After all, the best reason to go to college rather than, say, a fine free-standing library (think of the savings, were information the only point!) is to live for a time not only among teachers but among master learners. What students often find most precious is exposure to the ways practiced scholars and thinkers approach what they don't know. College, after all, is not about the easy movement through ideas guided by benevolent masters. It's about the harder stuff.
