Many of my best friends think that some of my deeply held beliefs about important issues are obviously false or even nonsense. Sometimes, they tell me so to my face. How can we still be friends? Part of the answer is that these friends and I are philosophers, and philosophers learn how to deal with positions on the edge of sanity. In addition, I explain and give arguments for my claims, and they patiently listen and reply with arguments of their own against my – and for their – stances. By exchanging reasons in the form of arguments, we show each other respect and come to understand each other better.

Philosophers are weird, so this kind of civil disagreement still might seem impossible among ordinary folk. However, some stories give hope and show how to overcome high barriers.

One famous example involved Ann Atwater and C P Ellis in my home town of Durham, North Carolina; it is described in Osha Gray Davidson’s book The Best of Enemies (1996) and a forthcoming movie. Atwater was a single, poor, black parent who led Operation Breakthrough, which tried to improve local black neighbourhoods. Ellis was an equally poor but white parent who was proud to be Exalted Cyclops of the local Ku Klux Klan. They could not have started further apart. At first, Ellis brought a gun and henchmen to town meetings in black neighbourhoods. Atwater once lurched toward Ellis with a knife and had to be held back by her friends.

Despite their mutual hatred, when courts ordered Durham to integrate their public schools, Atwater and Ellis were pressured into co-chairing a charrette – a series of public discussions that lasted eight hours per day for 10 days in July 1971 – about how to implement integration. To plan their ordeal, they met and began by asking questions, answering with reasons, and listening to each other. Atwater asked Ellis why he opposed integration. He replied that mainly he wanted his children to get a good education, but integration would ruin their schools. Atwater was probably tempted to scream at him, call him a racist, and walk off in a huff. But she didn’t. Instead, she listened and said that she also wanted his children – as well as hers – to get a good education. Then Ellis asked Atwater why she worked so hard to improve housing for blacks. She replied that she wanted her friends to have better homes and better lives. He wanted the same for his friends.

When each listened to the other’s reasons, they realised that they shared the same basic values. Both loved their children and wanted decent lives for their communities. As Ellis later put it: ‘I used to think that Ann Atwater was the meanest black woman I’d ever seen in my life … But, you know, her and I got together one day for an hour or two and talked. And she is trying to help her people like I’m trying to help my people.’ After realising their common ground, they were able to work together to integrate Durham schools peacefully. In large part, they succeeded.

None of this happened quickly or easily. Their heated discussions lasted 10 long days in the charrette. They could not have afforded to leave their jobs for so long if their employers (including Duke University, where Ellis worked in maintenance) had not granted them time off with pay. They were also exceptional individuals who had strong incentives to work together as well as many personal virtues, including intelligence and patience. Still, such cases prove that sometimes sworn enemies can become close friends and can accomplish a great deal for their communities.

Why can’t liberals and conservatives do the same today? Admittedly, extremists on both sides of the current political scene often hide in their echo chambers and homogeneous neighbourhoods. They never listen to the other side. When they do venture out, the level of rhetoric on the internet is abysmal. Trolls resort to slogans, name-calling and jokes. When they do bother to give arguments, their arguments often simply justify what suits their feelings and signals tribal alliances.

The spread of bad arguments is undeniable but not inevitable. Rare but valuable examples such as Atwater and Ellis show us how we can use philosophical tools to reduce political polarisation.

The first step is to reach out. Philosophers go to conferences to find critics who can help them improve their theories. Similarly, Atwater and Ellis arranged meetings with each other in order to figure out how to work together in the charrette. All of us need to recognise the value of listening carefully and charitably to opponents. Then we need to go to the trouble of talking with those opponents, even if it means leaving our comfortable neighbourhoods or favourite websites.

Second, we need to ask questions. Since Socrates, philosophers have been known as much for their questions as for their answers. And if Atwater and Ellis had not asked each other questions, they never would have learned that what they both cared about the most was their children and alleviating the frustrations of poverty. By asking the right questions in the right way, we can often discover shared values or at least avoid misunderstanding opponents.

Third, we need to be patient. Philosophers teach courses for months on a single issue. Similarly, Atwater and Ellis spent 10 days in a public charrette before they finally came to understand and appreciate each other. They also welcomed other members of the community to talk as long as they wanted, just as good teachers include conflicting perspectives and bring all students into the conversation. Today, we need to slow down and fight the tendency to exclude competing views or to interrupt and retort with quick quips and slogans that demean opponents.

Fourth, we need to give arguments. Philosophers typically recognise that they owe reasons for their claims. Similarly, Atwater and Ellis did not simply announce their positions. They referred to the concrete needs of their children and their communities in order to explain why they held their positions. On controversial issues, neither side is obvious enough to escape demands for evidence and reasons, which are presented in the form of arguments.

None of these steps is easy or quick, but books and online courses on reasoning – especially in philosophy – are available to teach us how to appreciate and develop arguments. We can also learn through practice by reaching out, asking questions, being patient, and giving arguments in our everyday lives.

We still cannot reach everyone. Even the best arguments sometimes fall on deaf ears. But we should not generalise hastily to the conclusion that arguments always fail. Moderates are often open to reason on both sides. So are those all-too-rare exemplars who admit that they (like most of us) do not know which position to hold on complex moral and political issues.

Two lessons emerge. First, we should not give up on trying to reach extremists, such as Atwater and Ellis, despite how hard it is. Second, it is easier to reach moderates, so it usually makes sense to try reasoning with them first. Practising on more receptive audiences can help us improve our arguments as well as our skills in presenting arguments. These lessons will enable us to do our part to shrink the polarisation that stunts our societies and our lives.
