Kant's Scientific Work

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.

[Michael Friedman] This paper considers the extent to which Kant's vision of a distinctively 'transcendental' task for philosophy is essentially tied to his views on the foundations of the mathematical and physical sciences. Contemporary philosophers with broadly Kantian sympathies have attempted to reinterpret his project so as to isolate a more general philosophical core not so closely tied to the details of now outmoded mathematical-physical theories (Euclidean geometry and Newtonian physics). I consider two such attempts, those of Strawson and McDowell, (...) and argue that they fundamentally distort the original Kantian impulse. I then consider Buchdahl's attempt to preserve the link between Kantian philosophy and the sciences while simultaneously generalizing Kant's doctrines in light of later scientific developments. I argue that Buchdahl's view, while not adequate as in interpretation of Kant in his own eighteenth century context, is nonetheless suggestive of an historicized and relativized revision of Kantianism that can do justice to both Kant's original philosophical impulse and the radical changes in the sciences that have occurred since Kant's day. /// [Graham Bird] Michael Friedman criticises some recent accounts of Kant which 'detach' his transcendental principles from the sciences, and do so in order to evade naturalism. I argue that Friedman's rejection of that 'detachment' is ambiguous. In its strong form, which I claim Kant rejects, the principles of Euclidean geometry and Newtonian physics are represented as transcendental principles. In its weak form, which I believe Kant accepts, it treats those latter principles as higher order conditions of the possibility of both science and ordinary experience. I argue also that the appeal to naturalism is unhelpful because that doctrine is seriously unclear, and because the accounts Friedman criticises are open to objections independent of any appeal to naturalism.

Scientific concepts, laws, theories, models and thought experiments are representations but uniquely different. In On Scientific Representation each is given a full philosophical exploration within an original, coherent philosophical framework that is strongly rooted in the Kantian tradition (Kant, Hertz, Vaihinger, Cassirer). Through a revisionist historical approach, Boniolo shows how the Kantian tradition can help us renew and rethink contemporary issues in epistemology and the philosophy of science.

In this paper I discuss two questions. What does Kant understand by mechanical explanation in the Critique of judgment? And why does he think that mechanical explanation is the only type of the explanation of nature available to us? According to the interpretation proposed, mechanical explanations in the Critique of judgment refer to a particular species of empirical causal laws. Mechanical laws aim to explain nature by reference to the causal interaction between the forces of the parts of matter and (...) the way in which they form into complex material wholes. Just like any other empirical causal law, however, mechanical laws can never be known with full certainty. The conception according to which we can explain all of nature by means of mechanical laws, it turns out, is based on what Kant calls ‘regulative’ or ‘reflective’ considerations about nature. Nothing in Kant’s Critique of judgment suggests that these considerations can ever be justified by reference to how the natural world really is. I suggest that what, upon first consideration, appears to be a thoroughly mechanistic conception of nature in Kant is much more limited than one might have expected. (shrink)

We can observe a connection between some serious environmental problems caused by the overexploitation of environmental resources and the particular conceptions of property rights that are claimed to hold with regard to these resources. In this paper, I investigate whether Kant’s conception of property rights might constitute a basis for justifying property regimes that would overcome some of these environmental problems. Kant’s argument for the right to property, put forward in his Doctrine of right, is complex. In Section 2, I (...) attempt an interpretation. Section 3 works out the defining characteristics of the conception of property rights that Kant’s argument establishes and investigates their implications for determining property regimes in environmental resources. Kant proposes a minimalist notion of the right to property as a triadic relation between persons with regard to an object, justified only on the condition that it is universalizable in the given circumstances. I argue that this notion offers a promising account for determining property relations with regard to environmental resources. By way of illustration, in Section 4, I focus on an example of Kantian property rights in one type of environmental resource: the marine fisheries. (shrink)

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)

Some of Kant's ideas about the mind have had a huge influence on cognitive science, in particular his view that sensory input has to be worked up using concepts or concept-like states and his conception of the mind as a system of cognitive functions. We explore these influences in the first part of the paper. Other ideas of Kant's about the mind have not been assimilated into cognitive science, including important ideas about processes of synthesis, mental unity, and consciousness and (...) self-consciousness. They are the topic of the second part of the paper. (shrink)

In both Introductions to the Critique of Judgment Kant seems to identify the a priori principle at the basis of aesthetic judgments with the principle that guides reflective judgment in its cognitive inquiry of nature, i.e. the purposiveness of nature or systematicity. For instance Kant writes.

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.

Kant famously identified 'What is man?' as the fundamental question that encompasses the whole of philosophy. Yet surprisingly, there has been no concerted effort amongst Kant scholars to examine Kant's actual philosophy of man. This book, which is inspired by, and part of, the recent movement that focuses on the empirical dimension of Kant's works, is the first sustained attempt to extract from his writings on biology, anthropology and history an account of the human sciences, their underlying unity, their presuppositions (...) as well as their methodology. In exploring his philosophical and epistemological foundation of the human sciences, it reveals an unexpected picture of Kant, a picture of a thinker who is profoundly attentive to the diversity, detail and complexity of the human world. (shrink)

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. (shrink)

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)

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.

Since the onset of logical positivism, the general wisdom of the philosophy of science has it that the kantian philosophy of (space and) time has been superseded by the theory of relativity, in the same sense in which the latter has replaced Newton’s theory of absolute space and time. On the wake of Cassirer and Gödel, in this paper I raise doubts on this commonplace by suggesting some conditions that are necessary to defend the ideality of time in the sense (...) of Kant. In the last part of the paper I bring to bear some contemporary physical theories on such conditions. (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)

In this opinion piece, the authors offer their personal and idiosyncratic views of the future of the philosophy of science, focusing on its relationship with the history of science and metaphysics, respectively. With regard to the former, they suggest that the Kantian tradition might be drawn upon both to render the history and philosophy of science more relevant to philosophy as a whole and to overcome the challenges posed by naturalism. When it comes to the latter, they suggest both that (...) metaphysics has much to learn from the philosophy of science and that it offers an array of tools that philosophers of science can themselves appropriate.

Contemporary understandings of nature, or what is ‘natural’, are increasingly subject to debate in our bio-technological age. In this article, I argue that ideas about nature and biology bear a largely unacknowledged relation to normative ideas about sex in western science and philosophy. By examining the concepts of nature and sex in the writings of prominent 18th-century thinkers such as Kant, Rousseau, Burke and Linnaeus, I try to show that in response to the withdrawal, absence or ‘death’ of God that (...) characterizes the Enlightenment worldview, the desire to control sexual expression emerges as a key feature of scientific, aesthetic and philosophical systems of knowledge. Moreover, this desire shapes the concept of nature in such a way that it becomes amenable to the specifically 19th-century figuration of modern biological science. (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 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)

In this article we emphasize the relevance of the Critique of Pure Reason for modern thought and proposes an unorthodox reading of this work that, apart from the ortodox reading that centers itself primarily on the theoretical problems relative to knowledge, priviliges the rol of morality as a det..

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 aim of this work is to analyse the diffrerences between the formal structure of anticipation of perception in classical and in quantum context. I argue that a transcendental point of view can be supported in quantum context if objectivity is defined by an invariant anticipative structure, which has only a predictive character. The classical objectivity, which defined a set of properties having a descriptive meaning must be abandoned in quantum context. I will focus my analysis on Kant's Principle of (...) the Anticipations of Perception. (shrink)

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.

Seit Beginn der frühen Neuzeit ist das naturwissenschaftliche Verfahren maßgeblich durch ein neues Konzept geprägt: das Konzept des experimentellen, gestalterischen Eingriffs in die Natur. Es geht nun nicht mehr darum, eine Geschichte der "freien und ungebundenen Natur" (Bacon) zu erzählen, die in ihrem eigenen Lauf belassen und als vollkommene Bildung betrachtet wird. Es geht vielmehr darum, der "gebundenen und bezwungenen Natur" (Bacon) vermittels der experimentellen Tätigkeit des Menschen die Geheimnisse zu entreißen. Diese technisch-praktische Konzeption grenzt sich explizit von den klassischen (...) kontemplativen Wissenschaftsvorstellungen der Antike ab. Wie es Kant paradigmatisch in Bezug auf Bacon formuliert hat, ist diese "Revolution der Denkart" maßgeblich durch ein gewandeltes Verständnis des Verhältnisses des Menschen zur Natur geprägt. Der Mensch als Experimentator hat für Kant nicht mehr die "Qualität eines Schülers", der sich passiv von der Natur belehren läßt und an ihrem "Leitbande" (Kant) gegängelt wird. Seine neu gewonnene Autorität verleiht ihm vielmehr den Status eines Richters, der nun die Natur nötigen kann, auf gestellte Fragen zu antworten. Die Laborforschung der modernen Naturwissenschaft ist von den Formen der alten Naturwissenschaft so weit entfernt, daß sie den Vorwurf auf sich zog, sie untersuche Artefkakte, aber nicht Natur. Die grundlegenden Theorien über Natur können in der Regel nur unter den künstlichen Bedingungen des Labors aufgestellt werden. Daraus darf aber nicht geschlossen werden, die anhand von Laborphänomenen aufgestellten und getesteten Theorien handelten nicht von der Natur außerhalb der Labore. Aber ihrer exakten und detaillierten Anwendung auf Prozesse außerhalb der Labore stehen eine Fülle von Schwierigkeiten entgegen. Insofern markiert das Labor sehr wohl eine Grenze exakter Naturforschung, die für den Umgang der wissenschaftlich-technischen Zivilisation mit der Natur wichtige Konsequenzen hat. (shrink)

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?

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. (shrink)

Philosophical aesthetics have seen an amazing revival over the past decade, as a radical questioning of the very grounds of Western epistemology has revealed that descriptions of what used to be seen as specific to aesthetic experience can instead be viewed as a general model for human cognition. In this revival, no text in the classical corpus of Western philosophy has been more frequently discussed and debated than the dense, complex paragraphs inserted into Kant's Critique of Judgment as sections 23-29: (...) the Analytic of the Sublime. This book is a rigorous explication de texte, a close reading of these sections. The Analytic of the Sublime, he points out, tries to argue that human thought is always constituted through a similar incompatibility between different intellectual and affective faculties. These lessons thus try to isolate the analysis of a differend of feeling in Kant's text, which is also the analysis of a feeling of differend, and to connect this feeling with the transport that leads all thought (critical thought included) to its limits.

¿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)
