According to Sam Harris
Much of humanity is clearly wrong about morality—just as much of humanity is wrong about physics, biology, history, and everything else worth understanding. If, as I believe, morality is a system of thinking about (and maximizing) the well being of conscious creatures like ourselves, many people’s moral concerns are frankly immoral.
Does forcing women and girls to wear burqas make a positive contribution to human well-being? Does it make happier boys and girls? More compassionate men? More confident and contented women? Does it make for better relationships between men and women, between boys and their mothers, or between girls and their fathers? I would bet my life that the answer to each of these questions is “no.” So, I think, would many scientists. And yet, most scientists have been trained to think that such judgments are mere expressions of cultural bias. Very few of us seem willing to admit that simple, moral truths increasingly fall within the purview of our scientific worldview. I am confident that this period of reticence will soon come to an end.
