Sam Harris makes some interesting arguments for why science should be involved in evaluating moral arguments in his recent TED Talk. He argues that there is often not one “correct” position to take on an issue, but a range of position, some better, some worse than others, and that science can help us figure out which help people live more fulfilled lives.
For example, in looking at how societies portray the model of womanhood, there are probably a number of morally positive ways to do this in between the extremes of the Islamic Burka, and the overt sexuality on the covers of many western mens magazines.
Harris also addresses the issue of giving the same weight to all moral arguments, irregardless of their source. He argues that some people are better at moral thinking that others, just like some people are better a physics than others, so why should we put the Dali Lama and Ted Bundy on the same footing when it comes to looking at moral arguments?
A thought provoking video even if you don’t agree with everything he says.
