Philippe Gruca graduated with a Master's degree in sociology from EHESS in Paris, writing a thesis on the anthropological theory of Philippe Descola, as well as a Master's degree in Philosophy from the University of Paris 1 Panthéon-Sorbonne, on the question the size of human societies. His research, however, led him to the “philosophical anthropology” of Günther Anders and his Diskrepanzphilosophie, examining the human being immersed in modernity and overtaken by technology.
Quadrilingual (French, Polish, English, and German), Philippe Gruca also teaches Negotiation, within the NGO Rational Games; French at the Technical University of Berlin; Philosophy and Rhetoric, within the atelier français, his own structure; and soon also psychology, within the Sigmund Freud PrivatUniversität.
Between 2012 and 2015, he directed the “Theoretical and Political Degrowth Journal” Entropia with Serge Latouche and Alice Canabate. Its historical director, Jean-Claude Besson-Girard, was an admirer of Jean Malaurie and, like him, a fervent defender of indigenous societies. On the occasion of Jean Malaurie's 100th birthday, in 2022, Jan Borm asked Philippe Gruca to reactivate and direct with them the prestigious “International Journal of Arctic Studies”, Inter-Nord, founded in 1960.
