The Ukrainian philosopher Constantin Sigov, who heads the European Center at Mohyla University in Kiev, was associate director of studies at the Ecole des hautes études en sciences sociales (EHESS) in Paris from 1992 to 1995. He contributed to the establishment of the European Vocabulary of Philosophies (Paris, Seuil/Le Robert, 2004) and founded the publishing house Duh i litera (Spirit and Letter) in Kiev, which published authoritative Ukrainian translations of such great thinkers as Montaigne, Descartes, Pascal, Paul Ricoeur, Emmanuel Levinas and François Furet. A friend of Paul Ricoeur and Charles Taylor, he had them at the University of Kiev. For his tireless activity as a bridge builder between cultures, Constantin Sigov was decorated by France with the rank of Officer of the Order of Academic Palms. In 2014, he supported the Maidan Revolution, of which he was a leading voice. His personal work as a thinker, which occupies a major place in the Slavic world, meets a lively international echo.
