Desmond Carolan Fennell (29 June 1929 – 16 July 2021) was an Irish writer, essayist, cultural philosopher and linguist. Throughout his career, Fennell repeatedly departed from prevailing norms. In the 1950s and early 1960s, with his extensive foreign travel and reporting and his travel book ,Mainly in Wonder, he departed from the norm of Irish Catholic writing at the time. From the late 1960s into the 1970s, in developing new approaches to the partition of Ireland and the Irish language revival, he deviated from political and linguistic Irish nationalism, and with the philosophical scope of his Beyond Nationalism: The Struggle against Provinciality in the Modern World, from contemporary Irish culture generally.
