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).

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.

This paper explicates and argues for the thesis that individual rational judgment, of the kind required for rational justification in non-formal, substantive domains – i.e. in empirical knowledge or in morals (both ethics and justice) – is in fundamental part socially and historically based, although these social and historical aspects of rational justification are consistent with realism about the objects of empirical knowledge and with strict objectivity about basic moral principles. The central thesis is that, to judge fully rationally that one judges – in ways which provide rational justification of one’s judgment about any substantive matter – requires recognising one’s inherent fallibility and consequently also recognising our mutual interdependence for assessing our own and each others’ judgments and their justification. This explication provides a pragmatic account of rational justification in substantive domains which puts paid to the traditional distinction, still influential today, between ‘rational’ and ‘historical’ knowledge. (Note: This paper is a counterpart to Westphal 2011b; each paper contains substantial material not included in the other.)

In Hegel’s Idealism, Robert Pippin contends that Hegel develops a more adequate version of Fichte’s idealism, where the key to idealism lies in the general thesis that there are conditions presupposed by self-conscious judgments about objects. Focusing on this thesis led post-Kantian German idealists to dismiss Kant’s doctrine that space and time are a priori forms of intuition and to develop views of the autonomy of human reason in terms of thought’s self-determination. While Pippin and I agree on some fundamentals, we disagree diametrically about the nature of Hegel’s idealism. Four of my main objections are these. (1) The thesis that there are conditions for self-conscious judgments about objects only entails idealism given certain kinds of conditions (such as Kant’s doctrines about space and time). (2) Hegel expressly denies that ‘the autonomy of thought’ primarily concerns the autonomy of human thinking. (3) Pippin’s interpretation of Hegel’s chapter on ‘Force and Understanding’, which is decisive for his interpretation of Hegel’s idealism, is not borne out by the examples Hegel uses to illustrate and defend his view. (4) Hegel’s frequent use in his Logics of categories that plainly derive from contingent features of our world is not, as Pippin would have it, an ironic concession that marks the reductio ad absurdum of Hegel’s view. On the contrary, such categories and their empirical basis is central to Hegel’s idealism, which is deeply naturalistic and expressly based in the empirical sciences.

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

Hume sought to analyse our propositionally-structured thought in terms of our ultimate awareness of nothing but objects, sensory impressions or their imagistic copies, The ideas of space and time are often regarded as exceptions to his Copy Theory of impressions and ideas. On grounds strictly internal to Humes account of the generality of thought. This ultimately reveals the limits of the Copy Theory and of Concept Empiricism. The key is to recognise how very capacious is our (Humean) imaginative capacity to associate particular perceptions by various fine-grained determinable resemblances

Hegel holds that members of a society can only be fully free and autonomous if they enjoy political representation. Hegel grants political representation to the landed aristocracy and to members of corporations. Causal day laborers fall outside both of these groups. Consequently, they lack political representation in Hegel’s state; hence they lack the political resources for full freedom and autonomy. This is a serious problem, but not so serious as Hegel’s marxist critics maintain. I propose two solutions based on Hegel’s institutional principles. First, day laborers typically work in the same industry, and often in the same factory. Once that regularity is established, such labor is no longer casual and it merits recognition through labor contracts and (ultimately) through corporate membership. Second, those workers who remain casual laborers deserve special attention from a government-sponsored agency which organizes and regularizes their training and job placement, and which represents their interests in Hegel’s Estates Assembly. I further suggest that Keynes’s public works strategy for moderating unemployment fits perfectly into Hegel’s institutional framework, and I show (contra Ilting) that Hegel’s exposition of the Crown is properly ordered. The Monarch is the organizational apex of Hegel’s government, but the Estates Assembly culminates Hegel’s program for achieving the political autonomy of individuals.

This paper argues that the problem of the apparent conflict between freedom of action and natural causal determinism has not been properly framed, because the key premiss—the thesis of universal causal determinism—is, in the domain of human behaviour, an unjustified conjecture based on over-simplified, under-informed explanatory models. Kant's semantics of singular cognitive reference, which stands independently of his Transcendental Idealism, justifies and emphasises a quadruple distinction between causal description, causal ascription, true causal ascription and cognitively justified causal ascription. Contemporary causal theories of mind, of action or of meaning do not suffice for causal ascription, and so cannot suffice for causal predication, and hence cannot justify causal determinism about human behaviour. More generally, the principle of universal causal determinism is a regulative principle governing causal inquiry and was so formulated by LaPlace. Only successful, sufficient causal explanation of particular events provides for causal knowledge of those events. Such knowledge we lack in the domain of human behaviour. Rational belief, including scientific belief, requires apportioning belief to justifying evidence; all else is conjecture or speculation, which do not justify premises of sound proofs. Causal determinism about human behaviour remains unjustified speculation, for sound Critical reasons Kant provided us in the Kritik der reinen Vernunft. In these regards, contemporary debates about these issues remain decidedly pre-Critical.

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.

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.

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.

I argue that Hegel is aware of a crucial problem in Kant’s transcendental account of the conditions of human knowledge. Unless the matter of sensation is sufficiently ordered (and sufficiently varied) we could not make any cognitive judgments. In that case we could not distinguish ourselves from objects we know, and so could not be self-conscious. This is a necessary, formal and transcendental condition of possible human experience. However, it is also (as Kant acknowledged) a material – not a conceptual or an intutive – condition. Consequently, Kant’s idealism cannot account for it. This provides one key to Hegel’s internal critique of Kant’s idealism.

This paper examines Hegel’s ontological revolution in ‘Force and Understanding’. I argue that understanding Hegel’s critical engagement with natural science is important for understanding Hegel’s 1807 Phenomenology of Spirit as well as his mature philosophy as a whole. Already in this chapter Hegel argues that philosophical theory of knowledge must take the natural sciences into close consideration. Hegel disambiguates the standard concept of substance in order to show that relational properties can be essential to particular individuals. He further argues that Newtonian gravitational theory suffices to show that gravitational force is essential to matter. These are important tenets of Hegel’s moderately holistic ontology, according to which individuals and their relations are mutually interdependent for their existence and characteristics. These tenets enable Hegel to expose a number of misconceptions about causal forces central to empiricist causal scepticism, to illuminate the causal realism involved in and justified by Newtonian gravitational theory (once it is recast by Bernoulli on the basis of mathematical analysis), the explanatory power provided by theoretical integration of special theories within more general theories and also the crucial semantic role played by special theories for the general theory which subsumes them.

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).

According to Kant’s Metaphysical Foundations of Natural Science, a proper science is organized according to rational principles and has a pure a priori rational part, its metaphysical foundation. In the second edition Preface to the first Critique, Kant claims that his account of time explains the a priori possibility of Newton’s laws of motion. I argue that Kant’s proof of the law of inertia fails, and that this casts doubt on Kant’s enterprise of providing a priori foundations for Newton’s physics.

This paper argues that Hegel’s Philosophical Outlines of Justice develops an incisive natural law theory by providing a comprehensive moral theory of a modern republic. Hegel’s Outlines adopt and augment a neglected species of moral constructivism which is altogether neutral about moral realism, moral motivation, and whether reasons for action are linked ‘internally’ or ‘externally’ to motives. Hegel shows that, even if basic moral norms and institutions are our artefacts, they are strictly objectively valid because for our very finite form of semi-rational embodied agency they are necessary and because sufficient justifying grounds for these norms and institutions can be addressed to all persons. Hegel’s moral constructivism identifies and justifies the core content of a natural law theory, without invoking metaphysical issues of moral realism, anti-realism, irrealism or ‘truth makers’, etc. I begin with Socrates’ question to Euthyphro to distinguish between moral realism and moral irrealism. I then summarise basic points of constructivist method and how Hume’s theory of justice inaugurates this distinctive species of natural law constructivism. How this approach addresses issues of political legitimacy is highlighted by Rousseau’s juridical innovation. How this approach is better articulated and justified by Kant’s specifically Critical method is briefly considered in connection with his justification of rights to possession, so that we can then recognise Hegel’s natural law constructivism in his Outlines. Hegel’s account of rights to possession corresponds closely to Kant’s, and his account of juridical relations as human interrelations accords with natural law constructivism. This finding is corroborated by some central features of Hegel’s account of Sittlichkeit, including how Hegel adopts, undergirds and augments Rousseau’s and Kant’s Independence Requirement for political legitimacy.

Peirce's study of Kant, and later of Hegel, and Dewey's (1930) retention of much of Hegel's social philosophy are recognised idealist sources of pragmatism. Here I argue that the transition from idealism to pragmatic realism was already achieved by Hegel. Hegel's ‘Objective Logic’ corresponds in part to Kant's ‘Transcendental Logic’ (WdL,GW21:47.1-3). Hegel faults Kant for relegating concepts of reflection to an Appendix to his Transcendental Logic (WdL,GW12:19.34-38), and for treating reason as ‘only dialectical’ and as ‘merely regulative’ (WdL,GW12:23.12,.16-17). I present three important yet neglected features of Kant'sCritique of Pure Reasonwhich are key enthymemes undergirding Hegel's critical reconstruction of Kant's Critical philosophy (§2). I then summarise some features of the philosophical context within which Hegel begins to re-assess and reconstruct Kant's Transcendental Logic (§3), and review several key steps in this direction Hegel undertook in the 1807Phenomenology(§4). (A related paper extends these results to Hegel'sLogicandEncyclopaedia.) These points show that Hegel's reanalysis of Kant's Critical philosophy is the first and still one of the most sophisticated and adequate pragmatic — specifically pragmatic realist — accounts of thea priori.

Hegel has been widely, though erroneously, supposed to have rejected epistemology in favor of unbridled metaphysical speculation. Reputation notwithstanding, Hegel was a very sophisticated epistemologist, whose views have gone unrecognized because they are so innovative, indeed prescient. Hence I shall boldly state: Hegel's epistemology is of great contemporary importance. In part, this is because many problems now current in epistemology are problems Hegel addressed. In part, this is because of the unexpected effectiveness of Russell's 1922 exhortation, “I should take ‘back to the 18th century’ as a battle-cry, if I could entertain any hope that others would rally to it.” I shall elaborate on these thematic connections between Hegel's views and our problems below (§3), after summarizing the main features of Hegel's epistemology (§2). Thereafter I consider Hegel's views in relation to 20th-century empiricism (§4), Dretske's information theory (§5), and the on-going debate between realists and historicist relativists (§6). Sections 2–4 will be summary in character, for I have discussed these issues in detail elsewhere. Sections 5 and 6 shall consider more closely some important social aspects of Hegel's epistemology. Two themes of my remarks are that Hegel anticipated by 150 years the recent rejections in epistemology of concept-empiricism and of individualism, and more importantly, Hegel showed how rejecting these positions does not require rejecting commonsense realism about the objects of empirical knowledge. In part, this is because Hegel rejected “internalism” about mental content. The recent wave of anti-Cartesianism in epistemology and philosophy of mind has much to learn from Hegel. Benefiting from Hegel' insights and analyses, however, requires understanding just what were Hegel's aims, methods, and arguments in epistemology. These, however, have eluded most commentators, whether critical or sympathetic. So I begin by reviewing the main points of Hegel's epistemology.
