Guardian | We live in an age intolerant of doubt. Communicating uncertainty is well nigh impossible across fields as diverse as politics, religion and science. There's a fear of doubt abroad too. It's most palpable, at the moment, whenever there's news of economic uncertainty. Waves of nervousness ripple through financial markets and supermarkets alike. And yet, at the same time, few would deny that only the fool believes the future is certain. And who doesn't fear that most shadowy figure of our times, the fundamentalist – with their deadly, steadfast convictions?The confusion is understandable. Doubt is unsettling. It's not for nothing that old maps inscribed terra incognita with the words "here be dragons". Further, the tremendous success of science, and the transformation of our lives by technology, screens us from many of the troubling uncertainties that our ancestors must have been so practised in handling.
But are we losing what might be called the art of doubt too? For, in truth, without doubt there is no exploration, no creativity, no deepening of our humanity – which is why the individual who claims to know something beyond all doubt is a person to shun, not emulate. Stick to what you know and you'll find some security, but you'll also find yourself stuck in a rut. Learn to welcome the unknown, to embrace its thrill, and new worlds might open up before you.
