There is a growing interest in both Kant’s conception of philosophy and contemporary metaphilosophy, understood as philosophical inquiry into philosophy, its aims, purpose, subjects, structure, practice and methods. Kant has not contributed to metaphilosophy qua contemporary discipline, but his direct analyses of what philosophy is and how it is to be done can be identified with general subjects and problems constituting the research field of metaphilosophy. Several aspects of Kant’s conception of philosophy and its metaphilosophical value are the subject of current debates, such as the taxonomy of philosophy, relation between empirical and non-empirical philosophy, relation between philosophy and its history, conceptual analysis, deductive reasoning and philosophical disagreement.

Kant’s metaphilosophy has three main parts: (1) an essentialist project (“What is philosophy?”); (2) a methodological project (“How do we do philosophy?”); and (3) a taxonomic project (“What are the different parts of philosophy, and how are they related?”). This paper focuses on the third project. In particular, it explores one of the most intriguing yet puzzling aspects of Kant’s philosophy, viz. the relationship between what Kant calls ‘pure’ philosophy vs. ‘applied’, ‘empirical’ or what we can broadly refer to as ‘impure’ philosophy. (As we shall see, in order to be able to address this third project, we shall also need to examine the other two projects in detail.) My plan is as follows. First, I discuss four main areas of pure vs. impure philosophy: (i) ‘pure logic’ vs. ‘applied logic’; (ii) ‘rational psychology’ vs. ‘empirical psychology’; (iii) ‘pure metaphysics of nature’ vs. ‘physics’ and (iv) ‘pure morality’ or a ‘metaphysics of morals’ vs. ‘moral anthropology’, ‘practical anthropology’ or ‘applied moral philosophy’. Based on this, I identify four key differences between pure and impure philosophy. Second, I critically examine four different readings of Kant’s views about the status of ‘impure’ philosophy: (a) that it is not genuine philosophy; (b) that it is bad or inferior philosophy; (c) that it is instrumentally valuable; and (d) that it constitutes an indispensable part of Kant’s philosophy, both in a theoretical and practical sense. I argue that Kant is best interpreted as endorsing readings (c) and (d). Third, I offer some concluding remarks.

In the current dialogue between two authors with different views on analysis, philosophy, and the use of labels, the leading question is: How should one understand the expression ‘analytic philosophy’? Lewin argues that as there are no generally agreed tenets and methods of what is being called ‘analytic philosophy’, the name is to be replaced by a more specific one or abandoned. Williamson defends the use of this phrase, claiming that it is quite serviceable, as it relates to a broad tradition of influence, while it is not even required to adhere to the method of analysis in any distinctive sense. Lewin counters that, in this case, ‘analytic philosophy’ is too empty. One could heal this by conceptual analysis of ‘analytic philosophy’ — but then Kant, for whom philosophy is inherently analytic, would be a proponent of analytic philosophy. Another option is to follow Ryle’s ideal of a label-free, coherent and honest thinking. As Lewin argues, Williamson’s views seem at least partially to agree with Kant’s conception of the difference between philosophy and history of philosophy as well as empirical analysis and the underlying empirical realism. Williamson replies that he uses ‘analytic philosophy’ in its current meaning, which is not composed of the meanings of ‘analytic’ and ‘philosophy’. The current use is different from the earlier ones and not applicable to Kant. He argues against the transcendental idealism and the coarse-grained distinction between analytic and synthetic and a priori and a posteriori that requires an update.

My aim is to reconstruct the basic steps and the fundamental idea of Kant’s transcendental deduction of categories as well as Hegel’s interpretation and reframing of Kant’s idea. Hegel’s reading is crucial for two reasons: first, for fixing the basic form of the Kant­ian argument and secondly, for understanding its metaphilosophical relevance. For Hegel, philosophical proof has a specific nature, which distinguishes it from scientific proof and brings it closer to a juridical one. In this perspective the transcendental deduction, which is universally considered one of the most difficult chapters in the history of philosophy, reveals itself as the genuine clarification of specifically philosophical proof. I first present the idea of Kant’s transcendental deduction in the Critique of Pure Reason as well as its Hegelian reading in the Science of Logic and reformulation as the very method of philosophy in the Philo­sophy of Right. I show what in the Kantian argumentation constituted the basis for Hegel’s own interpretation and transformation. In so doing, I highlight a ‘red thread’ between the two ideas of the transcendental deduction. I conclude by proposing a formal account of Kant’s and Hegel’s ideas and by summing up the main metaphilosophical insights we can gain from Kant’s idea and its Hegelian interpretation.

Throughout history, both philosophers and non-philosophers have doubted that philosophical positions qua philosophical positions are justified and that philosophy is a rational enterprise. Today, such doubts are grouped under the term “Metaphilosophical Skepticism”. Nicholas Rescher, in his book Strife of Systems, includes Kant among the proponents of this kind of skepticism. I want to argue that while Rescher is wrong, Kant has con­tributed to a new version of such skepticism. In the first step, I characterize the basic idea of metaphilosophical skepticism in more detail and identify a version of this idea, which I call “Second-Stage-Skepticism” and on which I will focus. In the following part, I reconstruct Rescher’s reading of Second-Stage-Skepticism as well as his reasons for considering Kant to represent this version. My main claim in this part will be that there is no reading of the mentioned basic idea that makes Rescher’s view reasonable. In the third step, I introduce a newer form of metaphilosophical skepticism — “Third-Stage Skepticism” — and conjecture that this form can be seen as inspired by Kant’s thought on philosophical diversity. Finally, I point out a way to reject this newer form.
