This landmark book is now reissued in a rewritten & updated edition that takes account of recent Kantian literature. It includes a new discussion of the 'Third Analogy', an expanded discussion of Kant's 'Paralogisms' & new chapters on Kant's theory of reason, theology & the 'Appendix to the Dialectic'.

At the heart of Immanuel Kant's critical philosophy is an epistemological and metaphysical position he calls transcendental idealism; the aim of this book is to understand this position. Despite the centrality of transcendental idealism in Kant's thinking, in over two hundred years since the publication of the first Critique there is still no agreement on how to interpret the position, or even on whether, and in what sense, it is a metaphysical position. Lucy Allais argue that Kant's distinction between things in themselves and things as they appear to us has both epistemological and metaphysical components. He is committed to a genuine idealism about things as they appear to us, but this is not a phenomenalist idealism. He is committed to the claim that there is an aspect of reality that grounds mind-dependent spatio-temporal objects, and which we cannot cognize, but he does not assert the existence of distinct non-spatio-temporal objects. A central part of Allais's reading involves paying detailed attention to Kant's notion of intuition, and its role in cognition. She understands Kantian intuitions as representations that give us acquaintance with the objects of thought. Kant's idealism can be understood as limiting empirical reality to that with which we can have acquaintance. He thinks that this empirical reality is mind-dependent in the sense that it is not experience-transcendent, rather than holding that it exists literally in our minds. Reading intuition in this way enables us to make sense of Kant's central argument for his idealism in the Transcendental Aesthetic, and to see why he takes the complete idealist position to be established there. This shows that reading a central part of his argument in the Transcendental Deduction as epistemological is compatible with a metaphysical, idealist reading of transcendental idealism.

This key collection of essays sheds new light on long-debated controversies surrounding Kant’s doctrine of idealism and is the first book in the English language that is exclusively dedicated to the subject. Well-known Kantians Karl Ameriks and Manfred Baum present their considered views on this most topical aspect of Kant's thought. Several essays by acclaimed Kant scholars broach a vastly neglected problem in discussions of Kant's idealism, namely the relation between his conception of logic and idealism: The standard view that Kant's logic and idealism are wholly separable comes under scrutiny in these essays. A further set of articles addresses multiple facets of the notorious notion of the thing in itself, which continues to hold the attention of Kant scholars. The volume also contains an extensive discussion of the often overlooked chapter in the Critique of Pure Reason on the Transcendental Ideal. Together, the essays provide a whole new outlook on Kantian idealism. No one with a serious interest in Kant's idealism can afford to ignore this important book.

Other works on Kant and on his Critical Philosophy attempt either to remove Kant's transcendental idealism from his system or to defend it as being essential to the Kantian enterprise. In Kant's Idealism, Professor Neujahr argues - he may be the first to do so - that there is no single doctrine that is Kant's transcendental idealism to either explain or explain away. In his Critique of Pure Reason, Kant claims to present a distinctive form of idealism he calls "transcendental" idealism and that he contrasts with the "empirical" idealism of his predecessors. Professor Neujahr argues that on the contrary there is no single form of idealism in Kant's system and no simple contrast between Kant's transcendental idealism and the idealist doctrines of his philosophical forebears. Neujahr finds (and clearly delineates) "strands of idealism" in Kant's philosophy. He argues that the source of these various forms of idealism is the conflicting demands of Kant's theories of perception (sensibility) and thought (understanding). How in fact a subject relates to an object finds no single unified explanation in the Critical Philosophy of Kant. Indeed, in spite of Kant's efforts to combine his various theories into a single theory of experience, his doctrines of perception and thought do not fit together. It is, Neujahr contends, this lack of fit that ultimately prevents there being any single transcendental version of idealism in Kant's system. This also helps explain why Kant's system is so difficult. Neujahr's critical review of that system in Kant's Idealism may be the "handle" needed to get hold of Kant's notoriously difficult but potentially very useful Critical Philosophy.

Kant's discussion of the relations between cognition and self-consciousness lie at the heart of the Critique of Pure Reason , in the celebrated transcendental deduction. Although this section of Kant's masterpiece is widely believed to contain important insights into cognition and self-consciousness, it has long been viewed as unusually obscure. Many philosophers have tried to avoid the transcendental psychology that Kant employed. By contrast, Patricia Kitcher follows Kant's careful delineation of the necessary conditions for knowledge and his intricate argument that knowledge requires self-consciousness. She argues that far from being an exercise in armchair psychology, the thesis that thinkers must be aware of the connections among their mental states offers an astute analysis of the requirements of rational thought.The book opens by situating Kant's theories in the then contemporary debates about 'apperception,' personal identity and the relations between object cognition and self-consciousness. After laying out Kant's argument that the distinctive kind of knowledge that humans have requires a unified self- consciousness, Kitcher considers the implications of his theory for current problems in the philosophy of mind. If Kant is right that rational cognition requires acts of thought that are at least implicitly conscious, then theories of consciousness face a second 'hard problem' beyond the familiar difficulties with the qualities of sensations. How is conscious reasoning to be understood? Kitcher shows that current accounts of the self-ascription of belief have great trouble in explaining the case where subjects know their reasons for the belief. She presents a 'new' Kantian approach to handling this problem. In this way, the book reveals Kant as a thinker of great relevance to contemporary philosophy, one whose allegedly obscure achievements provide solutions to problems that are still with us.

The world, according to Kant, is made up of two levels of reality: the transcendental and the empirical. The transcendental level is a mind-independent level at which things in themselves exist. The empirical level is a fully mind-dependent level at which appearances exist, which are intentional objects of experience. The distinction between appearances and things in themselves lies at the heart of Kant's critical philosophy and has been the focus of fierce debate among scholars for over two hundred years. Anja Jauernig offers this interpretation of Kant's critical idealism as an ontological position, which comprises transcendental idealism, empirical realism, and a number of other basic ontological theses, as developed in the Critique of Pure Reason and associated texts. In this interpretation Kant is a genuine idealist about empirical objects, empirical minds, and space and time. Yet in contrast to other intentional objects, appearances genuinely exist, which is due to both the special character of experience compared to other kinds of representations such as illusions or dreams, and to the grounding of appearances in things themselves. This is why Kant can also be considered a genuine realist about empirical objects, empirical minds, and space and time. This book spells out Kant's case for critical idealism thus understood, pinpoints the differences between critical idealism and ordinary idealism, and clarifies the relation between Kant's conception of things in themselves and the conception of things in themselves by other philosophers, in particular Kant's Leibniz-Wolffian predecessors.

Philosophers working within the pragmatist tradition have pictured their relation to Kant and Kantianism in very diverse terms: some have presented their work as an appropriation and development of Kantian ideas, some have argued that pragmatism is an approach in complete opposition to Kant. This collection investigates the relationship between pragmatism, Kant, and current Kantian approaches to transcendental arguments in a detailed and original way. Chapters highlight pragmatist aspects of Kant’s thought and trace the influence of Kant on the work of pragmatists and neo-pragmatists, engaging with the work of Peirce, James, Lewis, Sellars, Rorty, and Brandom, among others. They also consider to what extent contemporary approaches to transcendental arguments are compatible with a pragmatist standpoint. The book includes contributions from renowned authors working on Kant, pragmatism and contemporary Kantian approaches to philosophy, and provides an authoritative and original perspective on the relationship between pragmatism and Kantianism.

In the Critique of Pure Reason, Kant famously criticizes traditional metaphysics and its proofs of immortality, free will and God's existence. What is often overlooked is that Kant also explains why rational beings must ask metaphysical questions about 'unconditioned' objects such as souls, uncaused causes or God, and why answers to these questions will appear rationally compelling to them. In this book, Marcus Willaschek reconstructs and defends Kant's account of the rational sources of metaphysics. After carefully explaining Kant's conceptions of reason and metaphysics, he offers detailed interpretations of the relevant passages from the Critique of Pure Reason (in particular, the 'Transcendental Dialectic') in which Kant explains why reason seeks 'the unconditioned'. Willaschek offers a novel interpretation of the Transcendental Dialectic, pointing up its 'positive' side, while at the same time it uncovers a highly original account of metaphysical thinking that will be relevant to contemporary philosophical debates.

Presents a reappraisal of Immanuel Kant's conception of and response to skepticism, as set forth principally in the "Critique of Pure Reason". This book argues that Kant undertook his reform of metaphysics primarily in order to render it defensible against these types of skepticism.

This much-needed book examines one of the great lacunae of contemporary philosophical discussion - idealism. Addressing the widespread confusion about the meaning and use of the term, Tom Rockmore surveys and classifies some of its major forms. He argues that Kant provides the essential link between three main types of idealism associated with Plato, the new way of ideas, and German idealism. The author also makes a case for the contemporary relevance of at least one strand in the tangled idealist web, a strand most clearly identified with Kant. In terms of the philosophical tradition, Rockmore contends, constructivism offers a lively, interesting, and important approach to knowledge after the decline of metaphysical realism.
