In this monograph, I argue that the received conception of the aim and results of Kant’s Paralogisms must be revised in light of a proper understanding of the rational psychology that is the most proximate target of Kant’s attack. Introduction. Chapter 1: The Marriage of Reason and Experience: Wolff’s Rational Psychology. Chapter 2: From Wolff to Kant: Rational Psychology in the 18th Century. Chapter 3: The Divorce of Reason and Experience: Pure Rational Psychology and the Substantiality of the Soul. Chapter (...) 4: The Achilles and the Tortoise: The Simplicity of the Soul. Chapter 5: The Aeneas Argument: The Personality of the Soul. Chapter 6: Cartesian Questions: Idealism and the Illusion of the Soul. Chapter 7: Kant’s Rational Psychology: Fundamental Forces and the Regulative Use of the Idea of the Soul. Conclusion. (shrink)

In attempts to come to grips with Kant’s thought, the influence of the philosophy of Christian Wolff (1679-1754) is often neglected. In this paper, I consider three topics in Kant’s philosophy of mind, broadly construed, where Wolff’s influence is particularly visible: consciousness, self-consciousness, and psychology. I argue that we can better understand Kant’s particular arguments and positions within this context, but also gain a more accurate sense of which aspects of Kant’s accounts derive from the antecedent traditions and which constitute (...) genuine philosophical innovations.

This paper considers how Descartes's and Hume's sceptical challenges were appropriated by Christian Wolff and Johann Nicolaus Tetens specifically in the context of projects related to Kant's in the transcendental deduction. Wolff introduces Descartes's dream hypothesis as an obstacle to his account of the truth of propositions, or logical truth, which he identifies with the 'possibility' of empirical concepts. Tetens explicitly takes Hume's account of our idea of causality to be a challenge to the `reality' of transcendent concepts in general, (...) a challenge he addresses by locating the source of this concept in the understanding rather than in the imagination. After considering this background, I turn to Kant's deployment of apparently traditional sceptical concerns at the outset of the transcendental deduction and argue that he does not there intend to introduce a global sceptical challenge and, accordingly, that there are historical grounds for doubting that the transcendental deduction is intended as an anti-sceptical argument.

While there is good reason to think that Mendelssohn's Morgenstunden targets some of the key claims of Kant’s first Critique, this criticism has yet to be considered in the appropriate context or presented in all of its systematic detail. I show that far from being an isolated assault, Mendelssohn’s attack in the Morgenstunden is a continuation and development of his earlier criticism of Kant’s idealism as presented in the Inaugural Dissertation. I also show that Mendelssohn’s objection was more influential on (...) Kant than has previously been suspected; not only did Kant respond to it in a brief review and a set of remarks published along with a disciple’s examination of Mendelssohn’s text but, as I will suggest, Kant’s Refutation of Idealism is intended (at least in part) to undermine the Cartesian starting-point Mendelssohn had presumed throughout his campaign against Kantian idealism.

Morning Hours is the only available English translation of Morgenstunden by Moses Mendelssohn, the foremost Jewish thinker of the German Enlightenment. Published six months before Mendelssohn's death on January 4, 1786, Morning Hours is the most sustained presentation of his mature epistemological and metaphysical views, all elaborated in the service of presenting his son with proofs for the existence of God. But Morning Hours is much more than a theoretical treatise. It also plays a central role in the drama of (...) the Pantheismusstreit, Mendelssohn's "dispute" with F. H. Jacobi over the nature and scope of Lessing's attitude toward Spinoza and "pantheism". In Morning Hours Mendelssohn attempts to set the record straight regarding his beloved Lessing in this connection, not least by demonstrating the absence of any practical difference between theism and a "purified pantheism".

In this paper, I challenge the assumption that Kant’s Third Paralogism has to do, first and foremost, with the question of personal identity.

I consider Kant's criticism of rational psychology in the Paralogisms of Pure Reason in light of his German predecessors. I first present Wolff's foundational account of metaphysical psychology with the result that Wolff's rational psychology is not comfortably characterized as a naïvely rationalist psychology. I then turn to the reception of Wolff's account among later German metaphysicians, and show that the same claim of a dependence of rational upon empirical psychology is found in the publications and lectures of Kant's pre-Critical (...) period. Considering the Paralogisms in this context reveals Kant's conception of rational psychology to be distinctly novel and has important consequences in shifting the argumentative focus of the chapter.

In what follows, I will detail Kant's criticism of the Leibnizian conception of mind as it is presented in key chapters of the Kritik der reinen Vernunft . Approaching Kant with such a focus goes against the current predominant in contemporary Kant scholarship. Kant's engagement with Leibniz in the KrV is often taken as limited to the refutation of the latter's relational theory of space and time in the Aesthetic and the general criticism presented in the Amphiboly chapter, inasmuch as (...) Kant is taken to be primarily concerned with addressing empiricist opponents (a focus particularly evident in the English-language commentary). In addition, the argument against rational psychology in the Paralogisms is taken as challenging an essentially Cartesian position. The first two chapters of this project will introduce the Leibnizian conception of the mind, contrasting it with its Cartesian predecessor, and consider the career of the Leibnizian conception in the schools of 18th century Germany. As I will show, it was the Leibnizian conception of mind that held sway, despite scattered challenges, and that would have primarily been on Kant's mind when he turned to consider the extravagant claims of metaphysical psychology. In chapters 3-5, I turn to Kant's criticism of this conception as presented in the Transcendental Analytic of the KrV . There, I show how the subjective and objective deductions, in addition to the Amphiboly chapter, all address the Leibnizian claim of a parallelism between the investigations of the mental and the physical. In chapters 6-8, I consider the case against the Leibnizian conception of mind as presented in the Transcendental Dialectic, claiming that the doctrine of transcendental illusion plays an important (though largely ignored) role in explaining the grounds of the Leibnizian conception as it is transmitted in the rational psychology of Wolff, Baumgarten, Crusius, and Kant himself in the 1770's. Moreover, I argue that the limits Kant sets to empirical psychology are consistent with his criticism of the Leibnizian conception of mind, and, significantly, are motivated by deeper practical concerns.

In the Anthropology, Kant wonders whether the genius or the individual possessing perfected judgment has contributed more to the advance of culture. In the KU, Kant answers this question definitively on the side of those with perfected judgment. Nevertheless, occurring as it does in §50 of the KU, immediately after Kant’s celebration of the genius in §49, this only raises more questions. Kant rejects the genius in favour of the individual of taste as an advancer of culture, yet under what (...) conditions could the genius contribute? And, what threat does the genius really pose to this advance, other than that of penning simple nonsense? This essay attempts to answer these questions, using key texts and overlooked Reflexionen, all of which nest Kant’s concern for the genius in the associated risks of fanaticism. I conclude that, given certain conditions, the genius can contribute in a unique manner to the advance of culture. (shrink)
