In any edited volume most credit is due to the individual authors. The present case is no exception and we as editors have done little apart from serving as coordinators for a group of friends and colleagues. For once, the responsi- bilities are shared. We feel that the collection gives a fair representation of the activities at the frontier of human geography in North America. Whether these premonitions will be further substantiated is of course to be seen. In the meantime, we take refuge in Vico's saying that "doctrines must take their beginning from that of the matter of which they treat." And yet we also know that new treatments never lead to fmal ends, but rather to new doctrines and to new beginnings.
