The main point for criticizing the Cartesians for Vico is the notion of method, interpreted as exceptionally discursive procedure, devoid of spontaneity and creative force which are necessary for discovering new truths. These qualities are embodied for Vico in the Latin term ingenium, loan translation of which is found in Italian (ingegno) and is absent in French. The criticism of Cartesianisn suggested by Vico does not consider the fundamental bilingualism of this philosophy and wide use of the term ingenium in (...) the corps of Descartes’ Latin works. The analysis of the latter proves that the early Descartes’ notion intuitus mentis, as well as the concept of natural light of mind are, in the end, based exactly on ingenium, but not on the discursive methodical procedures. Human soul, following Descartes, reveals its content in several hypostastes and each method of revelation corresponds to specific terminology. Soul as mens is not the same as soul as ingenium. But even the early Descartes’ study of soul is marked by peculiar nominalism, proclamation of the real existence of individual soul as a separate entity. Therefore later, stating his ego cogito, Descartes states exactly the individual substance, not thinking in general. The terminological couple ingenium/mens is not translatable already in the French texts of Descartes himself (both merge in the French esprit), however their Ukrainian translations do not consider neither this untranslatability nor obvious references of Descartes’ esprit to other Latin compliances which differ each time. The article also analyses frequency in usage of the terms ingenium and mens in early and late Descartes’ Latin works; it has been proved that the augmentation of the meaning of metaphysical problems gradually turned mens into the main subject of Descartes’ research and deactualised the problem of ingenium.
