In these essays Deutscher speaks of the emotional heritage of the European Jew with a calm clear-sightedness. As a historian he writes without religious belief, but with a generous breadth of understanding; as a philosopher he writes of some of the great Jews of Europe: Spinoza, Heine, Marx, Trotsky, Luxemburg, and Freud. He explores the Jewish imagination through the painter Chagall. He writes of the Jews under Stalin and of the "remnants of a race" after Hitler, as well as of the Zionist ideal, of the establishment of the state of Israel, of the Six-Day War, and of the perils ahead.
