Dario Antiseri, an Italian philosopher who co-authored one of Italy’s most widely used philosophy textbooks, died Feb. 12, 2026. He was 86.
After graduating from the University of Perugia, Antiseri held teaching positions in Siena and Padova. In 1980, he collaborated with Giovanni Reale to publish Il Pensiero Occidentale dalle Origini ad Oggi. The multi-volume treatise became a standard text in Italian schools and was eventually translated into Spanish, Portuguese, and Russian.
Antiseri later served as a full professor of Methodology of the Social Sciences at LUISS in Rome. He was the Dean of the Faculty of Political Science at the university from 1994 to 1998. His work focused on the philosophy of science and scientific realism, and he published research connecting the concepts of fallibilism and hermeneutics.
In 2002, the University of Moscow awarded Antiseri an honorary degree in recognition of his work becoming a national bestseller in Russia. A scholar of Karl Popper and Hans-Georg Gadamer, he retired from his academic duties in 2010.
