Ideologie et langage en Italie (L. Formigari) The author notes the influence of the Ideologists, after that of Condillac, on linguistic studies in Italy, in spite of the suspicion aroused by the materalist views that are supposed to accompany their philosophical positions. As early as 1796, there appears a trend of thought close to Ideology, which aims at theorizing on the relationship between language, society and culture. This was a fundamental problem for a country that had not yet found its linguistic or political unity. The substantial bibliography in this article brings up numerous points concerning research on the influence of the Ideologists.
