- Vasilis Politis (1997). The Apriority of the Starting-Point of Kant's Transcendental Epistemology. International Journal of Philosophical Studies 5 (2):255 – 284.The paper raises two questions, which seem central to understanding Kant's transcendental epistemology in the first Critique. First, Kant claims that the conditions for the possibility of experience are also conditions for the possibility of the objects of experience (A158/B197). Here the notion of an object is not conceived from the divine standpoint ('the view from nowhere') and is in some sense relativized to experience. But in what sense? Is the notion of an object relativized to one specific kind of experience, human experience? Or is it relativized only to any possible experience? Second, in what sense is Kant's transcendental epistemology a priori? Is it a priori in the strong sense that its starting-point - the notion of experience in the question 'How is experience possible?' - is a priori? Or is it a priori only in the weak sense that, while the notion of experience is obtained empirically, a priori reasoning is required to establish how experience is possible? It has recently been argued (by Patricia Kitcher, Kant's Transcendental Psychology) that (a) the results that Kant wants to establish transcenden-tally about objects are relative to one specific kind of experience, human experience, and (b) Kant's transcendental epistemology is a priori only in the weak sense that the reasoning is a priori, while the starting-point is empirical. These claims are indeed crucial to Kitcher's overall aim of naturalizing Kant's transcendental epistemology. The aim of the paper is to resist both claims. I argue that Kant's notion of an object of experience is the notion of an object of any possible experience, not the notion of an object of one specific kind of experience, human experience. It follows, I argue, that Kant's transcendental epistemology is a priori in the strong sense that its starting-point is a priori. If we deny strong apriority, we fail to account for Kant's move from the nature of experience to the nature of empirical reality: empirical reality as such, not empirical reality as experienced by a particular variety of creatures capable of experience. The upshot is that, for better or worse, Kant's transcendental epistemology cannot be naturalized.

In this paper I make use of Heidegger’s late essay, “Kant’s Thesis About Being,” in order to examine the structure of Kantian critique, the elusive transcendental method. Heidegger investigates the underlying reflective act that restricts “the use of the understanding to experience,” what Kant describes in an Appendix to the “Transcendental Analytic” of the Critique of Pure Reason as “transcendental reflection.” What is clear from Kant’s brief description is that prior to the analysis of the conditions of the possibility of experience, critical inquiry has designated the boundary of possible experience. While neither Kant nor Heidegger explicitly develops the account of the transcendental method that follows from this initial orienting act, doing so will offer a response to the charge, leveled at Kant since thepublication of the first Critique, that he was blind to the metaphysical presuppositions of transcendental idealism.

As most of its readers are aware, the Critique of Pure Reason is primarily concerned not with empirical, but with a priori knowledge. For the most part, the Kant of the first Critique tends to assume that experience, and the knowledge that is based on it, is unproblematic. The problem with which he is concerned is that of how we can be capable of substantive knowledge independently of experience. At the same time, however, the notion of experience plays a crucial role in the central arguments of the Critique. For, again as most readers of the Critique know, Kant aims to show how we can have synthetic a priori knowledge by showing that the categories, or pure concepts of the understanding, are conditions of the possibility of experience. This means that, whether or not Kant is concerned with the notion of experience for its own sake, his account of a priori knowledge carries with it at least some commitments regarding the character of experience. If the account of a priori knowledge is to be successful, then experience has to be the kind of thing for which the categories can, in principle, serve as conditions of possibility. More specifically, experience must involve not only the senses, but also thought or understanding, for otherwise the claim that it presupposes a certain specific set of concepts is simply unintelligible. And indeed at least some parts of the Critique, in particular the so-called subjective deduction in the first edition, and the briefer passages which correspond to it in the second edition, seem to be intended to show how this requirement is met. That is, they are concerned not so much with showing that experience is governed by the categories, as with elaborating a view of experience as involving conceptual activity überhaupt.
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.
The notion of the a priori underwent several changes since the time it came into existence in the Middle Ages. Originally it had been used to mark a certain form of argument, an argument that proceeds from what is prior to what is later, from cause to effect: demonstratio procedens ex causis ad effectum = demonstratio a priori. But this changed with Kant, for whom it meant not a form of argument but rather some special kind of knowledge (or elements thereof), namely knowledge that (a) is independent of particular experiences and (b) that makes experience in general (Erfahrung überhaupt) possible. Tied up with consciousness and the transcendental unity of apperception, Kant"s understanding of the a priori was in the spirit of his transcendental philosophy. But this understanding changed again with the rise of analytic philosophy, in which we still find the first characteristic but not the second anymore. The idea of Erfahrung überhaupt was given up, partly because one naturally wondered what exactly this notion of experience in general, or experience universally conceived, should be. Where should we get it from, if not by way of abstraction and generalization from individual cases of experience? And would this not make it an empirical concept, so that the whole project of asking for the conditions of its possibility would not lead us to the kind of certainty, necessity and universality we expect from a priori knowledge? There would be no guarantee that in the future we would not make discoveries that would give us new kinds of experiences or that would show us our experiences in a new light. Thus, we would have to admit that these experiences did not satisfy the conditions of experience we had set up originally. The a priori conditions would have to be revised.
This paper takes a fresh look at a classical theme in philosophical scholarship, the meaning of transcendental idealism, by contrasting Kant's and Husserl's versions of it. I present Kant's transcendental idealism as a theory distinguishing between the world as in-itself and as given to the experiencing human being. This reconstruction provides the backdrop for Husserl's transcendental phenomenology as a brand of transcendental idealism expanding on Kant: through the phenomenological reduction Husserl universalizes Kant's transcendental philosophy to an eidetic science of subjectivity. He thereby furnishes a new sense of transcendental philosophy, rephrases the quid iuris-question, and provides a new conception of the thing-in-itself. What needs to be clarified is not exclusively the possibility of a priori cognition but, to start at a much lower level, the validity of objects that give themselves in experience. The thing-in-itself is not an unknowable object, but the idea of the object in all possible appearances experienced at once. In spite of these changes Husserl remains committed to the basic sense of Kant's Copernican Turn. I end with some comments on how both Kant and Husserl view the relation between theoretical and moral philosophy.

This essay attempts a re-reading of the meaning and import of “synthetic propositions a priori” in the light of two other background concepts in Kantian epistemology: Erklärung and Begründung. The significance of this pair of concepts lies in the fact that they represent the “philosophical motive” of Kant---leading him, inevitably, to take the “transcendental turn”. (And, on this point, I believe that some commentators have reversed the dialectic of Kant’s thinking: they make him take the “transcendental turn” first, and then envision the Erklärung and the Begründung.) And the distinction between the “sensible world” and the “intelligible world” was the consequence. Did this distinction also provide the ontological matrix for the epistemological distinction between “analytic propositions” and “synthetic propositions”? I take that to be evident. What is less evident is that Kant was more interested in the relation between the two worlds than in these worlds in isolation. He was concerned with demonstrating the possibility (i.e., the “transcendental possibility” and not merely the “logical possibility”) of the sensible in the light of the intelligible. This he sought to do by elucidating (with the help of “transcendental arguments”) the a priori conditions of possible experience. This was the hidden dialectic of the transformation of the image of mind, from the Lockean “mirror” to the Kantian “prism”. The synthetic propositions a priori (I argue) articulate the relation of the a priori conditions of experience to the possible objects of experience. (That is why Kant takes the metaquestion, “How are synthetic propositions a priori possible?”, to be the main problem of the Kritik der reinen Vemunft.) The significance of the work of Kant for what we moderns call the “philosophy of science” is noted in the conclusion.

If the a priori is the proper subject matter of transcendental philosophy, then the problems of the a priori are also problems for transcendental philosophy. the idea that defines transcendental philosophy is the idea that there are stable general structures which are discernible in experience, provide the foundations of our knowledge of it, and collectively constitute an a priori which transcends experience and informs it. the a priori is traditionally conceived as a nexus of relations which is held to be logically/temporally prior to experience and responsible for its organization. in this essay, i challenge this traditional (kantian) understanding of the a priori and set forth an alternative to it based on the writings of maurice merleau-ponty. the intent is to provide a new conception of transcendental philosophy.
Kant''s claim that the justification of transcendental philosophy is a priori is puzzling because it should be consistent with (1) his general restriction on the justification of knowledge, that intuitions must play a role in the justification of all nondegenerate knowledge, with (2) the implausibility of a priori intuitions being the only ones on which transcendental philosophy is founded, and with (3) his professed view that transcendental philosophy is not analytic. I argue that this puzzle can be solved, that according to Kant transcendental philosophy is justified a priori in the sense that the only empirical information required for its justification can be derived from any possible human experience. Transcendental justification does not rely on any more particular or special observations or experiments. Philip Kitcher''s general account of apriority in Kant captures this aspect of a priori knowledge. Nevertheless, I argue that Kitcher''s account goes wrong in the link it specifies between apriority and certainty.
