Abstract :
While Isaiah Berlin considered himself principally as a political theorist in the liberal tradition, his was an unorthodox liberalism in both method and substance, rooted in the confluence of three traditions—British, Russian, and Jewish. Unlike many liberals, he wrestled with the tension between universalism and particularism, and also between individualism and communalities. He rejected all monistic approaches to morality (including liberal monism) but repudiated as well the moral relativism of much modern thought, espousing instead value pluralism. While we cannot arrive at a universally valid conception of the summum bonum, we can specify the summun malum—the great evils of the human condition. Berlin saw political theory as a branch of moral philosophy but drew political morality from political life rather than imposing it on politics. The range of goods and principles that human beings rightly prize cannot be combined into harmonious wholes in either our individual or collective existence. Some goods exclude others, and we must choose among them.
