'In a moving, disturbing series of messages, some of the world's smartest and best informed political analysts reflect on the causes, meanings, and consequences of September 11, 2001. Except for challenging the idea of two well defined worlds - one good, one bad - at war, the authors disagree widely. Taken together, however, their essays issue an eloquent call for broader, deeper, more humane responses to today's political crises, and lay out many possible elements of those responses.' - Charles Tilly, Joseph L. Buttenwieser Professor of Social Science, Columbia University
