This article argues that many (often Anglophone) interpreters of the Deduction have mistakenly identified Kant's aim as vindicating ordinary knowledge of objects and as refuting Hume's (alleged) skepticism about such knowledge. Instead, the article contends that Kant's aims were primarily negative. His primary mission (in the Deduction) was not to justify application of the categories to experience, but to show that any use beyond the domain of experience could not be justified. To do this, he needed to show that their (...) proper use in attaining metaphysical knowledge was restricted to (actual and possible) experience. The central theoretical claims of previous metaphysics were thus rendered void. Kant was not out to save ordinary knowledge from the skeptic, at least not originally, since he did not think such knowledge was in danger. Rather, he wanted to sustain the skeptical claim that we cannot justify metaphysical claims about things in themselves, hence that we cannot gain metaphysical knowledge about the existence of God, the immortality of the soul, the beginning of time, and the least parts of matter. He wanted to achieve this result in a more theoretically satisfying manner than had skeptical authors. Doing so would also allow him to curb certain forms of skeptical empiricism, by showing that we cannot disprove, or rule out as unintelligible, human freedom, an afterlife, or divine providence. The article ends by considering the retrospective rereadings of the Deduction by Hermann Cohen and P. F. Strawson, concluding that these rereadings force Kant's text into an alien mold, thereby diminishing its philosophical value as a work with its own distinctive aims and methods. (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)

Recent publications (Henrich, Seeberg) claim that Kant has been profoundly influenced by contemporary publications on juridical deductions. I try to show, that this cannot be right. The introductory note of the “Transcendental Deduction” (Critique of Pure Reason A 84) poses two questions: “quid facti?” and “quid juris?”. The first is answered by the demonstration of the possibility of relations between pure concepts and pure intuition und sensations, the second by the implicit refutation of David Hume. Kant and his interpreters sustain (...) the possibility of using juridical concepts, that are neither related to real juridical facts nor are only metaphers, but have a special philosophical signification. But what should that be? (shrink)

In The Philosophical Criticism, Alois Riehl developed a realistic interpretation of Kant’s transcendental idealism based on his theory of space and time. In doing so, more than 100 years ago, he formulated an interpretation of the relation between the thing in itself and appearances that is discussed in current research as the metaphysical „dual aspect“ interpretation, although it is rarely attributed to Riehl. To reconstruct Riehl’s position, the research results of comparative studies on Moritz Schlick are systematically extended and applied (...) to the current debate on Kant’s transcendental idealism.
