Mr. Berger is uniquely qualified to lead people through this type of historical reexamination. He is critical of labels but identifies himself, among many other things, as Jewish and gay and counts the things he saw growing up among African-American children in a housing project on Manhattan's Lower East Side as some of his most formative experiences. In his 1999 book "White Lies: Race and the Myths of Whiteness," he uses the cumulative effect of vignettes, including stories from his childhood and interviews with other people, to expose the reader in private to the biases most of us cannot own up to in public. "For All the World to See" is presented with the same patience and precision. Here, too, the results are devastating.
