Even the most complex models used in fishery management are cartoons of reality. They reduce hundreds of links in food webs to a handful and inadequately represent processes operating over space. Many of their assumptions are as flawed today as those of the simplest models of the past. Fish stocks, for one. are still assumed to be populations of a species that are isolated from one another. Yet many populations mix at their edges and some even migrate through areas occupied by other populations. Furthermore, the more complex models suffer from a "crisis of complexity"—more is really less. Adding layers of detail, each carrying its own set of assumptions, produces instability. The model's behavior becomes erratic, and conclusions drawn from it can be downright misleading.

Part of the reason may stem from frustrations involved with reading poems that are so highly topical—often requiring, even as a condition of first-level comprehension, a familiarity with names and references that, while wholly recognizable in their own time, are obscure to modem readers. Yet beyond this is the fact that American political verse from the eighteenth and early nineteenth centuries has never fully shaken off the verdict, delivered by its earliest generation of scholarly readers. that it is simply unworthy of serious attention as literature. Even the term commonly used to describe it—"verse." as opposed to "poetry"— suggests an occasional or forgettable, rather than enduring, form of expression, not quite deserving the designation of poetry. Nor was such verse considered by early critics as worthy of the designation "American." as the tendency of eighteenth-century American poets to model their works on those of British precursors suggested an unforgivable failure, as one critic described it. to declare their "literary independence" from Britain.
