In a recent interview on the Barnes & Noble Review website promoting his latest book, historian Jared Diamond mentions how treatment of the young "varies among traditional societies just as it varies among industrial societies," and gives examples of how some of the former use corporal punishment for discipline purposes while others "consider it utterly unacceptable to hit a child." Such violence, Diamond points out, is culturally determined, and when prompted he says that he has never struck his own children. "It is not a good idea," he says. "I see a lot of harm to hitting a child."
