This article examines how Quine and Sellars develop informatively contrasting responses to a fundamental tension in Carnap’s semantics ca. 1950. Quine’s philosophy could well be styled ‘Essays in Radical Empiricism’; his assay of radical empiricism is invaluable for what it reveals about the inherent limits of empiricism. Careful examination shows that Quine’s criticism of Carnap’s semantics in ‘Two Dogmas of Empiricism’ fails, that at its core Quine’s semantics is for two key reasons incoherent and that his hallmark Thesis of Extensionalism is untenable. The tension in Carnap’s semantics together with Quine’s exposure of the severe limits of radical empiricism illuminate central features of Sellars’s philosophy: the fully general form of the myth of givenness, together with Sellars’s alternative Kantian characterisation of understanding; the full significance of Carnap’s distinction between conceptual analysis and conceptual explication, and its important methodological implications; the specifically pragmatic character of Sellars’s realism; and Sellars’s methodological reasons for holding that philosophy must be systematic and that systematic philosophy must be deeply historically and textually informed. This paper thus re-examines this recent episode of philosophical history for its philosophical benefits and systematic insights

Kant was the first great anti-Cartesian in epistemology and philosophy of mind. He criticised five central tenets of Cartesianism and developed sophisticated alternatives to them. His transcendental analysis of the necessary a priori conditions for the very possibility of self-conscious human experience invokes externalism about justification and proves externalism about mental content. Semantic concern with the unity of the proposition—required for propositionally structured awareness and self-awareness—is central to Kant’s account of the unity of any cognitive judgment. The perceptual ‘binding problem’ is central to Kant’s account of the unity of the object in perception. This paper outlines Kant’s development and justification of his a rationalist account of our active intellect and its roles in perceptual consciousness and in rational judgment, including our consciousness of our rational freedom, all through a radically innovative transcendental inquiry into the necessary a priori conditions for us to be conscious at all. Kant’s anti-Cartesianism is a major philosophical breakthrough far surpassing contemporary anti-Cartesian efforts. It behoves us to give Kant his due and avail ourselves of his profound insights into the nature of human mindedness.

Kant’s motto for enlightenment, Sapere aude!, captures important aspects of how the best of Enlightenment thought was radical in the literal sense of probing the roots of fundamental concepts, principles and institutions, in both the natural and in the moral sciences. Here I re-examine a fundamental Enlightenment innovation that has been lost beneath the academic and administrative fray: A sound reconception of how to identify and to justify basic, universally valid moral principles without appeal (whether pro or contra) to moral realism, to ‘motivational sets’ or to our human responsiveness and responses. Kant’s motto for enlightenment thus also holds for our knowledge and understanding of the Enlightenment, and of enlightenment. Kant’s critique of our finite, limited but vitally important powers of rational judgment identifies central aims, methods and skills of liberal education which are increasingly important in our globalizing, yet also destabilizing world, in which these aims, methods and skills go unremarked even by advocates of active learning, of the liberal arts and of their vital roles in today’s rapidly changing world.

This handbook presents the conceptions and principles central to every aspect of Hegel’s systematic philosophy. In twenty-eight thematically linked chapters by leading international experts, The Palgrave Hegel Handbook provides reliable, scholarly overviews of each subject, illuminates the main issues and debates, and details concisely the considered views of each contributor. Recent scholarship challenges traditional, largely anti-Kantian, readings of Hegel, focusing instead on Hegel’s appropriation of Kantian epistemology to reconcile idealism with the rejection of foundationalism, coherentism and skepticism. Focused like Kant on showing how fundamental unities underlie the profusion of apparently independent events, Hegel argued that reality is rationally structured, so that its systematic structure is manifest to our properly informed thought. Accordingly, this handbook re-assesses Hegel’s philosophical aims, methods and achievements, and re-evaluates many aspects of Hegel’s enduring philosophical contributions, ranging from metaphysics, epistemology, and dialectic, to moral and political philosophy and philosophy of history. Each chapter, and The Palgrave Hegel Handbook as a whole, provides an informed, authoritative understanding of each aspect of Hegel’s philosophy.

This book is the first translation into English of the Reflections which Kant wrote whilst formulating his ideas in political philosophy: the preparatory drafts for Theory and Practice, Toward Perpetual Peace, the Doctrine of Right, and Conflict of the Faculties; and the only surviving student transcription of his course on Natural Right. Through these texts one can trace the development of his political thought, from his first exposure to Rousseau in the mid 1760s through to his last musings in the late 1790s after his final system of Right was published. The material covers such topics as the central role of freedom, the social contract, the nature of sovereignty, the means for achieving international peace, property rights in relation to the very possibility of human agency, the general prohibition of rebellion, and Kant's philosophical defense of the French Revolution.

Modern Philosophy bloomed into the Enlightenment, a cultural and philosophical movement still alive today, despite growing criticism. Some recent critics claim (roughly) that the alleged ‘universality’ of Enlightenment reason led directly to the imposition of Eurocentric reason on other, less militarily developed cultures. Some contend that there is no such thing as ‘universal’ reason. I contend that there are serious flaws in the Enlightenment notion of reason resulting from three basic dichotomies: (1) reason versus tradition, (2) knowledge versus customary belief, and (3) individuals versus society. Identifying and remedying these flaws leads, not to the abandonment of rational enlightenment, but to an improved account of human rationality.

Kant’s Critique of Pure Reason contains an original and powerful semantics of singular cognitive reference which has important implications for epistemology and for philosophy of science. Here I argue that Kant’s semantics directly and strongly supports Newton’s Rule 4 of Philosophy in ways which support Newton’s realism about gravitational force. I begin with Newton’s Rule 4 of Philosophy and its role in Newton’s justification of realism about gravitational force (§2). Next I briefly summarize Kant’s semantics of singular cognitive reference (§3), and then show that it is embedded in and strongly supports Newton’s Rule 4, and that it rules out not only Cartesian physics (per Harper) but also Cartesian, infallibilist presumptions about empirical justification generally (§4). This result exposes a key fallacy in Bas van Fraassen’s original argument for his anti-realist Constructive Empiricism (§5).

This book is the first detailed study of Kant's method of 'transcendental reflection' and its use in the Critique of Pure Reason to identify our basic human cognitive capacities, and to justify Kant's transcendental proofs of the necessary a priori conditions for the possibility of self-conscious human experience. Kenneth Westphal, in a closely argued internal critique of Kant's analysis, shows that if we take Kant's project seriously in its own terms, the result is not transcendental idealism but realism regarding physical objects. Westphal attends to neglected topics - Kant's analyses of the transcendental affinity of the sensory manifold, the 'lifelessness of matter', fallibilism, the semantics of cognitive reference, four externalist aspects of Kant's views, and the importance of Kant's Metaphysical Foundations for the Critique of Pure Reason - that illuminate Kant's enterprise in new and valuable ways. His book will appeal to all who are interested in Kant's theoretical philosophy.

The notion that Hegel repudiated epistemology has had dire consequences for our understanding of Hegel. By disregarding epistemology, Hegel’s expositors often disregarded the general issues central to epistemology of how one can establish or justify a philosophical view. If Hegel did address epistemological issues and tried to justify (not simply to expound) ‘absolute knowledge’, then that disregard would produce skewed interpretations of Hegel. Recent attention to Hegel’s epistemology (e.g., by Klaus Hartmann, Joseph Flay, Robert Pippin, Michael Forster, Terry Pinkard, and Justus Hartnack) is salutary. However, I argue that most of these efforts founder by making key assumptions about epistemology that Hegel clearly rejects. Moreover, many of these efforts exhibit hermeneutic defects that Hegel scholars should consider carefully; most of these interpretations are long on interpretive promise but short on philosophical delivery.

In the conceptual preliminaries of his philosophical Encyclopedia Hegel discusses three approaches to epistemology under the headings of three ‘Attitudes of Thought Toward Objectivity’. The third of these is Jacobi’s doctrine of ‘immediate’ or intuitive knowledge. Hegel’s discussion presumes great familiarity with Jacobi’s highly polemical and now seldom read texts. In this essay I disambiguate and reconstruct Hegel’s discussion of Jacobi, in close consideration of Jacobi’s texts, showing why Hegel finds him important and what Hegel’s objections to his doctrines are. Jacobi’s importance for Hegel lies in three points. First, Hegel agrees with Jacobi’s claim, against Kant, that God and the world are themselves knowable. Second, Hegel must answer Jacobi’s charge that discursive thinking ineluctably leads to determinism and ultimately to nihilism. Third, Hegel’s analysis of Jacobi’s doctrine of ‘immediate knowledge’ reveals some points that are important to Hegel’s metaphysics. Hegel mounts five objections to Jacobi’s doctrine. First, Jacobi’s key term ‘immediacy’ illicitly equivocates among the rejection of three different kinds of ‘mediation’: syllogistic inference, the application of concepts, and representational accounts of perception. Second, Jacobi’s doctrine of a-conceptual knowledge is untenable because one must apply concepts to objects in order identify objects and thus to know what kinds of things known objects are. Third, if a fundamental point of Hegel’s holistic ontology (explained in the essay) is correct, then the identity conditions of things are interdependent, and this interdependence would render ‘immediate’ knowledge impossible. Fourth, Jacobi’s doctrine is self-referentially inconsistent: it is possible on his doctrine to prove that his doctrine is false. Finally, Jacobi’s doctrine licenses question-begging and is in principle unable to address or to settle disagreements among divergent intuitions.

Gauthier’s contractarianism begins with an idea of a rational deliberator but ‘finds no basis for postulating a moral need for the justification of one’s actions to others. The role of agreement is to address each person’s demand that the constraints of society be justified to him, not a concern that he justify himself to his fellows’ (Gauther 1997, 134–5). He contrasts his view with Scanlon’s contractualism, according to which agreement with others is the core of morality and each agent has the burden of justifying his or her actions to others. Both of their views count as ‘constructivist’ because they reject moral realism and hold that normativity is a function of what we do, either individually or collectively. Kant’s Rechtslehre is neutral regarding moral realism and yet constructivist about moral norms. However, the relevant acts basic to Gauthier’s and Scanlon’s views concern voluntary agreements we make. Using agreement to establish basic norms faces some serious difficulties. Kant’s Rechtslehre avoids these problems by showing how basic social norms can be identified and justified independently of voluntary agreement. Moreover, it does so in a way that shows that an individual’s justification of his or her acts to others and the justification of the acts of others to any individual are inseparable aspects of one and the same justificatory reasons in which voluntary agreement plays no role.

This paper extends my prior analysis of Hegel’s solution to the Pyrrhonian Dilemma of the Criterion to moral philosophy. So doing provides a uniform account of rational justification in non-formal, substantive domains, i.e. empirical knowledge and morals. It argues that the Pyrrhonian Dilemma refutes both foundationalist and coherentist models of justification, and raises serious issues about the justificatory adequacy of contemporary forms of moral constructivism. It explicates and defends Kant’s account of the autonomy of reason as the self-critical regulation of one’s own thought and judgment in view of relevant principles, standards, evidence and alternative analyses. It argues that Kant’s account of autonomy is defensible independently of transcendental idealism and of natural causality. Due to our fallibility and incomplete knowledge and understanding, our individual critical self-assessment requires the constructive mutual criticism of others. Hence maximally rational justification in non-formal, substantive domains is in part, ineliminably, a social and historical phenomenon. These aspects of rational justification are consistent with, and ultimately support, realism about the objects of empirical knowledge and strict objectivity about basic moral principles. One’s own maximally rational justification of non-formal, substantive claims or views accordingly requires recognition of one’s justificatory dependence upon the constructive criticism of others. This requires recognizing their capacities for critical assessment and rational justification. This is the most fundamental form of mutual recognition in Hegel’s analysis. It provides direct and powerful justification for Kant’s thesis that we ought and must respect all others as autonomous rational agents, as agents who can think and act on the basis of justifying reasons. This justification is independent of Kant’s account of ‘dignity’ or the incommensurable value of rational agency.

In 1801 Hegel charged that, on Kant’s analysis, forces are ‘either purely ideal, in which case they are not forces, or else they are transcendent’. I argue that this objection, which Hegel did not spell out, reveals an important and fundamental line of internal criticism of Kant’s Critical philosophy. I show that Kant’s basic forces of attraction and repulsion, which constitute matter, are merely ideal because Kant’s arguments for them are circular and beg the question, and they have no determinate connection to any of the basic forces of Newtonian physics. Hence they are mere Gedankendinge. I argue further, that real physical forces transcend Kant’s analysis by showing that his proof of Newton’s law of inertia is unsound. I then show that this apparently specific disagreement underlies the enormous philosophical shift from Kant’s anti-naturalist transcendental idealism to Hegel’s naturalistic use of regressive, quasi-transcendental arguments.

If Hegel’s 1807 Phenomenology is to justify our capacity to know the world as it is, by examining a complete series of forms of consciousness, why and with what justification does he omit the Cartesian ego-centric predicament? By augmenting Franco Chiereghin’s explication of Hegel’s concept of thought, and of why Hegel provides it only at the start of the second half of ‘Self-Consciousness’, this paper shows how Hegel showed that Pyrrhonian, Cartesian and Humean scepticism, and also mental content internalism, all depend upon the deductivist model of rational justification (scientia), and that this model is suited only to strictly formal domains, not to the non-formal substantive domain of empirical knowledge. Hegel thus refutes the epistemological presuppositions of the ego-centric predicament; hence he may omit it from the forms of consciousness examined in the Phenomenology.

Through a careful examination of two detailed investigations of Kant’s Categorical Imperative as a criterion for determining correct action I show that Hegel’s widely castigated critique of Kant’s CI has significant merit. Kant holds that moral imperatives are categorical because the obligations they express do not depend upon our contingent ends or desires and he holds that the CI is the supreme normative principle. However, his actual illustrations show that Kant repeatedly appeals to contingent ends and desires in deriving our obligations and that CI tests often reveal conflicts between maxims and other presupposed norms of action. Moreover, Barbara Herman makes a persuasive case that Kant’s CI test must be supplemented by ‘Rules of Moral Salience’ and by ‘Middle Theory’, which links Kant’s theory of value to a theory of applications. These supplements ultimately shift the principle of universalization from the standpoint of individual morality to social ethics – precisely Hegel’s strategy in his Philosophy of Right!

Kant’s justification of possession appears to beg the question (petitio principii) by assuming rather than proving the legitimacy of possession. The apparent question-begging in Kant’s argument has been recapitulated or exacerbated but not resolved in the secondary literature. A detailed terminological, textual, and logical analysis of Kant’s argument reveals that he provides a sound justification of limited rights to possess and use things (qualified choses in possession), not of private property rights. Kant’s argument is not purely a priori; it is in Kant’s Critical sense ‘metaphysical’ because it applies the pure a priori ‘Universal Principles of Right’ to the concept of finite rational human agency. The application of this principle implicitly involves a ‘Contradiction in Conception’ test. I explicate this test in detail and show, inter alia, how Kant’s argument relates to the modern natural law tradition. I further argue that Kant’s ‘Universal Principle of Right’ is justified by appeal to a fundamental principle of justification, the Principle of Mutual Acceptability. This justification also suggests that the debate between Kantians and Utilitarians about whether human ‘dignity’ is an incommensurable value is moot because Kant’s test of the Categorical Imperative need not appeal to ‘dignity’. Finally, I show that the limited rights to possession and use justified by Kant’s argument suffice for his social contract argument for the legitimacy of the state.

Rejection of the philosophical relevance of history of philosophy remains pronounced within contemporary analytic philosophy. The two main reasons for this rejection presuppose that strict deduction is both necessary and sufficient for rational justification. However, this justificatory ideal of scientia holds only within strictly formal domains. This is confirmed by a neglected non-sequitur in van Fraassen’s original defence of ‘Constructive Empiricism’. Conversely, strict deduction is insufficient for rational justification in non-formal, substantive domains of inquiry. In non-formal, substantive domains, rational justification is also, in part, ineliminably social and historical, for sound reasons Hegel was the first to articulate. Demonstrating this involves considering closely two key reasons many analytic philosophers (still) reject the philosophical relevance of historical philosophy (§2). As specific example of presumed, though fallacious, deductivism about justification in the non-formal domain of empirical knowledge is found in van Fraassen’s (1980) defence of ‘Constructive Empiricism’ (§3). These first two sections contend that philosophical consideration of historical philosophy is required to properly formulate key issues in non-formal domains. I next consider the further issues involved rational justification in non-formal domains, issues quintessentially posed by the Pyrrhonian Dilemma of the Criterion (§4). Finally I consider what kind of history of philosophy is required for cogent philosophy in non-formal domains (§5).

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.

: 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’.

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.

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.
