Philippe-Joseph Salazar (1955) is a French rhetorician and philosopher. Former student of Derrida and Barthes, formerly responsible for the seminar "Rhetoric and democracy" of the International College of Philosophy of Paris, is a professor at the University of Cape Town. In line with the French rhetoric school of Marc Fumaroli, he has written numerous essays, including Mahomet (2005), L'hyperpolitique (2009) and Paroles de leaders (2011). "Salazar considers that Western governments make many mistakes in the fight against jihadists, and the first one is to misinterpret propaganda speech without understanding how it seduces young people who need genuine emotions" (La Cité). "The speech of the Islamic State is much more subtle than we would like to believe. This is the conclusion of the rhetorician Philippe-Joseph Salazar, who has carefully heard and read the propagandists of the Caliphate "(Bertrand Rothé, Le Mondes des Livres). "Salazar tries to stand before the mirror in this struggle in which, while we continue to reflect on whether Daesh is written with" s "or" c ", if we should write it as EI or IS, they continue to recruit tens of thousands of young people" ( The world).
