Kant's Scientific Work

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 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.

Kant’s philosophy of science takes on sharp contour in terms of his interaction with the practicing life scientists of his day, particularly Johann Blumenbach and the latter’s student, Christoph Girtanner, who in 1796 attempted to synthesize the ideas of Kant and Blumenbach. Indeed, Kant’s engagement with the life sciences played a far more substantial role in his transcendental philosophy than has been recognized hitherto. The theory of epigenesis, especially in light of Kant’s famous analogy in the first Critique, posed crucial (...) questions regarding the ‘looseness of fit’ between the constitutive and the regulative in Kant’s theory of empirical law. A detailed examination of Kant’s struggle with epigenesis between 1784 and 1790 demonstrates his grave reservations about its hylozoist implications, leading to his even stronger insistence on the discrimination of constitutive from regulative uses of reason. The continuing relevance of these issues for Kant’s philosophy of science is clear from the work of Buchdahl and its contemporary reception. (shrink)

Anthropology was a new field of study when Kant first began lecturing on it in 1772, and Kant himself was the first academic to teach regular courses in this area. As is well known, his own approach to anthropology is self-described as ‘pragmatic’, and Kant’s pragmatic anthropology differs markedly from the anthropologies that other early contributors to the new discipline were advocating. In this essay I focus on a fundamental feature of Kant’s anthropology that has been under-appreciated in previous discussions; (...) namely, the particular conception of human nature that he believes anthropology, when pursued properly, leads to. I call this conception a cosmopolitan conception of human nature. In addition to establishing the central importance of this idea for Kant’s project in anthropology, I also try in this essay to unravel some of its ambiguities and tensions as well as to highlight its underlying moral motives. The cosmopolitan conception of human nature that is central to Kant’s anthropology is a further indication of the significance of his anthropology for ethics.Keywords: Immanuel; Kant; Anthropology; Pragmatic; Cosmopolitan; Human nature.

The essay, ‘A renewed attempt to answer the question: “Is the human race continually improving?”’ appeared as Part II of Kant’s 1798 publication, The conflict of the faculties, where it was subordinated under a second title: ‘The conflict of the philosophy faculty with the faculty of law’. How did this new situation affects the meaning of the essay? My argument considers first, the conflict of the faculty of philosophy with the faculty of law; second, the earlier philosophy of history Kant (...) had developed; and, finally, the revision of this position in ‘A renewed attempt’. The situation of his argument in the contest between the philosophical and the legal faculties points to other veins of argumentation in Kant’s political theory, particularly his appeal to a principle of publicity, but they hardly achieve the theoretical clarity or the systematic centrality they should command. They are displaced in the quest for prediction of the future history of mankind. The question of human progress exceeds the frame of the coordination of the university, and the main question must remain: what was new in Kant’s approach to the question of human progress, and was it in fact an enhancement of his philosophy of history? In those terms, ‘A renewed attempt’ must be regarded a distinct failure. Its innovations prove problematic. Its retreats and equivocations, moreover, threaten to undermine the grander vision of Kant’s philosophical history and his political theory, entangling them in an unacceptably theological recourse.Keywords: Immanuel Kant; Philosophy of history; Progress; Publicity; Providence.

This paper examines Kant’s anthropological project and its relationship to his conception of ‘man’ in order to show that Kant’s answer to the question ‘what is man?’ entails a decisive re-evaluation of traditional conceptions of human nature. I argue that Kant redirects the question ‘what is man?’ away from defining man in terms of what he is, and towards defining him in terms of what he does, in particular through the distinction between three levels of what I will call ‘man’s (...) praxis’: the levels of technicality, prudence, and morality. As soon as man is understood in terms of what he makes of himself rather than in terms of what he is, two crucial issues arise: what is the purpose of his making? And how can he reach this destination? My claim is that whilst the first question is answered by ethics and a doctrine of prudence, the second question is answered by anthropology. In this sense, anthropology plays the crucial role of identifying the worldly helps and hindrances to the realisation of man’s purposes—and this is the reason why it should be understood as a ‘pragmatic’ discipline.Keywords: Immanuel; Kant; Pragmatic; Anthropology; Praxis; Aliens; Human nature.

One of the perennially intriguing questions regarding Kant’s approach to the human sciences is the relation between his ‘transcendental psychology’ and empirical cognitive psychology. In this paper I compare his analysis of the a priori conditions of human cognition in the Critique of pure reason with his empirical account of the human cognitive faculties in his Anthropology from a pragmatic point of view. In comparing his approach to self-consciousness, sensibility, imagination, and understanding in these two works, I argue that Kant (...) distinguishes between the transcendental and empirical aspects of the human cognitive faculties, and regards the transcendental functions as configuring the empirical faculties of human consciousness, or as giving them the structure that they require to become faculties of cognition. I then show that the cognitive faculties of human beings may vary in their empirical operation, even while they are configured by the same transcendental structure. Finally, I characterize Kant’s transcendental psychology in the first Critique as an account of the faculties that are required for a mind to be an agent or subject of cognition, corresponding to his account of the conditions that are required universally and necessarily for something to be an object of cognition.Keywords: Immanuel Kant; Anthropology; Psychology; Cognition; Transcendental; Empirical.

It is argued that geometrical intuition, as conceived in Kant, is still crucial to the epistemological foundations of mathematics. For this purpose, I have chosen to target one of the most sympathetic interpreters of Kant's philosophy of mathematics – Michael Friedman – because he has formulated the possible historical limitations of Kant's views most sharply. I claim that there are important insights in Kant's theory that have survived the developments of modern mathematics, and thus, that they are not so intrinsically (...) bound up with the logic and mathematics of Kant's time as Friedman will have it. These insights include the idea that mathematical knowledge relies on the manipulation of objects given in quasi-perceptual intuition, as Charles Parsons has argued, and that pure intuition is a source of knowledge of space itself that cannot be replaced by mere propositional knowledge. In particular, it is pointed out that it is the isomorphism between Kantian intuition and a spatial manifold that underlies both the epistemic intimacy of the most fundamental type of geometrical intuition as well as that of perceptual acquaintance.

The aim of this paper is to show that for Kant, a combination of epigenesis and monogenesis is the condition of possibility of anthropology as he conceives of it and that moreover, this has crucial implications for the biological dimension of his account of human nature. More precisely, I begin by arguing that Kant’s conception of mankind as a natural species is based on two premises: firstly the biological unity of the human species (monogenesis of the human races); and secondly (...) the existence of ‘seeds’ which may or may not develop depending on the environment (epigenesis of human natural predispositions). I then turn to Kant’s account of man’s natural predispositions and show that far from being limited to the issue of races, it encompasses unexpected human features such as gender, temperaments and nations. These predispositions, I argue, are means to the realisation of Nature’s overall purpose for the human species. This allows me to conclude that man’s biological determinism leads to the species’ preservation, cultivation and civilisation. (shrink)

This _Companion_ provides an authoritative survey of the whole range of Kant’s work, giving readers an idea of its immense scope, its extraordinary achievement, and its continuing ability to generate philosophical interest. Written by an international cast of scholars Covers all the major works of the critical philosophy, as well as the pre-critical works Subjects covered range from mathematics and philosophy of science, through epistemology and metaphysics, to moral and political philosophy.

This thesis attempts to argue against an influential interpretation of Kant's philosophy of mathematics according to which the role of pure intuition is primarily logical. Kant's appeal to pure intuition, and consequently his belief in the synthetic character of mathematics, is, on this view, a result of the limitations of the logical resources available in his time. In contrast to this, a reading is presented of the development of Kant's philosophy of mathematics which emphasises a much richer philosophical role for (...) intuition, beyond that of filling in deductive gaps in mathematical arguments. This role is largely determined by two factors: on the one hand, the epistemological gap in a traditional account of mathematical certainty, and on the other hand, the metaphysical worry raised by the followers of Leibniz and Wolff regarding the status of mathematics as a science consisting of truths. ;By appreciating how Kant's philosophy of mathematics developed against the background of what he saw as a conflict between the 'metaphysicians' and the 'mathematicians', we can see how the doctrine of pure intuition was required to fill the gaps in the account of the method and certainty of mathematics which Kant presents in the Prize Essay of 1764. This conflict takes its sharpest form between the monadists who uphold the metaphysical necessity of simple elements, and the geometers who uphold the infinite divisibility of space. In the Prize Essay Kant indirectly addresses this conflict by comparing the two disciplines. He asserts that the method of attaining certainty in mathematics is different from the method of metaphysics, and that as a result of this difference--primarily the different roles of definitions in each--mathematics is capable of a higher degree of certainty than metaphysics. He does not, however, explain this difference. Such an explanation seems particularly important in light of Kant's wish to secure geometry against the challenge of metaphysics. This thesis attempts to show that it is to provide such an explanation, to provide a philosophical grounding for the Prize Essay account, that Kant invokes the doctrine of pure intuition in his later account of mathematical knowledge.

The question of the dimensionality of space has informed the development of physics since the beginning of the twentieth century in the quest for a unified picture of quantum processes and gravitation. Scientists have worked within various approaches to explain why the universe appears to have a certain number of spatial dimensions. The question of why space has three dimensions has a genuinely philosophical nature that can be shaped as a problem of justifying a contingent necessity of the world. In (...) contrast to explanations of three-dimensionality based on anthropic arguments, we support the search for a theory that provides a justification for the dimensionality of space based on a combination of deductive and inductive reasoning applied to science. In doing so, we argue that Kant correctly approached the question in “Thoughts on the true estimation of living forces” by connecting space dimensionality and the inverse square law. In expounding the strategy of Kant’s argument, we describe the main features of a general Kantian explanation of the dimensionality of space and discuss them with respect to current accounts of explanation in the philosophy of science, such as inference to the best explanation and the deductive-nomological model.

In this book, David Stump traces alternative conceptions of the a priori in the philosophy of science and defends a unique position in the current debates over conceptual change and the constitutive elements in science. Stump emphasizes the unique epistemological status of the constitutive elements of scientific theories, constitutive elements being the necessary preconditions that must be assumed in order to conduct a particular scientific inquiry. These constitutive elements, such as logic, mathematics, and even some fundamental laws of nature, were (...) once taken to be a priori knowledge but can change, thus leading to a dynamic or relative a priori. Stump critically examines developments in thinking about constitutive elements in science as a priori knowledge, from Kant’s fixed and absolute a priori to Quine’s holistic empiricism. By examining the relationship between conceptual change and the epistemological status of constitutive elements in science, Stump puts forward an argument that scientific revolutions can be explained and relativism can be avoided without resorting to universals or absolutes.

Marburg Neo-Kantianism has attracted substantial interest among contemporary philosophers drawn by its founding idea that the success of advanced theoretical science is a given fact and it is the task of philosophical inquiry to ground the objectivity of scientific achievement in its a priori sources (Cohen and Natorp 1906, p. i). The Marburg thinkers realized that recent advances and developments in the mathematical sciences had changed the character of Kant’s transcendental project, demanding new methods and approaches to establish the objectivity (...) of the latest insights into physical reality. Hermann Cohen, one of the founders of the Marburg School, attempted to base the objectivity of science on the concepts of .. (shrink)

In Chapter I, I discuss Buchdahl’s view that the possibility of empirical lawlikeness could not have been established in the Principles of the Critique given the differences between transcendental, metaphysical and empirical lawlikeness, and the connection between the faculty of Reason and empirical lawlikeness. I then discuss the general conditions for empirical hypotheses according to Kant, which include the justification of the method by which an empirical hypothesis is obtained and the establishment of the general and specific constructability of the (...) empirical concept. -/- *In Chapter II, I discuss the nature of the general construction of concepts which is treated in the Schematism of the Critique, surveying the views of Pippin, Allison, Bennett and Butts in an effort both to make sense of a difficult part of the Critique and to demonstrate that the Schematism is indeed where Kant demonstrates how the construction of empirical concepts in general is possible. -/- *In Chapter III, I discuss Brittan’s and Butts’ views on the nature of the specific construction of empirical concepts, defending Butts’ interpretation as compatible with Buchdahl’s view that gaps exist between kinds of lawlikeness for Kant and, because of its connection with an interpretation of how metaphysical lawlikeness figures in the Metaphysical Foundations of Natural Science, insofar as it helps us to establish the possibility of empirical lawlikeness and natural science.

Through nineteenth-century intermediaries, the model of the mind developed by Immanuel Kant has had an enormous influence on contemporary cognitive research. Indeed, Kant could be viewed as the intellectual godfather of cognitive science. In general structure, Kant's model of the mind shaped nineteenth-century empirical psychology and, after a hiatus during which behaviourism reigned supreme , became influential again toward the end of the twentieth century, especially in cognitive science. Kantian elements are central to the models of the mind of thinkers (...) otherwise as different as Sigmund Freud and Jerry Fodor, for example. (shrink)

Kant’s teleology as presented in the Critique of Judgment is commonly interpreted in relation to the late eighteenth-century biological research of Johann Friedrich Blumenbach. In the present paper, I show that this interpretative perspective is incomplete. Understanding Kant’s views on teleology and biology requires a consideration of the teleological and biological views of Christian Wolff and his rationalist successors. By reconstructing the Wolffian roots of Kant’s teleology, I identify several little known sources of Kant’s views on biology. I argue that (...) one of Kant’s main contributions to eighteenth-century debates on biology consisted in demarcating biology from metaphysics. Kant rejected Wolffian views on the hierarchy of sciences, according to which propositions specifying the functions of organisms are derived from theological truths. In addition, Kant argued that organic self-organization necessitates a teleological description in order to show that self-organization does not support materialism. By demarcating biology and metaphysics, Kant made a small yet important contribution to establishing biology as a science. (shrink)

¿Cómo hay que entender la tesis de Hegel en la Lógica de que "la teleología es la verdad del mecanismo"? La afirmó contra Kant, desde luego; a saber, contra la posibilidad de que lo que parece teleológico sea sólo mecánico; pero no en el sentido de un compromiso dogmático con la realidad de fines naturales y tampoco en el de una refutación del mecanicismo como la que Fichte busca con su radicalización de la filosofía trascendental. Aquí se examina qué posibilidades (...) quedan abiertas cuando se cierran aquéllas. How should one understand the claim that "Teleology is the truth of Mechanism" advanced by Hegel in the Logic? It certainly opposes Kant's position in denying the possibility that what seems to be teleological is only mechanical, but not in the sense of a dogmatic commitment to the reality of natural ends or in the sense of a refutation of mechanicism as in Fichte's radicalization of transcendental philosophy. I examine in this paper which alternatives remain open once these are discarded. (shrink)

The article investigates the way in which Peter Mittelstaedt has been contributing to the philosophy of physics for half a century. It is shown that he pursues a path between rationalism and empiricism in the sense of Erhard Scheibe’s philosophy of the physicists. Starting from Kant’s a priori he gives a rational reconstruction of the conceptual revolutions of 20th century physics. The central topic of his philosophy of physics is the quest for semantic self-consistency, which for quantum mechanics is a (...) hard nut to crack. (shrink)

The so-called .Karlsschulrede. (1793) of the German naturalist Carl Friedrich Kielmeyer can be considered as a keystone to the understanding of"Naturphilosophie" both in German idealism (Schelling) and the romantic period.Kielmeyer's work considers life as the result of specific forces in the organic realm and thereby searches to explain the harmony of organic existence anddevelopment. Taking into account Kant.s outlines for a lifescience in the "Kritik der Urteilskraft" (1790), Kielmeyer's notion of teleological processes in nature is sketched. The historical and epistemological (...) relevance of this "vital-materialistic" (Lenoir) theory of life can be characterized by three major transformations in the understanding of nature in the "Karlsschulrede": First, the development of a holistic, organological view on the world, second, the emphasis on phenomena of life as historical processes and third the analogy between organism and mind. These issues found the strong influence of Kielmeyer's text on philosophy and science in the early 19th-century. (shrink)

I once wrote to Daya ji about what seemed to me a paradox in contemporary Indian philosophy. It is one thing that Indian philosophers in academia do not engage with science, or even with its history and philosophy. It is quite another thing that they do not engage with ethics. Ethics, after all, is at the core of philosophy. Without an ethical principle one often does not know how to respond to something fundamentally new, such as the bewildering variety of (...) new developments in science and technology that impinge on our daily life. I was disappointed that Indian philosophers remain engaged in the study of Spinoza, Kant, Hegel, and the like, or are immersed in Sanskrit texts—neither of which provide much guidance .. (shrink)

The article attempts to reconsider the relationship between Leibniz’s and Kant’s philosophy of geometry on the one hand and the nineteenth century debate on the foundation of geometry on the other. The author argues that the examples used by Leibniz and Kant to explain the peculiarity of the geometrical way of thinking are actually special cases of what the Jewish-German mathematician Felix Hausdorff called “transformation principle”, the very same principle that thinkers such as Helmholtz or Poincaré applied in a more (...) general form in their celebrated philosophical writings about geometry. The first two parts of the article try to show that Leibniz’s and Kant’s philosophies of geometry, despite their differences, appear to be preoccupied with the common problem of the impossibility to grasp conceptually the intuitive difference between two figures (such as a figure and its scaled, displaced or mirrored copy). In the third part, it is argued that from the perspective of Hausdorff’s philosophical-geometrical reflections, this very same problem seems to find a more radical application in Helmholtz’s or Poincaré’s thought experiments on the impossibility of distinguishing distorted copies of our universe from the original one. I draw the conclusion that in Hausdorff’s philosophical work, which has received scholarly attention only recently, one can find not only an original attempt to frame these classical arguments from a set-theoretical point of view, but also the possibility of considering the history of philosophy of geometry from an uncommon perspective, where especially the significance of Kant’s infamous appeal to “intuition” can be judged by more appropriate standards.

The belief that laws of nature are contingent played an important role in the emergence of the empirical method of modern physics. During the scientific revolution, this belief was based on the idea of voluntary creation. Taking up Peter Mittelstaedt’s work on laws of nature, this article explores several alternative answers which do not overtly make use of metaphysics: some laws are laws of mathematics; macroscopic laws can emerge from the interplay of numerous subsystems without any specific microscopic nomic structures (...) (John Wheeler’s “law without law”); laws are the preconditions of scientific experience (Kant); laws are theoretical abstractions which only apply in very limited circumstances (Nancy Cartwright). Whereas Cartwright’s approach is in tension with modern scientific methodology, the first three strategies count as illuminating, though partial answers. It is important for the empirical method of modern physics that these three strategies, even when taken together, do not provide a complete explanation of the order of nature. Thus the question of why laws are valid is still relevant. In the concluding section, I argue that the traditional answer, based on voluntary creation, provides the right balance of contingency and coherence which is in harmony with modern scientific method.

The Scottish historian William Robertson's works on European encounter with non-European civilizations (History of America, 1777; Historical Disquisition [?] of India, 1791) received a great deal of attention in contemporary Germany. Through correspondence with Robertson, as well as by reviewing and translating his texts, Johann Reinhold Forster and his son Georg took an active part in this process. The younger Forster also became simultaneously involved in a debate which was unfolding on the German intellectual scene concerning the different or equal (...) ?value? (Wert) of the various ?races of mankind? (Menschenrassen), engaging especially the relevant views advanced by the Göttingen historian Christoph Meiners and Immanuel Kant. The debate was firmly embedded in the context of an emerging ?science of man? in the German Enlightenment, to which Forster contributed an almost incomparable richness of empirical knowledge as well as theoretical sophistication. Forster's direct engagement with Robertson's work during the same period (mid-1780s to the early 1790s) creates a context through which the Wissenschaft vom Menschen in the Aufklärung and the Scottish version of the science of man ? built on the neighbour disciplines to which Robertson's historiography was crucially indebted ? is set in an interesting comparative light. This paper, part of a comprehensive project tracing the German reception of Robertson as an instance of inter-cultural exchange in the Enlightenment, will exploit the opportunities presented by one particular and documented case for a general comparison of enlightened ?sciences of man?

This paper argues that mathematical chemistry (MC) cannot just imitate mathematical physics (MP) but needs to develop its own interdisciplinary approach to avoid predictable obstacles. Although Kant's dictum that chemistry does not lend itself to mathematical treatment was already refuted during his own lifetime, any useful combination of mathematics and chemistry essentially differs from MP. While the latter has a longstanding disciplinary tradition of its own, MC requires true interdisciplinary work and needs to bridge two fundamentally different methodological traditions. I (...) suggest that MC follows methodological pluralism and develops new mathematical theories of chemistry that avoid telling causal stories. However, this makes MC susceptible to various epistemological pitfalls to be explained with examples from the earlier history of mathematical chemistry. I argue that all these pitfalls can be avoided through the collaboration with experimental chemists and finally point to geometrical symmetry theory as a model of a non-causal mathematical approach in science that emerged out of interdisciplinary efforts in 19th-century mineralogy.
