Amartya Sen has a piece on Slate talking about the limitations of Huntington's "Clash of Civilizations" thesis. In fact, it's an essay drawn from his new book on the same subject. An excerpt:
"The difficulty with the clash of civilizations thesis begins with the presumption of the unique relevance of a singular classification. Indeed, the question "Do civilizations clash?" is founded on the presumption that humanity can be pre-eminently classified into distinct and discrete civilizations, and that the relations between different human beings can somehow be seen, without serious loss of understanding, in terms of relations between different civilizations.
This reductionist view is typically combined, I am afraid, with a rather foggy perception of world history that overlooks, first, the extent of internal diversities within these civilizational categories, and second, the reach and influence of interactions—intellectual as well as material—that go right across the regional borders of so-called civilizations. And its power to befuddle can trap not only those who would like to support the thesis of a clash (varying from Western chauvinists to Islamic fundamentalists), but also those who would like to dispute it and yet try to respond within the straitjacket of its prespecified terms of reference."
Also from the piece:
"The insistence, if only implicitly, on a choiceless singularity of human identity not only diminishes us all, it also makes the world much more flammable. The alternative to the divisiveness of one pre-eminent categorization is not any unreal claim that we are all much the same. Rather, the main hope of harmony in our troubled world lies in the plurality of our identities, which cut across each other and work against sharp divisions around one single hardened line of vehement division that allegedly cannot be resisted. Our shared humanity gets savagely challenged when our differences are narrowed into one devised system of uniquely powerful categorization.
Perhaps the worst impairment comes from the neglect—and denial—of the roles of reasoning and choice, which follow from the recognition of our plural identities. The illusion of unique identity is much more divisive than the universe of plural and diverse classifications that characterize the world in which we actually live. The descriptive weakness of choiceless singularity has the effect of momentously impoverishing the power and reach of our social and political reasoning. The illusion of destiny exacts a remarkably heavy price."
