Nathan Glazer is Emeritus Professor of Education and Sociology at Harvard University. He is the author of numerous books, including We Are All Multiculturalists Now, The Limits of Social Policy, Beyond the Melting Pot, and The Lonely Crowd (with David Riesman). He was one of the co-founders of The Public Interest.
The assumption behind the claim to multicultural equality or to acceptance of diversity is not that differences will merge and disappear, but that they will continue.
