The response to the Daily Stoic emails can be a fascinating peek into human psychology. One email, because it makes a fairly objective point about Donald Trump’s temperament, produces a record number of unsubscribes. Another, because it mentions Winston Churchill without condemning British imperialism, gets all sorts of angry comments on Facebook. We are alternatively criticized for being too liberal and too conservative, often on successive days and sometimes for the very same email.It’s not just remarkable the way that some well-intended Stoic practitioners get really upset when their views or political opinions are challenged, but it offers an unsparing look at the dimensions of the filter bubble in which we live and don’t even notice. We take for granted how often our beliefs are confirmed or implicitly validated by the information we consume and the company we keep. Yet, the second the walls of that bubble are breached by something or someone that appears to disagree with our worldview, we act like victims of some profound personal violation. We rear up like a bull that’s had a big red flag waved tauntingly in front of us. We just have to charge it.In Meditations, Marcus Aurelius talks about practicing with his non-dominant hand so that he can get better (and be more balanced). We should do the same with viewpoints we disagree with. Instead of being upset when someone makes a point we don’t like today, try to really listen. Don’t think about all the ways they are wrong, take a moment to think about where they think you are wrong. Assume good faith on behalf of the person on the other side of the issue in question and engage. And if they are not arguing in good faith? Even better--use that as an opportunity to be patient with them. See if you can hold your temper and just let them do what they do, without it ruining your day. This is not only how we get stronger and better as people, but it’s also how civil society is supposed to work. Debate and disagreement are good. Diversity of opinion is good. If you let it bother you, you will never be at peace and, paradoxically, actual peace will be less achievable as well.
