Because I have been thinking and writing about liberal education for many years, I have more thanks to give than I can properly record here. The many schools, colleges, and universities that have debated the conclusions of my earlier book, Cultivating Humanity, must be at the top of the list, as must the Association of American Colleges and Universities, whose members and leaders have been an invaluable source of inspiration and insight. I want to thank Carole Schneider, president of that Association, for involving me in her LEAP report on higher education, and for generously reacting to some of these ideas when I presented them in an earlier form. Mike McPherson of the Spencer Foundation has also been a terrific source of insight, and the year I spent as a resident fellow at the Foundation taught me a lot about this topic, although at the time I was working on a different project. My ongoing association with the Cambridge School in Weston, Massachusetts, where my daughter was educated, gives me optimism about the future of the type of education I defend here. Jane Moulding, the school's head, and all the faculty and trustees are to be honored for their commitment to critical thinking and the arts in an era in which those commitments go against the grain. In a very different way, I get support and nourishment every day from my colleagues at the University of Chicago Law School, an unusual intellectual community where interdisciplinary critical thinking thrives.
