A model of arc development, with doubts and questions: an editorial offering

Abstract

This slight offering, in part both speculative and provocative, is also my reward for much agonized editing, or at least it will be if my fellow contributors in particular, or readers in general, enter into discussion and argument on the doubts and questions offered at the end. It is a set of editorial musings, a modified version of part of an earlier preview on island arcs together with a newly conceived cartoon which featured as a lantern slide during the proceedings of our workshop/seminar.
