“Most right-thinking, well-educated, and well-intentioned people — certainly most scientists and public intellectuals, and I would guess, most journalists — have been convinced that something in the last 200 years of intellectual progress has made it impossible to actually speak about “moral truth.” Not because human experience is so difficult to study or the brain too complex, but because there is thought to be no intellectual basis from which to say that anyone is ever right or wrong about questions of good and evil. . .
“The first thing I should point out is that, apart from being untrue, this view has consequences.
In 1947, when the United Nations was attempting to formulate a universal declaration of human rights, the American Anthropological Association stepped forward and said, it can’t be done. This would be to merely foist one provincial notion of human rights on the rest of humanity. Any notion of human rights is the product of culture, and declaring a universal conception of human rights is an intellectually illegitimate thing to do. This was the best our social sciences could do with the crematory of Auschwitz still smoking.
But, of course, it has long been obvious that we need to converge, as a global civilization, in our beliefs about how we should treat one another. For this, we need some universal conception of right and wrong. So in addition to just not being true, I think skepticism about moral truth actually has consequences that we really should worry about.”
