AbstractThis work aims to enhance the contribution of Aurelio Peccei to Futures Studies and its unaltered relevance in the light of the world's current scientific issues. Peccei's contribution in Futures Studies is often identified with his propulsive role in the birth of the Club of Rome (1968) and in the promotion of the report "The Limits to Growth" (1972). Although this would be enough to make him a central figure in the history of Futures Studies, his whole intellectual journey is worth emphasizing. This work focuses on the "epistemic impact" of Peccei in the field research on possible futures. Peccei not only argued the fundamental need to translate complexity into a forecasting model: as an ante litteram anticipator, he dedicated his life to seek a development model respecting both the human tendency towards constant evolution and biosphere. A theoretical impact that allowed many fundamental UN initiatives—from the 1987 Report of the World Commission on Environment and Development to the 2015 Report on Sustainable Development Goals (SDGs)—and also helped the development of a forward-looking social research
