The advent of distinctively Modern European philosophy at the turn of the seventeenth century was occasioned by two major developments: the painful recognition after thirty years of religious war that principles of public conduct must be justified independently of sectarian religious dogma; and the growth of natural science, especially discoveries in astronomy that linked terrestrial and celestial physics in a newly mathematicized, explanatory mechanics founded by Galileo and dramatically extended by Newton. The roles of reason and empirical evidence in inquiry, and their superiority to custom and tradition for knowledge of nature were undeniable, though their respective roles and proper epistemological accounting were far from obvious. I review briefly some key points in the advent of natural science in order show that some fundamental philosophical predilections have obscured the proper roles of reason and evidence in the philosophical accounting of scientific knowledge. These predilections are found both among rationalists and among empiricists. Though they may be more readily apparent among seventeenth and eighteenth century philosophers, they are no less prevalent in mainstream analytical philosophy of science. Their diagnosis augurs a fundamental philosophical reorientation, a reorientation inaugurated, indeed, by Hegel.

Hegel identified in Kant’s practical philosophy precisely the powerful kind of constructivism about the identification and justification of norms that has recently been explicated by Onora O’Neill. If so (I have argued elsewhere this is so), what then did Hegel contribute to practical philosophy? This essay partly answers this question by examining Kant’s and Hegel’s views of the aim and structure of practical philosophy, and what is required to determine specific duties. This theme is specified by examining these issues: two oversights in Kant’s justification of rights to possession (§2), the role of philosophical anthropology in Kant’s universalization tests (§3), the roles of social institutions in specifying our ethical obligations (§4), Kant’s under-developed view of government (§5), and Hegel’s claim that, in contrast to Kant’s Rechtslehre, his Rechtsphilosophie provides an „immanent“ doctrine of duties (§6). I argue that Hegel attempted to respond to his own criticisms of Kant’s Categorical Imperative, and in doing so, Hegel contributed to practical philosophy in ways that Kantians and other moral, social and legal philosophers should consider seriously.

Hegel’s aesthetic ideal is the perfect integration of form and content within a work of art. This ideal is incompatible with the predominant 20th-century principle of formalist criticism, that form is the sole important factor in a work of art. Although the formalist dichotomy between form and content has been criticized on philosophical grounds, that does not suffice to justify Hegel’s ideal. Justifying Hegel’s ideal requires detailed art criticism that shows how form and content are, and why they should be, integrated in good works of art. This essay provides some of this criticism. By focusing on the work of the contemporary artist, Robert Turner, this criticism further suggests that Hegel’s aesthetic ideal is still relevant. Moreover, the nature of Turner’s work suggests that art is still relevant in our day in ways Hegel did not expect.

: This paper explicates and defends the thesis that individual rational judgment, of the kind required for justification, whether in cognition or in morals, is fundamentally socially and historically conditioned. This puts paid to the traditional distinction, still influential today, between ‘rational’ and ‘historical’ knowledge. The present analysis highlights and defends key themes from Kant’s and Hegel’s accounts of rational judgment and justification, including four fundamental features of the ‘autonomy’ of rational judgment and one key point of Hegel’s account of ‘mutual recognition’. These themes are linked to Kant’s and Hegel’s transformation of the modern natural law tradition. The results explain why Kant’s and Hegel’s philosophy are indeed the origins of the properly pragmatic account of rationality, why the pragmatic account of rationality provides genuine rational justification and why this pragmatic account of rational justification is consistent with realism about the objects of empirical knowledge and with strict objectivity about moral norms. > Russian translation : Nelly Motroshilova, ed., К 200-летию выхода в свет «Феноменологии духа» Гегеля, 195–219. > Turkish translation : ‘Hegel’in Tinin Görüngübilimi’nde Karşihkh Onanma ve Ussal Gerekçelendirme’.

In the Critique of Pure Reason Kant introduced both transcendental idealism and transcendental arguments into philosophy. Transcendental arguments in general aim to establish conditions necessary for our having self-conscious experience at all. Transcendental idealism holds that such conditions do not hold independently of human subjects; those conditions obtain or are satisfied because they are generated or fulfilled by the structure or functioning of the subject’s cognitive capacities. Is transcendental idealism the only possible explanation of such conditions? I pursue this question by exploring a widely neglected issue, the transcendental affinity of the manifold of intuition. I argue the following: (1) This issue remains vital to the second edition of the Critique, even though many passages on the topic were omitted from that edition. (2) Kant’s link between transcendental idealism and transcendental arguments is substantive, not methodological. (3) Kant’s views on transcendental affinity show that there are non-subjective, transcendental material conditions for the possibility of unified self-conscious experience. (4) These conditions and Kant’s arguments for them directly undermine Kant’s own arguments for transcendental idealism. This criticism of Kant’s arguments for transcendental idealism is entirely internal to the first Critique. (5) These points reveal some serious flaws in Henry Allison’s defense of Kant’s idealism. (6) Realists, naturalists, and pragmatists have much to learn and to borrow from Kant’s transcendental analysis of the conditions of unified self-conscious experience.

Henry Harris noted that ‘the Baconian applied science of this world is the solid foundation upon which Hegel’s ladder of spiritual experience rests’. Understanding the philosophical character of Hegel’s Philosophy of Nature requires recognizing some basic legitimate philosophical issues embedded in the development of physics from Galileo to Newton (§2). These issues illuminate the character of Hegel’s analysis of philosophical issues regarding nature (§3) and the central aims and purposes of Hegel’s philosophy of nature (§4). Hegel recognized some key weaknesses in Newton’s own mathematical treatment of planetary orbits which were only rectified when Johann Bernoulli recast Newtonian gravitational theory on the basis of mathematical analysis (calculus). So reconstructed, Newtonian physics provides sufficient grounds to ascribe gravitational force to matter (Enz. §§262, 269). Hegel incorporated this important point into his illuminating accounts of causal laws of nature and natural-scientific explanation. These points reveal how Hegel’s Science of Logic and Philosophy of Nature are interdependent works, integrated in part by Hegel’s critical, moderately holistic theory of semantic meaning and reference. Highlighting these features of Hegel’s Philosophy of Nature illuminates Hegel’s emergentist account of structural and functional organization of various kinds of natural phenomena.

This critical review article on Frederick Neuhouser, The Foundations of Hegel’s Social Theory, examines in detail Hegel’s standards of political legitimacy, according to which social institutions are justified only by their roles in facilitating human freedom in its three basic forms: personal, moral, and social. Social freedom involves both ‘objective’ institutional requirements and ‘subjective’ aspects of personal understanding and endorsement of institutions so far as they fill their requirements. This includes rational, critical assessment of social institutions, and their role in enabling us to achieve our most basic collective good: our complex modern form of freedom.

This critical editorial introduction summarizes and explicates Frederick Will’s pragmatic realism and his account of the nature, assessment, and revision of cognitive and practical norms in connection with: the development of Will’s pragmatic realism, Hume’s problem of induction, the oscillations between foundationalism and coherentism, the nature of philosophical reflection, Kant’s ‘Refutation of Idealism’, the open texture of empirical concepts, the correspondence conception of truth, Putnam’s ‘internal realism’, the redundancy theory of truth, sociology of knowledge, the governance of practice by norms and the assessment and revision of norms in practice, scientific realism, the alleged independence of reason and tradition, rule-following, legal realism, ethical intuitionism and moral relativism, the regress problem (both in epistemology and in moral theory), the paradox of analysis, and culminating in Will’s account of the philosophical governance of norms. These issues are discussed in close consideration of the views of: William Alston, John Dewey, Descartes, Leibniz, Waismann, Austin, Russell, Schlick, Ayer, Richard Rorty, Michael Williams, Hempel, Carnap, Simon Blackburn, Ramsey, Strawson, Kuhn, Wilfrid Sellars, Wittgenstein, Nozick, Dretske, Quine, Barbara Herman, Hardy Jones, Marcus Singer, and Gerd Buchdahl.

Dans laScience de la logiqueet dans l’Encyclopédie des sciences philosophiques,Hegel reconstruit la philosophie critique de Kant en développant i) une logique transcendantale dans laScience de la logiqueet dans laPhilosophie de la nature; ii) une conception pragmatique de l’a priori; et iii) une caractéristique-clé de l’usage du verbe «réaliser» en relation avec les concepts et les principes. Chacun de ces trois éléments constitue un aspect central de la sémantique spécifiquement cognitive de Hegel, que celui-ci développe, en partant de la thèse kantienne de la référence cognitive singulière, en un réalisme pragmatique systématique.

In Kant and the Dynamics of Reason, Gerd Buchdahl proposes to solve Jacobi’s objection to Kant’s metaphysics – one needs a ‘thing-in-itself’ to enter the Critical Philosophy, but one cannot uphold both that philosophy and the ‘thing-in-itself’ – by interpreting Kant in terms of a phenomenological ‘reduction’ of objects to their transcendental conditions and their subesequent ‘realization’ in various theoretical or practical contexts. I summarize Buchdahl’s interpretation and argue: (1) Buchdahl’s view faces an exact analog of Jacobi’s problem; (2) Buchdahl’s view of Kant is much more a reconstruction than an interpretation of the Critical philosophy (this counsels greater caution and frankness about the extent to which we interpret or reconstruct Kant’s texts); (3) Buchdahl’s recent effort to address Kant’s practical philosophy is inadequate.

Hegel’s Philosophy of Right responds to two dichotomies. One is between the freedom of rational thought in its practical application and the givenness of natural impulses and desires. Against Kant Hegel argues that pure reason alone cannot determine the content of any maxim or principle of action. Thus Hegel must find a way in which the content of natural needs and impulses – the only source of content for maxims of action – can be transfigured into contents of rationally self-given principles and maxims. Hegel also responds to the dichotomy between the individual agent and the social whole within which agents act. Hegel argues that this dichotomy is specious because human beings are fundamentally social practitioners and because neither social practices nor individual agents have priority over the other. There are no social practices without social practitioners and there are no social practitioners without social practices. Hegel’s response to this second dichotomy allows him to respond to the first one as well. The elaboration and specialization of natural needs and desires through exchange relations and the social division of labor transfigures the contents of those needs and desires into collectively self-given ends. The social practices producing this transfiguration and meeting these ends form the contents of implicit principles of right. These implicit principles are collectively self-given because they result from the social practices collectively developed to meet these needs. Only acts that are executed and accepted by an agent are free acts. This strong condition requires that an agent’s intentions correspond to the actual nature and consequences of his or her act. Since the aims, the principles, and the means of action are fundamentally social, these strong constraints entail that free action is possible only within a community which makes known its structure and the role of its members within it and their contribution to it, so that its members can act on the basis of that knowledge. Hegel’s theory of the state is a theory of a communal structure that makes such explicit, free action possible. In briefest compass, Hegel holds that laws are legitimate only insofar as they codify those practices that have been developed in order to achieve human freedom, and laws are obligatory only insofar as they are necessary for achieving human freedom. Hegel’s government is designed to codify and promulgate such laws. Hegel’s legislature is designed to make known to the citizens at large, through their corporate representatives, that laws have such a basis and how individual roles and actions fit within the community as a whole.

This paper characterises concisely a key issue about rational justification which highlights an important achievement of Kant’s constructivist method for identifying and justifying basic norms: uniquely, it resolves the Pyrrhonian Dilemma of the Criterion. Kant’s constructivist method is both sound and significant because it is based on core principles of rational justification as such. Explicating this basis of Kant’s constructivism affords an illuminating and defensible explication of four key aspects of the autonomy of rational judgment, including our positive moral freedom; it shows how Kant’s constructivism is fundamentally social and it shows how Kant’s constructivism can readily accommodate historical factors which bear on the appropriateness and legitimacy of social and political institutions. All of these advantages are available without recourse to Kant’s transcendental idealism, and all of them respond to common complaints about or alleged objections to Kant’s practical philosophy.

Rousseau's Du contrat social develops an important, unjustly neglected type of theory, which I call 'Natural Law Constructivism' ('NLC'), which identifies and justifies strictly objective basic moral principles, with no appeal to moral realism or its alternatives, nor to elective agreement, nor to prudentialist reasoning. The Euthyphro Question marks a dilemma in moral theory which highlights relations between artifice and arbitrariness. These relations highlight the significance of Hume's founding insight into NLC, and how NLC addresses Hobbes's insight that our most fundamental moral problems concern social coordination. Part 2 systematically re-examines the core of Rousseau's theory of justice to show that it assigns no constitutive role to contractual agreement in identifying or justifying basic normative principles. Part 3 highlights his NLC

Kant’s and Hegel’s transcendental argument for mental-content externalism breaks the deadlock between ‘internal’ and genuine realists. This argument shows that human beings can only be self-conscious in a world that provides a humanly recognizable regularity and variety among the things (or events) we sense. This feature of the world cannot result from human thought or language. Hence semantic arguments against realism can only be developed if realism about the world is true. Some of Putnam’s arguments for internal realism are taken as cases in point, and criticized accordingly. Pragmatic realists can use this transcendental argument, because its strong modal claims are consistent with falliblist accounts of justification.

Kenneth R. Westphal presents an original interpretation of Hume's and Kant's moral philosophies, the differences between which are prominent in current philosophical accounts. Westphal argues that focussing on these differences, however, occludes a decisive, shared achievement: a distinctive constructivist account of the basic principles of justice which justifies their strict objectivity without invoking moral realism nor moral anti- or irrealism. Westphal explores how Hume developed a kind of constructivism for basic property rights and for government, and how Kant greatly refined Hume's construction of justice within his 'metaphysical principles of justice', whilst preserving the core model of Hume's innovative account. Westphal contends that Hume's and Kant's constructivism avoids the conventionalist and relativist tendencies latent if not explicit in contemporary forms of moral constructivism.

This book provides an important opportunity to explore Hegel's relation to Kant. Hegel claims that a proper criticism of a philosophy must be sufficiently immanent, detailed, and systematic to show that and how a more adequate view is introduced and justified by a thorough comprehension of the merits and deficiencies of another view. However, Hegel's explicit criticisms of Kant cannot be credited with meeting this exacting standard. His lectures on Kant do not get beyond an overview, and though he makes some detailed criticisms in the conceptual preliminaries of the lesser Logic and in a number of remarks in the larger Logic, these criticisms appear isolated. While there is much important criticism of Kant in Hegel's early writings, those criticisms are embedded in Hegel's still embryonic philosophy, and as such do not constitute a thorough and mature Hegelian critique. Furthermore, Hegel scholarship has yet to make up this decisive gap in Hegel's purported proof of his own philosophy; far too little, of far too little detail and scope, has been written on Hegel's critical relation to the critical philosophy.

This chapter considers the centrality of principles in Kant’s moral philosophy, their distinctively ‘Kantian’ character, why Kant presents a ‘metaphysical’ system of moral principles and how these ‘formal’ principles are to be used in practice. These points are central to how Kant thinks pure reason can be practical. These features have often puzzled Anglophone readers, in part due to focusing on Kant’s Groundwork, to the neglect of his later works in moral philosophy, in which the theoretical preliminaries of that first essay are properly articulated. In part, however, these puzzles stem, directly or indirectly, from Kant’s opposition to moral empiricism, which is bound to puzzle Anglophone readers, whose default orientation is empiricist. Accordingly, particular attention is paid to Kant’s reasons for rejecting moral empiricism and for developing an alternative to it, to Kant’s account of how his universalization tests serve as criteria of morally obligatory, permissible or prohibited actions and to his account of what is morally wrong with actions which violate those criteria. Examining these points provides a compelling synopsis of Kant’s system of moral principles, centring on the key terms ‘practical reason’, ‘law’, ‘maxim’ and ‘Categorical Imperative’.

Empirical investigations use empirical methods, data and evidence. This banal observation appears to favour empiricism, especially in philosophy of science, though no rationalist ever denied their importance. Natural sciences often provide what appear to be, and are taken by scientists as, realist, causal explanations of natural phenomena. Empiricism has never been congenial to scientific realism. Bas van Fraassen’s ‘Constructive Empiricism’ purports that realist interpretations of any scientific theory in principle always transcend whatever can be justified by that theory’s empirical adequacy, and that ‘explanations’ are merely pragmatic, insofar as they are context-specific to the presuppositions of whomever poses the question an explanation is to answer. Here I argue that ‘Constructive Empiricism’ rests upon a series of flawed presumptions about natural science and about epistemology. To do so I draw upon two main resources. One resource is the constraints upon specifically cognitive reference to particulars, first identified by Kant (and later by Evans). The second is William Harper’s (2011) brilliant re-analysis and defence of Newton’s Principia, which shows that, and how, Newton justified his realism about gravitational force. One surprise is that Kant’s semantics of singular cognitive reference (examined in §3) directly and strongly supports Newton’s Rule 4 of scientific method (§4), which strongly supports his realism about gravitational force (summarised in §2). A further surprise is that Hegel first recognised that this semantics of singular cognitive reference directly and strongly supports Newton’s methodological Rule 4 of experimental philosophy in ways which support Newton’s realism about gravitational force, and about distance forces generally. The textual and exegetical issues these attributions require I examine elsewhere. Here I make these important findings available to philosophers and historians of science.

Though concise and introductory, this book argues inter alia that Dretske’s information-theoretic epistemology must take into account that many of our information channels are socially constructed, not least through learning concepts and information. These social aspects of human knowledge are consistent with realism about the objects of our empirical knowledge. It further argues that, though important, Margaret Gilbert’s social ontology in principle can neither accommodate nor account for the most fundamental social dimensions of human cognition.

According to Kant, justifying the application of mathematics to objects in natural science requires metaphysically constructing the concept of matter. Kant develops these constructions in the Metaphysical Foundations of Natural Science (MAdN). Kant’s specific aim is to develop a dynamic theory of matter to replace corpuscular theory. In his Preface Kant claims completely to exhaust the metaphysical doctrine of body, but in the General Remark to MAdN ch. 2, “Dynamics,” Kant admits that once matter is reconceived as basic forces, it is no longer possible to construct the concept of matter. I argue that Kant’s admission is only the tip of the problem, and that none of Kant’s commentators has fully grasped the problems infecting the MAdN that underlie Kant’s admission. I show that Kant’s proof that matter consists of forces is fallacious. I then re-analyze the circularity in Kant’s definition of density, criticizing both Adickes’ formulations and his later dissolution of it. I also show that a third circularity infects the relations between Kant’s treatment of “Dynamics” and “Mechanics” (MAdN ch. 3). These three fundamental problems demonstrate the untenability of Kant’s metaphysical method, and they require the radical revision of the relation between mathematics and metaphysics Kant undertakes in his opus postumum. I show that some of Kant’s most surprising and critical later claims about the Critical philosophy are correct, and that they require the sorts of remedies Kant contemplates in the opus postumum. (I defend the essentially correct analyses offered by Burkhard Tuschling and Eckart Forster against criticisms by Michael Friedman.)

The passages translated here show that Hegel espoused ‘moderate collectivism’, a social ontology consisting in three theses: (1) Individuals are fundamentally social practitioners. Everything a person does, says, or thinks is formed in the context of social practices that provide material and conceptual resources, objects of desire, skills, procedures, techniques, and occasions and permissions for action, etc. (2) What individuals do depends on their own response to their social and natural environment. (3) There are no individuals, no social practitioners, without social practices, and vice versa, there are no social practices without social practitioners, without individuals who learn, participate in, perpetuate, and who modify those social practices as needed to meet their changing needs, aims, and circumstances (including information).

Hume and contemporary Humeans contend that moral sentiments form the sole and sufficient basis of moral judgments. This thesis is criticised by appeal to Hume’s theory of justice, which shows that basic principles of justice are required to form and to maintain society, which is indispensable to human life, and that acting according to, or violating, these principles is right, or wrong, regardless of anyone’s sentiments, motives or character. Furthermore, Hume’s theory of justice shows how the principles of justice are artificial without being arbitrary. In this regard, Hume’s theory belongs to the unjustly neglected modern natural law tradition. Some key merits of this strand in Hume’s theory are explicated by linking it to Kant’s constructivist method of identifying and justifying practical principles (à la O’Neill), and by showing how and why Hegel adopted and further developed Kant’s constructivism by re-integrating it with Hume’s central natural law concern with our actual social practices. (Slightly revised English translation by the author of „Von der Konvention zur Sittlichkeit. Humes Begründung einer Rechtsethik aus nach-Kantischer Perspektive“, on which see below.)

By deepening Austin’s reflections on the ‘open texture’ of empirical concepts, Frederick L. Will defends an ‘externalist’ account of mental content: as human beings we could not think, were we not in fact cognizant of a natural world structured by events and objects with identifiable and repeatable similarities and differences. I explicate and defend Will’s insight by developing a parallel critique of Kant’s and Carnap’s rejections of realism, both of whom cannot account properly for the content of experience. This critique shows that Will has identified a genuinely transcendental basis for defending common-sense realism, without appeal to any high-level theory of knowledge. I then show how Will’s realism undercuts Simon Blackburn’s quasi-realism, Michael Williams’ partial defense of skepticism, John Haldane’s attempt to rehabilitate Aquinas’ account of concepts, and how it augments Crispin Wright’s defense of realism.
