The Brilliance of Steven Pinker's Mind

Cosmologists, Quantum Physicists, Geneticists, Cognitive Scientists, Evolutionary Biologists and others are continuously working to advance human understanding from the macro (origins of the universe) to the micro (behavior of genes, functioning of the mind). All this knowledge has a profound influence on metaphysics, religion, ethics, economics, sociology and other fields of the humanities and social sciences. These areas of human study then have to contend with the onrush of scientific evidence about human behavior, its nature and its origins either by incorporating the evidence or by challenging it. It is therefore of the utmost importance that laypeople who care about these issues develop some understanding of the current state of scientific learning about these subjects.

In the modern world where experts know "more and more about less and less" the effort of many brilliant practitioners in highly specialized fields to engage laypeople with their complex ideas is worthy of great praise. To make these ideas digestible without dumbing them down requires not only an exceptional clarity of mind but great expositional skills. Fortunately there are many accomplished scientists who also possess a rare ability to educate the non-specialist. Richard Dawkins, E.O. Wilson, Ernst Mayr, Stephen Jay Gould, Carl Sagan, Paul Davies, Brian Greene and Richard Feynman are some of the examples of scientists who have succeeded to varying degrees in reaching beyond their rarefied peer group.

Steven Pinker, the hard to label Harvard Evolutionary Psycholgist is amongst one of the best examples of current scientists who can write well for a broader audience. This post was precipitated after reading his excellent essay titled "The Moral Instinct" in the January 13th, 2008 issue of The New York Times Sunday Magazine. It is hard to summarize the breadth of the essay's argument but in it Pinker explains the existing evidence for the biological (evolutionary) underpinnings of our morality. He examines many interesting examples about the universality of morals and tries to square them with the clearly observed differences across cultures. The essay is somewhat long but I couldn't recommend it any more strongly and urge people to read it. There are few popular pieces of writing that engage this deeply in reflecting on the sources of our deeply held moral beliefs.

Excerpts:

When anthropologists like Richard Shweder and Alan Fiske survey moral concerns across the globe, they find that a few themes keep popping up from amid the diversity. People everywhere, at least in some circumstances and with certain other folks in mind, think it’s bad to harm others and good to help them. They have a sense of fairness: that one should reciprocate favors, reward benefactors and punish cheaters. They value loyalty to a group, sharing and solidarity among its members and conformity to its norms. They believe that it is right to defer to legitimate authorities and to respect people with high status. And they exalt purity, cleanliness and sanctity while loathing defilement, contamination and carnality.
The exact number of themes depends on whether you’re a lumper or a splitter, but Haidt counts five — harm, fairness, community (or group loyalty), authority and purity — and suggests that they are the primary colors of our moral sense. Not only do they keep reappearing in cross-cultural surveys, but each one tugs on the moral intuitions of people in our own culture.

All this brings us to a theory of how the moral sense can be universal and variable at the same time. The five moral spheres are universal, a legacy of evolution. But how they are ranked in importance, and which is brought in to moralize which area of social life — sex, government, commerce, religion, diet and so on — depends on the culture. Many of the flabbergasting practices in faraway places become more intelligible when you recognize that the same moralizing impulse that Western elites channel toward violations of harm and fairness (our moral obsessions) is channeled elsewhere to violations in the other spheres. Think of the Japanese fear of nonconformity (community), the holy ablutions and dietary restrictions of Hindus and Orthodox Jews (purity), the outrage at insulting the Prophet among Muslims (authority). In the West, we believe that in business and government, fairness should trump community and try to root out nepotism and cronyism. In other parts of the world this is incomprehensible — what heartless creep would favor a perfect stranger over his own brother?
