Kant’s claim in the Subjective Deduction that we have multiple fundamental mental powers appears to be susceptible to some a priori metaphysical arguments made against multiple fundamental mental powers by Christian Wolff who held that these powers would violate the unity of thought and entail that the soul is an extended composite. I argue, however, that in the Second Paralogism and his lectures on metaphysics, Kant provides arguments that overcome these objections by showing that it is possible that a composite (...) could ground the unity of thought, that properties are powers and therefore the soul could possess multiple powers, and the soul is a thing in itself so it cannot be an extended composite. These arguments lend additional support to the attribution of multiple mental powers to us in the Subjective Deduction. (shrink)

On the reading of Kant's resolutions of the first two antinomies advanced here, Kant not only denies that the empirical world has a ground floor of empirical objects lacking proper parts in the resolution of the second antinomy, but he also denies that it has a ceiling consisting in a composite whole enclosing all other empirical objects in the resolution of the first antinomy. Indeed, the order of explanation in the first antinomy runs from wholes to the proper parts they (...) spatially enclose, whereas the order of explanation runs in the opposite direction in the second antinomy. But this appears to involve viciously circular explanation, and hence to generate the problem of circular conditioning. Working out a solution to this problem involves closer investigation of Kant's account of real conditioning relations, and how these relations are connected to the structure of space and time.

This paper shows how reflection on habit leads in nineteenth-century French philosophy to Henri Bergson’s idea of duration in 1888 as a non-quantifiable dimension irreducible to time as measured by clocks. Historically, I show how Albert Lemoine’s 1875 L’habitude et l’instinct was crucial, since he holds – in a way that is both Ravaissonian and Bergsonian avant la lettre – that for the being capable of habit, the three elements of time are fused together. For that habituated being, Lemoine claims, (...) it is not true to say that the past is no longer, nor even that the future is not yet. This historical link between Ravaisson and Bergson, however, only sharpens the philosophical question of how a dynamic conception of habit involves and requires a conception of real duration, of a temporality more original than clock-time, and, conversely, of how reflection on duration prior to clock-time involves a notion of habit. With reference to the work of Gilles Deleuze, the paper concludes by showing that there is an internal connection between these two grand philosophical themes of nineteenth- and then twentieth-century French thought: habit and time.

RésuméLa critique kantienne de la psychologie rationnelle est une expérience de pensée visant ni un individu ni une école, mais une tendance de la raison humaine à « hypostasier » la condition intellectuelle suprême d'une connaissance quelconque (le « Je pense ») en connaissance du « moi ». Cette tendance implique une circularité qui est également la cible des critiques transcendantales bien plus familières qui visent Locke et Hume. De même qu'un nouveau type de cercle (dit « de niveau »), (...) cet article propose une conception des arguments transcendantaux différente de celle présupposée dans la plupart des débats contemporains sur l'empirisme, le naturalisme et le fondationnalisme cartésien.

In the Appendix to the Transcendental Dialectic, Kant formulates teleological principles, or rather ideas, and explicates them referring to concrete examples of natural science such as chemistry, astronomy, biology, empirical psychology, and physical geography. Despite the increasing interest in the systematic relevance of the Appendix to the Transcendental Dialectic and its importance for Kant’s conception of natural science, the numerous historical sources for the regulative use of reason have not yet been investigated. One that is very central is Maupertuis’ principle (...) of least action. In 1781, Kant transformed teleology into heuristics and methodology, but in doing so, he partially develops a teleology which was disqualified by Maupertuis because its starting point lies in the construction of animals or plants, the structure of the earth, and the immensity of the celestial bodies. Based on Maupertuis’ principle of action, it can be shown that the Appendix forms a systematic interface between Universal Natural History and Theory of the Heavens and Critique of Judgement which allows the reconstruction of Kant’s regulative use of reason and its specific status in the context of natural science and his critical appraisal of Maupertuis.

Hegel’sLogicargues in a manner that is supposed to support a systematic philosophy. But it is difficult to explain how such a systematic argument is supposed to work. For answers, I look to the key transition from the Doctrine of Essence to the Doctrine of the Concept. Here we find discussions of both Spinozist and Kantian systems of philosophy: both are supposed to be helpful, and yet also to be lacking in instructive ways. So the initial hope is that these comparisons (...) can help us to understand Hegel’s own systematic argument, and what it means to transition from an objective to a ‘Subjective Logic’. But the comparisons bring additional difficulties. First, to defend a comprehensive system involves refuting rivals, and the discussion of Spinoza demonstrates that refutation is difficult. Second, it is hard to see how any argument for Hegel’s system could be akin to those in Spinoza and Kant given the extent of the differences between them. I argue that the best way to deal with these difficulties is to explain the systematic argument of theLogicas modelled on the Transcendental Dialectic of Kant’s firstCritique. (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)
