Kenneth R. Westphal

This book assesses and defends Kant's Critical epistemology, and the rich yet neglected resources it provides for understanding and resolving fundamental issues regarding human experience, perceptual judgment, empirical knowledge and cognitive sciences. Kenneth Westphal first examines Kant's methods and strategies for examining human sensory-perceptual experience, and then examines Kant's central, proper, and subtle attention to judgment, and so to the humanly possible valid use of concepts and principles to judge particulars we confront. This provides a comprehensive account of Kant's anti-Cartesianism, the integrity of his three principles of causal judgment, and Kant's account of disciminatory perceptual-motor behaviour, including both sensory reafference and perceptual affordances. Westphal then defends the significance of Kant's subtle and illuminating account of causal judgment for three main philosophical domains: history and philosophy of science, theory of action and human freedom, and philosophy of mind. Kant's Critical Epistemology will appeal to researchers and advanced students interested in Kant and the relations of his thought to contemporary philosophical debates and to the sciences of the mind.

In this book, Westphal offers an original interpretation of Hegel's moral philosophy. Building on his previous study of the role of natural law in Hume's and Kant's accounts of justice, Westphal argues that Hegel developed and justified a robust form of civic republicanism. Westphal identifies, for the first time, the proper genre to which Hegel's Philosophical Outlines of Justice belongs and to which it so prodigiously contributes, which he calls Natural Law Constructivism, an approach developed by Hume, Rousseau, Kant, and Hegel. He brings to bear Hegel's adoption and augmentation of Kant's Critique of rational judgment and justification in all non-formal domains to his moral philosophy in his Outlines. Westphal argues that Hegel's justification for the standards of political legitimacy successfully integrates Rousseau's Independence Requirement into the role of public reason within a constitutional republic. In these regards, Hegel's moral and political principles are progressive not only in principle, but also in practice. Hegel's Civic Republicanism will be of interest to scholars of moral philosophy, social and political philosophy, philosophy of law, Hegel, eighteenth- and nineteenth-century philosophy.

The scope of this study is both ambitious and modest. One of its ambitions is to reintegrate Hegel's theory of knowledge into main stream epist~ology. Hegel's views were formed in consideration of Classical Skepticism and Modern epistemology, and he frequently presupposes great familiarity with other views and the difficulties they face. Setting Hegel's discussion in the context of both traditional and contemporary epistemology is therefore necessary for correctly interpreting his issues, arguments, and views. Accordingly, this is an issues-oriented study. I analyze Hegel's problematic and method by placing them in the context of Sextus Empiricus, Descartes, Kant, Carnap, and William Alston. I discuss Carnap, rather than a Modern empiricist such as Locke or Hume, for several reasons. One is that Hegel himself refutes a fundamental presupposition of Modern empiricism, the doctrine of "knowledge by acquaintance," in the first chapter of the Phenomenology, a chapter that cannot be reconstructed within the bounds of this study.

I first highlight a main theme of the collection I edited and issued last year, Realism, Science and Pragmatism, by contrasting classical pragmatism and neo-pragmatism in terms of the distinction between semantic externalism and semantic internalism, and exhibiting how both of these semantic views are concisely stated by Carnap, though neither he nor his followers recognised this contrast, nor its profound methodological and substantive implications – although they were highlighted at the time by Wick, published by Wilfrid Sellars and Herbert Feigl in the second year of their journal, Philosophical Studies. I exhibit the continuing influence of semantic internalism – which dominates Quine’s, Rorty’s, van Fraassen’s, Brandom’s and Huw Price’s neo-pragmatist views – and argue against it with pragmatic realist considerations drawn from Kant, Carnap and Sellars.

Kant’s account of cognitive judgment is sophisticated, sound and philosophically far more illuminating than is often appreciated. Key features of Kant’s account of cognitive judgment are widely dispersed amongst various sections of the Critique of Pure Reason, whilst common philosophical proclivities have confounded these interpretive difficulties. This paper characterises Kant’s account of causal-perceptual judgment concisely to highlight one central philosophical achievement: Kant’s finding that, to understand and investigate empirical knowledge we must distinguish between predication as a grammatical form of sentences, statements or judgments, and predication as a cognitive act of ascribing some characteristic to some localised particular. With Kant’s finding in view, I then elucidate how we have occluded his achievement. My results are not merely interpretive, but philosophical, because they show that Kant’s account of perceptual judgment accords with – and indeed justifies – a central and sound point regarding language, thought and reference advocated by apparently unlikely philosophical comrades. These finding highlight some methodological cautions which require re-emphasis today.

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.

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.

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.

The apparent implications of the latest findings of the life sciences for our freedom and autonomy are both exciting and controversial: They undermine a common view of human freedom: a fundamentally Cartesian view. A superior account of our freedom was developed by Kant and Hegel. Key features of Hegel's account show that we can expect from the life sciences further insights into the biological basis of our freedom and autonomy, but not their repudiation. I begin with basic features of Cartesian self-transparency (II) and then review three findings of contemporary life sciences (III). I then detail key features of Hegel's anti-Cartesianism (IV), in order to formulate the basic question about our freedom posed by the claim that biology explains away human freedom (V). I criticize this biological determinism by drawing upon Hegel's account of human freedom as autonomy (VI), and comment briefly on biologism in moral theory (VII).

Does epistemology collapse for lack of resources other than logic, conceptual analysis and descriptions of one’s own apparent experiences, thoughts and beliefs? No, but understanding how and why not requires, Kant noted, a ‘changed method of thinking’. Some of these methodological changes are summarised in §2 in order to identify a philosophical role for thought experiments to help identify logically contingent, though cognitively fundamental capacities and circumstances necessary to human thought, experience and knowledge. As Kant also noted, experiments are only informative in response to posing the right question, indeed: the right kind of question. Accordingly, preparations for these epistemological thought experiments fill half of this chapter. The second half, examines three such thought experiments, variously developed by Kant, Hegel, C. I. Lewis, Austin, Wittgenstein and F. L. Will.
