Robustly realistic metaphysical readings of Kant’s mature views have become popular in recent years, largely because of the apparent coherence of applying unschematized categories like that of causation to things in themselves. There is, however, an overlooked problem that arises even for robust realist readings that privilege unschematized categories. The problem is that Kant provides all the elements for what is now called a ‘debunking explanation’ of metaphysical representations of things in themselves. His account of the categories as arising from (...) mere forms of judgment, and being applied primarily for the unity of consciousness, is detached from the issue of whether there are causes among things in themselves. This detachment seems to imply that it would be a huge coincidence if unschematized categories corresponded to any such causes. After making this argument, using the category of causation as my central case, I consider three potential responses: that Kant’s account implicitly appeals to things in themselves’ causation, that Kant has a separate account of non-coincidental representation, and that Kant’s account is merely incomplete in a way that poses no debunking threat. None of these responses, I argue, are successful, so I conclude that either robustly realistic metaphysical readings are mistaken, or there is internal incoherence in Kant’s views. (shrink)

I begin by considering a question that has driven much scholarship on transcendental idealism: are appearances numerically identical to the things in themselves that appear, or numerically distinct? I point out that much of the debate on this question has assumed that this is equivalent to the question of whether they are the same objects, but go on to provide textual, historical, and philosophical evidence that “object” (Gegenstand) and “thing” (Ding) have different meanings for Kant. A thing is a locus (...) of intensively gradable causal force, reality. I argue that appearances and things in themselves are not identical as objects, because the very concept of object-identity is tied, for Kant, to the concept of an intellect that would cognize the numerical identity of the objects in question. Because no intellect can be both discursive and intellectual, no intellect could cognize the numerical identity of objects across the phenomenal/noumenal divide, and thus the claim that they are identical has no content. However, the very same things, the same reality, can be given to our sensible intellects, and to divine intuitive intellect, as two non-overlapping domains of objects. Identity readers are thus shown to be right about the same thing relation, while non-identity readers are vindicated on the numerical identity of objects. (shrink)

Interpreters of Kant’s Refutation of Idealism face a dilemma: it seems to either beg the question against the Cartesian sceptic or else offer a disappointingly Berkeleyan conclusion. In this article I offer an interpretation of the Refutation on which it does not beg the question against the Cartesian sceptic. After defending a principle about question-begging, I identify four premises concerning our representations that there are textual reasons to think Kant might be implicitly assuming. Using those assumptions, I offer a reconstruction (...) of Kant’s Refutation that avoids the interpretative dilemma, though difficult questions about the argument remain. (shrink)

This article presents a metaphysical approach to the interpretation of the role of things-in-themselves in Kant’s theoretical philosophy. This focuses upon identifying their transcendental function as the grounding of appearances. It is interpreted as defining the relation of appearing as the grounding of empirical causality. This leads to a type of dual-aspect account that is given further support through a detailed examination of two sections of Kant’s first Critique. This shows the need to embed this dual-aspect account within a two-perspective (...) framework. The resulting picture is contrasted with the main rival theories and objections are addressed.

The book addresses two main areas of Kant’s theoretical philosophy: the doctrine of transcendental idealism and various central aspects of the arguments from the Metaphysical and Transcendental Deductions, as well as the relation between the deduction argument and idealism. -/- Among the topics covered are the nature of objective validity, the role and function of transcendental logic in relation to general or formal logic, the possibility of contradictory thoughts, the meaning of the Leitfaden at A79 and the unity of cognition, (...) the two-steps-in-one-proof interpretation and categorial instantiation, categorial illusion, Strawson’s transcendental argument, the persistently perplexing question of the derivation of the categories, and the relation between apperception, objectivity, judgement, and idealism. -/- With regard to idealism in particular, the focus is on the metaphysical two-aspect interpretation and its problems, on the merits and demerits of the controversial phenomenalist reading of Kant’s idealism, and on the topic of subjectivism and epistemic humility. -/- In all of the aforementioned topics, the book presents wholly novel interpretations compared to the standard or mainstream interpretations.

This article offers the first systematic investigation of the linguistic forms in which Kant expresses his transcendental idealism since Gerold Prauss’ seminal book Kant und das Problem der Dinge an sich. It is argued that Prauss’ own argument for the claim that ‘in itself’ is an adverbial expression that standardly modifies verbs of philosophical reflection is flawed and that there is hence very poor exegetical evidence for so-called ‘methodological two-aspect’ interpretations of Kant’s transcendental idealism. A comprehensive investigation of Kant’s adverbial (...) uses of ‘in itself’ rather reveals that there are various groups of verbs that ‘in itself’ modifies, which can more or less all be reduced to a standard use in which ‘in itself’ modifies verbs of predicative being such as the copula. It is also discussed how these findings can be accommodated by the two main alternative kinds of interpretations, that is, two-object and ontological two-aspect interpretations. (shrink)

The word “as” enables one to make contexts and aspects of things explicit while attributing properties or descriptions to them. For example “John is rational as a mathematician”; “John is irrational as a driver.” This paper examines the idea according to which all propositions containing “as” should be targeted as potential inferences about the subject; as for the examples given—about John. If the inference is valid—the conception in question holds—one can get rid of “as.” I argue against that view by (...) bringing up several contexts in which “as” is not supposed to express an inference. On this basis I come up with a different (non-inferential) typology which does justice, I believe, to ordinary as well as philosophical uses of the little word at stake. (shrink)

Qualifiers such as “insofar as” and “in itself” have always been important ingredients in key philosophical claims. Descartes, for instance, famously argues that insofar as he is a thinker, he is not made of matter, and Kant equally famously argues that we cannot know things in themselves. Neither of these claims is meant to be true without qualification. Descartes is not simply denying that humans consist of matter, and Kant is not simply denying that we know things. Therefore, we cannot (...) even begin to understand such claims without knowing how qualifiers work. Unlike the logic of quantification, however, the logic of qualification is rather underexplored. In this paper, I examine several instances of philosophical uses of qualifiers, taken from Aristotle, Avicenna, Descartes, Kant, and 20th c. action theory. In the light of these examples, I discuss several accounts of how such qualifiers work. (shrink)

My dissertation proposes a novel interpretation of Kant’s doctrine of transcendental idealism as presented in the Critique of Pure Reason. I aim to give a consensus interpretation by overcoming past errors in interpreting this doctrine. I support my interpretation through a textual exegesis of the Critique of Pure Reason with a special focus on the direct and indirect proofs of transcendental idealism. Transcendental idealism is the doctrine that objects of our experience, space, and time, when taken as they would be (...) outside our possible experience, are nothing but mere representations. However, this does not make them into illusions. This is because Kant takes objects of our experience, space, and time to be empirically real. Empirical realism is the doctrine that objects of our experience, space, and time, when taken within our possible experience, exist independently of us. Yet, their empirical reality is not grounded in things in themselves, about whose existence Kant is agnostic. Instead, the reality of objects of our experience, space, and time depend on a standard of empirical reality that differs from the standard of transcendental reality. This separate standard of empirical reality allows Kant to hold transcendental idealism and empirical realism at the same time. Finally, while not strictly part of the doctrine of transcendental idealism, I answer the question of the relation of appearances and things in themselves. The distinction between appearances and things in themselves is a metaphysical distinction between two different ways of being, i.e., objectivity, properties, existence, reality. Yet, this is a metaphysical distinction within the same concept of an object. Thus, appearances and things in themselves are the same object conceptually that is determined metaphysically in two different ways. (shrink)

Los noumena son, en principio, conceptos límites. En el corpus kantiano encontramos múltiples de ellos, cuyo papel es decisivo en el tratamiento de la metafísica anterior, así como en la propuesta de metafísicas alternativas. Kant, sin embargo, no se detiene a explicarnos de dónde surgen esos conceptos y dónde irían. La presente investigación sugiere que a partir del concepto de nota (Merkmal) presentada en la KrV y desarrollada en la Jäsche Logik, podemos comprender estos noumena como las notas analíticas, suficientes, (...) esenciales y primitivas de las ideas de la razón, tanto teóricas como prácticas.
