Kant: Metaphysical Foundations of Natural Science

Kant's reasoning in his special metaphysics of nature is often opaque, and the character of his a priori foundation for Newtonian science is the subject of some controversy. Recent literature on the Metaphysical Foundations of Natural Science has fallen well short of consensus on the aims and reasoning in the work. Various of the doctrines and even the character of the reasoning in the Metaphysical Foundations have been taken to present insuperable obstacles to accepting Kant's claim to ground Newtonian science. (...) Gordon Brittan and Gerd Buchdahl, amongst others, have argued that Kant's stated aims in this case are not to be taken at face value, and that prior ontological commitments play a hidden but central role in Kant's special metaphysics. ;Michael Friedman has shown how Kant's stated aims can be taken seriously with his ingenious reconstruction of the Metaphysical Foundations as a demonstration of the a priori basis for our thinking bodies to be in true motion and in absolute space. However, Friedman does not address the issue of matter theory--despite the importance of the issue to Kant. I argue that a strict reading of both the stated aims and doctrines of the Metaphysical Foundations is possible, since much of Kant's reasoning about the empirical concept of matter can be explained by his views on how the construction of empirical concepts is possible. ;Kant's quasi-mathematical constructions are pivotal in Friedman's interpretation. Constructibility is Kant's criterion of acceptability for the concepts of natural science. Yet Kant notoriously fails to construct the dynamical concept of matter, and accepts this failure with an equally notorious complacency. I argue that Kant's criteria of empirical concept construction, apart from any prior ontological commitments, are enough to generate his views on matter. Kant's failure to construct the requisite concept of matter can be ascribed to a missing law of nature, a law of the relation of forces the discovery of which Kant thought imminent. I conclude that matter theory is central to the Metaphysical Foundations, but that this does not undermine Kant's stated aim of giving the a priori ground of Newtonian science. (shrink)

The goal of this paper is to sketch an account of Kant’s signature metaphysical doctrine (transcendental idealism) that (a) has no supporters – as far as I am aware – in the contemporary literature, and (b) draws its primary motivation (as interpretation) from considerations regarding our practical situation and needs as agents. -/- The consideration I focus on here is that people not only have mental and moral features, but they also appear to us – in our daily experience – (...) to have such features: “[w]e can perceive virtue in our experience (Wir können in der Erfahrung wohl Tugend wahrnehmen)” (24: 906). The same presumably goes for vice: When I see you casually torturing a cat, you appear to me to be brown-haired, wearing jeans, moving your arms, laughing, and so on, but you also appear to me to be vicious and cruel. Your character shines through in your actions. I can then make a defeasible inference from those appearances to the moral reality. -/- Such appearances and inferences play a central role in our practices of praise, blame, forgiveness, and punishment. An interpretation of transcendental idealism that gives primacy to the practical will thus seek to analyze the concepts of experience, acquaintance, and appearance/phenomenon in a capacious-enough way that they can apply to mental and moral features too. If successful, such an interpretation would have a clear practical advantage over those that leave us merely conjecturing from experiences of bodies, gestures, and secondary qualities to moral features that do not appear, or even to the non-appearing features of a distinct set of things.

Thorough comparison of Immanuel Kant’s and Christian Wolff’s divergent appraisals of the science of psychology reveals various ways in which Kant fundamentally altered the Wolffian philosophical apparatus that he inherited. Wolff conceived of a thoroughgoing interplay between empirical and rational psychology, of combining different sorts of cognition in psychology, and of a mathematical science of the soul, or psychometrics. Kant however rejected each of these particular theses and deemed psychology to be no natural science, “properly so-called.” This chapter details these (...) departures from Wolff, explains their basis, and concretizes an underlying contrast in Kant’s and Wolff’s respective philosophical approaches. Namely, whereas Wolff’s philosophical system is malleable, allowing for the combination of various kinds of cognition and methods, in Kant’s Critical philosophy, everything has its proper, preordained niche. At bottom, it is the unyielding rigor of Kant’s system that results in his pessimistic evaluation of the prospects for psychology. (shrink)

The objective of this paper is to provide a critical analysis of the Kantian notion of freedom (especially the problem of the third antinomy and its resolution in the critique of pure reason); its significance in the contemporary debate on free-will and determinism, and the possibility of autonomy of artificial agency in the Kantian paradigm of autonomy. Kant's resolution of the third antinomy by positing the ground in the noumenal self resolves the problem of antinomies; however, invites an explanatory gap (...) between phenomenality and the noumenal self; even if he has successfully established the compatibility of natural causality and non-natural causality through his transcendental argument. This paper is also devoted to establishing the plausibility of the knowledge claim that Kantian reduction of phenomenality has served half of the purpose of the AI scientists on the possibility of Artificial Autonomous Agency.

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.

This essay explores the undervalued methodological elements underpinning Kant’s Transition from Metaphysical Foundations of Natural Science to Physics in Opus postumum. I do this by drawing...

This book focuses on the unity, diversity, and centrality of the notion of law as it is employed in Kant's theoretical and practical philosophy. Eric Watkins argues that, by thinking through a number of issues in various historical, scientific, and philosophical contexts over several decades, Kant is able to develop a univocal concept of law that can nonetheless be applied to a wide range of particular cases, despite the diverse demands that these contexts give rise to. In addition, Watkins shows (...) how Kant comes to view both the generic conception of law which he develops and its different particular instances as crucial components of his systematic philosophy as a whole. This volume's new and unified account of a major current running through Kant's work will be important for scholars interested in numerous aspects of his philosophy, from the theoretical and abstract to the practical and empirical.

In the Metaphysical Foundations of Natural Science, Kant presents an argument for the centrality of <motion> to our concept <matter>. This argument has long been considered either irredeemably obscure or otherwise defective. In this paper I provide an interpretation which defends the argument’s validity and clarifies the sense in which it aims to show that <motion> is fundamental to our conception of matter.

Kant conceives of chemical dissolutions as involving the infinite division and subsequent blending of solvent and solute. In the resulting continuous solution, every subvolume contains a uniform proportion of each reactant. Erich Adickes argues that this account stands in tension with other aspects of Kant’s Critical philosophy and his views on infinity. I argue that although careful analysis of Kant’s conception of dissolution addresses Adickes’ objections, the infinite division inherent to the process is beyond our human cognition, for Kant. Nevertheless, (...) such infinite division may be considered as an idea of reason to make comprehensible chemical reactions, revealing reason to play a pivotal role in the foundations of chemistry. (shrink)

In the Metaphysical Foundations of Natural Science (MFNS) Kant develops a conception of matter that is meant to issue in an alternative to what he takes to be the then reigning empiricist account of density. However, in recent years commentator after commentator has argued that Kant’s attempt on this front is faced with insuperable difficulties. Adickes argues that the MFNS theory of density involves Kant in a vicious circle; Tuschling argues that the circle is part of what led Kant to (...) abandon the theory of matter developed in the MFNS; Förster argues that recognition of this circularity played a significant role in Kant’s development of the project now known as the Opus Postumum; and Westphal argues that the circularity problem serves to demonstrate the “untenability of Kant’s metaphysical method” and therefore helps to explain “the radical revision of the relation between mathematics and metaphysics Kant undertakes in his opus postumum.” Indeed, even Kant seems to think that his theory of density is circular: as noted by all of these commentators, in correspondence with one of his former students Kant declares that this theory “seems to lead however to a circle out of which I am not able to come.” Against this growing tide (and even, it seems, against Kant himself) I defend Kant’s theory of density. I argue that the suspicion of a circle results from a confusion of logical relations with causal conditions, and I argue that even Kant seems to have been taken in by this confusion. (shrink)

It is well known that Kant claims that causal judgments, including judgments about forces, must have an a priori basis. It is less well known that Kant claims that we can perceive the repulsive force of bodies through the sense of touch. Together, these claims present an interpretive puzzle, since they appear to commit Kant to both affirming and denying that we can have perceptions of force. My first aim is to show that both sides of the puzzle have deep (...) roots in Kant's philosophy. My second aim is to present three potential solutions to the puzzle and show that each faces problems. (shrink)

Kant’s preoccupation with architectonics is a characteristic and noteworthy aspect of his thought. Various features of Kant’s argumentation and philosophical system are founded on the precise definitions of the various subdomains of human knowledge and the derivative borders among them. One science conspicuously absent from Kant’s routine discussions of the organization of knowledge is chemistry. Whereas sciences such as physics, psychology, and anthropology are all explicitly located in the architectonic, chemistry finds no such place. In this paper, I examine neglected (...) passages from Kant’s corpus as well as texts regarding chemistry that Kant himself read in order to unveil his views on the definition of chemistry and its relations with the other sciences. These considerations reveal chemistry to be the science that studies the changes of matter into new kinds. Yet Kant idiosyncratically believes that such a change requires an infinite division of matter, effected by chemical forces. Although this understanding of chemical change dovetails with Kant’s dynamical, continualist theory of matter, it implies that chemistry cannot be reduced to physics. Thus, although chemistry stands alongside empirical physics as an applied natural science in Kant’s architectonic, it remains a distinct, independent science. (shrink)

In his Metaphysical Foundations of Natural Science, Kant presents the “pure part” of natural science – that is, the a priori principles holding of matter. This special metaphysics of matter is, Kant claims, grounded on the general metaphysics of nature described in the System of Principles of his first Critique. This chapter develops a comprehensive account of Kant’s framework for natural science that touches on interpretive issues that arise in the transition from general to special metaphysics and that outlines his (...) dynamics and its limitations.

Ott (2009) identifies two kinds of philosophical theories about laws: top-down, and bottom-up. An influential top-down reading, exemplified by Ernst Cassirer, emphasized the ‘mere form of law’. Recent bottom-up accounts emphasize the mind-independent natures of objects as the basis of laws of nature. Stang and Pollok in turn focus on the transcendental idealist elements of Kant’s theory of matter, which leads to the question: is the essence of Kantian matter that it obeys the form of law? I argue that Kant (...) has an independent theory of matter in the Metaphysical Foundations of Natural Science, one that gives what Kant himself calls a ‘real definition’ of matter as a theory-independent (if not mind-independent) entity. I argue that this matter theory underpins physical arguments about inertia and impenetrability, which resemble Einstein’s arguments about the unification of fields in general relativity. (shrink)

This essay explores Kant’s concept of absolute space in the Metaphysical Foundations from the perspective of the development of the relationist interpretation of bodily interactions in the center-of-mass reference frame, a strategy that Huygens had originally pioneered and which Mach also endorsed. In contrast to the interpretations of Kant that stress a non-relationist, Newton-inspired orientation in his critical period work, it will be argued that the content and function of Kant’s utilization of this reference frame strategy places him much closer (...) to Huygens’ relationism than the absolute notions of space and motion favored by Newton and Euler.

Kosmos und Subjektivität – dieses Begriffspaar stellt sogleich einen Antagonismus vor, denn Subjektivität konstituiert sich alleine im irreduziblen Bruch mit der kosmischen Einheit. Gegen Ende des 18. Jahrhunderts kommt es zu diesem Bruch, der sich durch ein Ineinanderwirken von wissenschaftlichen, philosophischen und ästhetischen Diskursen auszeichnet. Als entscheidender Schritt dieser Entwicklung, so die These der Untersuchung, lässt sich die Frühromantik verstehen: Sie insistiert zum einen auf dem Bruch mit der tradierten Vorstellung des Kosmos und entdeckt darin die Möglichkeitsbedingung moderner Subjektivität. Zum (...) anderen hat sie die Erfahrung einer solchen Destruktion noch zur Voraussetzung ihrer eigenen Poetik. (shrink)

In his Metaphysische Anfangsgründe der Naturwissenschaft (MAN), Kant claims that chemistry is an improper, though rational science. The chemistry to which Kant confers this status is the phlogistic chemistry of, for instance, Georg Stahl. In his Opus Postumum (OP), however, Kant espouses a broadly Lavoiserian conception of chemistry. In particular, Kant endorses Antoine Lavoisier's elements, oxygen theory of combustion, and role for the caloric. As Lavoisier's lasting contribution to chemistry, according to some histories of the science, was his emphasis on (...) quantitative methods, Kant's assimilation of the chemical revolution raises the question: did Kant continue to think of chemistry as an improper, though rational, science in OP? In this paper, I answer this question affirmatively. I explain that a proper science requires a priori laws for the mathematical construction of its objects: the mere use of quantitative measurements is insufficient for the satisfaction this requirement. Further, I argue, contra Burkhard Tuschling, that in OP Kant retains a central role for mathematical construction in the foundations of proper natural science. Finally, I contend that the prominent a priori components of chemistry discussed in OP—the aether and the enumeration of the elements—do not make chemistry into a proper science. (shrink)

This paper attempts to shed light on three sets of issues that bear directly on our understanding of Locke and Kant. The first is whether Kant believes Locke merely anticipates his distinction between analytic and synthetic judgments or also believes Locke anticipates his notion of synthetic a priori cognition. The second is what should we as readers of Kant and Locke should think about Kant’s view whatever it turns out to be, and the third is the nature of Kant’s justification (...) for the comparison he draws between his philosophy and Locke’s. I argue (1) that Kant believes Locke anticipates both the analytic-synthetic distinction and Kant’s notion of synthetic a priori cognition, (2) that the best justification for Kant’s claim draws on Locke’s distinction between trifling and instructive knowledge, (3) that the arguments against this claim developed by Carson, Allison, and Newman fail to undermine it, and (4) that Kant’s own justification for his claim is quite different from what many commentators have thought it was (or should have been).

Following the structuring hints given by Plato in his Timaeus you find, that the dialogue – actually Timaeus' lecture – falls in two parts, not in three as Cornford, Brisson and others suggest. The main division follows the two invocations of the gods (27c, 48d). The first part presents the world in its noetic form, poetically described as the work of the demiurg. Timaeus opens this part giving first his premises in the form of an introduction, which lead his presentation. (...) At the end of this part he remarks that the given premises are not enough for his aim, to explain the nature of man. Therefore he adds other guiding principles for the second part in form of a second introduction like in the first part. We need a third principle beside the real beings (the ideas) and the things we perceive. He names it chora and the new form of "`causation"' ananke, necessity. These supplementary principles anable Timaeus to describe the world under our everyday conditions, they mediate the noetic world with the world of our senses. Here is the point we can see a surprising parallel in Kant's work. The Metaphysische Anfangsgründe der Naturwissenschaft correspond to the first part of the Timaeus, because here Kant exposes too the metyphysical foundation of the sciences. Later, in his last years he remarks, that there is a gap between these metaphysical principles and the physics (say of Newton or other). He seeks for a mediating principle and finds it in the "Äther" or "Wärmestoff." Kant was no more able to bring his idea to an end, we only have a lot of variating attempts, named by editors Opus postumum. But the aim of them is clear – and near by the aim that Plato aimed at – to mediate the noetic structure of the world with our everyday world. And this is evidently equivalent with the second introduction in the Timaeus. -/- Here some pages of the book-version: Erwin Sonderegger, Zur Funktion der Chora in Platons Timaios und des Äthers in Kants Übergangsschrift, Königshausen & Neumann, Würzburg 2015.

On an influential view, Newton's mechanics is built into Kant's very theory of exact knowledge. However, Newtonian dynamics had serious explanatory limits already known by 1750. Thus, we might worry that Kant's Analytic is too narrow to ground enough exact knowledge. In this paper, I draw on Enlightenment dynamics to show that Kant's notion of determinate objecthood is sufficiently broad, non-trivial, and still relevant to the present.

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)

Salomon Maimon's Versuch über die Transzendentalphilosophie [Essay in Transcendental Philosophy] (1790) challenges and reworks Kant's arguments in the Kritik der reinen Vernunft [Critique of Pure Reason] (1785, 2nd ed. 1787) about the foundations of natural science and of Newtonian physics in particular. Kant himself was impressed both with Maimon's grasp of his critical project and also with the force of his challenge to it. While Maimon's significance on the later development of German Idealism is now widely acknowledged, another aspect of (...) Maimon's Versuch has not been fully appreciated, namely, its engagement with the central questions of the Spinozastreit [Spinoza Quarrel] that erupted in 1785 with the publication of Friedrich Heinrich Jacobi's Über die Lehre des Spinoza in Briefen an den Herrn Moses Mendelssohn [Concerning the Doctrine of Spinoza in Letters to Moses Mendelssohn]. The Spinoza Quarrel centered on whether and to what extent philosophy's rational understanding of God needs to be grounded in an unmediated and suprarational revelatory experience. This paper is the first extended effort at placing Maimon's Versuch into the context of the Spinoza Quarrel. I argue that the Spinoza Quarrel and Maimon's self-proclaimed philosophical mission in response to it—the replacement of revealed faith by reason—deeply inform the goals he pursues in his Versuch. I show how Maimon's Versuch can be read as not only a response to Kant, but also to Jacobi's defense of the revelatory nature of sense experience in David Hume über den Glauben (1787), the book in which Jacobi offers his own skeptical challenge to Kant's Kritik. Situating Maimon's Versuch as a response to Friedrich Jacobi's David Hume allows us to understand how one of Maimon's objectives in his Versuch is to keep Jacobian Glaube [faith] at bay by demonstrating, using a revised Kantian framework, the conditions of the impossibility of experiencing miracles.

This paper examines the role of Kant's theory of mathematical cognition in his phoronomy, his pure doctrine of motion. I argue that Kant's account of how we can construct the composition of motion rests on the construction of extended intervals of space and time, and the representation of the identity of the part–whole relations the construction of these intervals allow. Furthermore, the construction of instantaneous velocities and their composition also rests on the representation of extended intervals of space and time, (...) reflecting the general approach to instantaneous velocity in the eighteenth century.

Kant's Metaphysical Foundations of Natural Science is one of the most difficult but also most important of Kant's works. Published in 1786 between the first and second editions of the Critique of Pure Reason, the Metaphysical Foundations occupies a central place in the development of Kant's philosophy, but has so far attracted relatively little attention compared with other works of Kant's critical period. Michael Friedman's book develops a new and complete reading of this work and reconstructs Kant's main argument clearly (...) and in great detail, explaining its relationship to both Newton's Principia and eighteenth-century scientific thinkers such as Euler and Lambert. By situating Kant's text relative to his pre-critical writings on metaphysics and natural philosophy and, in particular, to the changes Kant made in the second edition of the Critique, Friedman articulates a radically new perspective on the meaning and development of the critical philosophy as a whole.

Natural Science is a new volume of the Cambridge translations of Kant's works. It makes available some of the most significant texts of Kant's pre-Critical period, some appearing for the first time in English translation. The translations are largely clear and accurate. Eric Watkins is a sure and knowledgeable editor, and provides concise and informative introductions to each text.

We received several critical comments regarding the "The Science of Spiritual Biology." We reply to those criticisms in order to further clarify some of the important points that were made. It is only to be expected that a strong emotional response may be evoked by the revolution in scientific thinking that the modern paradigm of cognitive biology presents. We have to be prepared to accept that, and maintain the integrity of the scientific approach.

This paper examines the origin, range and meaning of the Principle of Action and Reaction in Kant’s mechanics. On the received view, it is a version of Newton’s Third Law. I argue that Kant meant his principle as foundation for a Leibnizian mechanics. To find a ‘Newtonian’ law of action and reaction, we must look to Kant’s ‘dynamics,’ or theory of matter. I begin, in part I, by noting marked differences between Newton’s and Kant’s laws of action and reaction. I (...) argue that these are explainable by Kant’s allegiance to a Leibnizian mechanics. I show (in part II) that Leibniz too had a model of action and reaction, at odds with Newton’s. Then I reconstruct how Jakob Hermann and Christian Wolff received Leibniz’s model. I present (in Part III) Kant’s early law of action and reaction for mechanics. I show that he devised it so as to solve extant problems in the Hermann-Wolff account. I reconstruct Kant’s views on ‘mechanical’ action and reaction in the 1780s, and highlight strong continuities with his earlier, pre-Critical stance. I use these continuities, and Kant’s earlier engagement with post-Leibnizians, to explain the un-Newtonian features of his law of action and reaction. (shrink)

Immanuel Kant's Metaphysical Foundations of Natural Science (1786) provides metaphysical foundations for the application of mathematics to empirically given nature. The application that Kant primarily has in mind is that achieved in Isaac Newton's Principia (1687). Thus, Kant's first chapter, the Phoronomy, concerns the mathematization of speed or velocity, and his fourth chapter, the Phenomenology, concerns the empirical application of the Newtonian notions of true or absolute space, time, and motion. This paper concentrates on Kant's second and third chapters—the Dynamics (...) and the Mechanics, respectively—and argues that they are best read as providing a transcendental explanation of the conditions for the possibility of applying the (mathematical) concept of quantity of matter to experience. Kant again has in mind the empirical measures of this quantity that Newton fashions in the Principia, and he aims to make clear, in particular, how Newton achieves a universal measure for all bodies whatsoever by projecting the static quantity of terrestrial weight into the heavens by means of the theory of universal gravitation. Kant is not attempting to prove a priori what Newton has established empirically but, rather, to clarify the character of Newton's mathematization by building Newton's empirical measures into the very concept of matter that is articulated in the Metaphysical Foundations.

Though Kant is best known for his strictly philosophical works in the 1780s, many of his early publications in particular were devoted to what we would call 'natural science'. Kant's Universal Natural History and Theory of the Heavens (1755) made a significant advance in cosmology, and he was also instrumental in establishing the newly emerging discipline of physical geography, lecturing on it for almost his entire career. In this volume Eric Watkins brings together new English translations of Kant's first publication, (...) Thoughts on the True Estimation of Living Forces (1746-1749), the entirety of Physical Geography (1802), a series of shorter essays, along with many of Kant's most important publications in natural science. The volume is rich in material for the student and the scholar, with extensive linguistic and explanatory notes, editorial introductions and a glossary of key terms. (shrink)

"Living systems are cognitive systems, and living as a process is a process of cognition." -H.R. Maturana, The Biology of Cognition (1970/1980) Just as the cell has gradually come to be understood as a highly regulated and unctionally integrated whole, so too is the biosphere now recognized as a finely balanced ecological whole in which local disturbances can create world-wide climatic catastrophe. The oversimplified ideas of biology that characterized the field in its immature beginning led to the theories of a (...) progressive cumulative development or evolution to explain the present state of Nature. However, today, a more mature understanding of biology has brought with it the realization that Nature can not be the product of a gradual development, based only on the reductionist principles of chemistry and physics. In an ideal situation, where there are no strong interactions with the environment, isolated and purified chemicals may react in a mechanically simple manner, but in a living organism there are no isolated molecules. Everything within the cell interacts with everything else. The constituents of a cell are produced by the cell as much as they produce the cell itself. As the German philosopher Immanuel Kant understood, the unique judgment that allows us to identify a living organism as distinct from non-living matter, is that a living organism is both the cause and effect of itself. Thus, the life of a cell, as much as the life of the biosphere, can only be properly understood as an integrated organic whole. (shrink)
