Scientific case for utilitarianism

“The philosopher and cognitive neuroscientist Joshua Greene has argued that many deontological convictions are rooted in primitive intuitions of tribalism, purity, revulsion, and social norms, whereas utilitarian conclusions emerge from rational cogitation.20 (He has even shown that the two kinds of moral thinking engage emotional and rational systems of the brain, respectively.)” (Steven Pinker, Enlightenment Now)
