He assumes that he can know the scientific view of someone based on their party affiliation. He’s not rational, or he’s making a big joke of the subject. So why should anyone care about his careless remarks?
Actually he is responding to the conclusions of Haidt in his article for Edge called WHAT MAKES PEOPLE VOTE REPUBLICAN? and using the terms liberal and conservative the way that Haidt uses them for the sake of argument. While Harris promotes a view of morality concerned with human well-being, Haidt’s position is that morality is concerned with “binding groups together.” Haidt writes, “…the second rule of moral psychology is that morality is not just about how we treat each other (as most liberals think); it is also about binding groups together, supporting essential institutions, and living in a sanctified and noble way. When Republicans say that Democrats “just don’t get it,” this is the “it” to which they refer.”
I wouldn’t make too much of the politics of the essay. The issue I was hoping you’d focus on is whether science can study morals. Harris response is published on
Edge.org under the title, “Brain Science and Human Values,” where he makes the same case for a science of morals as he does in the Beyond Belief conference that I linked to previously. Try again to understand his argument without concerning yourself with politics. I’ve edited out the less relevent parts to our discussion:
Harris writes,
"…Belief encompasses two domains that have been traditionally divided in our discourse. We believe propositions about facts, and these acts of cognition subsume almost every effort we make to get at the truth—in science, history, journalism, etc. But we also form beliefs about values: judgments about morality, meaning, personal goals, and life’s larger purpose. While they differ in certain respects, these types of belief share some important features.
Both types of belief make tacit claims about normativity: claims not merely about how we human beings think and behave, but about how we should think and behave. Factual beliefs like “water is two parts hydrogen and one part oxygen” and ethical beliefs like “cruelty is wrong” are not expressions of mere preference. To really believe a proposition (whether about facts or values) is also to believe that one has accepted it for legitimate reasons. It is, therefore, to believe that one is in compliance with a variety of norms (i.e., that one is sane, rational, not lying to oneself, not overly biased, etc.) When we really believe that something is factually true or morally good, we also believe that another person, similarly placed, should share our conviction.
Despite the remonstrations of people like Jonathan Haidt and Richard Shweder, science has long been in the values business. Scientific validity is not the result of scientists abstaining from making value judgments; it is the result of scientists making their best effort to value principles of reasoning that reliably link their beliefs to reality, through valid chains of evidence and argument. The answer to the question, “What should I believe, and why should I believe it?” is generally a scientific one: Believe a proposition because it is well supported by theory and evidence; believe it because it has been experimentally verified; believe it because a generation of smart people have tried their best to falsify it and failed; believe it because it is true (or seems so). This is a norm of cognition as well as the epistemic core of any scientific mission statement.
But what about meaning and morality? Here we appear to move from questions of truth—which have long been in the domain of science if they are to be found anywhere—to questions of goodness. How should we live? Is it wrong to lie? If so, why and in what sense? Which personal habits, uses of attention, modes of discourse, social institutions, economic systems, governments, etc. are most conducive to human well-being?
…
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.
Unless human well-being is perfectly random, or equally compatible with any events in the world or state of the brain, there will be scientific truths to be known about it. These truths will, inevitably, force us to draw clear distinctions between ways of thinking and living, judging some to better or worse, more or less true to the facts, and more or less moral.
…
If there are objective truths about human well-being—if kindness, for instance, is generally more conducive to happiness than cruelty is—then there seems little doubt that science will one day be able to make strong and precise claims about which of our behaviors and uses of attention are morally good, which are neutral, and which are bad."
