Kant: Philosophy of 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)

I argue that Immanuel Kant's critical philosophy—in particular the doctrine of transcendental idealism which grounds it—is best understood as an `epistemic' or `metaphilosophical' doctrine. As such it aims to show how one may engage in the natural sciences and in metaphysics under the restriction that certain conditions are imposed on our cognition of objects. Underlying Kant's doctrine, however, is an ontological posit, of a sort, regarding the fundamental nature of our cognition. This posit, sometimes called the `discursivity thesis', while considered (...) to be completely obvious and uncontroversial by some, has nevertheless been denied by thinkers both before and after Kant. One such thinker is Jakob Friedrich Fries, an early neo-Kantian thinker who, despite his rejection of discursivity, also advocated for a metaphilosophical understanding of critical philosophy. As I will explain, a consequence for Fries of the denial of discursivity is a radical reconceptualisation of the method of critical philosophy; whereas this method is a priori for Kant, for Fries it is in general empirical. I discuss these issues in the context of quantum theory, and I focus in particular on the views of the physicist Niels Bohr and the Neo-Friesian philosopher Grete Hermann. I argue that Bohr's understanding of quantum mechanics can be seen as a natural extension of an orthodox Kantian viewpoint in the face of the challenges posed by quantum theory, and I compare this with the extension of Friesian philosophy that is represented by Hermann's view. -/- A shorter version of this paper, focusing specifically on the views of Grete Hermann, has been published as: Cuffaro, Michael (2023).

Kant's special metaphysics is intended to provide the a priori foundation for Newtonian science, which is to be achieved by exhibiting the a priori content of Newtonian concepts and laws. Kant envisions a two-step mathematical construction of the dynamical concept of matter involving a geometrical construction of matter’s bulk and a symbolic construction of matter’s density. Since Newton himself defines quantity of matter in terms of bulk and density, there is no reason why we shouldn’t interpret Kant’s Dynamics as a (...) defence of a Newtonian concept of matter. When Kant’s reasoning is understood in relation to his criteria for mathematical construction, it is possible to maintain that matter theory is central to the Metaphysical Foundations, but that this does not undermine Kant’s stated aim of giving an a priori foundation for Newtonian science.

Kant scholars have paid relatively little attention to his raciology. They assume that his racism, as personal prejudice, can be disentangled from his core philosophy. They also assume that racism contradicts his moral theory. Lu-Adler challenges both assumptions. She shows how Kant’s raciology—divided into racialism and racism—is integral to his philosophical system as a whole. She also rejects the individualistic approach to Kant and racism. Instead, she uses the notion of racism as ideological formation to demonstrate how Kant, from his (...) social location both as a prominent scholar and as a lifelong educator, participated in the formation of modern racist ideology. -/- As a scholar, Kant developed a groundbreaking scientific theory of race from the standpoint of a philosophical investigator of nature or Naturforscher. As an educator, he transmitted denigrating depictions of the racialized others and imbued them with normative relevance. In both roles, he presented a worldview that excluded nonwhites from such goods as recognitional respect and candidacy for cultural and moral achievements. Some effects of this worldview are still palpable today. Scholars who research and teach Kant’s philosophy therefore have an unshakable burden to take part in the ongoing antiracist struggles, through their teaching practices as well as their scholarship. And they must do so in a color-conscious as opposed to colorblind way, with a pragmatic attention to nonideal social realities and a clear normative orientation toward substantial racial justice, equality, and inclusion.

This book argues that the Enlightenment was a golden age for the philosophy of body, and for efforts to integrate coherently a philosophical concept of body with a mathematized theory of mechanics. Thereby, it articulates a new framing for the history of 18th-century philosophy and science. It explains why, more than a century after Newton, physics broke away from philosophy to become an autonomous domain. And, it casts fresh light on the structure and foundations of classical mechanics. Among the figures (...) studied are Malebranche, Leibniz, Du Châtelet, Boscovich, and Kant, alongside d’Alembert, Euler, Lagrange, Laplace and Cauchy. (shrink)

A testimony is somebody else’s reported experience of what has happened. It is an indispensable source of knowledge. It only gives us historical cognition, however, which stands in a complex relation to rational or philosophical cognition: while the latter presupposes historical cognition as its matter, one needs the architectonic “eye of a philosopher” to select, interpret, and organize historical cognition. Kant develops this rationalist theory of testimony. He also practices it in his own work, especially while theorizing about race as (...) a subject of natural philosophy. In three dedicated essays on this subject, he treats race from the standpoint of a philosophical investigator of nature (Naturforscher), who (as Kant puts it in the first Critique) learns from nature “like an appointed judge who compels witnesses to answer the questions he puts to them.” This view underwrites Kant’s use of travel reports (a type of testimony) in developing and defending his theory of race.

This article discusses the opposition of neurosciences of moral judgement to moral philosophy, shedding light on the political meaning of the thesis according to which a science of morality is possible, or already real, and would demonstrate that rights’ recognition equates to a cognitive error. It furthermore presents some theoretical contributions offered by Kant’s moral doctrine – on condition that one avoids providing an unfounded and caricatural account in order to make it the paradigm of armchair philosophy – about the (...) role of intuition and reasoning in formulating moral judgements and of mental experiments on moral dilemmas.

Leibniz and Kant were heirs of a biblical theistic tradition which viewed miraculous activity in the world as both possible and actual. But both were also deep explanatory rationalists about the natural world: more committed than your average philosophical theologian to its thoroughgoing intelligibility. These dual sympathies—supernaturalist religion and empirical rationalism—generate a powerful tension across both philosophers’ systems, one that is most palpable in their accounts of empirical miracles—that is, events in nature that violate one or more of the natural (...) laws. The primary goal of this chapter is to exhibit their respective efforts to resolve this tension, and to show how Kant’s noumenal ignorance doctrine allows him to set aside some key difficulties that Leibniz’s model leaves unresolved. The chapter concludes with the unorthodox suggestion that both systems leave conceptual space for the idea that finite free beings, rather than just God, can produce empirical miracles. (shrink)

In the Second Analogy, Kant argues that every event has a cause. It remains disputed what this conclusion amounts to. Does Kant argue only for the Weak Causal Principle that every event has some cause, or for the Strong Causal Principle that every event is produced according to a universal causal law? Existing interpretations have assumed that, by Kant’s lights, there is a substantive difference between the two. I argue that this is false. Kant holds that the concept of cause (...) contains the notion of lawful connection, so it is analytic that causes operate according to universal laws. He is explicit about this commitment, not least in his derivation of the Categorical Imperative in Groundwork III. Consequently, Kant’s move from causal rules to universal laws is much simpler than previously assumed. Given his commitments, establishing the Strong Causal Principle requires no more argument than establishing the Weak Causal Principle. (shrink)

Leibniz, and many following him, saw the Principle of Sufficient Reason (PSR) as pivotal to a scientific (demonstrated) metaphysics. Against this backdrop, Kant is expected to pay close attention to PSR in his reflections on the possibility of metaphysics, which is his chief concern in the Critique of Pure Reason. It is far from clear, however, what has become of PSR in the Critique. On one reading, Kant has simply turned it into the causal principle of the Second Analogy. On (...) a different reading, PSR is but the supreme principle of reason, which roughly states that, if the conditioned is given, so is the unconditioned. On my reading, PSR appears in the guises of both the causal principle and the supreme principle. This twofold specification, I argue, is key to understanding (i) Kant’s allegations that past metaphysicians failed to prove PSR, (ii) his own Critical account of the possibility of metaphysics in both of its parts (ontology and metaphysics proper), and (iii) his nuanced answer to the contentious question about the relation between physical inquiry and metaphysical reasoning about nature (both being quests for reasons).

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)

Over the last two decades there has been a significant increase of interest in Schelling’s philosophy, and in particular his philosophy of nature. However, even the most generous of Schelling’s interpreters are confused by one of Schelling’s key theses: his view that nature as a whole (including non-living nature) is “organized,” and his related rejection of the hard-and-fast distinction between living and non-living. My aim is to offer an explanation of these two related points. Given that Schelling regards all of (...) nature as organized, it makes most sense to begin with the basic stuff of nature—matter. For if we can understand how matter can be organized, then we can also understand how non-living material beings are also organized. Accordingly, I focus on Schelling’s first work in the philosophy of nature, the 1797 Ideen zu einer Philosophie der Natur (Ideas for a Philosophy of Nature), where he deals with matter most directly and challenges mechanistic accounts of matter. I show that the crucial influence on the Ideen was not (as many interpretations have it) Fichte, but Kant, and explicate how and why Schelling departs from Kant’s understanding of both matter and organization. Finally, I will briefly point to the ways in which Schelling’s understanding of organization can be brought to bear on current questions in theoretical biology. (shrink)

This paper will make the case that we can find in Kant’s Second Analogy a substantive response to Hume’s argument on induction. This response is substantive insofar as it does not merely consist in independently arguing for the opposite conclusion, but rather, it identifies and exploits a gap in this argument. More specifically, Hume misses the possibility of justifying the uniformity of nature as a synthetic a priori proposition, which Kant looks to establish in the Second Analogy. Note that the (...) focus on the paper is on Kant’s identification of the form that a solution to Hume’s inductive scepticism must take. In making this point, my paper will look to establish two lemmas: Kant identifies synthetic a priori judgments as a means of justifying metaphysical knowledge in a way that circumvents Hume’s dichotomy between matters of fact and relations of ideas; the Second Analogy looks to establish the uniformity of nature of as a synthetic a priori proposition. However, my paper generally abstains from the question of the tenability of Kant’s argument in the Second Analogy. Doing justice to this latter discussion would require more space than I am able to offer here. My paper therefore has a conditional bearing on the philosophical issue of inductive scepticism. If one believes Kant’s Second Analogy to be philosophically cogent, then Kant offers a successful justification of induction against Hume’s scepticism. If not, then at least one can still admire Kant’s identification of the gap in Hume’s argument, which, to a degree, can be exploited independently of Kant’s system. (shrink)

Kant’s Third Analogy of Experience seeks to establish the mutual interaction of all objects of experience as a transcendental condition on the possibility of our experience of coexistence, and by extension of any cohesive or unified experience. Of Kant’s three Analogies, the Third has received both the least attention and the most criticism. I present an analysis of the Third Analogy focussing on the spatial aspect of Kant’s argument. I examine the interrelated nature of the forms of inner and outer (...) sense in the Third Analogy, linking this to their function in the Transcendental Deduction and subsequently turning to look at the problem posed by Kant’s argument regarding empty space in the Third Analogy. I present a tentative interpretation whereby the Third Analogy establishes a mutual dependence between space as a singular pure intuition, and the instantiation of the category of community in experience.

This article explains Kant’s claim that sciences must take, at least as their ideal, the form of a ‘system’. I argue that Kant’s notion of systematicity can be understood against the background of de Jong & Betti’s Classical Model of Science (2010) and the writings of Georg Friedrich Meier and Johann Heinrich Lambert. According to my interpretation, Meier, Lambert, and Kant accepted an axiomatic idea of science, articulated by the Classical Model, which elucidates their conceptions of systematicity. I show that (...) Kant’s critique of the mathematical method is compatible with his adherence to this axiomatic conception of science. I further show that systematicity furthers traditionally accepted logical ideals of scientific knowledge, which explains why Meier and Kant think that sciences must be ‘systematic’. (shrink)

It is widely held that, in his pre-Critical works, Kant endorsed a necessitation account of laws of nature, where laws are grounded in essences or causal powers. Against this, I argue that the early Kant endorsed the priority of laws in explaining and unifying the natural world, as well as their irreducible role in in grounding natural necessity. Laws are a key constituent of Kant’s explanatory naturalism, rather than undermining it. By laying out neglected distinctions Kant draws among types of (...) natural law, grounding relations, and ontological levels, I show that his early works present a coherent and sophisticated laws-first account of the natural order.

Kant suggested that Newton’s Inverse Square Law (ISL) determines the dimensions of space to be three. Much has been written in the philosophical literature about Kant’s suggestion, including specific arguments attempting to link the ISL to three-dimensionality. In this paper, we explore one such argument and demonstrate that it fails to support the link Kant purports to make between the ISL and the three-dimensionality of space. At best, the link that can be made is between the ISL and symmetry.

The problem of synthetic judgements touches on the question of whether philosophy can draw independent statements about reality in the first place. For Kant, the synthetic judgements a priori formulate the conditions of the possibility for objectively valid knowledge. Despite the principle fallibility of its statements, modern science aims for objective knowledge. This gives the topic of synthetic a priori unbroken currency. This paper aims to show that a modernized version of transcendental philosophy, if it is to be feasible at (...) all, must “bid farewell” to the concept of being “free of empiricism” or the “purity” of the a priori. Approaches to this end can already been found in Kant’s reflections on non-pure synthetic knowledge. Moreover, the a priori validity of knowledge does not exclude the possibility that it can be discovered empirically. In keeping with Kant, Fries and Nelson anticipated this separation (usually first attributed to Reichenbach) between the validity and discovery context of knowledge and pointed out that the a priori could be discovered empirically, but never proven. There are currently still good reasons why transcendental philosophical concepts are of fundamental importance for modern science, although it must not be overlooked that even within the framework of a modernized transcendental philosophy, several unsolved problems remain or are raised. For example, the irredeemability of the universal validity and necessary claims of the a priori, the problem of a clear demarcation between the phenomenal and noumenal world. Moreover, the “beautiful structure” or the Kantian system, which constituted its persuasive power, is lost. (shrink)

The metaphysical “Law of Continuity of Alterations” says that whenever an object alters from one state to another, it passes through a continuum of intermediate states. Kant treated LCA as a transcendental law of understanding. The primary purpose of the paper is to reconstruct and evaluate Kant’s three arguments for LCA. All three are found to be inadequate. However, a secondary goal of the paper is to show that LCA would have more naturally been construed as a regulative principle of (...) reason. I conclude with some remarks about how this could work.

I argue that Kant has developed a broad systematic account of the architectonic functionality of pure reason that can be used and advanced in contemporary contexts. Reason, in the narrow sense, is responsible for the picture of a well-ordered universe of science consisting of architectonic ideas of science, sciences and parts of sciences. In the first section (I), I show what Kant means by the architectonic ideas by explaining and interrelating the concepts of (a) the faculty of reason, (b) ideas (...) (as principles), (c) method, and (d) sciences of reason. Thereafter (II), I think through his holistic understanding of science and scientific progress and suggest differentiating between four levels of use of architectonic ideas, drawing on the metaphor of a well-structured universe as imagined by Kant in his work on the Universal Natural History and Theory of the Heavens. I also claim that each possible idea of reason can be (apart from its primary function) additionally regarded as a fourth-level architectonic concept when explicitly conceived as an object of (e. g. philosophical) studies, i. e. from a mere methodological perspective. In the final section (III), I unveil the potential of Kant’s theory by pointing out how this architectonic methodological function of pure reason is tacitly used in Karl-Otto Apel’s contemporary philosophical research programme. You can get the official version of the paper and the whole issue (open access) by clicking on the attached link. (shrink)

In this paper I develop an account of Fichte’s conception of philosophical construction. Following the latter’s definition of philosophy as the ‘science of science’, philosophy is to be understood as a normative theory of what should qualify as science. In order to ground scientific knowledge-production as such, philosophy itself has to acquire a scientific method, through the application of which the constitution of scientific knowledge is secured. In systematic continuity to Kant’s account of geometrical construction, Fichte develops a philosophical method (...) that exploits the special epistemic conditions of performativity. Construction is then defined as an experimental, self-reflexive performance that exemplifies consciousness. Throughout its acts of exemplification this reflexive kind of self-observation yields a particular type of experience, which ultimately satisfies the Science of Knowledge’s demand for certainty, that is intellectual intuition.

Kant speaks repeatedly about the relations between ends or aims and scientific research, but the topic has mostly been ignored. What is the role of ends, especially practical ones, in his views on science? I will show that while Kant leaves ample space for recognizing a function of ends both in the definition and the pursuit of inquiry, and in the further practical application of scientific cognition, he does not claim that science is simply an instrument for achieving practical ends. (...) I explain his complex conception, pointing out that Kant argues that the sciences require ends for their very definition, that ends come in fundamentally different kinds, that the relation between science and ends requires the rational determination and hierarchization of all our ends, with “wisdom” as the highest, and that this determination and hierarchization – which ought to be done by metaphysics – has itself to be carried out in a “scientific way”. I show further that Kant gives sui generis weight to the epistemic aims and standards of science and to the autonomy of science from our practical lives. This places his position between separatism and anti-separatism with regard to the relation between science and our ends or values. (shrink)

Kant and Heidegger argue that our subjectivity escapes scientific explanation, while also providing the conditions that enable it. This understanding of the relationship between subjectivity and science places limits on the explanatory scope of the sciences. But what makes transcendental reflection on the structure of subjectivity possible in the first place? Fink argues that transcendental philosophy encounters its own limits in attempting to characterize its own conditions of possibility. I argue that the limits of science and transcendental philosophy entail that (...) nature cannot be conceived as a specific object, or as a totality of objects in the world, but only as the ontological ground of phenomenal manifestation in general. Nature is not identical with anything discoverable in either science or phenomenology; it is, rather, the origin from which discovery of phenomena proceeds. (shrink)

Ernst Mayr argued that the emergence of biology as a special science in the early nineteenth century was possible due to the demise of the mathematical model of science and its insistence on demonstrative knowledge. More recently, John Zammito has claimed that the rise of biology as a special science was due to a distinctive experimental, anti-metaphysical, anti-mathematical, and anti-rationalist strand of thought coming from outside of Germany. In this paper we argue that this narrative neglects the important role played (...) by the mathematical and axiomatic model of science in the emergence of biology as a special science. We show that several major actors involved in the emergence of biology as a science in Germany were working with an axiomatic conception of science that goes back at least to Aristotle and was popular in mid-eighteenth-century German academic circles due to its endorsement by Christian Wolff. More specifically, we show that at least two major contributors to the emergence of biology in Germany—Caspar Friedrich Wolff and Gottfried Reinhold Treviranus—sought to provide a conception of the new science of life that satisfies the criteria of a traditional axiomatic ideal of science. Both C.F. Wolff and Treviranus took over strong commitments to the axiomatic model of science from major philosophers of their time, Christian Wolff and Friedrich Wilhelm Joseph Schelling, respectively. The ideal of biology as an axiomatic science with specific biological fundamental concepts and principles thus played a role in the emergence of biology as a special science. (shrink)

Ecology arguably has roots in eighteenth-century natural histories, such as Linnaeus's economy of nature, which pressed a case for holistic and final-causal explanations of organisms in terms of what we'd now call their environment. After sketching Kant's arguments for the indispensability of final-causal explanation merely in the case of individual organisms, and considering the Linnaean alternative, this paper examines Kant's critical response to Linnaean ideas. I argue that Kant does not explicitly reject Linnaeus's holism. But he maintains that the indispensability (...) of final-causal explanation depends on robust modal connections between types of organism and their functional parts; relationships in Linnaeus's economy of nature, by contrast, are relatively contingent. Kant's framework avoids strong metaphysical assumptions, is responsive to empirical evidence, and can be fruitfully compared with some contemporary approaches to biological organization. (shrink)

In Kant's Critique of Judgment, his exploration of how something like life (organized matter) can appear to the faculties of a finite consciousness makes life as possible as it is impossible. A passing reference Kant makes to the idea that every organ of an organism can be seen as a parasite is taken as a lever to deconstruct his notion of organized beings as forming an ultimately coherent nature (an ethicoteleological whole). This reading is placed alongside Paul de Man's deconstruction (...) of the sublime as Augenschein and Darstellung von Ideen to show that the unity of the third critique, sometimes viewed as a fractured work, comes from the similar failures of sublimity and purposive organization. This reading is offered to suggest the importance of biodeconstruction for an engagement with the history and present of thought about the natural sciences. (shrink)

The antinomy of teleological judgment has increasingly been understood as a conflict between regulative principles. But it is not clear why regulative principles can be in conflict at all, since Kant otherwise takes the realization that two conflicting principles are regulative to be sufficient to resolve an antinomy. I argue that in Kant’s view regulative principles do not conflict with one another only if they are reducible to reason’s interest in systematicity. Given that the principles of this antinomy do conflict, (...) they must not be reducible to reason’s interest in systematicity. I argue that teleology is thus not reducible to reason’s interest because it is fundamentally unlawful. I then use this irreducibility to account for Kant’s appeal to the supersensible in this context. (shrink)

Recent literature on Kant’s Opus postumum has typically focused on two parts of the drafts: the ether proofs and the Selbstsetzungslehre. Eckart Förster’s interpretation is representative of this tendency and, moreover, presents the Selbstsetzungslehre as the culmination of Kant’s late project. By contrast, I argue that the drafts of fascicles X/XI, written in between the ether proofs and the Selbstsetzungslehre, are of primary importance for understanding the Opus postumum. Through a close reading of a page from fascicle XI, I show (...) that Kant attempts to resolve problems internal to the Selbstsetzungslehre and the ether proofs by presenting a transition from the former to the latter. I advocate a renewed appreciation of the centrality of fascicles X/XI, insofar as the Opus postumum drafts aspire to a science of transition. (shrink)

The theory of space-time developed in Kant’s Critique of Pure Reason and his Metaphysical Foundations of Natural Science is connected to Leonhard Euler’s proof of invariance under Galilean transformations in the “On Motion in General” of the latter’s 1736 Analytical Mechanics. It is argued that Kant, by using the Principle of Relativity that is the output of Euler’s proof as an input to his own proof of the kinematic parallelogram law, makes essential use of absolute simultaneity. This is why, in (...) the Transcendental Aesthetic, he observes that “our theory of time explains as much a priori knowledge as the general theory of motion displays.” In conclusion, it is shown that the same proof-method, under a different definition of simultaneity, leads to the parallelogram law of the “Kinematic Part” of Einstein’s 1905 “On the Electrodynamics of Moving Bodies”.

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.

it is common to praise the beauty of theories, the elegance of proofs, and the pleasing simplicity of explanations. We may admire, for example, the beauty of Einstein’s theory of general relativity, the simplicity of Darwin’s idea of natural selection, and the elegance of a geometrical proof of Pythagoras’s theorem. Aesthetic judgments such as these have much currency among scientists, and they are employed in the search for knowledge more broadly. But while the use of aesthetic judgments in science is (...) widespread, it is not uncontroversial.1 On one side, such judgments are often inspired by the Platonic vision that beauty and truth are ultimately one. As Henri Poincaré saw it, science is the “disinterested pursuit... (shrink)

This paper takes a less trodden path in its approach to Kant’s philosophy of religion. Rather than a detailed study of his mature works on the subject, some of his pre-Critical works are examined. These reveal what I hold to be four foundations which remain unchanged through Kant’s philosophical career and thus act to hold up his later work on the subject. The main body of the paper is presented in two parts. In the first, we see that Kant finds (...) that in addition to evil as limitation, there is now evil which is ontologically positive. The second part is devoted to Kant’s considerations of what was termed “physical evil”. He finds that this is neither an evil nor any form of divine punishment but rather those consequences of the laws of nature which are harmful to humans. Further, God does not intervene with the workings of these laws of nature which He has put in place but guarantees their continuity. However, it will be shown that such non-interference is problematic for Kant’s mature stance on miracles. (shrink)

Previous discussions of Kant’s influence on German biology have resulted in contradictory accounts. Zammito argues both that Kant could not have influenced German biology because his account is fundamentally incompatible with the presuppositions of biological naturalism, and biology only emerged because biologists misunderstood Kant’s philosophy. I argue that his account exposes an important difficulty when considering Kant’s influence on the development of biology, since it correctly identifies a fundamental incompatibility between biological naturalism and Kant. However, this does not demonstrate that (...) Kant could not have been influential on the development of biology. Instead, I propose a broader conception of influence that includes both intentional and non-intentional forms of misunderstanding. I examine Kant’s influence on the development of biology in the British Isles. Both in the history of science and contemporary research, the literature tends to focus on Kant’s ‘Critique of Teleological Judgment’ as this is where Kant discusses how biological entities require us to judge them as if they possessed the properties of self-organization, growth and reproduction. I argue that Kant’s influence on biology in the British Isles originates from his account of scientific methodology in his earlier work, the Critique of Pure Reason. Kant’s account was influential on William Whewell. Kant argued that the unity of science was merely a presupposition for scientific enquiry, whereas Whewell argued this unity was an inherent property of the world that science was discovering. I argue that Whewell intentionally misinterpreted aspects of Kant’s philosophy to develop a more naturalistic theory of science. Whewell was influential on the development of Darwin’s scientific methodology in the Origin as he argues for the correctness of his theory on the basis that it displays consilience. Whewell’s account of science was not only influential for the development of biology but also for more recent accounts of scientific methodology and reductivist accounts of science. I argue that this dual philosophical-historical approach provides the basis for a richer, more adequate understanding of how Kant’s philosophy has continued to exert a strong though often unrecognised influence on developments in biological theory such as immunology and contemporary accounts of biological autonomy. All the same that influence is highly problematic because of the original incompatibility between transcendental idealism and biological naturalism. Understanding how aspects of Kant’s philosophy are intertwined with both the development of biology and contemporary philosophy of biology allows us to assess the conjoint costs and benefits of the synthesis between Kant’s philosophy and philosophy of biology.

This paper examines whether Kant’s Critical philosophy offers resources for a conception of empirical psychology as a theoretical science in its own right, rather than as a part of applied moral philosophy or of pragmatic anthropology. In contrast to current interpretations, this paper argues that Kant’s conception of inner experience provides relevant resources for the theoretical foundation of scientific psychology, in particular with respect to its subject matter and its methodological presuppositions. Central to this interpretation is the regulative idea of (...) the soul, which supplies principles of systematicity at different levels. Firstly, the idea defines the way in which we must reflect on mental beings, i.e., those beings that fall in the domain of psychology. Secondly, it provides a principle for the unification of a systematic body of psychological laws. In consequence, by approaching the object of psychology from the perspective of the self-conscious subject, who––in virtue of being capable of inner experience––first constitutes a psychological reality, Kant’s theory offers an attractive alternative to reductionist conceptions of psychology.

This paper examines Du Châtelet’s and Kant’s responses to the famous vis viva controversy – Du Châtelet in her Institutions Physiques (1742) and Kant in his debut, the Thoughts on the True Estimation of Living Forces (1746–49). The Institutions was not only a highly influential contribution to the vis viva controversy, but also a pioneering attempt to integrate Leibnizian metaphysics and Newtonian physics. The young Kant’s evident knowledge of this work has led some to speculate about his indebtedness to her (...) philosophy. My study corrects such speculations as well as misunderstandings of the Living Forces. This corrective result has implications for how to investigate Kant’s relation to the ever-evolving landscape of Leibniz exegeses. (shrink)

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.

Kantian philosophy of space, time and gravity is significantly affected in three ways by particle physics. First, particle physics deflects Schlick’s General Relativity-based critique of synthetic a priori knowledge. Schlick argued that since geometry was not synthetic a priori, nothing was—a key step toward logical empiricism. Particle physics suggests a Kant-friendlier theory of space-time and gravity presumably approximating General Relativity arbitrarily well, massive spin-2 gravity, while retaining a flat space-time geometry that is indirectly observable at large distances. The theory’s roots (...) include Seeliger and Neumann in the 1890s and Einstein in 1917 as well as 1920s–1930s physics. Such theories have seen renewed scientific attention since 2000 and especially since 2010 due to breakthroughs addressing early 1970s technical difficulties. Second, particle physics casts additional doubt on Friedman’s constitutive a priori role for the principle of equivalence. Massive spin-2 gravity presumably should have nearly the same empirical content as General Relativity while differing radically on foundational issues. Empirical content even in General Relativity resides in partial differential equations, not in an additional principle identifying gravity and inertia. Third, Kant’s apparent claim that Newton’s results could be known a priori is undermined by an alternate gravitational equation. The modified theory has a smaller symmetry group than does Newton’s. What Kant wanted from Newton’s gravity is impossible due its large symmetry group, but is closer to achievable given the alternative theory. (shrink)

Kant’s first antinomy in the Critique of Pure Reason deals with the question of the size of the world. The temporal portion of the problem, on which I will focus in this paper, concerns the question of whether the world has a beginning in time or whether it exists eternally. Kant is sometimes understood as arguing that since neither one of the conflicting options can be confirmed, one needs to reject the common mistake of both opponents, namely, that we know (...) the world as a thing in itself, and embrace instead Kant’s transcendental idealism. In view of modern cosmology, Kant’s resolution of the first antinomy may appear outdated. Modern cosmological theories, after all, do suggest that the world evolved from a singular point by a big bang or through a cycle of successive expanding and contracting phases. I wish to argue in this paper that Kant’s analysis of the first antinomy does not involve questions of confirmability and that its lessons apply to modern cosmology as well. Kant’s analysis challenges the view that the world as a whole is a proper object for human investigation, but it does not reject the legitimacy of the cosmological project of explaining the current state of the universe and its evolution in terms of earlier events in the history of the world. It merely shows that modern theories are misguided only insofar as they attempt to affirm that the singular point is the absolute beginning of the world or that the cycle of expansion and contraction is ultimately infinite. Thus, Kant does not deny science as a legitimate avenue of research. He rather keeps cosmology from sliding into the dogmatic paths of traditional cosmological speculations, which purported to account for the absolute origin of the world by means of theological and metaphysical considerations.

Kant argues in the Critique of the Teleological Power of Judgment that the first stage in resolving the problem of teleology is conceiving it correctly. He explains that the conflict between mechanism and teleology, properly conceived, is an antinomy of the power of judgment in its reflective use regarding regulative maxims, and not an antinomy of the power of judgment in its determining use regarding constitutive principles. The matter in hand does not concern objective propositions regarding the possibility of objects (...) or actual features of certain objects, namely, organisms. It is rather a methodological issue as to the appropriate way to explain the generation, development, and function of organisms. Taken in this manner as subjective maxims guiding the explanation and inquiry of organisms, the principles of mechanism and teleology need not necessarily be seen as contradictorily opposed but instead can be combined in the study of organisms. This, however, is not enough to complete the analysis of the antinomy of the teleological power of judgment. In order to show that there is an antinomy in this case, Kant has to establish that both seemingly conflicting maxims are necessary and natural to the human mind. He does it by grounding them in the ‘special character’ or peculiarity (Eigentümlichkeit) of the human understanding. However, it is not entirely clear just what exactly this peculiarity of the human understanding is. Paul Guyer argues that Kant suggests two different accounts of the peculiarity of the human intellect. According to one account, this peculiarity consists in the fact that our understanding forms general concepts and according to another, in its propensity to proceed from the parts to the whole. I will argue in this paper that Kant puts forward a single account, in which the combination of these two features demonstrate the peculiarity of the human understanding manifested in the encounter with organisms. This account explains the necessity of the regulative maxims of mechanism and teleology, and thus completes Kant’s analysis of the antinomy of the teleological power of judgment. (shrink)

The article is the introduction to the Russian translation of the preface and Book I of William Whewell’s classic work “Novum Organon Renovatum”. In his theory for the philosophy of science, Whewell of­fers a conception, which radically differs from a positivist or an inductivist models of science – the most influential doctrines of his time. Presupposing that the scientific activity is impossible without acceptance of a metaphysical doctrine, Whewell goes against the contemporary tendencies in phi­losophy. Nevertheless, eclecticism of his views (...) on certain issues does not allow us to classify him as a representative of any particular philosophical “camp”. In the article, the author analyzes the “a priori” component in the system of the philosophy of science by William Whewell and the influence of Im­manuel Kant’s conception of a priori on it. (shrink)
