In The Disuniting of America: Reflections on a Multicultural Society, Revised and Enlarged Edition (W. W. Norton) Schlesinger provides deep insights into the crises of nationhood in America. A new chapter assesses the impact both of radical multiculturalism and radical monoculturalism on the Bill of rights. Written with his usual clarity and force, the book brings a noted historian' s wisdom and perspective to bear on America' s "culture wars".

Schlesinger addresses the questions: What holds a nation together？ And what does it mean to be an American？ Describing the emerging cult of ethnicity, Schlesinger praises its healthy effect on a nation long shamed by a history of prejudice and narrow-mindedness. But he warns against the campaign of multicultural advocates to divide the nation into separate ethnic and racial communities. From the start, he observes, the United States has been a multicultural nation, rich in its diversity but held together by a shared commitment to the democratic process and by the freedom of intermarriage. It was this national talent for assimilation that impressed foreign visitors like Alexis de Tocqueyille and James Bryce, and it is this historic goal that Schlesinger champions as the best hope for the future. Schlesinger analyzes what he sees as grim consequences of identity politics: the widening of differences. Attacks on the First Amendment, he argues, threaten intellectual freedom and, ultimately, the future of the ethnic groups. His criticisms are not limited to the left. As a former target of McCarthyism, be understands that the radical right is even more willing than the radical left to re strict and weaken the Bill of Rights.

The author does not minimize the injustices concealed by the "melting pot" dream. The Disuniting of America is both academic and personal, forceful in argument, balanced in judgment. It is a book that will no doubt anger some readers, but it will surely make all of them think again. The winner of Pulitzer Prizes for history and for biography, an authoritative voice of American liberalism, Schlesinger is uniquely positioned to bring bold answers and healing wisdom to this passionate debate over who we are and what we should become.

According to Schlesinger, the United States is ______.

A．a melting pot
