The Philosophy of Isaiah Berlin

Isaiah Berlin’s lecture on political liberty ‘Two Concepts of Liberty’ (1958) created a new standard for understanding the individual and society. It has become a classic work. What set it apart was not so much that an Oxford don was prepared to engage directly and polemically with a theme of near-universal human concern but the way in which its author explored political morality itself. His account of liberty refused to conform to the narrow scope of ordinary academic discourse. Berlin sought to treat our personal and public lives in the only way he felt they can be grasped, that is, as reflecting our interaction with ideas and ideals in their particular historical context. What his approach exposed was not simply the ethical emptiness and practical uselessness of the prevailing philosophical schools of logical positivism and linguistic analysis; it also provided an example of the sort of understanding, even knowledge, that can emerge from exploring political values such as liberty, equality and justice through a genuinely humanistic and historical but no less analytically rigorous lens. In short, he produced a uniquely arresting political theory for real human beings.
