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.

I will discuss Kant's arguments in these section in three parts. In Part I, I will try to show how we can make sense of the obviously close relations in theme and content between the Refutation of Idealism and the two version of the Fourth Paralogism, as well as the second Postulate of Empirical Thought. This will serve as a kind of introduction, since on a cursory first reading, the connections might be far from apparent. In the process, I will try to isolate a few basic..

In what follows I will address Kant’s concerns in the First Analogy and in the Refutation of Idealism. Because the two discussions have a similar trajectory, it is of interest to identify some of the differences between them. As we will see, the manifest differences are indicative of more significant underlying differences, regarding two ways of construing transcendental proofs.

This paper assesses the role of the Refutation of Idealism within the Critique of Pure Reason, as well as its relation to the treatment of idealism in the First Edition and to transcendental idealism more generally. It is argued that the Refutation is consistent with the Fourth Paralogism and that it can be considered as an extension of the Transcendental Deduction. While the Deduction, considered on its own, constitutes a 'regressive argument', the Refutation allows us to turn the Transcendental Analytic into a 'progressive argument' that proceeds by the synthetic method.

While there is good reason to think that Mendelssohn's Morgenstunden targets some of the key claims of Kant’s first Critique, this criticism has yet to be considered in the appropriate context or presented in all of its systematic detail. I show that far from being an isolated assault, Mendelssohn’s attack in the Morgenstunden is a continuation and development of his earlier criticism of Kant’s idealism as presented in the Inaugural Dissertation. I also show that Mendelssohn’s objection was more influential on Kant than has previously been suspected; not only did Kant respond to it in a brief review and a set of remarks published along with a disciple’s examination of Mendelssohn’s text but, as I will suggest, Kant’s Refutation of Idealism is intended (at least in part) to undermine the Cartesian starting-point Mendelssohn had presumed throughout his campaign against Kantian idealism.

I reply to the most important criticisms made by Chignell of my ‘Kant's Refutation of Idealism’. I also introduce a new consideration which brings out more fully the power of Kant's argument.

Building on the research of Manfred Kuehn, the author argues that, whatever influence the Scottish Common Sense Philosophy of Thomas Reid may have had on the development of Immanuel Kant’s refutation of idealism, it was filtered through the thinking of Kant’s largely forgotten German contemporary, Johann Nicolaus Tetens. While the importance of Tetens for understanding Kant is examined in connection with only one idea, the aim is to demonstrate that Tetens is a figure worthy of serious historical consideration.

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....
