-- Abraham Lincoln
WASHINGTON -- With Americans shocked into reflection on the desperate, divisive tone of their politics, it is worth asking: Why, other than upbringing, should we be civil in the first place?
In the Western tradition, one answer has been rooted in epistemology -- the limits of knowledge. Citizens, in this view, should not be arrogant or intolerant about their political, moral and religious views because no one has the right to be certain of his or her views. What our public life needs is more ambiguity, agnosticism and detachment. The humble are less strident, more peaceful.
This argument is made by a certain kind of campus relativist, who views the purpose of education as the systematic cultivation of doubt. But it is also reflected in the conservative tradition, which is suspicious of ideological certainties that lead to radical social experiments. Both the liberal and conservative variants of this epistemological modesty can be traced back to classical liberal thinkers such as John Locke, whose overriding concern was to prevent wars of opinion, particularly religious wars. If no one believed their opinions were absolutely true, there would be less incentive to attack or coerce others. In the absence of harmful certainty, society would operate by barter and compromise.
But there is a second, very different argument for civility -- this one rooted in anthropology. The Christian and natural law traditions assert that human beings are equal and valuable, not because of what they think but because of who they are. Even when badly mistaken, their dignity requires respect for their freedom and conscience. A society becomes more just and civil as more people are converted to this moral belief in human dignity and reflect that conviction in their lives and laws.
Without a doubt, doubt is useful and needed at the margins of any ideology. The world is too complex to know completely. Many of our judgments are, by nature, provisional. Those who are immune to evidence, who claim infallibility on debatable matters, are known as bores -- or maybe columnists.
Yet doubt becomes destructive as it reaches the center of a belief and becomes its substitute. A systematic skepticism may keep us from bothering our neighbor. It does not motivate a passion to fight for his or her dignity and rights. How do ambiguity and agnosticism result in dreams of justice, in altruism and honor, in sacrifices for the common good? What great reformers of American history can be explained by their elegant ambivalence?
The holiday just past demonstrates the limits of a political philosophy founded on doubt. Martin Luther King Jr. did not oppose segregation because its supporters were too doctrinaire. He opposed segregation because it was an insult to the nature of human beings. He did not seek to lessen passions by exposing ambiguity. He sought to persuade Americans of a superior moral belief -- to convert them to the ideals of their own founding. The intensity of his convictions led him to be a firebrand, a leader, a martyr. Yet he argued for peaceful, civil methods because even oppressors had dignity and value, and thus the hope of redemption.
Moral conviction is not a synonym for arrogance. Both of the paths to civility call for humility. A civility based on doubt demands an appreciation for our own ignorance. A civility grounded in human dignity requires us to bow before a principle greater than ourselves -- the belief that others count and matter as much as ourselves. The latter is more difficult to cultivate, but more lasting and important.
So what is the source of America's current civility problem? Is there too much immodest conviction? Or is there too little regard for the value and dignity of others?
There is no reason that both answers can't be "yes." But the second challenge is primary. We need a robust civility that allows for deep and honest disagreements instead of explaining those differences away. In the long run, this is only achievable if Americans believe that their fellow citizens deserve respect, even when they hold absurd political beliefs.
It is not a coincidence that the first draft of the American ideal begins with a statement of anthropology, asserted without epistemological modesty. "We hold these truths to be self-evident, that all men are created equal." It is this belief -- not the absence of belief -- that provides the most compelling reason for civility. We are not enemies, but friends.
