Troubled times breed reflective thinkers. As inhabitants of such an era we join those from other ages, other disciplines and even other civilizations in the search for historical understanding. We try to make sense of the world we live in, in order to distinguish what we can change and what we cannot, to illuminate the choices we may make, to inspire informed hope and counsel reasoned caution in our descendants, giving dignity to our own brief lives, our contemporaries and those before and after us.

As a teacher of an historically oriented interdisciplinary course on theories of international relations, I am struck both by the centrality of these purposes in the literature I have recently assigned to my students, and the unsatisfactory nature of the interpretive accounts they provide. Among scholarly studies of our multifaceted predicament written in the last decade or so, perhaps the most attention catching have been:

• ~~(a) the global modeling studies evoked by the Club of Rome's amplification of debates occasioned by Jay Forrester's World Dynamics; and

• ~~(b) the Annales style of modern world systems studies stimulated by Fernand Braudel's exemplary writings, starting with La Méditerranée à l'poque de Philippe II.
