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.
