My research project aims to promote the study of Peter Szondi's hermeneutic thought, highlighting the tools it offers to the human sciences. My research traces the history of Szondi's critical hermeneutics in the Franco-German region, putting it into perspective with its reception in Italy, as well as in English-, Spanish-, and Portuguese-speaking countries. The aim of this study is twofold: on the one hand, it seeks to decompartmentalize hermeneutic research by exploring its implications for the humanities and social sciences as well as for the political life of communities; on the other hand, it aims to contribute to the study of the transnational and transregional history of the humanities, particularly in the Franco-German context. In this context, hermeneutics is usually associated with the Heideggerian tradition. However, the hermeneutics developed by Peter Szondi from the 1950s onwards, in opposition to this philosophical hermeneutics, remains underexplored. Its political significance, which lies in its ability to reconcile a rigorous interpretation of texts with an original reflection on the historicity of writings and their truth value, is still often overlooked. Drawing on the study of cultural transfers (M. Espagne, M. Werner), my research incorporates both textual interpretation and socio-historical study to understand the emergence and development of this thought across the linguistic and cultural spaces mentioned above. This study is based primarily on an analysis of Szondi's writings, their translations, and documents attesting to the transfer of his thought, as well as on interviews with those involved in these transfers.
