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.

Within much contemporary epistemology, Kant’s response to skepticism has come to be epitomized by an appeal to transcendental arguments. This form of argument is said to provide a distinctively Kantian way of dealing with the skeptic, by showing that what the skeptic questions is in fact a condition for her being able to raise that question in the first place, if she is to have language, thoughts, or experiences at all. In this way, it is hoped, the game played by the skeptic can be turned against herself.1 At the same time, however, this appeal to transcendental arguments is also widely felt to show what is wrong with Kant’s response to skepticism: for, it is suggested, such arguments can only be made to work against the background of his transcendental idealism. As we shall see, what this doctrine amounts to is much disputed; but as with any form of idealism, the worry is that it means compromising the very realism and objectivity we want to defend against skepticism in the first place, so that the price for adopting this Kantian strategy appears too high—the cure of using transcendental arguments in conjunction with transcendental idealism is almost as bad as the disease.2 Faced with this difficulty, two kinds of response have been canvassed. On the first, it is accepted that transcendental arguments do require a commitment to the wider philosophical framework of transcendental idealism, but it is claimed that this framework can and should be defended against the suggestion that it is itself ‘‘quasi-skeptical.’’ On the second, transcendental idealism is indeed abandoned as wrongheaded, but it is held that Kant’s transcendental arguments can be made to..

A Kantian transcendental argument is an argument which purports to show that the existence of physical objects of a certain general character is a condition for the possibility of self-conscious experience. Both the Transcendental Deduction and the Refutation of Idealism satisfy this characterization. But we have seen that even a successful Kantian transcendental argument would be somewhat disappointing. Even though such an argument would refute the extreme Cartesian skepticism about the very existence of physical objects, it would not certify any of one's claims to know facts about particular physical objects: it would not refute the weaker skeptical position I have sketched.5 How- ever, it would clearly be of great interest if one could show that the existence of physical objects is a condition for the possibility of self- conscious experience. Accordingly, I would like to investigate some problems surrounding the construction of Kantian transcendental arguments.

The interpretation of transcendental arguments remains a contentious issue for contemporary epistemology. It is usually agreed that they originated in Kant's theoretical philosophy and were intended to have some kind of anti-sceptical efficacy. I argue that the sceptic with whom Kant was concerned has been consistently misidentified. The actual sceptic was Hume, questioning whether the faculty of reason can justify any of our judgements whatsoever. His challenge is a sceptical argument regarding rule-following which engenders a vicious regress. Once this sceptical threat is properly identified, the prospects of transcendental arguments must be re-evaluated.

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.

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.

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.

A modest transcendental argument is one that sets out merely to establish how things need to appear to us or how we need to believe them to be, rather than how things are. Stroud's claim to have established that all transcendental arguments must be modest in this way is criticised and rejected. However, a different case for why we should abandon ambitious transcendental arguments is presented: namely, that when it comes to establishing claims about how things are, there is no reason to prefer transcendental arguments to arguments that rely on the evidence of the senses, making the former redundant in a way that modest transcendental arguments, which have a different kind of sceptical target, are not.
