In the second half of the twentieth century, a surprising change in the notion of scientific truth gained ground when an evolutionary cosmology made the Newtonian world machine into no more than a passing phase of the cosmos, subject to exceptions in the neighborhood of Black Holes and other unusual objects. Physical and chemical laws ceased to be eternal and universal and became local and changeable, that is, fundamentally historical instead, and faced an uncertain, changeable future just as they had (...) in the initial phases of the cosmos.The earth sciences along with biology had become historical in the nineteenth century; and the Big Bang cosmology in effect brought physics and chemistry into line, allowing venturesome intellects to concoct a new all-embracing worldview that recognizes the catalytic role of the observer in defining what is observed, and how different levels of local complexity provoke new and surprising phenomena--including terrestrial life forms, and most notably for us, humanly-constructed symbolic meanings--of which science is only one example.The article then argues that it is time for historians to take note of the imperial role thus thrust upon their discipline by making a sustained effort to enlarge their views and explore the career of humankind on earth as a whole, thus making human history an integral part of the emerging scientific and evolutionary worldview.Tentative suggestions of how this might be addressed, focusing on changes in patterns of communication that expanded the scale of human cooperation, and thus conduced to survival, follow. Dance, then speech, were early breakthroughs expanding the practicable size of wandering human bands; then caravans and shipping allowed civilizations to arise; writing expanded the scale of coordination; warfare and trade harshly imposed best practice across wide areas of Eurasia and Africa and kept the skills of that part of the world ahead of what the peoples of other continents and islands had at their command. Then with the crossing of the oceans after 1492 our One World began to emerge and swiftly assumed its contemporary shape with further improvements in the range and capacity of communication--for example, printing, mechanically-powered transport, instantaneous data transmission--with consequences for human society and earth's ecosystem yet to be experienced.Much remains to be investigated and, in particular, interactions between the history of human symbolic meanings and the history of other equilibria--ecological, chemical, physical--within which we exist needs further study. But with suitable effort, history can perhaps become scientific and the emerging scientific evolutionary worldview begin to achieve logical completeness by bringing humankind within its scope.

After surveying the development of world-historical views from Herodotus and Ssu-ma Chen to Spengler and Toynbee, the author sketches his own current understanding of the best approach to the subject. The organizing concept is hard to name, being the geographically largest circle of effective interaction among peoples of diverse cultures and circumstances. In recent times interaction has become literally world-wide; but before 1500 several different communications nets co-existed, each with a dynamic of its own, though the largest was always situated (...) in Eurasia and now embraces the globe.Competing terms exist: "interactive zone," "world system," and "ecumene," but none is completely satisfactory or generally accepted by world historians. Nonetheless, the author asserts that a perceptible drift towards recognizing the reality and centrality of this large structure in the human past has begun to show up among practicing world historians; and the balance of the essay sketches how key alterations in patterns of Eurasian communication mark the principal stages in the expansion and intensification of interaction within the Eurasian ecumene.

Worldviews affect human behavior, and how we behave affects the world around us. Animism and so-called higher religions remain influential world-views; but the scientific worldview is comparably significant, and has under-gone drastic change during the twentieth century. The physical science ideal of mathematical precision and predictability, as elaborated by Galileo, Newton, and their heirs, underwent an amazing transformation in the twentieth century when Big Bang cosmology substituted an expanding, unstable universe for the Newtonian world machine. As a result, a grand (...) convergence of the sciences seems to be emerging around an evolutionary vision of how new aspects of reality emerge locally from new levels of complexity, like the heavier atoms, forged in stellar furnaces, the living molecules that arose in earth's primordial seas, and the symbolic systems invented by human societies perhaps as recently as forty thousand years ago. History, once a hopelessly inexact laggard among the sciences, might even become something of a model for other disciplines, since it deals with the most complex levels of reality we are aware of, that is, the world of agreed-upon meanings that guides our interaction with one another and with the biological, chemical, and physical worlds around us.
