Kant soutient qu’une table complète et systématique des catégories peut être établie selon le « fil conducteur » des fonctions logiques du jugement. La première partie de cet article est une exposition de l’argument kantien. La deuxième partie est un examen de quelques-unes des objections formulées à l’encontre du « fil conducteur » de Kant. Je conclus que l’appropriation contemporaine de la doctrine kantienne des catégories est désormais divisée entre deux problèmes distincts : celui du contenu conceptuel (ou non) de la perception, et celui des structures conceptuelles présupposées par une image scientifique particulière du monde.

Le présent essai tente de tirer au clair les différentes significations des termes « conscient » et « conscience » dans la philosophie critique de Kant et en particulier dans la Critique de la raison pure. On considère d’abord les divers types de représentations et ce que veut dire Kant lorsqu’il les dit « avec » ou « sans » conscience. On considère ensuite le concept de conscience tel qu’il apparaît dans la Déduction transcendantale des catégories, où il ne réfère pas à une qualité de représentations particulières, mais à une attitude active de l’esprit. Considérée dans son ensemble, la conception kantienne de la « conscience » mêle inséparablement un aspect que nous appelons, après T. Nagel, « conscience phénoménale », et un aspect proche de la « conscience d’accès » selon N. Block, dans lequel cependant la conscience de soi, exprimable par la proposition « Je pense », joue un rôle central. Cette combinaison fait de Kant un interlocuteur unique dans les débats contemporains sur la conscience et son rôle dans notre vie mentale, ainsi que sur l’IA et sa signification pour l’avenir de l’humanité.

What do we express when we use the first-person pronoun 'I' in phrases such as 'I think' or 'I ought to'? Do we refer to ourselves as biologically unique, socially determined individuals? Or do we express a consciousness of ourselves as the bearers of thoughts we share, or can share, with all other human beings whatever their particular biological, social, or cultural background? Every year the Faculty of Philosophy at the University of Amsterdam invites a prominent philosopher to occupy the Spinoza Chair and give two public lectures on a topic in philosophy. Beatrice Longuenesse, in these lectures, explores the contrast and complementarity between these two aspects of the use of 'I'. Her first lecture considers the first-person pronoun in relation to the exercise of our mental capacities in abstract reasoning, and in relation to our knowledge of objective facts about the world. Her second lecture explores the use of 'I' in relation to what we take to be our moral obligations. In bringing together these two fascinating lectures, this book presents contrasting aspects of the self as radically individual on the one hand, and as the bearer of universally shared capacities on the other.

Béatrice Longuenesse presents an original exploration of our understanding of ourselves and the way we talk about ourselves. In the first part of the book she discusses contemporary analyses of our use of 'I' in language and thought, and compares them to Kant's account of self-consciousness, especially the type of self-consciousness expressed in the proposition 'I think.' According to many contemporary philosophers, necessarily, any instance of our use of 'I' is backed by our consciousness of our own body. For Kant, in contrast, 'I think' just expresses our consciousness of being engaged in bringing rational unity into the contents of our mental states. In the second part of the book, Longuenesse analyzes the details of Kant's view and argues that contemporary discussions in philosophy and psychology stand to benefit from Kant's insights into self-consciousness and the unity of consciousness. The third and final part of the book outlines similarities between Kant's view of the structure of mental life grounding our uses of 'I' in 'I think' and in the moral 'I ought to, ' on the one hand; and Freud's analysis of the organizations of mental processes he calls 'ego' and 'superego' on the other hand. Longuenesse argues that Freudian metapsychology offers a path to a naturalization of Kant's transcendental view of the mind. It offers a developmental account of the normative capacities that ground our uses of 'I, ' which Kant thought could not be accounted for without appealing to a world of pure intelligences, distinct from the empirical, natural world of physical entities.

According to Kant, the rationalist notion of a person as a thinking substance, conscious of its own identity through time, trades on an ambiguity concerning the meaning of ‘being conscious of the numerical identity of oneself at different times’. I argue that against the rationalist notion, Kant endorses the notion of a person as a spatio-temporal entity endowed with unity of apperception and capable of knowing its own identity through time according to empirical criteria of identification and re-identification. Nevertheless, Kant maintains that the rationalist notion is both ‘necessary and sufficient for practical use’. I argue that in fact, Kant's empirical notion of a person was sufficient even for the purposes of his moral philosophy. I conclude by comparing my analysis of the strengths and weaknesses of Kant's view with Peter Strawson's analysis of Kant's argument in the Paralogisms of Pure Reason.

Kant famously declares that “although all our cognition commences with experience, … it does not on that account all arise from experience”. This marks Kant’s disagreement with empiricism, and his contention that human knowledge and experience require both sensation and the use of certain a priori concepts, the Categories. However, this is only the surface of Kant’s much deeper, though neglected view about the nature of reason and judgment. Kant holds that even our a priori concepts are acquired, not from sensation, but “originally,” because our mind has a fundamental capacity to judge that, upon sensory stimulation, generates the Categories through its basic logical functions of judgment. This “epigenesis” of reason and our fundamental capacity to judge that drives it is the topic of Longuenesse’s fascinating book, and the source of her title.

In the 82/2 (2000) issue of this journal, Michael Friedman has offered a stimulating discussion of my recent book, Kant and the Capacity to Judge. His conclusion is that on the whole I fail to do justice to what is most revolutionary about Kant's natural philosophy, and instead end up attributing to Kant a pre-Newtonian, Aristotelian philosophy of nature. This is because, according to Friedman, I put excessive weight on Kant's claim to have derived his categories from a set of logical forms of judgment which he inherits from a traditional Aristotelian logic. In taking Kant at his word on this point, I fail to give their full import to Kant's insights into the newly discovered applications of mathematical concepts and methods to the science of nature.
