What does Harvard president Larry Summers’ resignation mean? “Some look at him and see a textbook example of why trustees need to pay attention to what professors think. Others think he’s a textbook example that faculty members have too much say in what goes on at their campuses. Some think his biggest legacy in higher education will be unprecedented national discussion of women in science — an issue on which he didn’t intend to set off a public debate. Others think the collapse of his presidency may scare boards from hiring presidents who want to speak out on any controversial issues.”
