In the Critique of Pure Reason, Kant uses the term “logic” in a bewildering variety of ways, at times making it close to impossible to determine whether he is referring to (among others) general logic, transcendental logic, transcendental analytic, a "special" logic relative to a specific science, a "natural" logic, a logic intended for the "learned" (Gelehrter), some hybrid of these logics, or even some still-more abstract notion that ranges over all of these uses. This paper seeks to come to (...) grips with Kant's complex use of "logic." Kant is standardly regarded as saying that since Aristotle, there need be no more concern about logic as a discipline or a field of study, and that Aristotle (with some minor embellishments, in terms of presentation) is the last word in logic. I argue here that, in spite ofHegel, Peirce, Strawson, and others, one must take into consideration Kant’s sophisticated critique of Aristotle’s logic in order to see Kant’s own conception of logic in contrast to that of Aristotle’s. In this way, Kant's strategy in the First Critique—grounded as it is in logic—becomes more plausible, defensible, and, consequently, more attractive. (shrink)

A look at the dynamical concept of space and space-generating processes to be found in Kant, J.F. Herbart and the mathematician Bernhard Riemann's philosophical writings.

Kant’s three Analogies of Experience, in his Critique of Pure Reason, represent a highly condensed attempt to establish the metaphysical foundations of Newtonian physics. His strategy is to show that the organization of experience in terms of a world of enduring substances undergoing mutual causal interaction is a necessary condition of the temporal ordering even of one’s own subjective states, and thus of coherent experience itself. In his Third Analogy—an examination of the necessary conditions of judgments of simultaneous existence—he argues (...) that certain conceptual presuppositions consistent with Newtonian physics are necessary to time-awareness. His argument, however, appears to be undermined by conventionalism in natural science generally, and by the conventionality of simultaneity in particular. In this paper I discuss Kant’s claims in light of contemporary relativity theory. I suggest that, while his project is obsolete in major respects, there may still be useful insights into time-awareness to be drawn from his work. (shrink)

Kant is well known for his restrictive conception of proper science. In the present paper I will try to explain why Kant adopted this conception. I will identify three core conditions which Kant thinks a proper science must satisfy: systematicity, objective grounding, and apodictic certainty. These conditions conform to conditions codified in the Classical Model of Science. Kant’s infamous claim that any proper natural science must be mathematical should be understood on the basis of these conditions. In order to substantiate (...) this reading, I will show that only in this way it can be explained why Kant thought (1) that mathematics has a particular foundational function with respect to the natural sciences and (2) as such secures their scientific status.

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.

In Language, Logic, and Experience, Michael Luntley successfully employs a Kantian-style transcendental argument to refute Michael Dummett’s anti-realist view that we are incapable of grasping “recognition-transcendent” truth-conditions. But he also contends that his own purified version of antirealism is immune to thi s sort of attack. This version is purified because it is concerned solely with the question of whether a given statement possesses a determinate truth value, and thus with whether the reality it is about exists determinately. I show (...) that Kant’s original version of the argument (in the “Transcendental Analytic”) does in fact amount to a refutation of Luntleyan anti-realism. In particular, it demonstrates that the determinate existence of all past and present naturalistic states and events is a necessary condition of thought. Since Luntleyan anti-realism entails that many such states and events are indeterminate, it must be rejected. (shrink)

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.

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)

From Kant’s first published work to recent articles in the physics literature, philosophers and physicists have long sought an answer to the question, why does space have three dimensions. In this paper, I will flesh out Kant’s claim with a brief detour through Gauss’ law. I then describe Büchel’s version of the common argument that stable orbits are possible only if space is three-dimensional. After examining objections by Russell and van Fraassen, I develop three original criticisms of my own. These (...) criticisms are relevant to both historical and contemporary proofs of the dimensionality of space (in particular, a recent one by Burgbacher, F. Lämmerzahl, C., and Macias). In general I argue that modern “proofs” of the dimensionality of space have gone off track. (shrink)

I attempt a reconstruction of Kant's version of the causal theory of time that makes it appear coherent. Two problems are at issue. The first concerns Kant's reference to reciprocal causal influence for characterizing simultaneity. This approach is criticized by pointing out that Kant's procedure involves simultaneous counterdirected processes-which seems to run into circularity. The problem can be defused by drawing on instantaneous processes such as the propagation of gravitation in Newtonian mechanics. Another charge of circularity against Kant's causal theory (...) was leveled by Schopenhauer. His objection was that Kant's approach is invalidated by the failure to deliver non-temporal criteria for distinguishing between causes and effects. I try to show that the modern causal account has made important progress toward a successful resolution of this difficulty. The fork asymmetry, as based on Reichenbach's principle of the common cause, provides a means for the distinction between cause and effect that is not based on temporal order (if some preconditions are realized). (shrink)

Transcendental epistemology is an inquiry into conditions of human knowledge which reflect the structure of the human cognitive apparatus. The dependence thesis is the thesis that a proper investigation of such conditions must lean in important respects on the deliverances of science. I argue that Kant is right to object to the dependence thesis, but that the best objections to this thesis lead to the conclusion that the conditions of knowledge which Kant identifies are not, in any interesting sense, a (...) relection of the structure of the human cognitive apparatus.

A description and critique of aspects of Michael Friedman's latter day NeoKantian program in the philosophy of science. -/- .

This article is an investigation of parallel themes in Heinrich Hertz's philosophy science and Kant's theory of schemata, symbols and regulative ideas. It is argued that Hertz's "pictures" bears close similarities to Kantian "schemata", that is, they are rules linking concepts to intuitions and provide them with their meaning. Kant's distinction between symbols and schemata is discussed and related to Hertz's three pictures of mechanics. It is argued that Hertz considered his own picture of mechanics (the "hidden mass" picture) as (...) symbolic in a different way than the force and energy pictures. In the final part of the article it is described how Harald Høffding soon after the publication of Hertz's Principles of Mechanics developed a general theory of analogical reasoning, relying on the ideas of Hertz and Kant.

The aim of this paper is to argue that Kant's philosophy of biology has crucial implications for our understanding of his philosophy of history, and that overlooking these implications leads to a fundamental misconstruction of his views. More precisely, I will show that Kant's philosophy of history is modelled on his philosophy of biology due to the fact that the development of the human species shares a number of peculiar features with the functioning of organisms, these features entailing important methodological (...) characteristics. From this main claim will follow three further claims: (1) Kant's teleological view of history is not simply based on ethical considerations that have to do with the moral progress of the human species; rather, it stems from his conception of teleology as developed in his philosophy of biology. (2) Kant's philosophy of history allows for the practice of scientific history. In this sense, Kant's view of history is not merely teleological but involves a mechanical (and thus empirical) element. (3) Just as teleology is useful for furthering mechanical accounts of biological phenomena, teleological history is useful for scientific history. (shrink)

A growing number of commentators have, in recent years, noted the important affinities in the views of Immanuel Kant and Niels Bohr. While these commentators are correct, the picture they present of the connections between Bohr and Kant is painted in broad strokes; it is open to the criticism that these affinities are merely superficial. In this essay, I provide a closer, structural, analysis of both Bohr's and Kant's views that makes these connections more explicit. In particular, I demonstrate the (...) similarities between Bohr's argument, on the one hand, that neither the wave nor the particle description of atomic phenomena pick out an object in the ordinary sense of the word, and Kant's requirement, on the other hand, that both ‘mathematical’ (having to do with magnitude) and ‘dynamical’ (having to do with an object's interaction with other objects) principles must be applicable to appearances in order for us to determine them as objects of experience. I argue that Bohr's ‘complementarity interpretation’ of quantum mechanics, which views atomic objects as idealizations, and which licenses the repeal of the principle of causality for the domain of atomic physics, is perfectly compatible with, and indeed follows naturally from a broadly Kantian epistemological framework.

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

This paper concentrates on some aspects of the history of the analytic-synthetic distinction from Kant to Bolzano and Frege. This history evinces considerable continuity but also some important discontinuities. The analytic-synthetic distinction has to be seen in the first place in relation to a science, i.e. an ordered system of cognition. Looking especially to the place and role of logic it will be argued that Kant, Bolzano and Frege each developed the analytic-synthetic distinction within the same conception of scientific rationality, (...) that is, within the Classical Model of Science: scientific knowledge as cognitio ex principiis . But as we will see, the way the distinction between analytic and synthetic judgments or propositions functions within this model turns out to differ considerably between them. (shrink)

This essay considers the nature of conceptual frameworks in science, and suggests a reconsideration of the role played by philosophy in radical conceptual change. On Kuhn's view of conceptual conflict, the scientist's appeal to philosophical principles is an obvious symptom of incommensurability; philosophical preferences are merely “subjective factors” that play a part in the “necessarily circular” arguments that scientists offer for their own conceptual commitments. Recent work by Friedman has persuasively challenged this view, revealing the roles that philosophical concerns have (...) played in preparing the way for conceptual change, creating an enlarged conceptual space in which alternatives to the prevailing framework become intelligible and can be rationally discussed. If we shift our focus from philosophical themes or preferences to the process of philosophical analysis, however, we can see philosophy in a different and much more significant historic role: not merely as an external source of general heuristic principles and new conceptual possibilities, but, at least in the most important revolutionary developments, as an objective tool of scientific inquiry. I suggest that this approach offers some insight into the philosophical significance of Newton's and Einstein's revolutionary work in physics, and of the interpretation of their work by (respectively) Kant and the logical positivists. It also offers insight into the connections between modern philosophy of science and some traditional philosophical concerns about the nature of a priori knowledge. (shrink)

In the second part of the Critique of Judgment, Immanuel Kant provides a transcendental analysis of the bases of our right to employ teleological conceptions in biology. A living organism exemplifies the conception of a natural end insofar as the organization of the parts to form a whole is the result of a process in which the organism is both cause and effect of itself. Kant’s analysis of the concept of a natural purpose is guided, in part, by his general (...) theory of logic. By examining the manner in which the logical modes of relation are used as a basis for analyzing the concept of a natural purpose, I hope to accomplish two goals: (1) to compare Kant’s analysis of the category of community to the analysis of the concept of a natural purpose; (2) to evaluate some of the strengths and weaknesses ofKant’s account of community and natural purpose; (3) to consider one criticism of Kant’s use of the logical form of the disjunctive as a basis for the analysis of these conceptions that is developed by Charles Sanders Peirce. Peirce indicates that Darwin’s theory of biological evolution was one of the primary causes that led him revisit Kant’s logic and his analysis of the categories of relation. (shrink)

Popper uses the "Humean challenge" as a justification for his falsificationism. It is claimed that in his basic argument he confuses two different doubts: (a) the Humean doubt (Popper's problem of induction), and (b) the "Popperean" doubt whether - presupposing that there are laws of nature - the laws we accept are in fact valid. Popper's alleged solution of the problem of induction does not solve the problem in a straightforward way (as Levison and Salmon have remarked before). But if (...) Popper's solution of the Humean challenge is re-interpreted as being close to Kant's it makes sense. Even though Popper explicitly rejects Kant's synthetic judgements a priori, it is claimed here that this is so because he misinterprets Kant's argument. If he had understood Kant correctly he should have been a modern "Kantianer"! (shrink)

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

Marco Buzzoni has presented a Kantian account of thought experiments in science as a serious rival to the current empiricist and Platonic accounts. This paper takes the first steps of a comprehensive assessment of this account in order to further the more general discussion of the feasibility of a Kantian theory of scientific thought experiments. Such a discussion is overdue. To this effect the broader question is addressed as to what motivates a Kantian approach. Buzzoni's account and the assessment developed (...) in this paper are warranted by the fact that the history of philosophical inquiry into thought experiments is deeply interwoven with Kant's philosophy. This history will be depicted here for the first time in more comprehensive terms to contextualize Buzzoni's account in historical and systematic perspective. (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.

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

Skeptical problems arising for Kant's version of transcendental idealism have been raised from Kant's own time to the present day. By focussing on how such problems originally arose in the wake of Kant's work, and on the first formulations of absolute idealism by Schelling, I argue that the skeptical problems in question ultimately depend on fundamental features of Kant's philosophy of natural science. As a result, Naturphilosophie and the organic conception of nature cannot easily be separated from the deep and (...) insightful response to these problems offered by absolute idealism. (shrink)

This paper considers the evolution of the problem of scientific rationality from Kant through Carnap to Kuhn. I argue for a relativized and historicized version of the original Kantian conception of scientific a priori principles and examine the way in which these principles change and develop across revolutionary paradigm shifts. The distinctively philosophical enterprise of reflecting upon and contextualizing such principles is then seen to play a key role in making possible rational intersubjective communication between otherwise incommensurable paradigms.

This book introduces a new approach to the issue of radical scientific revolutions, or "paradigm-shifts," given prominence in the work of Thomas Kuhn. The book articulates a dynamical and historicized version of the conception of scientific a priori principles first developed by the philosopher Immanuel Kant. This approach defends the Enlightenment ideal of scientific objectivity and universality while simultaneously doing justice to the revolutionary changes within the sciences that have since undermined Kant's original defense of this ideal. Through a modified (...) Kantian approach to epistemology and philosophy of science, this book opposes both Quinean naturalistic holism and the post-Kuhnian conceptual relativism that has dominated recent literature in science studies. Focussing on the development of "scientific philosophy" from Kant to Rudolf Carnap, along with the parallel developments taking place in the sciences during the same period, the author articulates a new dynamical conception of relativized a priori principles. This idea applied within the physical sciences aims to show that rational intersubjective consensus is intricately preserved across radical scientific revolutions or "paradigm-shifts and how this is achieved.

[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.

This book offers a detailed explanation and analysis of Kant’s empirical psychology and applies that analysis to thinking through several particular issues in Kant’s philosophy more generally. Kant is one of the most important and widely discussed philosophers today and Oxford has a long tradition of publishing excellent monographs on Kant's philosophy (including, for example, recent books such as Robert Hanna’s Kant, Science, and Human Nature and Robert Louden’s Kant's Impure Ethics).

"This book is a very important contribution to the study of the history of modern philosophy.

In an effort to account for our a priori knowledge of synthetic necessary truths, Kant proposes to extend the successful method used in mathematics and the natural sciences to metaphysics. In this paper, a uniform account of that method is proposed and the particular contribution of the ‘Copernican hypothesis’ to our knowledge of necessary truths is explained. It is argued that, though the necessity of the truths is in a way owing to the object's relation to our cognition, the truths (...) we come to know are fully objective, expressing necessary relations between properties. Kant's distinction between ‘phenomena’ and ‘noumena’ is shown to serve to properly restrict the scope of the necessity claims so that they do express necessary connections between properties.

: I distinguish two senses in which organisms are mechanically inexplicable for Kant. Mechanical inexplicability in the first sense is shared with artefacts, and consists in their exhibiting regularities irreducible to the regularities of matter. Mechanical inexplicability in the second sense is peculiar to organisms, consisting in the reciprocal causal dependence of an organism's parts. This distinction corresponds to two strands of thought in Aristotle, one supporting a teleological conception of organisms, the other supporting a conception of organisms as natural. (...) Recognizing this distinction helps us to see how a teleological conception of organisms is compatible with recent advances in biology. (shrink)

This major study of Kant provides a detailed examination of the development and function of the doctrine of transcendental illusion in his theoretical philosophy. The author shows that a theory of 'illusion' plays a central role in Kant's arguments about metaphysical speculation and scientific theory. Indeed, she argues that we cannot understand Kant unless we take seriously his claim that the mind inevitably acts in accordance with ideas and principles that are 'illusory'. Taking this claim seriously, we can make much (...) better sense of Kant's arguments and reach a deeper understanding of the role he allots human reason in science. (shrink)

The fundamental task of philosophy since the seventeenth century has been to determine whether the essential principles of both knowledge and action can be discovered by human beings unaided by an external agency. No one philosopher contributed more to this enterprise than Kant, whose Critique of Pure Reason (1781) shook the very foundations of the intellectual world. Kant argued that the basic principles of the natural sciences are imposed on reality by human sensibility and understanding, and thus that human beings (...) are also free to impose their own free and rational agency on the world. This volume is the only systematic and comprehensive account of the full range of Kant's writings available, and the first major overview of his work to be published in more than a dozen years.

Part of Kant’s legacy to Peirce was a lasting conviction that metaphysics is not irredeemable, but can and should be set “on the secure path of a science”. However, Peirce’s “scientific metaphysics”, unlike Kant’s, uses the method of science, i.e., of experience and reasoning; but requires close attention to experience of the most familiar kind rather than the recherché experience needed by the special sciences.

In Newtonian physics, all phenomena take place in absolute space, which is a fixed scenario, and are referred to absolute time, which rules all processes. Motion is governed by a set of basic differential equations, and it is possible, at least in principle, to deduce future events from present initial conditions.

It is occasionally claimed that the important work of philosophers, physicists, and mathematicians in the nineteenth and in the early twentieth centuries made Kant’s critical philosophy of geometry look somewhat unattractive. Indeed, from the wider perspective of the discovery of non-Euclidean geometries, the replacement of Newtonian physics with Einstein’s theories of relativity, and the rise of quantificational logic, Kant’s philosophy seems “quaint at best and silly at worst”.1 While there is no doubt that Kant’s transcendental project involves his own conceptions (...) of Newtonian physics, Euclidean geometry and Aristotelian logic, the issue at stake is whether the replacement of these conceptions collapses Kant’s philosophy into an unfortunate embarrassment.2 Thus, in evaluating the debate over the contemporary relevance of Kant’s philosophical project one is faced with the following two questions: (1) Are there any contradictions between the scientific developments of our era and Kant’s philosophy? (2) What is left from the Kantian legacy in light of our modern conceptions of logic, geometry and physics? Within this broad context, this paper aims to evaluate the Kantian project vis à vis the discovery and application of non-Euclidean geometries. Many important philosophers have evaluated Kant’s philosophy of geometry throughout the last century,3 but opinions with regard to the impact of non-Euclidean geometries on it diverge. In the beginning of the century there was a consensus that the Euclidean character of space should be considered as a consequence of the Kantian project, i.e., of the metaphysical view of space and of the synthetic a priori character of geometry. The impact of non-Euclidean geometries was then thought as undermining the Kantian project since it implied, according to positivists such.. (shrink)

Robert Hanna argues for the importance of Kant's theories of the epistemological, metaphysical, and practical foundations of the "exact sciences"--relegated to the dustbin of the history of philosophy for most of the 20th century.

In the Critique of Pure Reason Kant claims that he is offering a science of reason grounded on principles. Given Kant’s frequent but diverse use of the term “principle” throughout the work, it is unclear what exactly this term is supposed to signify, whether there are more or less fundamental principles and on what basis, and whether there is supposed to be some way in which the diverse instances of them are related to form a unified science of theoretical reason. (...) The aim of this paper is to offer a theory of Kant’s principles that will provide answers to these questions. First, the article clarifies what Kant understands by the term “principle” by briefly looking to his metaphysics lectures and then to the use of the term by two thinkers contemporary and influential to Kant—namely, Hume and Newton. The resulting hypothesis is that Kant conceives of principles in an Aristotelian fashion. While it is common to think of Kant’s theory of theoretical reason as uncovering the formal principles of cognition, the article next argues that such principles should be understood in the broader context of Kant’s teleological conception of theoretical reason, which contains also efficient transcendental principles, and whose unifying transcendental principle is a final cognitive aim. Finally, the article suggests that this teleological conception of reason has implications for a proper understanding of the highly disputed metaphysical results of the Critique. (shrink)

This paper outlines a new interpretation of an argument of Kant's for the existence of absolute space. The Kant argument, found in a 1768 essay on topology, argues for the existence of Newtonian-Euclidean absolute space on the basis of the existence of incongruous counterparts (such as a left and a right hand, or any asymmetrical object and its mirror-image). The clear, intrinsic difference between a left hand and a right hand, Kant claimed, cannot be understood on a relational view of (...) space - for in terms of the spatial relations of their parts, there is no difference to be found. Kant's argument has been interpreted by, among others, Graham Nerlich (in 1973, Hands, Knees and Absolute Space, The Journal of Philosophy). I briefly discuss Nerlich, and then offer a different reconstruction of the argument, one that appears to be closer to Kant's text. The reconstruction, however, essentially involves ascription of primitive identity to parts of space. Comparing the Kantian absolutist account of incongruous counterparts using primitive identity to the correct relationist account, I conclude that the absolutist account pays a heavy metaphysical price, without buying any genuine explanatory advantage over the relationist. I go on to examine recent suggestions that parity-non-conservation phenomena in quantum physics allow a stronger version of Kant's challenge to relationism. On closer examination, it turns out that here too the absolutist or substantivalist must be appealing to space parts with primitive identity in order to claim an advantage over relationists; and here too, I argue the substantivalist story really has no advantage over the correct relationist account.

Thomas Holden presents a fascinating study of theories of matter in the seventeenth and eighteenth centuries. These theories were plagued by a complex of interrelated problems concerning matter's divisibility, composition, and internal architecture. Is any material body infinitely divisible? Must we posit atoms or elemental minima from which bodies are ultimately composed? Are the parts of material bodies themselves material concreta? Or are they merely potentialities or possible existents? Questions such as these -- and the press of subtler questions hidden (...) in their amibiguities -- deeply unsettled philosophers of the early modern period. They seemed to expose serious paradoxes in the new world view pioneered by Galileo, Descartes, and Newton. The new science's account of a fundamentally geometrical Creation, mathematicizable and intelligible to the human inquirer, seemed to be under threat. This was a great scandal, and the philosophers of the period accordingly made various attempts to disarm the paradoxes. All the great figures address the issue: most famously Leibniz and Kant, but also Galileo, Hobbes, Newton, Hume, and Reid, in addition to a crowd of lesser figures. Thomas Holden offers a brilliant synthesis of these discussions and presents his own overarching interpretation of the controversy, locating the underlying problem in the tension between the early moderns' account of material parts on the one hand and the program of the geometrization of nature on the other.

I argue that we need not accept Quine's holistic conception of mathematics and empirical science. Specifically, I argue that we should reject Quine's holism for two reasons. One, his argument for this position fails to appreciate that the revision of the mathematics employed in scientific theories is often related to an expansion of the possibilities of describing the empirical world, and that this reveals that mathematics serves as a kind of rational framework for empirical theorizing. Two, this holistic conception does (...) not clearly demarcate pure mathematics from applied mathematics. In arguing against Quine, I present a formal account of applied mathematics in which the mathematics employed in an empirical theory plays a role that is analogous to the epistemological role Kant assigned synthetic a priori propositions. According to this account, it is possible to insulate pure mathematics from empirical falsification, and there is a sense in which applied mathematics can also be labeled as a priori. (shrink)

What is Albert Einstein’s place in the history of twentieth-century philosophy of science? Were one to consult the histories produced at mid-century from within the Vienna Circle and allied movements (e.g., von Mises 1938, 1939, Kraft 1950, Reichenbach 1951), then one would find, for the most part, two points of emphasis. First, Einstein was rightly remembered as the developer of the special and general theories of relativity, theories which, through their challenge to both scientific and philosophical orthodoxy made vivid the (...) need for a new kind of empiricism (Schlick 1921) whereby one could defend the empirical integrity of the theory of relativity against challenges 1 coming mainly from the defenders of Kant. Second, the special and general theories of relativity were wrongly cited as straightforwardly validating central tenets of the logical empiricist program, such as verificationism, and Einstein was wrongly represented as having, himself, explicitly endorsed those same philosophical principles. As we now know, logical empiricism was not the monolithic philosophical movement it was once taken to have been. Those associated with the movement disagreed deeply about fundamental issues concerning the structure and interpretation of scientific theories, as in the protocol sentence debate, and about the overall aims of the movement, as in the debate between the left and right wings 2 of the Vienna Circle over the role of politics in science and philosophy. Along with such differences went subtle differences in the assessment of Einstein’s legacy to logical empiricism. Philipp Frank–himself a dissenter from central points of right-wing Vienna Circle doctrine–deserves.. (shrink)

Without question, however, the crucial, formative, early intellectual experience of at least Schlick, Reichenbach, and Carnap, the experience that did most to give form and content to their emergent philosophies of science, was their engagement with relativity theory. Thus, after a few early writings on more general philosophical themes, Schlick first caught the attention of a (...) broader philosophical public with his 1915 essay, "Die philosophische Bedeutung des..

This article notes six advances in recent analytic Kant research: (1) Strawson's interpretation, which, together with work by Bennett, Sellars, and others, brought renewed attention to Kant through its account of space, time, objects, and the Transcendental Deduction and its sharp criticisms of Kant on causality and idealism; (2) the subsequent investigations of Kantian topics ranging from cognitive science and philosophy of science to mathematics; (3) the detailed work, by a number of scholars, on the Transcendental Deduction; (4) the clearer (...) understanding of transcendental idealism sparked by reactions to Allison's epistemic account; (5) the resulting need—prompted also by new studies of the thing in itself—to face up to the old question of the philosophical defensibility of such idealism; and (6) the active engagement with Kant's ethics and political philosophy that derives from Rawls's and others' work.

Kant’s analysis of the concept of natural purpose in the Critique of judgment captured several features of organisms that he argued warranted making them the objects of a special field of study, in need of a special regulative teleological principle. By showing that organisms have to be conceived as self-organizing wholes, epigenetically built according to the idea of a whole that we must presuppose, Kant accounted for three features of organisms conflated in the biological sciences of the period: adaptation, functionality (...) and conservation of forms..Kant’s unitary concept of natural purpose was subsequently split in two directions: first by Cuvier’s comparative anatomy, that would draw on the idea of adaptative functions as a regulative principle for understanding in reconstituting and classifying organisms; and then by Goethe’s and Geoffroy’s morphology, a science of the general transformations of living forms. However, such general transformations in nature, objects of an alleged ‘archaeology of nature’, were thought impossible by Kant in the §80 of the Critique of judgment. Goethe made this ‘adventure of reason’ possible by changing the sense of ‘explanation’: scientific explanation was shifted from the investigation of the mechanical processes of generation of individual organisms to the unveiling of some ideal transformations of types instantiated by those organisms.

This paper proposes an interpretative framework for some developments of the philosophy of nature after Kant. I emphasize the critique of the economy of nature in the Critique of judgement. I argue that it resulted in a split of a previous structure of knowledge; such a structure articulated natural theology and natural philosophy on the basis of the consideration of the order displayed by living beings, both in their internal organisation and their ecological distribution. The possibility of a philosophical discourse (...) on nature that is neither mathematical nor theological stemmed from this shift. I call “hermeneutics of nature” such a program, since it aims at unpacking an immanent meaning in nature that is not explicated by the sciences of nature, which are dealing with the laws of nature. The Naturphilosophie, undertaken by Schelling, as well as the philosophies of nature of Hegel and Schopenhauer, are several realizations of this program. I highlight the structural traits that they share, such as a pregnant sense of conflicts in nature, an emphasis on the riddles of gender, and above all a prominent status given to organisms as a clue to the meaning of nature. Finally, I try to sketch the ramifications of this hermeneutics of nature in contemporary philosophy, especially phenomenology, and argue that the coming philosophy of nature, as shown by the attempts of syntheses between phenomenology and ecology, seems to depart from this hermeneutical program.

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 (B167), 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)

: Michael Friedman's Kant and the Exact Sciences (1992) refocused scholarly attention on Kant's status as a philosopher of the sciences, especially (but not exclusively) of the broadly Newtonian science of the eighteenth century. The last few years have seen a plethora of articles and monographs concerned with characterizing that status. This recent scholarship illuminates Kant's views on a diverse group of topics: science and its relation to metaphysics; dynamics and the theory of matter; causation and Hume's critique of it; (...) and, the limits of mechanism and of mechanical intelligibility. I argue that recent interpretations of Kant's views on these topics should influence our understanding of his principal metaphysical and epistemological arguments and positions. (shrink)

Gerd Buchdahl's international reputation rests on his masterly writings on Kant. In them he showed how Kant transformed the philosophical problems of his predecessors and he minutely investigated the ways in which Kant related his critical philosophy to the contents and methods of natural science. Less well known, if only because in large part unpublished, are the writings in which Buchdahl elaborated his own views on the methods and status of the sciences. In this paper I examine the roles of (...) hermeneutics in Buchdahl's reconstruction of Kant's philosophical system and in his own 'transcendental methodological' approach to the philosophy of science. The first section looks at Buchdahl's views on the theory and practice of historical interpretation and at the Husserlian hermeneutic scheme of reduction and realisation that he used in his later accounts of the philosophies of science of Kant and himself. The second section concentrates on Buchdahl's treatment of the grounds of science in Kant; and the third on the hermeneutic strategies Buchdahl employed in articulating and justifying his own views. The paper closes with reflections on the impact and importance of Buchdahl's interpretation of Kant's critical philosophy in relation to the sciences and of his own hermeneutically based philosophy of science.

The determination of individual moral status is a central factor in the ethical evaluation of controversial practices such as elective abortion, human embryo-destructive research, and the care of the severely disabled and those in persistent vegetative states. A review of recent work on Kant reveals the need for a careful examination of the content of Kant’s biological and psychological theories and their relation to his views about moral status. Such an examination, in conjunction with Kant’s practical-metaphysical analysis of the origins (...) of freedom, reveals Kant’s principled basis for his contention that all human beings possess moral status.

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

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

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)

Kant's account of Newtonian science in terms of a priori structures of the mind has been generally interpreted as too restrictive. If Newtonian science is an instantiation of the system of categories, then, in order to retain any value, they need to be dynamized in accordance with the development of science beyond Newton. This paper suggests that the restriction in best understood as Kant attempt to provide a primary matrix of sense for any possible natural science, inasmuch as it reflects (...) the "first idea" contained in the Copernican Revolution.
