Once facts and reason were held up as essential if we were to make progress and create a better world. Now it seems everyone has their own 'facts'. Trump and Putin have their 'alternative' facts, but so also it is claimed does the liberal elite and the mainstream media. Meanwhile reason is derided by many as a typically male bludgeon to deny alternative views.
Should we welcome the shift from facts and reason as a progressive move undermining the authority of traditional Western hierarchies founded on establishment prejudice? Or is the undermining of facts and reason singularly dangerous - threatening a belligerent world with no shared framework and no communication?
