Kant’s denial that psychology is a properly so-called natural science, owing to the lack of application of mathematics to inner sense, has garnered a great deal of attention from scholars. Although the interpretations of this claim are diverse, commentators by and large fail to ground their views on an account of Kant’s conception of applied mathematics. In this article, I develop such an account, according to which the application of mathematics to a natural science requires both a mathematical representation and (...) a metaphysical validation for the positive use of this representation to achieve a priori knowledge about nature. The second condition—that of metaphysical validation—has been overlooked in the literature. I show that psychology’s falling short of natural scientific propriety consists not in our lacking sufficient mathematical tools for the representation of inner states, according to Kant. After all, we can represent the mere temporality of inner states with the line and their intensities with numbers. Rather, the problem is that metaphysics does not validate the further use of such mathematical entities for the achievement of a priori knowledge about inner phenomena. (shrink)

Kant is said to be the first to distinguish between consciousness of oneself as the subject of one’s experiences and consciousness of oneself as an object, which he calls transcendental and empirical apperception, respectively. Of these, it is empirical apperception that is meant to enable consciousness of any empirical features of oneself; what this amounts to, however, continues to puzzle interpreters. I argue that a key to understanding what empirical apperception consists in is Kant’s claim that each type of apperception (...) corresponds to a distinct type of unity of apperception—that is, a distinct way in which representations can be related for a subject. Whereas transcendental unity of apperception requires that representations be actively combined by the understanding, empirical unity of apperception obtains when representations are passively combined by the reproductive imagination. In light of this, I develop a novel account of Kant’s two types of apperception, according to which they correspond to a cognitive subject’s consciousness of two essential aspects of herself—namely, her spontaneity and receptivity.

ABSTRACT Kant famously claims that we have all freely chosen evil. This paper offers a novel account of the much-debated justification for this claim. I reconstruct Kant’s argument from his affirmation that we all have a price – we can all succumb to temptation. I argue that this follows a priori from a theoretical principle of the Critique of Pure Reason, namely that all empirical powers have a finite, changeable degree, an intensive magnitude. Because of this, our reason can always (...) be overpowered by sensible inclinations. Kant moreover holds that this necessary feature of our moral psychology should not have been the case: We ought to instead be like the divine human being, for whom the moral law yields a greater incentive than any possible temptation. On Kant’s view, we are thus responsible for having a price, and the synthetic a priori fact that we do proves that we each made an initial choice of evil. (shrink)

Charles Sanders Peirce was acknowledged by William James as the founder of pragmatism; however, while James’ appreciation for psychology is well taken into account in his philosophy, the role that psychological inquiry played in Peirce’s thought remains largely unexplored. Few excellent studies indicate Peirce as the first American experimental psychologist (Cadwallader 1974, 1975; Fisch 1986) and as the first to perform a truly modern experiment in psycho-physics (Hacking 1988). Nonetheless, Peirce’s commitment to psycho-physics fails to be fully integrated with the (...) broader project of his philosophy. This integration is crucial to gain a better understanding of the complexity of Peirce’s system of thought and of his position in the psychologistic-antipsychologistic divide. On the logical side, making Peirce’s position on psychology explicit leads to investigating his material logic; on the psychological side, Peirce’s scientific approach to psychology has its theoretical foundation in Kant and further marks the distinction between Peirce’s pragmatism and James’.

Since his Metaphysische Anfangsgründe der Naturwissenschaft was first published in 1786, controversy has surrounded Immanuel Kant’s conception of matter. In particular, the justification for both his dynamical theory of matter and the related dismissal of mechanical philosophy are obscure. In this paper, I address these longstanding issues and establish that Kant’s dynamism rests upon Leibnizian, metaphysical commitments held by Kant from his early pre-Critical texts on natural philosophy to his major critical works. I demonstrate that, throughout his corpus and inspired (...) by Leibniz, Kant endorses the a priori law of continuity of alteration as a truth of metaphysics, according to which all alterations in experience must occur gradually through all intervening degrees. The principle thus legislates against mechanical philosophy’s absolutely impenetrable atoms, as they would would involve instantaneous changes of velocity in impact. This reveals the metaphysical incoherencies in mechanical philosophy and leaves Kant’s own dynamical theory of matter, grounded on material forces, as the only viable approach to physical explanation. Subsequently, I demonstrate that Kant nevertheless made conceptual space in his system for the theoretical consideration of mechanical explanations, which makes manifest one of the positive roles that the faculty of reason can play with respect to natural science.

Kant is well known for his restrictive conception of proper science. In the present paper I will try to explain why Kant adopted this conception. I will identify three core conditions which Kant thinks a proper science must satisfy: systematicity, objective grounding, and apodictic certainty. These conditions conform to conditions codified in the Classical Model of Science. Kant’s infamous claim that any proper natural science must be mathematical should be understood on the basis of these conditions. In order to substantiate (...) this reading, I will show that only in this way it can be explained why Kant thought (1) that mathematics has a particular foundational function with respect to the natural sciences and (2) as such secures their scientific status.

According to Kant each person has an empirical character, which is ultimately grounded in one’s free choice. The popular Causal Laws interpretation of empirical character holds that it consists of the causal laws governing our psychology. I argue that this reading has difficulties explaining moral change, the ‘gradual reformation’ of our empirical character: Causal laws cannot change and hence cannot be gradually reformed. I propose an alternative Causal Powers interpretation of empirical character, where our empirical character consists of our mind’s (...) causal powers. The resulting picture of empirical character allows for moral change and Kantian weakness of will. (shrink)

Consider the laws of nature—the laws of physics, for example. One familiar philosophical question about laws is this: what is it to be a law of nature? More specifically, is a law of nature a regularity, or a generalization stating a regularity? Or is it something else? Another philosophical question is: how, and to what extent, can we have knowledge of the laws of nature? I am interested here in Kant's answers to these questions, and their place within his broader (...) theoretical philosophy during the period spanning from the first to the third Critique. (shrink)

Hegel seeks to overturn Kant's conclusion that our knowledge is restricted, or that we cannot have knowledge of things as they are in themselves. Understanding this Hegelian ambition requires distinguishing two Kantian characterizations of our epistemic limits: First, we can have knowledge only within the "bounds of experience". Second, we cannot have knowledge of objects that would be accessible only to a divine intellectual intuition, even though the faculty of reason requires us to conceive of such objects. Hegel aims to (...) drive a wedge between these two characterizations, showing that we can have knowledge beyond Kant's bounds of experience, yet without need of divine intuition. And attention to such knowledge is supposed to show that we have no legitimate need to even conceive of divine intuition and its objects - and no need to conclude that our own knowledge is restricted by comparison, or that we cannot know things as they are in themselves. I focus here on the initial case Hegel uses to introduce this extended argument strategy: we can have more knowledge of natural kinds and laws than would be allowed by Kant's bounds of experience.

This article advocates a new interpretation ofinner experience– the experience that one has of one’s empirical-psychological features ‘from within’ – in Kant. It argues that for Kant inner experience is the empirical cognition of mental states, but not that of a persistent mental substance. The schema of persistence is thereby substituted with the regulative idea of the soul. This view is shown to be superior to two opposed interpretations: the parity view that regards inner experience as empirical cognition of a (...) mental object on a par with outer experience and the disparity view that denies altogether that inner experience is empirical cognition.

This paper shows why Kant's critique of empirical psychology should not be read as a scathing criticism of quantitative scientific psychology, but has valuable lessons to teach in support of it. By analysing Kant's alleged objections in the light of his critical theory of cognition, it provides a fresh look at the problem of quantifying first-person experiences, such as emotions and sense-perceptions. An in-depth discussion of applying the mathematical principles, which are defined in the Critique of Pure Reason as the (...) constitutive conditions for mathematical-numerical experience in general, to inner sense will demonstrate why it is in principle possible to justify a quantitative structure of psychological judgments on the grounds of Kant's critical thinking. In conclusion, it will propose how Kant's critique could be used in a constructive way to develop first steps towards a transcendental foundation of psychological knowledge. (shrink)

In his Metaphysische Anfangsgründe der Naturwissenschaft, Kant claims that chemistry is a science, but not a proper science (like physics), because it does not adequately allow for the application of mathematics to its objects. This paper argues that the application of mathematics to a proper science is best thought of as depending upon a coordination between mathematically constructible concepts and those of the science. In physics, the proper science that exhausts the a priori knowledge of objects of the outer sense, (...) only motions and concepts reducible to motions can be legitimately coordinated with mathematical constructions. Since chemistry can neither achieve its own a priori principles of coordination nor be reduced to the coordinated doctrine of motion, it is a merely improper science. (shrink)

One of Kant’s central tenets concerning the human sciences is the claim that one need not, and should not, use a physiological vocabulary if one studies human cognitions, feelings, desires, and actions from the point of view of his ‘pragmatic’ anthropology. The claim is well known, but the arguments Kant advances for it have not been closely discussed. I argue against misguided interpretations of the claim, and I present his actual reasons in favor of it. Contemporary critics of a ‘physiological (...) anthropology’ reject physiological explanations of mental states as more or less epistemologically dubious. Kant does not favor such ignorance claims—and this is for the good, since none of these claims was sufficiently justified at that time. Instead, he develops an original irrelevance thesis concerning the empirical knowledge of the physiological basis of the mind. His arguments for this claim derive from his original and, up to now, little understood criticism of a certain conception of pragmatic history, related to his anthropological insights concerning our ability to create new rules of action, the social dynamics of human action, and the relative inconstancy of human nature. The irrelevance thesis also changes his views of the goal and methodology of anthropology. Kant thereby argues for a distinctive approach in quest for a general ‘science of man’.Keywords: Anthropology; Psychology; Psychophysiological explanations; Pragmatic history; Action explanation; Human nature.

We argue that Kant’s views about consciousness, the mind-body problem, and the status of psychology as a science all differ drastically from the way in which these topics are conjoined in present debates about the prominent idea of a science of consciousness. Kant did never use the concept of consciousness in the now dominant sense of phenomenal qualia; his discussions of the mind-body problem center not on the reducibility of mental properties but of substances; and his views about the possibility (...) of psychology as a science did not employ the requirement of a mechanistic explanation, but of quantification of phenomena. This shows strikingly how deeply philosophical problems and conceptions can change even if they look similar on the surface. (shrink)

Starting with Kant’s doubts about psychology as a natural science capable of explaining human behavior, several alternative attempts to conceive of human life, culture and history are examined. Kant proposes an anthropology that will be a commonly useful human science rather than a universally valid natural science. This anthropology relates to philosophy as a mode of world-cognition. Special attention is given to how Kant’s theory of right can help define our appropriate place in a communal world. The different ways in (...) which Wilhelm Dilthey and Hermann Cohen respond to Kant’s idea of legitimate appropriation are also considered. The various tasks that descriptive elucidation, explanation, reflective understanding, characterization and interpretation can perform for the human and cultural sciences are examined throughout the essay.Keywords: Appropriation; Hermann Cohen; Culture; Wilhelm Dilthey; Human sciences; Immanuel.
