Kant: Judgment of Perception vs Judgment of Experience

Few of Kant’s distinctions have generated as much puzzlement and criticism as the one he draws in the Prolegomena between judgments of experience, which he describes as objectively and universally valid, and judgments of perception, which he says are merely subjectively valid. Yet the distinction between objective and subjective validity is central to Kant’s account of experience and plays a key role in his Transcendental Deduction of the categories. In this paper, I reject a standard interpretation of the distinction, according (...) to which judgments of perception are merely subjectively valid because they are made without sufficient investigation. In its place, I argue that for Kant, judgments of perception are merely subjectively valid because they merely report sequences of perceptions had by a subject without claiming that what is represented by the perceptions is connected in the objects the perceptions are of. Whereas the interpretation I criticize undercuts Kant’s strategy in the Deduction, I argue, my interpretation illuminates it. (shrink)

Subjective judgments and judgments about subjects. A distinction regarding judgments of perception [English] It is well known the number of problems that arise from the distinction between "judgments of perception" and "judgments of experience" delivered in the Prolegomena. This article focuses on the impossibility of assigning truth value to judgments of perception since it seems counterintuitive to indicate that judgments such as "I am cold" or "sugar tastes sweet" cannot be true. To solve this difficulty, it is proposed here to (...) distinguish between true judgments of perception (true subjective judgments) and "judgments about subjects". The latter would be those that, despite referring in a certain sense to a subject, do so using categorical links and, therefore, are judgments of experience with claims of objective validity and with truth value. However, there is another reason for this distinction besides solving the difficulty posed. Above all, it is important to offer a key to understand the true nature of judgments of perception, showing the impossibility of understanding them as judgments that describe subjective mental states, and trying to distinguish the way in which we enunciate them from the merely subjective unit that, according to Kant, characterizes them. To carry out these objectives, we will first analyze the basis of the distinction between perception judgments and experience judgments; secondly, a distinction between subjective judgments and judgments about subjects is proposed and explained, while the role of truth in the empirical illusion is examined; and finally, we will underline the impossibility of formulating judgments (including those of perceptions) independently of any objective link. [Español] Es moneda común la diversidad de problemas que plantea la introducción de la distinción entre “juicios de percepción” y “juicios de experiencia” en los Prolegómenos. Este trabajo centra su atención en la imposibilidad de asignar valor de verdad a juicios de percepción —dada su carencia de pretensión de validez objetiva— pues parece contraintuitivo indicar que juicios como “tengo calor” o “el azúcar me sabe dulce” no pueden ser verdaderos. Para solucionar esta dificultad, se propone aquí distinguir entre los verdaderos juicios de percepción (verdaderos juicios subjetivos) y “juicios sobre sujetos”. Estos últimos serían aquellos que, a pesar de referirse en cierto sentido a un sujeto, lo hacen con enlaces categoriales y, por tanto, son en realidad juicios de experiencia con pretensión de validez objetiva y con valor de verdad. Sin embargo, a esta distinción subyace otro motivo además de solucionar la dificultad planteada. Interesa, sobre todo, ofrecer una clave para comprender la verdadera naturaleza de los juicios de percepción, mostrando la imposibilidad de entenderlos como juicios que describen estados mentales subjetivos, e intentando distinguir la forma en que los enunciamos de la unidad meramente subjetiva que, según Kant, los caracteriza. Para llevar a cabo estos objetivos se analiza, primero, el fundamento de la distinción entre juicios de percepción y juicios de experiencia; en segundo lugar, se propone y explica la distinción entre juicios subjetivos y juicios sobre sujetos, a la par que se examina el papel de la verdad en la ilusión empírica; y por último se subraya la imposibilidad de formular juicios (incluso de percepción) independientemente de cualquier enlace objetivo.

In order to secure the limits of the critical use of reason, and to succeed in the critique of speculative metaphysics, Immanuel Kant (1724–1804) had to present a full account of human cognitive experience. Perception in Kant’s Model of Experience is a detailed investigation of this aspect of Kant’s grand enterprise with a special focus: perception. The overarching goal is to understand this common phenomenon both in itself and as the key to understanding Kant’s views of experience. In the process, (...) the author argues against any such reading of Kant that puts too much emphasis on concepts and understanding in perception. This means that claims of the sort that intuitions cannot play their role without concepts, that sensibility cannot bring anything to cognition without being mediated through the functions of understanding, or that there is no such thing as concept-independent perception, are shown to be either plainly false or misleading at best. Together with the contemporary topics examined by the end of the book, the findings suggest how the role of conceptual thinking in human cognition has been exaggerated partly because of a misplaced interpretation of Kant, which not only makes perception far more intellectual in character than what was intended by Kant himself, but distorts Kant’s account of cognition by overlooking what there is at the heart of his critical philosophy: the revaluation of sensible cognition.

Many scholars claimed that, according to Immanuel Kant, some judgements lack a truth-value: analytic judgements, judgements about items of which humans cannot have experience, judgements of perception, and non-assertoric judgements. However, no one has undertaken an extensive examination of the textual evidence for those claims. Based on an analysis of Kant's texts, I argue that: (1) according to Kant, only judgements of perception are not truth-apt. All other judgements are truth-apt, including analytic judgements and judgements about items of which humans (...) cannot have experience. (2) Kant sometimes states that truth-apt judgements are actual bearers of truth or falsity only when they are taken to state what is actually the case. Kant calls these judgements assertoric. Other texts ascribe truth and falsity to judgements, regardless of whether they are assertoric. Kant's views on truth-aptness raise challenges for correspondentist and coherentist interpretations of Kant's theory of truth; they rule out the identification of Kant's crucial notion of objective validity with truth-aptness; and they imply that Kant was not a verificationist about truth or meaning.
