Professor, Stanford Law School, from the article "Are you White Enough?"
The problem with race as Americans understand it is that it doesn't really exist. It is a brutal fact of life for millions of citizens, and an inescapable problem for the rest, but it is also, as Ariela J. Gross writes in her densely researched "What Blood Won't Tell: A History of Race on Trial in America," a "moving target," whose definition and meaning is always in flux. Many of us can avoid encountering this strange truth in the imprecise realms of cultural and social life, but when it comes to the law, imprecision just doesn't cut it. Gross' book, a history of cases in which people have challenged their official racial designation, eloquently demonstrates just how difficult it can be to say what race -- mine, yours, anybody's -- actually consists of.
