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 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.
