Dario Antiseri, a prominent Italian philosopher known for his contributions to science and liberal thought, has passed away in Cesi di Terni after a prolonged illness. Born in Foligno in 1940, Antiseri studied at the University of Perugia before advancing his education in various European institutions. He became a notable follower of philosopher Karl Popper, working to disseminate Popper's ideas in Italy, including through his renowned biography of the philosopher which was published by Rubbettino. Antiseri's application of scientific rationalism, derived from Popper's epistemology, influenced his extensive work in multiple fields.

Antiseri was not just an intellectual giant; he was also recognized as a generous and affable individual with a deep commitment to individual freedom. Unlike the traditional Catholic liberals of the 19th century, such as Antonio Rosmini or Alessandro Manzoni, Antiseri forged a unique philosophical path. As a Catholic and a liberal, he emphasized personal liberty as a crucial aspect of his beliefs, advocating for a worldview that harmonized faith in Christ with a profound respect for freedom. His original perspective set him apart in the landscape of contemporary thought.

The passing of Dario Antiseri leaves behind a significant void in the academic and philosophical community, particularly among those who value the interplay between faith and freedom. His contributions to the study of logical positivism and his engagement with the works of Karl Popper have paved the way for future discussions on the relationship between science, religion, and individual rights. As a scholar and thinker who bridged these domains, Antiseri's legacy will continue to inspire generations of philosophers and students alike.
