The relation between transcendental idealism and philosophical naturalism awaits more careful determination, i. e. whether the issue of their compatibility hinges on their ontological view on the relation between physical and mental phenomena (i. e. whether it is supervenience or emergence) or on their epistemological view on our access to mental content. The aim of this paper is to identify a tension between transcendental idealism and philosophical naturalism, which lies not in their ontological view on the nature of substances, but (...) in their epistemological view on the relation between self-awareness and the first-personal access to mental content. I will first trace the (mis)understanding of transcendental idealism as Berkeleyan idealism to a misinterpretation of the self-knowledge premise in transcendental arguments. I will argue that transcendental idealism is not so much concerned with grounding reality of the external world as with establishing the agential nature of the first-personal perspective of experience, and it has an important implication on the meaning and function of self-awareness in transcendental idealism.

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. (shrink)

In this essay, I argue that Wittgenstein attempted to clarify ethics through a procedure that, by analogy with “transcendental arguments”, I call “transcendental thought experiment”. Specifically, after offering a brief perspectival account of both transcendental arguments and transcendental thought experiments, I focus on a thought experiment proposed by Wittgenstein in his 1929 'Lecture on Ethics', arguing that it deserves the title of “transcendental”.

In A Theory of Justice (1971), John Rawls introduces the concept of “reflective equilibrium.” Although there are innumerable references to and discussions of this concept in the literature, there is, to the present author's knowledge, no discussion of the most important question: Why reflective equilibrium? In particular, the question arises: Is the method of reflective equilibrium applicable to the choice of this method itself? Rawls's drawing of parallels between Kant's moral theory and his own suggests that his concept of “reflective (...) equilibrium” is on a par with Kant's concept of “transcendental deduction.” Treating these two approaches to justification as paradigmatic, I consider their respective merits in meeting the reflexive challenge, i.e., in offering a justification for choice of mode of justification. My enquiry into this topic comprises three parts. In the first part (Eng 2014a), I raised the issue of the reflexivity of justification and questioned whether the reflexive challenge can be met within the framework of A Theory of Justice. In this second part, I shall outline a Kantian approach that represents a paradigmatic alternative to Rawls. (shrink)

Kant’s doctrine of the Fact of Reason is one of the most perplexing aspects of his moral philosophy. The aim of this paper is to defend Kant’s doctrine from the common charge of dogmatism. My defense turns on a previously unexplored analogy to the notion of ‘matters of fact’ popularized by members of the Royal Society in the seventeenth century. In their work, ‘facts’ were beyond doubt, often referring to experimental effects one could witness first hand. While Kant uses the (...) German equivalent in different contexts, I argue that the scientific analogy opens up a new framework for interpreting his strategy of justification in the Critique of Practical Reason. In the final section, I address a few possible objections to my reading, one of which I anticipate coming from Dieter Henrich and Ian Proops, who have argued that Kant’s Fact of Reason is best understood under a legal analogy.
