To look is a territorial activity. It is to observe one thing after another within a bounded space-as though in time it can all be seen. Academic fields are such territories. Sometimes everything in a field finally does get looked at and defined-that is, placed in its proper location. Mechanics and rhetoric are such fields. Physics may prove to be. Biological mysteries fall away at an astonishing rate. It becomes increasingly difficult to find something new to look at.
