As is well known, the linguistic/philosophical reflection on natural kind terms has undergone a remarkable development in the early seventies with Putnam and Kripke’s essentialist approaches, touching upon different aspects of Kan’s slant. Preliminarily, however, it might be useful to review some of the theoretical stages in Locke and Leibniz’s approaches on natural kind terms in the light of contemporary reflections, to eventually pinpoint Kant’s contribution and see how some commentators have placed it within the theory of direct reference. Starting (...) with textual evidence even from the logical corpus, in the present essay I will attempt to discuss some of the arguments dismissing Kant’s adherence to this view. These assume that in his approach to the semantics of natural kind Kant appears to be still holding on to a nominalist/conceptualist position, though he seems to be well aware of a few key issues for the theorists of direct reference.

[full article, abstract in English; abstract in Lithuanian] The question whether Kant is a conceptualist has attracted significant attention of Kant scholars in recent decades. I present all three dominant positions in the debate and argue that strong conceptualism and nonconceptualism are less plausible interpretations of Kant’s philosophy. I argue that the first cannot explain Kant’s commitments related to the incongruents, animals, and infants. The second one, meanwhile, cannot explain Kant’s argument on causation against Hume. At the end of the (...) paper, I try to show that the key to a plausible and convincing interpretation of Kant as a weak conceptualist is the distinction between categories and empirical concepts.
