Isaiah Berlin is one of the towering intellectual figures of the twentieth century, the most famous English thinker of the post-war era, and the focus of growing interest and discussion. Above all, he is one of the best modern exponents of the disappearing art of letter-writing. 'Life is not worth living unless one can be indiscreet to intimate friends, ' wrote Berlin to a correspondent. This first volume inaugurates a long awaited edition of his letters that might well adopt this remark as an epigraph. Berlin's life was well worth living, both for himself and for the world. Fortunately he said a great deal to his friends on paper as well as in person. Berlin's letters reveal the significant growth and development of his personality and career over the two decades covered within them. Starting with his days as an eighteen year old student at St. Paul's School in London, they cover his years at Oxford as scholar and professor and the authorship of his famous biography of Karl Marx. The letters progress to his World War II stay in the U.S. and finally, his trip to the Soviet Union in 1945-6 and return to Oxford in 1946. "Emotional exploitation, cannibalism, which I think I dislike more than anything else in the world." To Ben Nicolson, September 1937 "Valery delivered an agreeable but dull lecture here. He said words were like thin planks over precipices, and if you crossed rapidly nothing happened, but if you stopped on any of them and stared into the gulf you would get vertigo and that was what philosophers were doing." To Cressida Bonham Carter, March 1939 "I never don't moralize." To Mary Fisher, 18 April 1940 "I only feel happy when I feel the solidarity of the majority of people Irespect with and behind me." To Marion Frankfurter, 23 August 1940 "Certainly no politics are more real than those of academic life, no loves deeper, no hatreds more burning, no principles more sacred." To Freya Stark, 12 June 1944 "Nobody is so fiercely bureaucratic, or so stern with soldiers and regular civil servants, as the don disguised as temporary government official armed with an indestructible superiority complex." To Freya Stark, 12 June 1944 "My view on this is that you will not find life in the country lively enough for persons of your temperament. Life in the country in England depends entirely on (a) motor cars (b) rural tastes. As you possess neither, it is my considered view that apart from a weekend cottage or something of that sort, life in the country would bore you stiff within a very short time." To his parents, 31 January 1944 "This country is undoubtedly the largest assembly of fundamentally benevolent human beings ever gathered together, but the thought of staying here remains a nightmare." To his parents, 31 January 1944 "I am a hopeless dilettante about matters of fact really and only good for a column of gossip, if that." To W. J. Turner, 12 June 1945 "England is an old chronic complaint: every day in the afternoon in the left knee and the left leg below the kneecap, tiresome, annoying, not bad enough to go to bed with, probably incurable and madly irritating but not necessarily unlikely to lead to a really serious crisis unless complications set in." To Angus Malcolm, 20 February 1946

Now in one volume--"Berlin's most influential essays"
--Arthur Schlesinger, Jr., The Washington Post Book World

Isaiah Berlin was one of the leading thinkers of our time and one of its finest writers. The Proper Study of Mankind brings together his most celebrated writing: here the reader will find Berlin's famous essay on Tolstoy, "The Hedgehog and the Fox"; his penetrating portraits of contemporaries from Pasternak and Akhmatova to Churchill and Roosevelt; his essays on liberty and his exposition of pluralism; his defense of philosophy and history against assimilation to scientific method; and his brilliant studies of such intellectual originals as Machiavelli, Vico, and Herder.

In this collection of remarkable biographical portraits, the great essayist and intellectual historian Isaiah Berlin brings to life a wide range of prominent twentieth-century thinkers, politicians, and writers. These include Winston Churchill, Franklin D. Roosevelt, Chaim Weizmann, Albert Einstein, Virginia Woolf, Aldous Huxley, Boris Pasternak, and Anna Akhmatova. With the exception of Roosevelt, Berlin met them all, and he knew many of them well. Other figures recalled here include the Zionist Yitzhak Sadeh, the U.S. Supreme Court judge Felix Frankfurter, the classicist and wit Maurice Bowra, the philosopher J. L. Austin, and the literary critic Edmund Wilson. For this edition, ten new pieces have been added, including portraits of David Ben-Gurion, Maynard and Lydia Keynes, and Stephen Spender, as well as Berlin's autobiographical reflections on Jewish Oxford and his Oxford undergraduate years. Rich and enlightening, "Personal Impressions" is a vibrant demonstration of Berlin's belief that ideas truly live only through people.

"Out of the crooked timber of humanity, no straight thing was ever made."--Immanuel Kant

Isaiah Berlin was one of the most important philosophers of the twentieth century--an activist of the intellect who marshaled vast erudition and eloquence in defense of the endangered values of individual liberty and moral and political plurality. In "The Crooked Timber of Humanity" he exposes the links between the ideas of the past and the social and political cataclysms of our own time: between the Platonic belief in absolute truth and the lure of authoritarianism; between the eighteenth-century reactionary ideologue Joseph de Maistre and twentieth-century Fascism; between the romanticism of Schiller and Byron and the militant--and sometimes genocidal--nationalism that convulses the modern world.

This new edition features a revised text that supplants all previous versions, a new foreword in which award-winning novelist John Banville discusses Berlin's life and ideas, particularly his defense of pluralism, and a substantial new appendix that provides rich context, including letters by Berlin and previously uncollected writings, most notably his virtuoso review of Bertrand Russell's "A History of Western Philosophy."

With a revised foreword by Brookings President Strobe Talbott and a new introduction by Berlin's editor, Henry Hardy. George Kennan, the architect of US policy toward the Soviet Union, called Isaiah Berlin ""the patron saint among the commentators of the Russian scene."" In The Soviet Mind, Berlin proves himself fully worthy of that accolade. Although the essays in this book were originally written to explore the tensions between Soviet communism and Russian culture, the thinking about the Russian mind that emerges is as relevant today under Putin's postcommunist Russia as it was when this book first appeared more than a decade ago. This Brookings Classic brings together Berlin's writings about the Soviet Union. Among the highlights are accounts of Berlin's meetings with the Russian writers in the aftermath of the war; a celebrated memorandum he wrote for the British Foreign Office in 1945 about the state of the arts under Stalin; Berlin's account of Stalin's manipulative ""artificial dialectic""; portraits of Pasternak and poet Osip Mandel'shtam; Berlin's survey of Russian culture based on a visit in 1956; and a postscript reflecting on the fall of the Berlin Wall and other events in 1989. Henry Hardy prepared the essays for publication; his introduction describes their history. In his revised foreword, Brookings' Strobe Talbott, a longtime expert on Russia and the Soviet Union, relates the essays to Berlin's other work. The essays and other pieces in The Soviet Mind - which includes a new essay, ""Marxist versus Non-Marxist Ideas in Soviet Policy"" - represent Berlin at his most brilliant and are invaluable for policymakers, students, and anyone interested in Russian politics and thought - past, present, and future.

Isaiah Berlin's response to the Soviet Union was central to his identity, both personally and intellectually. Born a Russian subject in Riga in 1909, he spoke Russian as a child and witnessed both revolutions in St. Petersburg in 1917, emigrating to the West in 1921. He first returned to Russia in 1945, when he met the writers Anna Akhmatova and Boris Pasternak. These formative encounters helped shape his later work, especially his defense of political freedom and his studies of pre-Soviet Russian thinkers. Never before collected, Berlin's writings about the USSR include his accounts of his famous meetings with Russian writers shortly after the Second World War; the celebrated 1945 Foreign Office memorandum on the state of the arts under Stalin; his account of Stalin's manipulative 'artificial dialectic'; portraits of Osip Mandelshtam and Boris Pasternak; his survey of Soviet Russian culture written after a visit in 1956; a postscript stimulated by the events of 1989; and more. This collection includes essays that have never been published before, as well as works that are not widely known because they were published under pseudonyms to protect relatives living in Russia. The contents of this book were discussed at a seminar in Oxford in 2003, held under the auspices of the Brookings Institution. Berlin's editor, Henry Hardy, had prepared the essays for collective publication and here recounts their history. In his foreword, Brookings president Strobe Talbott, an expert on the Soviet Union, relates the essays to Berlin's other work. The Soviet Mind will assume its rightful place among Berlin's works and will prove invaluable for policymakers, students, and those interested in Russian politics, past, present and future.

"The fox knows many things, but the hedgehog knows one big thing." This ancient Greek aphorism, preserved in a fragment from the poet Archilochus, describes the central thesis of Isaiah Berlin's masterly essay on Leo Tolstoy and the philosophy of history, the subject of the epilogue to "War and Peace." Although there have been many interpretations of the adage, Berlin uses it to mark a fundamental distinction between human beings who are fascinated by the infinite variety of things and those who relate everything to a central, all-embracing system. Applied to Tolstoy, the saying illuminates a paradox that helps explain his philosophy of history: Tolstoy was a fox, but believed in being a hedgehog. One of Berlin's most celebrated works, this extraordinary essay offers profound insights about Tolstoy, historical understanding, and human psychology.

This new edition features a revised text that supplants all previous versions, English translations of the many passages in foreign languages, a new foreword in which Berlin biographer Michael Ignatieff explains the enduring appeal of Berlin's essay, and a new appendix that provides rich context, including excerpts from reviews and Berlin's letters, as well as a startling new interpretation of Archilochus's epigram.

'Brilliant. Searching and profound' E.H. Carr, Times Literary Supplement 'When reading Isaiah Berlin we breathe an altogether different air' New York Review of Books 'Beautifully written' W. H. Auden, New Yorker 'Ingenious. Exactly what good critical writing should be' Max Beloff, Guardian The fox knows many things, but the hedgehog knows one big thing. For Isaiah Berlin, there is a fundamental distinction in mankind: those who are fascinated by the infinite variety of things - foxes - and those who relate everything to a central all-embracing system - hedgehogs. It can be applied to the greatest creative minds: Dante, Ibsen and Proust are hedgehogs, while Shakespeare, Aristotle and Joyce are foxes. Yet when Berlin reaches the case of Tolstoy, he finds a fox by nature, but a hedgehog by conviction; a duality which holds the key to understanding Tolstoy's work, illuminating a paradox of his philosophy of history and showing why he was frequently misunderstood by his contemporaries and critics. With a foreword by Michael Ignatieff A W&N Essential

Isaiah Berlin's intellectual biography of Karl Marx has long been recognized as one of the best concise accounts of the life and thought of the man who had, in Berlin's words, a more "direct, deliberate, and powerful" influence on mankind than any other nineteenth-century thinker. A brilliantly lucid work of synthesis and exposition, the book introduces Marx's ideas and sets them in their context, explains why they were revolutionary in political and intellectual terms, and paints a memorable portrait of Marx's dramatic life and outsized personality. Berlin takes readers through Marx's years of adolescent rebellion and post-university communist agitation, the personal high point of the 1848 revolutions, and his later years of exile, political frustration, and intellectual effort. Critical yet sympathetic, Berlin's account illuminates a life without reproducing a legend.

New features of this thoroughly revised edition include references for Berlin's quotations and allusions, Terrell Carver's assessment of the distinctiveness of Berlin's book, and a revised guide to further reading.

Isaiah Berlin's translation reproduces in finely wrought English the original story's simplicity, lyricism, and sensitivity.

Required reading for fans of Tom Stoppard's "The Coast of Utopia"-the landmark investigation into Russian history and thought
Few, if any, English-language critics have written as perceptively as Isaiah Berlin about Russian thought and culture. "Russian Thinkers" is his unique meditation on the impact that Russia's outstanding writers and philosophers had on its culture. In addition to Tolstoy's philosophy of history, which he addresses in his most famous essay, "The Hedgehog and the Fox," Berlin considers the social and political circumstances that produced such men as Herzen, Bakunin, Turgenev, Belinsky, and others of the Russian intelligentsia, who made up, as Berlin describes, "the largest single Russian contribution to social change in the world."

The essays collected in this new volume reveal Isaiah Berlin at his most lucid and accessible. He was constitutionally incapable of writing with the opacity of the specialist, but these shorter, more introductory pieces provide the perfect starting-point for the reader new to his work. Those who are already familiar with his writing will also be grateful for this further addition to his collected essays.

The connecting theme of these essays, as in the case of earlier volumes, is the crucial social and political role--past, present and future--of ideas, and of their progenitors. A rich variety of subject-matters is represented--from philosophy to education, from Russia to Israel, from Marxism to romanticism--so that the truth of Heine's warning is exemplified on a broad front. It is a warning that Berlin often referred to, and provides an answer to those who ask, as from time to time they do, why intellectual history matters.

Among the contributions are "My Intellectual Path," Berlin's last essay, a retrospective autobiographical survey of his main preoccupations; and "Jewish Slavery and Emancipation," the classic statement of his Zionist views, long unavailable in print. His other subjects include the Enlightenment, Giambattista Vico, Vissarion Belinsky, Alexander Herzen, G.V. Plekhanov, the Russian intelligentsia, the idea of liberty, political realism, nationalism, and historicism. The book exhibits the full range of his enormously wide expertise and demonstrates the striking and enormously engaging individuality, as well as the power, of his own ideas.

"Over a hundred years ago, the German poet Heine warned the French not to underestimate the power of ideas: philosophical concepts nurtured in the stillness of a professor's study could destroy a civilization."--Isaiah Berlin, "Two Concepts of Liberty," 1958.

This new edition adds a number of previously uncollected pieces, including Berlin's earliest statement of the pluralism of values for which he is famous.

In this outstanding collection of essays, Isaiah Berlin, one of the great thinkers of the twentieth century, discusses the importance of dissenters in the history of ideas--among them Machiavelli, Vico, Montesquieu, Herzen, and Sorel. With his unusual powers of imaginative re-creation, Berlin brings to life original minds that swam against the current of their times--and still challenge conventional wisdom.

In a new foreword to this corrected edition, which also includes a new appendix of letters in which Berlin discusses and further illuminates some of its topics, noted essayist Mark Lilla argues that Berlin's decision to give up a philosophy fellowship and become a historian of ideas represented not an abandonment of philosophy but a decision to do philosophy by other, perhaps better, means. "His instinct told him," Lilla writes, "that you learn more about an idea as an idea when you know something about its genesis and understand why certain people found it compelling and were spurred to action by it." This collection of fascinating intellectual portraits is a rich demonstration of that belief.

In "The Roots of Romanticism," one of the twentieth century's most influential philosophers dissects and assesses a movement that changed the course of history. Brilliant, fresh, immediate, and eloquent, these celebrated Mellon Lectures are a bravura intellectual performance. Isaiah Berlin surveys the many attempts to define romanticism, distills its essence, traces its developments from its first stirrings to its apotheosis, and shows how it still permeates our outlook. He ranges over a cast of some of the greatest thinkers and artists of the eighteenth and nineteenth centuries, including Kant, Rousseau, Diderot, Schiller, the Schlegels, Novalis, Goethe, Blake, Byron, and Beethoven. The ideas and attitudes of these and other figures, Berlin argues, helped to shape twentieth-century nationalism, existentialism, democracy, totalitarianism, and our ideas about heroic individuals, self-fulfillment, and the exalted place of art.

This new edition, illustrated for the first time, also features a new foreword by philosopher John Gray, in which he discusses Berlin's belief that the influence of romanticism has been unpredictable and contradictory in the extreme, fuelling anti-liberal political movements but also reinvigorating liberalism; a revised text; and a new appendix that includes some of Berlin's correspondence about the lectures and the reactions to them.

Isaiah Berlin was deeply admired during his life, but his full contribution was perhaps underestimated because of his preference for the long essay form. The efforts of Henry Hardy to edit Berlin's work and reintroduce it to a broad, eager readership have gone far to remedy this. Now, Princeton is pleased to return to print, under one cover, Berlin's essays on these celebrated and captivating intellectual portraits: Vico, Hamann, and Herder. These essays on three relatively uncelebrated thinkers are not marginal ruminations, but rather among Berlin's most important studies in the history of ideas. They are integral to his central project: the critical recovery of the ideas of the Counter-Enlightenment and the explanation of its appeal and consequences--both positive and (often) tragic.

Giambattista Vico was the anachronistic and impoverished Neapolitan philosopher sometimes credited with founding the human sciences. He opposed Enlightenment methods as cold and fallacious. J. G. Hamann was a pious, cranky dilettante in a peripheral German city. But he was brilliant enough to gain the audience of Kant, Goethe, and Moses Mendelssohn. In Hamann's chaotic and long-ignored writings, Berlin finds the first strong attack on Enlightenment rationalism and a wholly original source of the coming swell of romanticism. Johann Gottfried Herder, the progenitor of populism and European nationalism, rejected universalism and rationalism but championed cultural pluralism.

Individually, these fascinating intellectual biographies reveal Berlin's own great intelligence, learning, and generosity, as well as the passionate genius of his subjects. Together, they constitute an arresting interpretation of romanticism's precursors. In Hamann's railings and the more considered writings of Vico and Herder, Berlin finds critics of the Enlightenment worthy of our careful attention. But he identifies much that is misguided in their rejection of universal values, rationalism, and science. With his customary emphasis on the frightening power of ideas, Berlin traces much of the next centuries' irrationalism and suffering to the historicism and particularism they advocated. What Berlin has to say about these long-dead thinkers--in appreciation and dissent--is remarkably timely in a day when Enlightenment beliefs are being challenged not just by academics but by politicians and by powerful nationalist and fundamentalist movements.

The study of J. G. Hamann was originally published under the title "The Magus of the North: J. G. Hamann and the Origins of Modern Irrationalism." The essays on Vico and Herder were originally published as "Vico and Herder: Two Studies in the History of Ideas." Both are out of print.

This new edition includes a number of previously uncollected pieces on Vico and Herder, two interesting passages excluded from the first edition of the essay on Hamann, and Berlin's thoughtful responses to two reviewers of that same edition.

Joseph de Maistre's Considerations on France is the best known French equivalent of Edmund Burke's Reflections on the Revolution in France. This new edition of Richard Lebrun's 1974 translation is introduced by Isaiah Berlin, with a bibliography and chronology by the translator. Published in 1797, the work of the self-exiled Maistre presents a providential interpretation of the French Revolution and argues for a new alliance of throne and altar under a restored Bourbon monarchy. Although the Directory and then Napoleon delayed Maistre's influence within France until the Restoration, he is now acknowledged as the most eloquent spokesperson for continental conservatism. Considerations on France was a shrewd piece of propaganda, but, as Isaiah Berlin contends, by arguing his case in broad historical, philosophical and religious terms, Maistre raises issues of enduring importance.

These celebrated lectures constitute one of Isaiah Berlin's most concise, accessible, and convincing presentations of his views on human freedom--views that later found expression in such famous works as "Two Concepts of Liberty" and were at the heart of his lifelong work on the Enlightenment and its critics. When they were broadcast on BBC radio in 1952, the lectures created a sensation and confirmed Berlin's reputation as an intellectual who could speak to the public in an appealing and compelling way. A recording of only one of the lectures has survived, but Henry Hardy has recreated them all here from BBC transcripts and Berlin's annotated drafts. Hardy has also added, as an appendix to this new edition, a revealing text of "Two Concepts" based on Berlin's earliest surviving drafts, which throws light on some of the issues raised by the essay. And, in a new foreword, historian Enrique Krauze traces the origin of Berlin's idea of negative freedom to his rejection of the notion that the creation of the State of Israel left Jews with only two choices: to emigrate to Israel or to renounce Jewish identity.

A New York Times Notable Book of the Year "For anyone wanting to understand the twists and turns of the history of ideas, this book will be indispensable." John Gray, New York Times Book Review The Sense of Reality was the last new collection of essays published by Isaiah Berlin in his lifetime. All informed by Berlin's lifelong fascination with the history of ideas, these engaging studies range widely: the subjects explored include realism in history; judgment in politics; the history of socialism; the nature and impact of Marxism; the radical cultural revolution instigated by the Romantics; Russian notions of artistic commitment; and the origins and practice of nationalism. The title essay, taking its cue from the impossibility of recreating a bygone epoch, is a superb centerpiece. Now with a new foreword by Timothy Snyder and a new appendix comprising a previously unpublished essay on the great Russian critic Vissarion Belinksy and a previously uncollected lecture on utopianism, The Sense of Reality is a rich and illuminating collection from one of the most seductive writers and thinkers of the twentieth century.

A New York Times Notable Book of the Year

Isaiah Berlin's The Sense of Reality contains an important body of previously unknown work by one of our century's leading historians of ideas, and one of the finest essayists writing in English. Eight of the nine pieces included here are published for the first time, and their range is characteristically wide: the subjects explored include realism in history; judgement in politics; the history of socialism; the nature and impact of Marxism; the radical cultural revolution instigated by the Romantics; Russian notions of artistic commitment; and the origins and practice of nationalism. The title essay, starting from the impossibility of historians being able to recreate a bygone epoch, is a superb centerpiece.

'He becomes everyman's guide to everything exciting in the history of ideas' New York Review of Books Isaiah Berlin was one of the leading thinkers of the twentieth century, and one of the finest writers. The Proper Study Of Mankind selects some of his best essays in which his insights both illuminate the past and offer a key to the burning issues of today. The full (and enormous) range of his work is represented here, from the exposition of his most distinctive doctrine - pluralism - to studies of Machiavelli, Tolstoy, Churchill and Roosevelt.

Isaiah Berlin's celebrated radio lectures on six formative anti-liberal thinkers were delivered on the BBC's Third Programme in 1952. They are published here for the first time, fifty years on. Freedom and its Betrayal? is one of Isaiah Berlin's earliest and most convincing expositions of his views on human freedom and the history of ideas, views which later found expression in such famous works as 'Two Concepts of Liberty', and were at the heart of his lifelong work on the Enlightenment and its critics.

In his lucid examinations of sometimes difficult ideas Berlin demonstrates that a balanced understanding and a resilient defence of human liberty depend on learning both from the errors of freedom's alleged defenders and from the dark insights of its avowed antagonists. This book throws light on the early development of Berlin's ideas, and supplements his already published writings with fuller treatments of Helvétius, Rousseau, Fichte, Hegel and Saint-Simon, with the ultra-conservative traditionalist Maistre bringing up the rear.

Freedom and its Betrayal shows Berlin at his liveliest and most torrentially spontaneous, testifying to his talents as a teacher of rare brilliance and impact. Listeners tuned in expectantly each week to the broadcasts and found themselves mesmerised by Berlin's astonishingly fluent extempore style. A leading historian of ideas, who was then a schoolboy, records that the lectures 'excited me so much that I sat, for every talk, on the floor beside the wireless, taking notes'. This excitement is at last recreated here for all to share.

The Roots of Romanticism at last makes available in printed form Isaia h Berlin's most famous lecture series, the Mellon Lectures, delivered in Washington in 1965, recorded by the BBC, and broadcast several time s. A published version has been keenly awaited ever since the lecture s were given, and indeed Berlin had always hoped to complete a book ba sed upon them. But, despite extensive further work, this hope was not fulfilled, and this book is an edited transcript of his spoken words. For Berlin, the Romantics set in train a vast unparalleled revolu tion in humanity's view of itself. They destroyed the traditional not ions of objective truth and validity in ethics, with incalculable, all -pervasive results. As he said of them elsewhere: 'the world has neve r been the same since, and our politics and our morals have been deepl y transformed by them. Certainly this has been the most radical, and indeed terrifying. . . change in men's outlook in modern times. ' In these brilliant lectures Berlin surveys the myriad attempts to define Romanticism, distils its essence, traces its development from its first stirrings to its unbridled apotheosis, and shows how its las ting legacy permeates our contemporary outlook.

Liberty is an expanded edition of Isaiah Berlin's classic of liberalism, Four Essays on Liberty. Berlin's editor Henry Hardy has incorporated a fifth essay, as Berlin wished, and added further pieces on the same topic, so that Berlin's principal statements on liberty are available together for the first time. He also describes the gestation of the book and throws further biographical light on Berlin's preoccupation with liberty in appendices drawn from his unpublished writings.
