This special issue of Nordicum-Mediterraneum contains the proceedings of the international conference entitled “‘Us’ vs. ‘Them’: The rhetoric of ‘othering’ from Aristotle to Frank Westerman”, which was held at the University of Genoa, Italy, in November 2018. Hosted by the Department of Philosophy and chaired by Prof. Mirella Pasini, the conference commemorated the 10th anniversary of the death of Prof. Flavio Baroncelli (1944-2007), a long-time teacher at the University of Genoa, a famed public figure in the Italian media of his time, an accomplished specialist in moral philosophy, and a forceful promoter of teacher- and student-exchanges between Iceland and Italy.
