Kant: Rational Psychology

These comments are my contribution to the author-meets-critics session on Katharina Kraus' recently published Kant on Self-Knowledge and Self-Formation, at the APA Pacific meeting. In my comments, I challenge Kraus' characterization of my fictionalism concerning the idea of the soul, and contend for the importance of transcendental illusion in that idea's function of guiding the empirical investigation of inner appearances.

Since the classic works by Castañeda, Perry and Lewis, de se thoughts have been described as thoughts about oneself ‘as oneself’. In recent years, various theoretical perspectives have gained ground, and even if the transcendental system does not seem to contemplate an explicit articulation of de se thoughts, apparently a few features of transcendental apperception and I think do anticipate a few points in Perry and Recanati’s claims on the so-called implicit de se thoughts in the specific terms of Transcendentalism.

: According to Kant, the arguments of rational psychology are formal fallacies that he calls transcendental paralogisms. It remains heavily debated whether there actually is any formal error in the inferences Kant presents: according to Grier and Allison, they are deductively invalid syllogisms, whereas Bennett, Ameriks, and Van Cleve deny that they are formal fallacies. I advance an interpretation that reconciles these extremes: transcendental paralogisms are sound in general logic but constitute formal fallacies in transcendental logic. By formalising the paralogistic (...) inference, I will pinpoint the error as an illegitimate existential presupposition. Since - unlike transcendental logic - general logic abstracts from all objects, this error can only be detected in transcendental logic. (shrink)

This paper takes issue with the widespread view that Kant rejects epistemic phenomenalism. According to epistemic phenomenalism, only cognition of states of one’s own mind can be certain, while cognition of outer objects is necessarily uncertain. I argue that Kant does not reject this view, but accepts a modified version of it. For, in contrast to traditional skeptics, he distinguishes between two kinds of outer objects and holds that we have direct access to outer appearances in our mind; but he (...) still considers objects outside our mind unknowable. This sheds new light on Kant’s refutation of idealism. (shrink)

Review of Béatrice Longuenesse, I, Me, Mine: Back to Kant, and Back Again. Oxford: Oxford University Press, 2017.

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.

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. (shrink)

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)

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 his pre-critical lectures on rational psychology, Kant employs an argument from the I to the transcendental freedom of the soul. In the (A-edition of the) first Critique, he distances himself from rational psychology, and instead offers four paralogisms of this doctrine, insisting that ‘I think’ no longer licenses any inferences about a soul. Kant also comes alive to the possibility that we could be thinking mechanisms – rational beings, but not agents. These developments rob him of his pre-critical rationalist (...) argument for freedom. In the Groundwork, this is a serious problem; if we are not free, morality will be a phantasm for us. In Groundwork III, Kant attempts to overcome this by offering a new argument for our freedom, involving the standpoint of practical reason. In this paper, I detail these developments and present a practical and phenomenological reading of Kant’s approach in Groundwork III. I also venture a defence of this new argument. (shrink)

Available for the first time in English, this critical translation draws from the original seven Latin editions and Georg Friedrich Meier's 18th-century German translation. Together with a historical and philosophical introduction, extensive glossaries and notes, the text is supported by translations of Kant's elucidations and notes, Eberhard's insertions in the 1783 German edition and texts from the writings of Meier and Wolff. For scholars of Kant, the German Enlightenment and the history of metaphysics, Alexander Baumgarten's Metaphysics is an essential, authoritative (...) resource to a significant philosophical text.

In this paper, I explore both Kant's and Collingwood's accounts of themind-body problem. I discuss how both philosophers think that this problem arises and how it can be resolved. I start by discussing the similarities between the attempts of the two philosophers at solving philosophical problems through analysing the conceptual structures that make experience possible. I then turn to the differences between the views of the two philosophers, paying particular attention to Kant's claims that a combination of a natural (so-called (...) 'transcendental') illusion and commitment to a faulty philosophical framework (transcendental realism) give rise to philosophical problems such as the mind-body problem. I argue, ultimately, that Kant's account is more compelling than Collingwood's. This is because Collingwood's account can only explain the mind-body problem as arising because certain concepts conflict with each other and compete as explanations of the same phenomena. Kant's account, on the other hand, states that the problem arises as a result of both an inevitable illusion and a misapplication of concepts. Both philosophers claim that the problem is perennial but Kant's reason for claiming this is more convincing. (shrink)

One of the most widely accepted contemporary constraints on theories of self-knowledge is that they must account for the very different ways in which cognitive subjects know their own minds and the ways in which they know other minds. Through the influence of Peter Strawson, Kant is often taken to be an original source for this view. I argue that Kant is quite explicit in holding the opposite position. In a little discussed passage in the Paralogisms chapter, he argues that (...) cognitive subjects have no way of understanding the minds of others except by using their own minds as a model for others.

This work speaks about very special solution of the mind–body problem. This solution based on the so-called Principle of Co-existence stands out as one of the most interesting attempts at solving the mind–body problem. It states that substances can only exert a mutual influence on one another if they have something in common. This does not have to be a common property but rather, a binding relationship. Thus, substances co-exist when they remain bound by a common relationship, for instance, to (...) an external subject. The Principle of Co-existence played an extremely important role in Kant’s philosophy, not only since it provided a framework for solving the mind–body problem, but since it captured the very basis of its existence. The Principle found also reflection in the works of Kant’s successors, such as Fichte, Schelling, Hegel or Feuerbach. It had significant—though often hidden—repercussions on later philosophy of mind. The notion of force and the principle of its operation became key concepts in resolving the mind–body problem. As a result, philosophy of mind concentrated on the search for a principle explaining the occurrence of two complementary types of phenomena. This established a tradition which, to a greater or lesser extent, has survived to our day. (shrink)

This paper investigates the philosophy of the eighteenth-century German physicist Georg Christoph Lichtenberg (1742–1799), situating his views in the context of early-modern views of the self, and providing an interpretation and assessment of his remarks on self-consciousness and personal identity in his Waste Books. In these remarks, which include his famous observation that we are warranted only in saying “it thinks” rather than “I think,” Lichtenberg criticizes the rationalist metaphysics of the soul for confusing conceivability with cognizability and argues that (...) we cannot know ourselves to be a persisting substantial self on the basis of the observations of inner sense. We are justified only in claiming that the self is a series of interrelated conscious representations and sensations. Lichtenberg’s rejection of the substantial self in favor of this view of the self also leads him to conclude in other remarks that personal identity consists in the continuity of consciousness produced by memory regardless of the material basis upon which consciousness supervenes.

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.

: It is the aim of the following considerations to use Kantian epistemology to advance the current debate about the relation between mind and brain. First of all the naturalistic assumption that all mental phenomena are based on neuronal processes is called into question. Secondly it is shown that naturalism leads necessarily to an absurd constructivism that is very similar to Kant’s transcendental position, but which conflicts with naturalism’s empirical premise. In spite of the progress in brain research Kant’s transcendental (...) approach is still a promising attempt to treat philosophical problems, especially the problem about the relation between mind, brain and world.

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 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 article offers an explanation and analysis of Kant’s philosophy of religion. It starts with Kant’s criticisms of the ontological, cosmological, and physico-teleological arguments for the existence of God from the ’Critique of Pure Reason’. It then explains Kant’s moral arguments in the ’Critique of Practical Reason’ for the existence and nature of God and for humans’ personal immorality. Finally, it lays out the argument for the necessity of grace from Kant’s ’Religion within the Boundaries of Mere Reaso.'.

One of the principle aims of the B version of Kant’s transcendental deduction is to show how it is possible that the same “I think” can accompany all of my representations, which is a transcendental condition of the possibility of judgment. Contra interpreters such as A. Brook, I show that this “I think” is an a priori (reflected) self-consciousness; contra P. Keller, I show that this a priori self-consciousness is first and foremost a consciousness of one’s personal identity from a (...) first person point of view. (shrink)

his paper argues that the critical doctrine of the necessary unity of the thinking subject propounded in Kant’s Second Paralogism contains an idealist commitment to the metaphysically exceptional nature of the unifying activity of thought. Rather than rejecting Kant’s transcendental framework as necessarily idealist and antagonistic to the current projects of speculative materialism, it is argued that transcendental philosophy should remain an important ingredient of any contemporary metaphysics. The implicit metaphysical idealism of Kantian critical idealism, it is claimed, in the (...) end reveals speculative resources within the architecture of transcendental philosophy that can, if I am right, maintain the importance of the project of determining the epistemological legitimacy of metaphysical knowledge without reducing metaphysics to the subjective idealism of Kantian critical philosophy.

In this paper I examine the genesis of Kant’s conception of a realm of ends, arguing that Kant first started to think of morality in terms of striving to be a member of a realm of ends, understood as an ideal community, in the early 1760s, and that he was influenced in this by his encounter with the Swedish mystic Emanuel Swedenborg. In 1766 Kant published Dreams of a Spirit Seer, a commentary on Swedenborg’s magnum opus, Heavenly Secrets. Most commentators (...) take Kant’s attitude towards Swedenborg to have been entirely negative, and argue that, at the most, Kant’s encounter with him had a purely negative impact on Kant’s development, inducing him to reject certain of his early metaphysical positions. I argue, in contrast, that Swedenborg had a positive influence on Kant’s development, particularly on his ethics, for Kant’s conception of a realm of ends is modeled on Swedenborg’s conception of heaven as a community of spirits governed by moral laws.

I consider whether there is a plausible conception of personal identity that can accommodate the ‘Multiplicity Thesis’ (MT), the thesis that some ways of creating and deploying multiple distinct online personae can bring about the existence of multiple persons where before there was only one. I argue that an influential Kantian line of thought, according to which a person is a unified locus of rational agency, is well placed to accommodate the thesis. I set out such a line of thought (...) as developed by Carol Rovane, and consider the conditions that would have to be in place for the possibility identified by MT to be realised. Finally I briefly consider the prospects for MT according to neo-Lockean and animalist views of personhood. (shrink)

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)

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

Melnick interprets the Kantian self from the first-person perspective as real abiding intellectual action. It unfolds in time but does not arise in inner or outer attending. Hence, it is neither a noumenal entity nor Kantian intuitable substance. Melnick thinks that his interpretation not only clarifies Kant’s arguments in the Paralogisms of the first Critique, but also illuminates Kant’s positive theory of self.Melnick argues that a thought is inchoate, unformed, and unsettled until the thinking self as intellectual marshaling action brings (...) it into focus and “coalesces” around it a series of related but out-of-focus thoughts ready to replace the focal thought if necessary. This marshaling action is temporal because it shifts/adjusts progressive attending but cannot be intuited in time. Its shifting/adjusting constitutes its only reality, for it would have to be in objective time if it were intrinsically real, which Kant’s transcendental idealism does not allow.As intellectual marshaling action, the thinking self cannot know itself as simple substantial entity. Instead, it knows itself as always-subject-and-never-predicate because it is constant and never swallowed up by particular thoughts, and as indivisible because its self-awareness as marshaling action in a whole thought is not the sum of its. (shrink)

I argue that Kant's Critique of Pure Reason offers a positive metaphysical account of the thinking self. Previous interpreters have overlooked this account, I believe, because they have held that any metaphysical view of the self would be incompatible with both Kant's insistence on the limitations of cognition and with his project in the Paralogisms. Closer examination, however, shows that neither of those aspects of the Critique precludes a metaphysical account of the self, and that other aspects (namely, the structure (...) of Kant's overall project and the commitments of his claims in the Transcendental Deduction) require such an account. Drawing on a principle of 'effect-relative composition,' I argue that Kant's self is neither an activity, a form, nor a representation, but instead an individual constituted by the thing or things that bring about the unity of a course of experience.

In the part of the first Critique known as “The Paralogisms of Pure Reason” Kant seeks to explain how even the most acute metaphysicians could have arrived, through speculation, at the ruefully dogmatic conclusion that the self (understood as the subject of thoughts or "thinking I") is a substance. His diagnosis has two components: first, the positing of the phenomenon of “Transcendental Illusion”—an illusion, modelled on but distinct from, optical illusion--that predisposes human beings to accept as sound--and as known to (...) sound--certain in fact flawed arguments for substantive theses about the nature of the self; second, the identification of the fallacy we commit when we succumb to this illusion. It is explained how these two elements combine to produce a central instance of (what Kant sees as) dogmatic speculative metaphysics, namely, the doctrine that the self is a substance in the sense of a necessarily non-inhering subject of inherence. It is argued that Kant has a novel, ingenious, and even somewhat plausible account of the route by which the rational psychologist arrives--or might arrive--at this view, an account that involves identifying a rather deep-rooted confusion about the very nature of conceivability.

[1] Experience is a real concrete phenomenon. The existence of experience entails the existence of a subject of experience. Therefore subjects of experience are concretely real. [2] The existence of a subject of experience in the lived present or living moment of experience, e.g. the period of time in which the grasping of a thought occurs, provably involves the existence of singleness or unity of an unsurpassably strong kind. The singleness or unity in question is a metaphysically real, concrete entity. (...) So if thoughts, or any experiences at all, really do occur or exist – and they do – then there exist entities that are genuine, concrete, metaphysical unities of an unsurpassable sort. [3] There is a metaphysically irreproachable sense in which we may – must – take these unsurpassable metaphysical unities to be themselves subjects of experience, although we may also take them to be thoughts or experiences. If so, there is a sound argument to the conclusion of the 2nd Paralogism. [4] Perhaps and are not in the final analysis distinct. Perhaps Kant is right, in his 1772 letter to Herz, that ‘the thinking or the existence of the thought and the existence of my own self are one and the same’. (shrink)

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 the second half of the 18th century the voices criticizing the concept of simple substances as proposed by Leibniz and Wolff became increasingly louder. In response, Kant altered his theory of substances as first proposed in the 1750s. So for example, while his notion of substance in the Monadologia physica is simple and not merely in space, but fills space entirely, the Kantian position in the 1760s and early 1770s is quite different. This essay examines the solution Kant offers (...) in his Inaugural Dissertation for the problems raised by critics of simple substances. It shows how Kant removes substance from space and consequently from the empirical world and makes it into a concept of the understanding which leads to the knowledge of simple substances by employment of the pure understanding.

This previously unpublished text of Michel Henry’s was written during the preparation of his first major work published in 1963: The Essence of Manifestation. Being devoted to the philosophy of Immanuel Kant, this extensive text could be as well integrated in the above mentioned book, namely in the context where the author criticizes the ontological monism privileged by the strong tradition of German philosophy, from Jacob Boehme and Kant to Heidegger. Starting from the topic of self-knowledge, this text focuses on (...) an internal division of Being, namely on the separation between consciousness and existence, an opposition that will take the form of a phenomenological distance. The author argues thus that the above mentioned German philosophical tradition is not able to grasp in its primordial nature the essence of the self, covered by the representation. (shrink)

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)
