Liberty is a new, expanded edition of what Isaiah Berlin himself regarded as his most important book - Four Essays on Liberty, a standard text of liberalism and constantly in demand since it was first published in 1969. Berlin's editor, Henry Hardy, has revised the text, incorporating a fifth essay that Berlin himself had hoped to include. He has also added further pieces that bear on the same topic, so that all Berlin's principal statements on liberty are at last available (...) together in one volume. (shrink)
