Supreme Court Justice Oliver Wendell Holmes said there were “phrases that serve as an excuse for not thinking.” One of these phrases that substitute for thought today is one that depicts the current problems of blacks in America as “a legacy of slavery.”

New York Times writer Nicholas Kristof asserts that there is “overwhelming evidence that centuries of racial subjugation still shape inequity in the 21st century” and he mentions “the lingering effects of slavery.” But before we become overwhelmed, that evidence should be checked out.
