'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. In these pages he encapsulates the principal movements that characterise the modern age- romanticism, historicism, Fascism, relativism, irrationalism and nationalism. His ideas are always tied to the people who conceived them, so that abstractions are brought alive. EDITED BY HENRY HARDY AND ROGER HAUSHEER AND WITH A NEW FOREWORD BY ANDREW MARR
