The Location of Kant's Refutation of Idealism

Many philosophers have been puzzled by Kant's decision to insert the Refutation of Idealism into the second edition of the first Critique at the end of his elucidation of the Second Postulate. This article proposes a solution to the puzzle. It defends an explanation for the location of Kant's Refutation of Idealism that is plausibly expressed by Kant's claim at the end of his elucidation of the Second Postulate that the Refutation of Idealism is ‘here in its right place’ because ‘[a] powerful objection against these rules for proving existence indirectly is made by idealism’ (B274). According to this explanation, the Refutation of Idealism is Kant's response to the objection that the Second Postulate must be false since otherwise idealism is true. This article also considers and rejects a number of alternative explanations for the location of Kant's Refutation of Idealism.     

Absolute Time: The Limit of Kant's Idealism

I examine here if Kant can explain our knowledge of duration by showing that time has metric structure. To do so, I spell out two possible solutions: time's metric could be intrinsic or extrinsic. I argue that Kant's resources are too weak to secure any intrinsic, transcendentally‐based temporal metrics; but he can supply an extrinsic metric, based in a metaphysical fact about matter. I conclude that Transcendental Idealism is incomplete: it cannot account for the durative aspects of experience—or it can do so only with help from a non‐trivial metaphysics of material substance.     

To Have and to Hold: Intelligible Possession and Kant's Idealism

While the debate about whether Kant's idealism requires a ‘Two Worlds’ or ‘Two Aspect’ interpretation has reached a seeming impasse, I argue that the account of intelligible possession found in the ‘Doctrine of Right’ provides novel and compelling evidence in favour of an epistemic ‘Two Aspect’ reading of Kant's position.     

IV—Kant's Argument for Transcendental Idealism in the Transcendental Aesthetic

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.     

Refutation by Parallel Argument

This paper discusses the method when an argument is refuted by a parallel argument since the flaw of the parallel argument is clearly displayed. The method is explicated, examined and compared with two other general methods.

Idealism and illusions

According to the idealist, facts about phenomenal experience determine facts about the physical world. Any such view must account for illusions: cases where there is a discrepancy between the physical world and our experiences of it. In this article, I critique some recent idealist treatments of illusions before presenting my own preferred account. I then argue that, initial impressions notwithstanding, it is actually the realist who has difficulties properly accounting for illusions.     

McDowell and Idealism

John McDowell espouses a certain conception of the thinking subject: as an embodied, living, finite being, with a capacity for experience that can take in the world, and stand in relations of warrant to subjects' beliefs. McDowell presents this conception of the subject as requiring a related conception of the world: as not located outside the conceptual sphere. In this latter conception, idealism and common‐sense realism are supposed to coincide. But I suggest that McDowell's conception of the subject scuppers this intended coincidence. The upshot is a dilemma: McDowell can retain his conception of the subject, but lose the coincidence; or he can keep the coincidence, but abandon his conception of the subject.     

Nominalism and Idealism

The article considers, in a historical setting, the links between varieties of nominalism—the extreme nominalism of the Quine-Goodman variety and the trope nominalism current today—and types of idealism. In so doing arguments of various twentieth century figures, including Husserl, Bradley, Russell, and Sartre, as well as a contemporary attack on relations by Peter Simons are critically examined. The paper seeks to link the rejection of realism about universals with the rejection of a mind-independent “world”—in short, linking nominalism with idealism.     

A Refutation of Skeptical Theism

Skeptical theists argue that no seemingly unjustified evil (SUE) could ever lower the probability of God's existence at all. Why? Because God might have justifying reasons for allowing such evils (JuffREs) that are undetectable. However, skeptical theists are unclear regarding whether or not God's existence is relevant to the existence of JuffREs, and whether or not God's existence is relevant to their detectability. But I will argue that, no matter how the skeptical theist answers these questions, it is undeniable that the skeptical theist is wrong; SUEs lower the probability of God's existence. To establish this, I will consider the four scenarios regarding the relevance of God's existence to the existence and detectability of JuffREs, and show that in each—after we establish our initial probabilities, and then update them given the evidence of a SUE—the probability of God's existence drops.
