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 ...

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. Papers by Karl Ameriks, Manfred Baum, Ido Geiger, Lucy Allais, Gary Banham, Steven M. Bayne, Marcel Quarfood, Dennis Schulting, Dietmar Heidemann, Christian Onof and Jacco Verburgt.

This paper compares Kant's transcendental idealism with three main groups of contemporary anti-realism, associated with Wittgenstein, Putnam, and Dummett, respectively. The kind of anti-realism associated with Wittgenstein has it that there is no deep sense in which our concepts are answerable to reality. Associated with Putnam is the rejection of four main ideas: theoryindependent reality, the idea of a uniquely true theory, a correspondence theory of truth, and bivalence. While there are superficial similarities between both views and Kant's, I find more significant differences. Dummettian anti-realism, too, clearly differs from Kant's position: Kant believes in verification-transcendent reality, and transcendental idealism is not a theory of meaning or truth. However, I argue that part of the Dummettian position is extremely useful for understanding part of Kant's position - his idealism about the appearances of things. I argue that Kant's idealism about appearances can be expressed as the rejection of experiencetranscendent reality with respect to appearances.

Central to any examination of Kant’s Refutation of Idealism—as it appears in the Second Edition of the Critique of Pure Reason—are questions about what sort of “idealism” it is trying to refute and what the precise steps of the supposed refutation might be. The first question is one regarding the nature of the claims made by Kant’s opponent, whilst the second traces the structure of the argument. Once upon a time the concern was that the Refutation turned out to be a voracious refutation of all idealism, including Kant’s own transcendental idealism. That issue has been resolved, however, by the ever more rigorous appreciation of the differences between Kant’s transcendental or formal idealism and the forms of Cartesian and Berkeleian idealism for which the refutation is intended. The Refutation of Idealism, then, is no self-refutation but the soundness of the actual execution of Kant’s argument in the Refutation of Idealism needs to be considered. What I want to demonstrate here is that the argument does not withstand critical scrutiny, precisely as a “refutation of idealism.” I will argue two issues. First, I want show is that as a “refutation of idealism”—considered within and without the broader commitments of transcendental idealism—Kant’s argument fails. This is because it misses a step which leaves the skeptic reasonable space to deny correlation between our representations and outer objects. The step is that of showing that external objects determine the content of our representations. This, I think, is not simply a failing in Kant’s exposition of the Refutation of Idealism but is the culmination of an enormous tension in Kant’s position between his twin commitments to transcendental idealism and empirical realism. This leads to a second important issue: the Refutation of Idealism, I will argue, relies on a notion Page 1 of 21 of “outer objects” that cannot be maintained within the framework of transcendental idealism. I am thereby at odds with Kant’s insistence, within the context of the Refutation at least, that the “transcendental idealist....

This paper gives an interpretation of Kant's argument for transcendental idealism in the Transcendental Aesthetic. I argue against a common way of reading this argument, which sees Kant as arguing that substantive a priori claims about mind-independent reality would be unintelligible because we cannot explain the source of their justification. I argue that Kant's concern with how synthetic a priori propositions are possible is not a concern with the source of their justification, but with how they can have objects. I argue that Kant's notion of intuition needs to be understood as a kind of representation which involves the presence to consciousness of the object it represents, and that this means that a priori intuition cannot present us with a mind-independent feature of reality.

In this article I investigate Kant’s argumentation in the Critique of Pure Reason in favor of transcendental idealism. The argumentation for transcendental idealism seeks to establish the main conjecture of Kant’s Copernican hypothesis, to the effect that objects are conformed to our knowledge and not our knowledge to objects. But if the argumentation for transcendental idealism should presuppose anything of the Copernican hypothesis itself, then such argumentation remains as hypothetical as the Copernican hypothesis. What I seek to establish in this article is that in the Critique Kant presupposes the same presuppositions as does the Copernican turn, in which case transcendental idealism, as defended in the Critique, is nothing more than an elaborate hypothesis.

The debate on how to interpret Kant's transcendental idealism has been prominent for several decades now. In his book Kant's Transcendental Proof of Realism (2004) Kenneth R. Westphal introduces and defends his version of the metaphysical dual-aspect reading. But his real aim lies deeper: to provide a sound transcendental proof for (unqualified) realism, based on Kant's work, without resorting to transcendental idealism. In this sense his aim is similar to that of Peter F. Strawson – although Westphal's approach is far more sophisticated. First he attempts to show that noumenal causation – on the reality of which his argument partly rests – is coherent in and necessary for Kant's transcendental idealism. Westphal then aims to undermine transcendental idealism by two major claims: Kant can neither account for transcendental affinity nor satisfactorily counter Hume's causal scepticism. Finally Westphal defends his alternative for transcendental idealism by showing that it solves these problems and thus offers a genuine transcendental proof for realism. In this paper I will show that all the three steps outlined above suffer from decisive shortcomings, and that consequently, regardless of its merits, Westphal's transcendental argument for realism remains undemonstrated.

In the "Transcendental Aesthetic" of the Critique of Pure Reason, Kant offers an argument for transcendental idealism. This argument is one focus of the longstanding controversy between "one-world" and "two-world" interpretations of the distinction between things in themselves and things as they appear. I present an interpretation of the argument of the "Aesthetic" that supports a novel "one-world" interpretation. On this interpretation, Kant is concerned with the mind-dependence of spatial and temporal properties; and with the idea that space and time can be identified with mental objects. I end by arguing that, for Kant, even on a "one-world" interpretation, we do not know the nature or even the existence of mind-independent things.

This paper takes a fresh look at a classical theme in philosophical scholarship, the meaning of transcendental idealism, by contrasting Kant's and Husserl's versions of it. I present Kant's transcendental idealism as a theory distinguishing between the world as in-itself and as given to the experiencing human being. This reconstruction provides the backdrop for Husserl's transcendental phenomenology as a brand of transcendental idealism expanding on Kant: through the phenomenological reduction Husserl universalizes Kant's transcendental philosophy to an eidetic science of subjectivity. He thereby furnishes a new sense of transcendental philosophy, rephrases the quid iuris-question, and provides a new conception of the thing-in-itself. What needs to be clarified is not exclusively the possibility of a priori cognition but, to start at a much lower level, the validity of objects that give themselves in experience. The thing-in-itself is not an unknowable object, but the idea of the object in all possible appearances experienced at once. In spite of these changes Husserl remains committed to the basic sense of Kant's Copernican Turn. I end with some comments on how both Kant and Husserl view the relation between theoretical and moral philosophy.

This article presents an overview of the current debate on Kant's doctrine of idealism, focussing on the metaphysical interpretations of Ameriks, Allais, Friebe, Langton, Van Cleve and Westphal, and also on Guyer's recent reassessment of Allison's latest views.
