"Political Ideas in the Twentieth Century", Historical Inevitability", "Two Concepts of Liberty", "John Stuart Mill and the Ends of Life". These four essays deal with the various aspects of individual liberty, including the distinction between positive and negative liberty and the necessity of rejecting determinism if we wish to keep hold of the notions of human responsibility and freedom.

In his much quoted, seminal work, On Liberty, John Stuart Mill attempts to establish standards for the relationship between authority and liberty. He emphasizes the importance of individuality which he conceived as a prerequisite to the higher pleasures-the summum bonum of Utilitarianism. Published in 1859, On Liberty presents one of the most eloquent defenses of individual freedom and is perhaps the most widely-read liberal argument in support of the value of liberty.

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.

Since his death in 1997, Isaiah Berlin’s writings have generated continual interest among scholars and educated readers, especially in regard to his ideas about liberalism, value pluralism, and "positive" and "negative" liberty. Most books on Berlin have examined his general political theory, but this volume uses a contemporary perspective to focus specifically on his ideas about freedom and liberty. Isaiah Berlin and the Politics of Freedom brings together an integrated collection of essays by noted and emerging political theorists that commemorate in a critical spirit the recent 50th anniversary of Isaiah Berlin’s famous lecture and essay, "Two Concepts of Liberty." The contributors use Berlin’s essay as an occasion to rethink the larger politics of freedom from a twenty-first century standpoint, bringing Berlin’s ideas into conversation with current political problems and perspectives rooted in postcolonial theory, feminist theory, democratic theory, and critical social theory. The editors begin by surveying the influence of Berlin’s essay and the range of debates about freedom that it has inspired. Contributors’ chapters then offer various analyses such as competing ways to contextualize Berlin’s essay, how to reconsider Berlin’s ideas in light of struggles over national self-determination, European colonialism, and racism, and how to view Berlin’s controversial distinction between so-called "negative liberty" and "positive liberty." By relating Berlin’s thinking about freedom to competing contemporary views of the politics of freedom, this book will be significant for both scholars of Berlin as well as people who are interested in larger debates about the meaning and conditions of freedom.

"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.
