In his August 1 Breakpoint commentary, Charles Colson said, "Last year, Zogby International took a poll of American college seniors in which 97 percent said that they believed their professors had given them a good education in ethics. But when asked what those professors had taught them, 73 percent responded, "What is right and wrong depends on differences in individual values and cultural diversity." Only a quarter of them said they had learned that there are "clear and uniform standards of right and wrong." Similarly, a reporter for Forbes magazine observed an ethics class at Harvard Business School in which the professor and students discussed case studies but avoided coming to any moral conclusions. Students were graded on how well they could logically defend their position, not on whether their position was actually defensible. The reporter wrote that students in this kind of class, rather than developing moral principles, merely "develop skills enabling them to rationalize anything short of cannibalism."
