The theme of this contribution is the relationship between language and concept in Hyppolite’s interpretation of Hegel. This issue is addressed starting from two questions: what are the ontological conditions that make language possible; whether language has an originally transcendental status. After an analysis of the genesis of language, the investigation focuses on the self-reflexivity of language itself. Thus the basic thesis is developed, which can be summarized in the following points: the self-reflexivity of language implies the immanence of being at appearing; this implication requires a review of the Hegelian systematic organization, a review in which emerges the central role of Lehre vom Wesen; and only on the basis of this centrality, language can perform an originally transcendental function.
