Transcendental arguments offer a particularlypowerful strategy for combating skepticism. Such arguments, after all, attempt to show thata particular skepticism is not simply mistakenbut inconsistent or self-refuting. Whilethus tempting to philosophers struggling withskepticism of various sorts, the boldconclusions of these arguments have longrendered them suspicious in the eyes of many. In fact, in a famous paper from 1968 BarryStroud develops what is often taken to be adecisive case against transcendental argumentsin general.Recent work in the area of practical reason,however, suggests that such arguments stillhave their defenders. Theorists such as JamesDreier and Christine Korsgaard have reliedexplicitly on transcendental arguments tojustify certain principles of practical reason. Can such arguments overcome Stroud's objection? In what follows, I argue that they can. However effective Stroud's general criticismmay be in other areas, it does not apply in therealm of practical reason. Nevertheless, thereare strict limits on how far transcendentalarguments can take us. In particular, despiteKorsgaard's efforts, they cannot succeed inestablishing a rational foundation formorality.

I consider two transcendental arguments for realism in the philosophy of science, which are due to Roy Bhaskar (A realist theory of science, 1975) and Nancy Cartwright (The dappled world, 1999). Bhaskar and Cartwright are both influential figures, however there is little discussion of their use of transcendental arguments in the literature. Here I seek to correct this oversight. I begin by describing the role of the transcendental arguments in question, in the context of the broader philosophical theories in which they are embedded, by Bhaskar and Cartwright respectively. I then consider some specific problems that arise for these particular transcendental arguments, in the context of contemporary philosophy of science. I raise two general problems for transcendental arguments for realism and I finish by spelling out what needs to be done to address the criticisms raised in this paper.

This essay considers attempts to refute scepticism by transcendental argumentation; in particular I explore attempts to refute traditional "Cartesian" scepticism with idealistic transcendental arguments. My main conclusions are: Transcendental arguments are indispensable for a refutation of scepticism, not redundant; Idealistic transcendental arguments cannot refute Cartesian sceptical doubts; Traditional sceptical doubts can be reformulated so as to be effective against accounts of knowledge based on an idealistic theory of truth; It is possible in principle that idealistic ("Kantian") transcendental arguments can refute such idealistic sceptical doubts and also that non-idealistic ("Strawsonian") transcendental arguments can refute non-idealistic doubts; Merely to assume a theory of truth and just to dismiss certain sceptical doubts based on another theory of truth is to beg the question against the sceptic; but all arguments for a particular theory of truth beg the question against radical sceptics; Because radical scepticism must be taken seriously, a complete refutation of scepticism would require constructing both types of transcendental arguments, viz. Kantian idealistic arguments (to refute idealistic doubts) and Strawsonian non-idealistic arguments (to refute non-idealistic, "Cartesian" doubts). I argue that the allure of idealism as a way to refute scepticism is wholly unfounded, viz. because (1) sceptical doubts can be reformulated so as to be effective against idealistic conceptions of knowledge and (2) idealistic arguments cannot refute traditional Cartesian doubts. But although it doesn't lead where many have hoped, I argue that--in a strange way, for different reasons than are commonly supposed--idealism represents a road which must nevertheless be taken if scepticism is to be refuted. That is, though most of the essay attempts to establish that refuting Cartesian scepticism requires that they be separated, it also follows from my argument that transcendental arguments and transcendental idealism must not be kept apart if scepticism is to be fully refuted..

The paper aims to cast light on the kind of proof involved in central transcendental arguments. It is suggested that some of the difficulty associated with such arguments may result from the tendency to construe them simply as articulating relations between concepts or propositional contents. A different construal, connected with phenomenological description, is outlined, as a way of bringing out the force of these arguments. It is suggested that it can be fruitful to think in terms of this construal in understanding some of Kant's transcendental proofs. The recommended construal also helps to understand the nature of the link between transcendental arguments and transcendental idealism.

‘Performative’ transcendental arguments exploit the status of a subcategory of self-falsifying propositions in showing that some form of skepticism is unsustainable. The aim of this paper is to examine the relationship between performatively inconsistent propositions and transcendental arguments, and then to compare performative transcendental arguments to modest transcendental arguments that seek only to establish the indispensability of some belief or conceptual framework. Reconceptualizing transcendental arguments as performative helps focus the intended dilemma for the skeptic: performative transcendental arguments directly confront the skeptic with the choice of abandoning either skepticism or some other deep theoretical commitment. Many philosophers, from Aristotle and St. Thomas Aquinas to Jaakko Hintikka, C.I. Lewis, and Bernard Lonergan, have claimed that some skeptical propositions regarding knowledge, reason, and/or morality can be shown to be self-defeating; that is to say, they have claimed that the very upholding of some skeptical position is in some way incompatible with the position being upheld, or with the implied, broader dialectical position of the skeptic in question. Statements or propositions alleged to have this characteristic also sometimes are called ‘self-falsifying,’ ‘self-refuting,’ ‘self-stultifying,’ ‘self-destructive,’ or ‘pointless.’ However, proponents of the strategy of showing skepticism to be self-defeating have not in general adequately distinguished between two types of self-defeating proposition: self-falsifying and self-stultifying. In the first part of this paper I distinguish between self-falsifying and self-stultifying propositions, and introduce the notion of performative self-falsification. In the second part I discuss classical transcendental arguments, ‘modest’ transcendental arguments, and objections to each. In the third part I introduce two types of transcendental argument—each labeled “performative”—corresponding to two types of performatively self-falsifying proposition, and I compare them to modest transcendental arguments.

Strawson's philosophical attitude towards scepticism is frequently thought to have undergone a significant shift from the “strong” or “robust” employment of transcendental arguments in Individuals to a more “modest” understanding of the efficacy of such arguments in Skepticism and Naturalism: Some Varieties. I argue that this interpretation is based upon a misunderstanding of the function of transcendental arguments in Strawson's earlier works. Examining the continuity of Strawson's modest naturalistic approach to scepticism can offer some insight as to the continuing overestimation of the anti-sceptical efficacy of transcendental arguments.

In this volume of fourteen new essays, a distinguished team of philosophers offer a broad and stimulating examination of the nature, role, and value of transcendental arguments. Transcendental arguments aim to show that what is doubted or denied by the sceptic must be the case, as a condition for the possibility of experience, language, or thought. The essays consider how successful such arguments are as a response to sceptical problems.

Kantian transcendental arguments are aimed at uncovering the necessary conditions for the possibility of thought and experience. If such arguments are to have any force against Cartesian skepticism about knowledge of the external world, then it would seem that the conditions the transcendental argument uncovers must be non-psychological in nature, and their special status must be knowable a priori. In "Transcendental Arguments", Barry Stroud raised the question whether there are any such conditions., He answered that it was very doubtful that one could argue deductively from the premise that there is thought and experience to the conclusion that certain conditions concerning non-psychological, external reality are satisfied. In the intervening 27 years, no one has decisively answered those doubts. No one has succeeded in constructing a convincing Kantian anti- skeptical transcendental argument of the desired kind. In a recent paper, however, Stroud has suggested that things might well be looking up a bit for the transcendental arguer. Stroud now holds that there is a modest variant of the ambitious Kantian anti-skeptical strategy that offers the promise of an answer of sorts to the skeptic that is free of various objectionable Kantian excesses. In this paper, I will describe the more modest sort of transcendental argument that Stroud finds promising, and I will then raise some doubts about the prospects of this modest approach.

Transcendental arguments have been described as undogmatic or non-dogmatic arguments. This paper examines this contention critically and addresses the question of what is required from an argument for which the characterization is valid. I shall argue that although transcendental arguments do in certain respects meet what one should require from non-dogmatic arguments, they - or more specifically, what I shall call 'general transcendental arguments' - involve an assumption about conceptual unity that constitutes a reason for not attributing to them the status of non-dogmatic arguments. As a solution to this problem I distinguish general transcendental arguments from what I shall call 'specific transcendental arguments' and seek to explain how by limiting the use of transcendental arguments to the latter type it would be possible to avoid dogmatism. This methodological adjustment also opens up a possibility of re-interpreting transcendental arguments from the past in a novel non-dogmatic fashion.

Robert Stern investigates how scepticism can be countered by using transcendental arguments concerning the necessary conditions for the possibility of experience, language, or thought. He shows that the most damaging sceptical questions concern neither the certainty of our beliefs nor the reliability of our belief-forming methods, but rather how we can justify our beliefs.
