Kant: Metaphysical Foundations of Natural Science

The first genuine and comprehensive English-language handbook to the study of Kant's philosophy, containing sections on Kant's key works, the philosophical and historical contexts of his philosophy, essays on the reception and influence of the Kantian philosophy, a lexical A-Z list of lemmata addressing central themes and concepts of Kant's thought and an extensive English-language bibliography of secondary literature.

The principles of Kant's pure physics (conservation of quantity of matter, inertia, equality of action and reaction) are a priori in the same sense as are the principles of the understanding. We account for the empirical content of physics by showing that the pure principles operate as rules for generating wellformed empirical descriptions, and as rules for analysis of motion. The relationship between the metaphysics of matter and empirical descriptions is neither deductive, nor as loose as Buchdahl alleges. Belief that (...) a priori principles will apply to empirical cases requires acceptance of methodological presuppositions, chief among which is the principle of affinity. (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).

In contrast to the previously widespread view that Kant's work was largely in dialogue with the physical sciences, recent scholarship has highlighted Kant's interest in and contributions to the life sciences. Scholars are now investigating the extent to which Kant appealed to and incorporated insights from the life sciences and considering the ways he may have contributed to a new conception of living beings. The scholarship remains, however, divided in its interest: historians of science are concerned with the content of (...) Kant's claims, and the ways in which they may or may not have contributed to the emerging science of life, while historians of philosophy focus on the systematic justifications for Kant's claims, e.g., the methodological and theoretical underpinnings of Kant's statement that living beings are mechanically inexplicable. My aim in this paper is to bring together these two strands of scholarship into dialogue by showing how Kant's methodological concerns (specifically, his notion of reflective judgment) contributed to his conception of living beings and to the ontological concern with life as a distinctive object of study. I argue that although Kant's explicit statement was that biology could not be a science, his implicit and more fundamental claim was that the study of living beings necessitates a distinctive mode of thought, a mode that is essentially analogical. I consider the implications of this view, and argue that it is by developing a new methodology for grasping organized beings that Kant makes his most important contribution to the new science of life.

Abstract: This article contends that the relation of early logical empiricism to Kant was more complex than is often assumed. It argues that Reichenbach's early work on Kant and Einstein, entitled The Theory of Relativity and A Priori Knowledge (1920) aimed to transform rather than to oppose Kant's Critique of Pure Reason. One the one hand, I argue that Reichenbach's conception of coordinating principles, derived from Kant's conception of synthetic a priori principles, offers a valuable way of accounting for the (...) historicity of scientific paradigms. On the other hand, I show that even Reichenbach, in line with Neo-Kantianism, associated Kant's view of synthetic a priori principles too closely with Newtonian physics and, consequently, overestimated the difference between Kant's philosophy and his own. This is even more so, I point out, in the retrospective account logical empiricism presented of its own history. Whereas contemporary reconstructions of this history, including Michael Friedman's, tend to endorse this account, I offer an interpretation of Kant's conception of a priori principles that contrasts with the one put forward by both Neo-Kantianism and logical empiricism. On this basis, I re-examine the early Reichenbach's effort to accommodate these principles to the paradigm forged by Einstein. (shrink)

In this essay, I call attention to Kant’s and Whewell’s attempt to provide bridging principles between a priori principles and scientific laws. Part of Kant’s aim in the Opus postumum (ca. 1796-1803) was precisely to bridge the gap between the metaphysical foundations of natural science (on the Metaphysical Foundations of Natural Science (1786) see section 1) and physics by establishing intermediary concepts or ‘Mittelbegriffe’ (henceforth this problem is referred to as ‘the bridging-problem’). I argue that the late-Kant attempted to show (...) that the concept of ‘moving force’, an intermediary concept derived from a priori principles, could be given empirical content so that concrete scientific knowledge is arrived at. Thus, the late-Kant wished not only to show that proper scientific laws are necessary a priori (as he had shown in the Metaphysical Foundations of Natural Science) but also that intermediary concepts could be derived from a priori principles which, when interpreted empirically, resulted in the specific forces as established by physics (see section 2). Of course, William Whewell never knew about Kant’s Opus postumum and his attempt to bridge the gap between the metaphysical foundations of science and physics. However, it is striking that Whewell had similar concerns about the Critique of Pure Reason and the Metaphysical Foundations of Natural Science as Kant himself. According to Whewell, the Kantian project was incomplete because it did not show how ‘modifications’ (in the sense of concretizations) of a priori principles could result in empirical laws (section 3). Next, it will be argued, by taking into account several of Whewell’s philosophical notebooks which have scarcely been studied systematically, that Whewell’s doctrine of Fundamental Ideas grew out of his dissatisfaction with the Kantian project with respect to the bridging problem and that his own philosophical position should be seen as an attempt to bypass the bridging-problem.

In Kant's Metaphysical Foundations of Natural Science are found a dynamist reduction of matter and an account of the communication of motion by impact. One would expect to find an analysis of the causal mechanism involved in the communication of motion between bodies given in terms of the fundamental dynamical nature of bodies. However, Kant's analysis, as given in the discussion of his third law of mechanics (an action-reaction law) is purely kinematical, invoking no causal mechanisms at all, let alone (...) dynamist mechanisms, in the explanation. It is argued that the reason for the non-incorporation of Kant's theory of matter in the account of impact is his overriding desire to provide a mathematical framework to explain the communication of motion, a provision which Kant felt to be impossible in the context of a metaphysical dynamism.

Kant's transcendental idealism is often praised for resolving antinomies and attacked for representationalism. Such an attitude prevailed even among Kant's contemporaries. As early as 1787 Friedrich Heinrich Jacobi noted that the "main advantage" of the doctrine that we cognize only appearances and not things in themselves is that it resolves the antinomical conflicts in which previous metaphysics was embroiled and thus "sets reason at rest." Yet, at the same time, Jacobi bemoaned that the transcendental idealist cannot consistently uphold the positive (...) consequences of his "transcendental ignorance" without likewise accepting the negative consequence that his doctrine is tantamount to "speculative egoism,"1 insofar ..

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.

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.

his paper explores the relationship between Kant’s views on the metaphysical foundations of Newtonian mathematical physics and his more general transcendental philosophy articulated in the Critique of pure reason. I argue that the relationship between the two positions is very close indeed and, in particular, that taking this relationship seriously can shed new light on the structure of the transcendental deduction of the categories as expounded in the second edition of the Critique.Author Keywords: Kant; Mathematical physics; Transcendental deduction.

Kant's understanding of two significant philosophical issues, the status of space and the nature of scientific explanation, can be illuminated by considering his reaction to the emergence of Newtonian gravitational physics. Although Kant accepts---with important provisos---the view that space bears an absolute status, he rejects Newton's philosophical interpretation of that status. Characterizing this rejection poses a problem. It is commonly thought that Kant's conception of space can be understood as a competitor to Newtonian absolutism and Leibnizian relationalism per se, but (...) Kant contends that these views commit a common mistake. Leibniz and Newton each picture space as real in a philosophically significant sense; Kant seeks to reject the reality of space in the Critique of Pure Reason. I argue that, from Kant's perspective, contending that space is absolute is compatible with thinking that it lacks reality. This illuminates, in turn, Kant's conception of things-in-themselves. ;In his work on scientific explanation, Wesley Salmon distinguishes an "ontic" conception, according to which explanations make reference to the cause of events or of phenomena; and an "epistemic" conception, according to which explanations make reference to covering laws. To begin with, I argue that Newtonian physics, which famously fails to discover gravity's cause, can be interpreted as providing nomological explanations of gravitational phenomena like the planetary orbits. Unlike Leibniz, who explicitly rejects the law of universal gravitation's explanatory status, Kant recognizes the significance of this notion for understanding the science of Newton's Principia Mathematica. In tandem, several puzzling aspects of the conception of spatial objects presented in the Critique of Pure Reason can be illuminated by considering Kant's adoption of a related Newtonian view: the content of the ascription of a force to a spatial object, or to a system of such objects, is exhausted by the physical law governing the operation of that force. In this respect, in rejecting a Leibnizian conception of force, Kant adopts an explicitly Newtonian conception; Kant's conception of spatial objects is closely linked with that adoption. Thus, important aspects of Kant's metaphysics can be illuminated by considering their relation to philosophical issues raised by Newtonian physics. (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)

The purpose of the Cambridge edition is to offer translations of the best modern German edition of Kant's work in a uniform format suitable for Kant scholars. This volume is the first to assemble in historical sequence the writings that Kant published between 1783 and 1796 to popularize, summarize, amplify and defend the doctrines of his masterpiece, the Critique of Pure Reason of 1781. The best known of them, the Prolegomena, is often recommended to beginning students, but the other texts (...) are also vintage Kant and are important sources for a fully-rounded picture of Kant's intellectual development. As with other volumes in the series there are copious linguistic notes and a glossary of key terms. The editorial introductions and explanatory notes shed light on the critical reception accorded Kant by the metaphysicians of his day and on Kant's own efforts to derail his opponents. (shrink)

This volume is the first ever English translation of Kant's last major work, the so-called Opus Postumum, a work Kant himself described as his 'chef d'oeuvre' and as the keystone of his entire philosophical system. It occupied him for more than the last decade of his life. Begun with the intention of providing a 'transition from the metaphysical foundations of natural science to physics,' Kant's reflections take him far beyond the problem he initially set out to solve. In fact, he (...) reassesses a whole series of fundamental topics of transcendental philosophy: the thing in itself, the nature of space and time, the concept of the self and its agency, the idea of God, and the unity of theoretical and practical reason. Though never completed, the text reaches a logical albeit not fully developed, conclusion. (shrink)

Kant was centrally concerned with issues in the philosophy of natural science throughout his career. The Metaphysical Foundations of Natural Science presents his most mature reflections on these themes in the context of both his 'critical' philosophy, presented in the Critique of Pure Reason, and the natural science of his time. This volume presents a new translation, by Michael Friedman, which is especially clear and accurate. There are explanatory notes indicating some of the main connections between the argument of the (...) Metaphysical Foundations and the first Critique - as well as parallel connections to Newton's Principia. The volume is completed by an historical and philosophical introduction and a guide to further reading. (shrink)
