In the Transcendental Dialectic, Kant searched for a universal concept of reason different from the understanding and offered the short formula “the faculty of principles”. I will argue that this is only one and not the most pertinent and general mark of the concept of reason. There are more compelling short expressions in Kant’s Reflexionen, the third Critique and/or in the reception of Kant’s works: “the faculty of ideas” or reason in the narrower sense. The latter narrows down the logical (...) sphere of the concept of rational faculties, and the former contains reason’s most basic mark: ideas. The first part of this article will focus on preliminary remarks on Kant’s philosophical methodology and conceptual analysis. The second part will analyze the division of the logical sphere of the concept of reason by nine necessary and coherent marks. These marks are centered around the concept of ideas, which allows for an ideas-first understanding of reason and preference for the formulas the faculty of ideas and reason in the narrower sense. The article will end with an “imperfect definition” of reason based on those nine marks. (shrink)

To judge by the title, one would expect that interpretations of the Critique of Pure Reason would prioritize the division of the book most about reason and its critique: The Transcendental Dialectic. But the Dialectic is surprisingly secondary in the most established interpretive approaches. This article argues as follows: There is a problem that contributes to explaining the lack of popularity: The problem of how arguments really based in the Dialectic itself really promise to ground a broader project in theoretical (...) philosophy, of the scope of the Critique. But the problem can be solved: One aim important in the critique is critical argument against rationalist metaphysics. The Dialectic must play a central role in such critique, given a difficulty concerning begging the question. The positive claims of the Dialectic, about reason and the unconditioned, are necessary for such an argument, and the Dialectic gives them enough defense for that purpose. Finally, there are reasons to take seriously Kant’s promises that the Antinomy of the Dialectic can support the weight in such an argument, without begging the question. The article concludes that a Dialectic-first approach to the Critique is viable and worth further development. (shrink)
