (...) in their empirical applications, are coextensive. I diverge from the common view. First, Kant is not committed to the coextensiveness thesis, understood as above. Instead, he espouses a weaker, epistemological version of the coextensiveness thesis, namely that what we can assert to be really possible is coextensive with what we cognize to be actual. Second, Kant's remarks are not intended to introduce a positive ontological thesis about the extensions of modal categories. Rather, he means to criticize a certain conception of modalities that was prevalent among his rationalist predecessors, i.e., the conception of modalities as various determinations that enter the intensions of concepts of things.

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

in kant’s account of cognition, Eric Watkins and Marcus Willaschek distinguish between a ‘broad’ and ‘narrow’ sense of Kant’s use of the term ‘cognition.’ Every “conscious representation that represents an object” counts as a cognition, taken in the broad sense.1 Every “conscious representation of a given object and of its general features” counts as a cognition in the narrow sense.2 In the case of finite beings, they argue, cognition in the narrow sense must fulfill two conditions: First, the object must (...) be given, since cognition must actually latch onto an object, and intuition satisfies that condition insofar as it immediately relates to the object represented in the intuition....

This is a very important book. It has already become required reading for researchers on the relation between the exact sciences and Kant’s philosophy. The main theme is that Kant’s continuing program to find a metaphysics that could provide a foundation for the science of his day is of crucial importance to understanding the development of his philosophical thought from its earliest precritical beginnings in the thesis of 1747, right through the highwater years of the critical philosophy, to his last (...) unpublished writings in the Opus postumum. In the course of articulating this theme, Friedman has made extensive use of detailed historical information about their scientific and mathematical background to illuminate Kant’s texts. Over and over again, such information is used to suggest interesting and quite subtle interpretations for texts that may have seemed puzzling or just wrong-headed. (shrink)
