—G. K. Chesterton
In a great irony, the "politically correct" movement defending the rights of women, minorities, and the environment often positions itself as an enemy of the Christian church when, in historical fact, the church has contributed the very underpinnings that make such a movement possible. Christianity brought an end to slavery, and its crusading fervor also fueled the early labor movement, women's suffrage, human-rights campaigns, and civil rights. According to Robert Bellah, "there has not been a major issue in the history of the United States on which religious bodies did not speak out, publicly and vociferously."
It was no accident that Christians pioneered in the antislavery movement, for their beliefs had a theological impetus. Both slavery and the oppression of women were based, anachronistically, on an embryonic form of Darwinism. Aristotle had observed that
Tame animals are naturally better than wild animals, yet for all tame animals there is an advantage in being under human control, as this secures their survival. And as regards the relationship between male and female, the former is naturally superior, the latter inferior, the former rules and the latter is subject. By analogy, the same must necessarily apply to mankind as a whole. Therefore all men who differ from one another by as much as the soul differs from the body or man from a wild beast (and that is the state of those who work by using their bodies, and for whom that is the best they can do)—these people are slaves by nature, and it is better for them to be subject to this kind of control, as it is better for the other creatures I have mentioned . …It is clear that there are certain people who are free and certain people who are slaves by nature, and it is both to their advantage, and just, for them to be slaves. … From the hour of their birth, some men are marked out for subjection, others for rule.
Cross out the name Aristotle and read the paragraph again as the discovery of a leading evolutionary psychologist. No one is proposing the reimposition of slavery, of course—but why not? If we learn our morality from nature, and if our only rights are those we create for ourselves, why should not the strong exercise their "natural rights" over the weak?
As Alasdair MacIntyre remarks in After Virtue, modern protesters have not abandoned moral argument, though they have abandoned any coherent platform from which to make a moral argument. They keep using moral terminology—it is wrong to own slaves, rape a woman, abuse a child, despoil the environment, discriminate against homosexuals—but they have no "higher authority" to which to appeal to make their moral judgments. MacIntyre concludes,
Hence the utterance of protest is characteristically addressed to those who already share the protestors' premises. The effects of incommensurability ensure that protestors rarely have anyone else to talk to but themselves. This is not to say that protest cannot be effective; it is to say that it cannot be rationally effective and that its dominant modes of expression give evidence of a certain perhaps unconscious awareness of this.
In the United States, we prefer to settle major issues on utilitarian or pragmatic grounds. But philosophers including Aristotle and David Hume argued powerfully in favor of slavery on those very grounds. Hitler pursued his genocidal policies against the Jews and "defective" persons on utilitarian grounds. Unless modern thinkers can locate a source of moral authority somewhere else than in the collective sentiments of human beings, we will always be vulnerable to dangerous swings of moral consensus.
