Berlin was the only surviving child of a wealthy Jewish family, the son of Mendel Berlin, a timber industrialist and direct descendant of Shneur Zalman (founder of Chabad Hasidism), and his wife Marie, née Volshonok. He spent his childhood in Riga (then part of the Russian Empire; now capital of Latvia), and later lived in Andreapol´ (a small timber town near Pskov, effectively owned by the family business) and Petrograd, witnessing both the February and October Revolutions of 1917.

Feeling increasingly oppressed by life under Bolshevik rule, the family left Saint Petersburg on October 5, 1920, for Riga, but encounters with anti-Semitism and difficulties with the Latvian authorities convinced them to leave, and they moved to Britain in early 1921 (Mendel in January, Isaiah and Marie at the beginning of February), when Berlin was eleven. In London, the family first stayed in Surbiton, then within the year they bought a house in Holland Park, and six years later in Hampstead. Berlin's English was virtually nonexistent at first, but he became fluent within a year.

Berlin was educated at St Paul's School , then at Corpus Christi College, Oxford, where he studied Greats (Classics). In his final examinations, he took a First, winning The John Locke Prize for his performance in the philosophy papers, in which he outscored even A. J. Ayer. He subsequently took another degree at Oxford in PPE (Philosophy, Politics and Economics), winning another First after less than a year on the course. He was appointed a tutor in philosophy at New College, Oxford, and soon afterwards was elected to a prize fellowship at All Souls College, Oxford.

While still a student, he notably befriended Sir A. J. Ayer (with whom he was to share a friendly rivalry for the rest of his life), Sir Stuart Hampshire, Richard Wollheim, Sir Maurice Bowra, Sir Stephen Spender, J. L. Austin, Christopher Isherwood and Nicolas Nabokov. In 1940 he presented a philosophical paper on other minds to a meeting attended by Ludwig Wittgenstein at Cambridge University. Wittgenstein rejected his paper in discussion but praised Berlin for his intellectual honesty and integrity. Berlin was to remain at Oxford for the rest of his life, apart from a period working for British Information Services in New York from 1940 to 1942, and for the British embassies in Washington, DC, and Moscow from then until 1946. Berlin was fluent in Russian and English, spoke French, German and Italian, and knew Latin and Ancient Greek. Meetings with Anna Akhmatova in Leningrad in autumn 1945 and January 1946 had a powerful effect on both of them, and serious repercussions for Akhmatova (who immortalised the meetings in her poetry). He befriended Boris Pasternak, and was responsible for smuggling a typescript of Doctor Zhivago out of Russia to England. In 1956, he married Aline Halban, née de Gunzbourg, who was from an exiled half Russian-aristocratic and half ennobled-Jewish banking and petroleum family (her mother was Yvonne Deutsch de la Muerthe) based in Paris.

Berlin died in Oxford in 1997, aged 88. He is buried there in Wolvercote Cemetery. On his death, the front page spread ofThe Independent wrote: "he was a man of formidable intellectual power with a rare gift for understanding a wide range of human motives, hopes and fears, and a prodigiously energetic capacity for enjoyment - of life, of people in all their variety, of their ideas and idiosyncrasies, of literature, of music, of art." The front page of The New York Times concluded: "His was an exuberant life crowded with joys – the joy of thought, the joy of music, the joy of good friends ... The theme that runs throughout his work is his concern with liberty and the dignity of human beings ... Sir Isaiah radiated well-being."

"Two Concepts of Liberty"

Berlin is popularly known for his essay "Two Concepts of Liberty", delivered in 1958 as his inaugural lecture as Chichele Professor of Social and Political Theory at Oxford. The essay, with its analytical approach to the definition of political concepts, re-introduced the study of political philosophy to the methods of analytic philosophy. Spurred by his background in the philosophy of language, Berlin argued for a nuanced and subtle understanding of our political terminology, where what was superficially understood as a single concept could mask a plurality of different uses and therefore meanings. Berlin argued that these multiple and differing concepts, otherwise masked by rhetorical conflations, showed the plurality and incompatibility of human values, and the need for us to distinguish and trade off analytically between, rather than conflate, them, if we are to avoid disguising underlying value-conflicts.

Counter-Enlightenment

Berlin's writings on the Enlightenment and its critics (especially Giambattista Vico, Johann Gottfried Herder, Joseph de Maistre and Johann Georg Hamann) – for whom Berlin used the concept of "the Counter-Enlightenment" – contributed to his advocacy of an irreducibly pluralist ethical ontology. In Three Critics of the Enlightenment, Berlin argued that Hamann was one of the first thinkers to conceive of human cognition as language – the articulation and use of symbols. Berlin saw Hamann as having recognised as the rationalist's Cartesian fallacy the notion that there are "clear and distinct" ideas "which can be contemplated by a kind of inner eye", without the use of language – a recognition greatly sharpened in the 20th century by Wittgenstein's private language argument.

Value pluralism

For Berlin, values are creations of mankind, rather than products of nature waiting to be discovered. He argued, on the basis of the epistemic and empathetic access we have to other cultures across history, that the nature of mankind is such that certain values — for example, the importance of individual liberty — will hold true across cultures, and this is what he meant when he called his position "objective pluralism". Berlin's argument was partly grounded in Wittgenstein's later theory of language, which argued that inter-translatability was supervenient on a similarity in forms of life, with the inverse implication that our epistemic access to other cultures entails an ontologically contiguous value-structure. With his account of value pluralism, he proposed the view that moral values may be equally, or rather incommensurably, valid and yet incompatible, and may therefore come into conflict with one another in a way that admits of no resolution without reference to particular contexts of decision. When values clash, it may not be that one is more important than the other. Keeping a promise may conflict with the pursuit of truth; liberty may clash with social justice. Moral conflicts are "an intrinsic, irremovable element in human life". "These collisions of values are of the essence of what they are and what we are." For Berlin, this incommensurate clashing of values within, no less than between, individuals, constitutes the tragedy of human life.

"The Hedgehog and the Fox"

"The Hedgehog and the Fox", a title referring to a fragment attributed to the ancient Greek poet Archilochus, was one of Berlin's most popular essays with the general public, reprinted in numerous editions. Of the essay, Berlin once said "I never meant it very seriously. I meant it as a kind of enjoyable intellectual game, but it was taken seriously."

Other work

Berlin's essay "Historical Inevitability" (1954) focused on a controversy in the philosophy of history. Given the choice, whether one believes that "the lives of entire peoples and societies have been decisively influenced by exceptional individuals" or, conversely, that whatever happens occurs as a result of impersonal forces oblivious to human intentions – Berlin rejected both options and the choice itself as nonsensical. Berlin is also well known for his writings on Russian intellectual history, most of which are collected in Russian Thinkers (1978; 2nd ed. 2008), edited, like most of Berlin's work, by Henry Hardy (in the case of this volume, jointly with Aileen Kelly).

Wolfson College

Isaiah Berlin was instrumental in the founding, in 1966, of a new graduate college at Oxford University. Berlin founded Wolfson College to be a centre of academic excellence which, unlike many other colleges at Oxford, would also be based on a strong egalitarian and democratic ethos.
