The problem is that it can't be objectively shown 'what is good for humans.'
It is quite remarkable how difficult it can be to get people to concede that human well-being is what should concern us. For example, the Roman Catholic Church is more concerned about preventing contraception than about preventing the rape of children. So, if we are concerned about human well-being, we have what Sam Harris calls an inversion of priorities. But, to the point, I think that we can say that the molestation and torture of children is not good for humans and that a sense of achievement and fulfillment in the lives of humans is good. There are a whole lot of find gradations between these two extremes which are currently beyond objective measurement.
I don't think that we have any obligation to take seriously the moral dictates of those who clearly are not objectively concerned with human well-being, anymore than we need to take seriously the opinions with regard to biology or physics of those who are not concerned with the facts and evidence relevant to those fields.
We have years of research in neurology, sociology and psychology. We have made very impressive gains in societies' treatment of women. Now suppose that some people think that forcing half the population to live in cloth bags, and beating them or killing them when they try to get out, is as good as anything we've come up with. We know enough about human well-being right now to declare based on neurology, sociology and psychology that this is not good;
good as defined by all the factors included in human well-being.
And there many scientific truths that we will never be able to test because we cannot get the data. For example, how many birds are in flight over the surface of the Earth at this moment? We have no idea, and it just changed. And yet that is a very simple question about the nature of reality, which we know has an answer. We know that questions of human well-being do have answers. Some of the answers may well be difficult or even impossible to find. However, throwing battery acid in the face of a little girl, for the crime of learning to read, is clearly not a mode of sanely pursuing human welfare.
Human well-being is not a random phenomenon. It depends on many factors including genetics, neurology, sociology and economics. There are scientific truths to be known about how we can achieve human well-being. I really believe that we must start to use the sciences to discover those truths and stop relying on tradition, culture and divine revelation that deflect us from getting valid answers.
