There is growing agreement among scholars and citizens that our planet and its peoples are presently living through an era of great political uncertainty. Global pestilence, species destruction, shrinking US power and the birth of a new Chinese global empire are among the forces said to be responsible for the rising tides of uncertainty. Some observers even speak of a great leap backwards, a regression towards catastrophe, a rebirth of the disquiet and fear that marked the world of the 1920s (...) and 1930s. They are sure that the future will bring only threats, rather than new opportunities to live well. This essay notes the seriousness of things, but it raises doubts about these pessimistic claims of a new age of uncertainty. Historical comparisons are needed. So is greater clarity about the role played by communicative abundance in inflating our collective sense of doom. And a paradox is noted: calamities do more than stir up questions about how best to classify and measure the experience of uncertainty. Definitions of uncertainty also become uncertain. This should be unsurprising. Only institutions and everyday experiences unaffected by the flow of time could be defined and lived with any certainty. The insight not only has rich implications for the way we think about politics and democracy and its vulnerability to morbid backlashes and yearnings for demagogues. Doubt can generate fresh ideas and positive practical breakthroughs. Disquiet and incertitude are fickle characters, but they are also challengers of all forms of human arrogance, including the dogmatic conviction that our world is now headed for hell. (shrink)
