Kant: Rational Psychology

This seminal contribution to Kant studies, originally published in 1982, was the first to present a thorough survey and evaluation of Kant's theory of mind. Ameriks focuses on Kant's discussion of the Paralogisms in the Critique of Pure Reason, and examines how the themes raised there are treated in the rest of Kant's writings. Ameriks demonstrates that Kant developed a theory of mind that is much more rationalistic and defensible than most interpreters have allowed.

Jonathan Bennett's two interpretations of Kant's Third Paralogism are shown to be inadequate. The Third Paralogism attempts to show that rational psychology provides an inadequate basis for the application of the concepts of "personhood" and "substance". The criteria for the application of "personhood" and "substance" must be empirical, and in the case of "personhood" they are bodily criteria. These criteria are available to each of us but only upon pains of abandoning what Bennett calls the Cartesian basis, i.e. rational psychology.

Transcendental consciousness is described by Kant as 'the one single thing' in which 'as in the transcendental subject, our perceptions must be encountered.' The unity of that subject depends on intellectual functions. I argue that its singularity is just the same as that of Kant's pre-intellectual 'form' of spatiotemporal 'intuition.' This may seem excluded by Kant's claim that it is through intellect that 'space or time are first given as intuitions.' But while preintellectual form is insufficient for space and time (...) as distinct 'things,' it is sufficient for the constitution of a 'single thing' indifferently construable as both. Contrary to what are typically seen as the main differences between Kant and Hume on identity of 'self,' there is thus already a difference in play below the level of either's concern with the sorts of connections available for the combining, or illusion of combining, of manifolds of 'impressions' or 'ideas.'.

This paper assesses the role of the Refutation of Idealism within the Critique of Pure Reason, as well as its relation to the treatment of idealism in the First Edition and to transcendental idealism more generally. It is argued that the Refutation is consistent with the Fourth Paralogism and that it can be considered as an extension of the Transcendental Deduction. While the Deduction, considered on its own, constitutes a 'regressive argument', the Refutation allows us to turn the Transcendental Analytic (...) into a 'progressive argument' that proceeds by the synthetic method.

The role and place of transcendental psychology in Kant's Critique of Pure Reason has been a source of some contention. This work presents a detailed argument for restoring transcendental psychology to a central place in the interpretation of Kant's Analytic, in the process providing a detailed response to more "austere" analytic readings.

Kant's noncognitive argument based on practical reason claims that moral considerations alone suffice to justify the idea of personal immortality as a postulate. Some recent objections are considered here that have charged him with overstepping his own distinction between phenomenon and noumenon. After examining the arguments, Kant is exonerated of having violated his own principles. More troubling, however, is the peculiarity involved in postulating an infinite progression toward a goal whose attainment, by hypothesis, would undermine the very foundations of morality (...) (which for Kant always requires the agonistic condition of struggling to improve one's lower nature). It is argued that this paradox necessitates a reexamination of some tacit cultural presuppositions underlying Kant's conception of the soul. Finally, an examination is made of the thought of Kitarō Nishida, whose Zen Buddhist–inspired dialectic of the basho (logical "place") provides an alternative perspective from which to reconsider the postulate of immortality. Nishida, like Kant, rigorously maintains the phenomenonnoumenon distinction, yet his examination of ethics leads him to postulate an eventual sublation of the "soul" principle. It is concluded that Kant's postulate of immortality, while plausible enough on its own terms, is limited by a Western cultural bias and therefore fails in the end to be compelling. (shrink)

'the whole work is remarkably fresh, vivid and attractively written psychologists will be grateful that a work of this kind has been done ... by one who has the scholarship, science, and philosophical training that are requisite for the task' - Mind This renowned three-volume collection records chronologically the steps by which psychology developed from the time of the early Greek thinkers and the first writings on the nature of the mind, through to the 1920s and such modern preoccupations as (...) criminal and animal psychology. It is only in relatively recent times that psychology has been considered an empirical science independent of philosophy. Brett's account is thus concerned with the broadest definition of psychology, taking in such philosophical aspects as the relation of mind and body, thought processes, etc. For each period he gives an account of the state of the sciences which influenced psychology, the state of psychology itself, the influence psychology had on other areas, and the applications of psychological theories. Examining a huge range of figures, he describes their attitudes on fundamental questions and their contribution to the progress of the subject, as well as the history of the different methods of inquiry. The thinkers he discusses range from Aristotle, Democritus, Socrates, Plato, and Xenocrates to Proclus, the Arabian teachers, Magnus, Duns Scotus, and Ockham from Galileo, Descartes, Gassendi, and Cudworth to Locke, Berkeley, Condillac, and Kant from Reid, Stewart, Herbart, and Schopenhauer to Bain, Spencer, Mill and Darwin. Surprisingly clear and easy to read, Brett's account succeeds in illuminating the nature of psychology as well as its history. It remains a classic overview of the subject from its broad roots in philosophy through to the independent empirical science of the modern era. --a scarce work, rarely found as a complete set --a classic work - all historians of psychology and philosophy should have A History of Psychology.

The concept of the self is embedded in a web of relationships of other concepts and phenomena such as consciousness, self-consciousness, personal identity and the mind–body problem. The article follows the ontological and epistemological roles of the concept of selfconsciousness and the structural co-implication of consciousness and self-consciousness from Descartes and Locke to Kant and Sartre while delineating its subject matter from related inquiries into the relationship between the mind and the body, personal identity, and the question whether consciousness is (...) an irreducible reality sui generis or essentially a neurobiological entity. Over the course of its history, the modern self turns out to become an ever more elusive phenomenon, while its roles as a bearer of individual responsibility and as a subject of reflective endorsement of the truth become ever more pronounced.

Kant made a number of highly original discoveries about the mind - about its ability to synthesise a single, coherent representation of self and world, about the unity it must have to do so, and about the mind's awareness of itself and the semantic apparatus it uses to achieve this awareness. The past fifty years have seen intense activity in research on human cognition. Even so, Kant's discoveries have not been superseded, and some of them have not even been assimilated (...) into current thinking. That is particularly true of his work on unity and on the semantic apparatus of self-awareness. The first four chapters of this book present a comprehensive overview of Kant's model for non-specialists, an overview largely unencumbered by detailed exegesis. The work then offers a close study of five major discussions of the mind in the Critique of Pure Reason and Anthropology. (shrink)

Israel Gottlieb Canz’s Uberzeugender Beweiß, first published in 1741 and reprinted here in its second, expanded edition stands as his most influential discussion of the soul’s immortality, with one contemporary pronouncing it to be “one of the best [treatments of immortality] that we have.” In this text, Canz seeks to augment and supplement traditional Wolffian proofs by considering, first, the grounds for the soul’s immortality that are contained in its own nature and, second, the grounds for the same that are (...) found in God. In addition, Canz extends his treatment to include a detailed discussion of the souls of children and he offers speculations concerning the soul’s condition in the afterlife. On account of its systematic presentation and original argumentation, Canz’s Beweiß represents a key contribution to Leibniz-Wolffian rational psychology, and through the critical reaction it generated it would help shape the debate concerning the soul’s immortality for years after its original publication.

The dissertation analyzes Kant's arguments against Cartesian skepticism from the precritical period up to the "Reflexionen zum Idealismus" . It is argued that in the silent decade , the skeptical challenge leads Kant to reinterpret the foundation of his philosophy, namely, the distinction between appearances and things in themselves. Realizing the impossibility of refuting the skeptic through the identification of appearances with mental entities and the affirmation of the mind-independent existence of things in themselves as causes of the appearances , (...) Kant is forced to modify radically his notion of appearances in such a way as to make a new anti-skeptical argument possible. Thus, he no longer interprets appearances as mental entities, but as genuine, mind-independent objects. In this way, the skeptical challenge leads Kant to his mature notion of empirical realism, as presented in the 1781 Fourth Paralogism. ;The dissertation also shows that the mainstream evaluation of the arguments from the critical period needs to be revised. Some interpreters consider Kant's overall attempt to refute the skeptic ultimately unsatisfactory. Others are convinced that Kant manages to refute the skeptic only with the Second Edition argument, the Refutation of Idealism. The Fourth Paralogism---the argument that Kant presents in 1781, but drops in the Second Edition---is usually dismissed because of its alleged commitment to phenomenalism that makes it unable to serve as the foundation of the existence of a mind-independent world. In contrast with both groups, it is argued that Kant does have a powerful argument against the skeptic, which, however, is not to be found in the Refutation of Idealism or in its refinements in the "Reflexionen," but in a line of thought contained in the Fourth Paralogism, properly interpreted in a non-phenomenalistic way. The Refutation of Idealism, despite its intuitive appeal, ultimately fails and can be salvaged only if anti-skeptical resources are borrowed from the Fourth Paralogism. (shrink)

In 1747, Kant believed that the mind/body problem presupposed several false and interrelated assumptions that fell under the general view that the essential force of body is vis motrix, namely that bodies act only by causing changes of motion, that bodies can be acted upon only by being moved, and that souls and bodies do not share a common force. He argued in Thoughts on the True Estimation of Living Forces that the traditional vis motrix view, which was defended by (...) Wolff, appealed to an unexplanatory and metaphysically incoherent conception of force. ;Kant maintained that God acted to unify our world in such a way that all its finite substances possess a vis activa capable of producing motion in bodies and representations in souls. Unlike Leibniz's account of vis activa, Kant's account was compatible with the existence of transeunt or externally-directed forces. Indeed, Kant argued that every change in our world involves the exercise of a transeunt force. ;In Living Forces, Kant used these ideas to solve the mind/body problem. This study evaluates Kant's solution and traces his responses in later pre-critical texts to several acute difficulties. Chief among these difficulties was that his account of the "divine schema" of our world was incompatible with his metaphysical dualism: to exist in our world, Kant argued, all substances must possess attractive and repulsive forces, but attributing these forces to souls implied that they also possessed the same material nature as the physical monads out of which material bodies are composed. ;Kant did not recognize this problem until the early 1760s, and in the Dreams of a Spirit-Seer he maintained that it was insoluble. In the Meta-physik L1 lectures , Kant articulated a new understanding of the mind/body problem that centered on the idea that the body is an object of outer sense and the soul an object of inner sense. ;I conclude that, although his understanding of mind/body connectedness remained inadequate in the mid-1770s, Kant's struggles with this and related issues contributed to the development of systematic critical strictures on meta-physical reasoning and to the critical theory of inner sense.

Hume’s account of causation is often regarded a challenge Kant must overcome if the Critical philosophy is to be successful. But from Kant’s time to the present, Hume’s denial of our ability to cognize supersensible objects, a denial that relies heavily on his account of causation, has also been regarded as a forerunner to Kant’s critique of metaphysics. After identifying reasons for rejecting Wayne Waxman’s recent account of Kant’s debt to Hume, I present my own, more modest account of this (...) debt, an account that seeks to unite the two very different pictures of Kant’s relationship to Hume sketched above.

In this paper I propose to consider a certain set of notions in Kant as subsumable under a single notion – that of the soul’s intensity – as well as the possibility of a transcendental grounding of this notion within Kant ’s critical framework. First, I discuss what it means for Kant to attribute intensive magnitude to the soul, starting with his response to Mendelssohn where Kant introduces the soul’s intensity as a metaphysical notion immanent to the principles of rational (...) psychology. I show, however, that in Kant ’s counter-argument there occurs a subtle though crucial shift in perspective – from the soul’s substance to its powers. Then I move on to consider three fundamental variants upon the soul’s intensity – intensities of representation, of life, and of cognition – each governed, I argue, by the implied notions of measure of intensity and its balance. Also, I examine Kant ’s accounts of the life of a species and the necessity of sickness; of intensity of “enlightenment” in a society and the benefit of ignorance; and of sermon as a practical exertion of cognition’s intensity. Next, the aforementioned shift of emphasis allows me to demonstrate that the notion of the soul’s intensity can indeed be transcendentally justified by appealing to Kant ’s principle of the Anticipations of Perception. Finally, I conclude with an appendix on the possible connection of the soul’s intensity to Kant ’s aesthetics. (shrink)

James Van Cleve examines the main topics from Kant's Critique of Pure Reason, such as transcendental idealism, necessity and analyticity, space and time, substance and cause, noumena and things-in-themselves, problems of the self, and rational theology. He also discusses the relationship between Kant's thought and that of modern anti-realists, such as Putnam and Dummett. Because Van Cleve focuses upon specific problems rather than upon entire passages or sections of the Critique, he makes Kant's work more accessible to the serious student (...) and scholar. (shrink)

I will discuss Kant 's arguments in these section in three parts. In Part I, I will try to show how we can make sense of the obviously close relations in theme and content between the Refutation of Idealism and the two version of the Fourth Paralogism, as well as the second Postulate of Empirical Thought. This will serve as a kind of introduction, since on a cursory first reading, the connections might be far from apparent. In the process, I (...) will try to isolate a few basic. (shrink)

In this paper I argue, contrary to a widely influential account of Kant’s development in the “silent decade,” that key changes in his empirical and rational psychology throughout the 1770’s are traceable to changes in the scope he assigns to inner sense. Kant’s explicit inclusion of our access to the I or soul within the scope of inner sense in the early 1770’s (after its apparent exclusion in the Dissertation) yields a more robust empirical psychology. Given the Wolffian character of (...) Kant’s pre-Critical conception rational psychology, this in turn provides a firmer foundation for the rational cognition of the soul, as exemplified in Kant’s treatment in the ML1 notes. Even so, I contend that Kant’s eventual rejection of the pretenses of rational psychology to offer cognition of the soul likewise has its basis in his later exclusion of any access to the I from the scope of inner sense, which also reveals a previously unnoticed continuity between his pre-Critical and Critical conceptions of rational psychology.

Considered in light of the reader’s expectation of a thoroughgoing criticism of the pretensions of the rational psychologist, and of the wealth of discussions available in the broader 18th century context, which includes a variety of proofs that do not explicitly turn on the identification of the soul as a simple substance, Kant’s discussion of immortality in the Paralogisms falls lamentably short. However, outside of the Paralogisms (and the published works generally), Kant had much more to say about the arguments (...) for the soul’s immortality as he devoted considerable time to the topic throughout his career in his lectures on metaphysics. In fact, as I show in this paper, the student lecture notes prove to be an indispensable supplement to the treatment in the Paralogisms, not only for illuminating Kant’s criticism of the rational psychologist’s views on the immortality of the soul, but also in reconciling this criticism with Kant’s own positive claims regarding certain theoretical proofs of immortality.

Corey W. Dyck presents a new account of Kant's criticism of the rational investigation of the soul in his monumental Critique of Pure Reason, in light of its eighteenth-century German context. When characterizing the rational psychology that is Kant's target in the Paralogisms of Pure Reason chapter of the Critique commentators typically only refer to an approach to, and an account of, the soul found principally in the thought of Descartes and Leibniz. But Dyck argues that to do so is (...) to overlook the distinctive rational psychology developed by Christian Wolff, which emphasized the empirical foundation of any rational cognition of the soul, and which was widely influential among eighteenth-century German philosophers, including Kant. In this book, Dyck reveals how 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. In particular, he contends that Kant's criticism hinges upon exposing the illusory basis of the rational psychologist's claims inasmuch as he falls prey to the appearance of the soul as being given in inner experience. Moreover, Dyck demonstrates that significant light can be shed on Kant's discussion of the soul's substantiality, simplicity, personality, and existence by considering the Paralogisms in this historical context.Readership: Scholars and advanced students in history of philosophy, especially those working on Kant.

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.

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.

Der Aufsatz beschäftigt sich mit Kants Paralogismen der Kritik der reinen Vernunft. Im ersten Teil wird die These entwickelt, dass Kants Kritik an der rationalen Psychologie wesentlich auf der Behauptung beruht, dass etwas, das nur in der Zeit und nicht im Raum gegeben ist, nicht anhand des Begriffs der Substanz bestimmt werden kann. Im zweiten Teil wird gefragt, ob und wie das Ich als Begleitvorstellung wahrgenommen werden kann.
