 Thereafter, variations on Berlin’s account of pluralism appear throughout his writings on Romanticism. Late in his life, taking stock of his career, and trying to communicate what he felt to be his most important philosophical insights, Berlin increasingly devoted himself to the explicit articulation and refinement of pluralism as an ethical theory. He had referred in a private letter of 1968 (Ignatieff 1998, 246) to ‘the unavoidability of conflicting ends’ as his one genuine discovery. He devoted the lecture he gave in accepting the Agnelli Prize in 1988, ‘The Pursuit of the Ideal’, to explaining what pluralism meant, and this remains the most eloquent and concentrated summary of pluralism. Berlin also discussed pluralism in many interviews and printed exchanges with other scholars from the 1970s onward, in an attempt to work through the conflicts, controversies and confusions to which his ideas gave rise; but many of these resisted Berlin’s attempts at resolution, and continue to figure in, and sometimes dominate, discussions of his work.
