If we really want to find the truth, we need viewpoint diversity. It is as important as biodiversity and basically for the same reason. Cross fertilization breeds strength. As John Stuart Mill, the great philosopher of liberalism, said,

“He who knows only one side of the case knows little of that.  His reasons may be good and no one may have been able to refute the reasons on the opposite side, if he does not so much as know what they are, he has no good ground for preferring either opinion.”

Such an attitude automatically respects that others may have some truth. We may have something to learn from others. As a result, such an attitude automatically leads us away from extremism.  We then can’t just shout hooray for our side.

Mill makes the point that if you have no viewpoint diversity and listen only to one side, and as a result your ideas are not exposed to challenge, you get stupid! You get intellectually lazy and you just believe dogmatically and then, if you are pushed to explain your viewpoint or defend it, you can’t.

Mill says you should listen to the other side because you might be wrong and because the other side might be right. If you are wrong and you listen to another viewpoint your error might be exposed and then you might avoid making a mistake. That is good!  Similarly, if you are right and yet you listen to another opinion you learn how to defend your opinion and strengthen it. Your opinion will be more solid, more defendable. That is good too! Such humility is also the basis of syncretism and pluralisms, two of my favourite things.

Will Braun is a person who enjoys talking with the other side, because he is curious about them, but also because he realizes he might actually learn something from them that he did not know before.

Braun, like me, lives in a very conservative area of Manitoba.  When Justin Trudeau was first elected, he said we must remember, “Conservatives are not our enemies; conservatives are our neighbours.” In nearly every debate of substance we must remember, the other side is not our enemies, they are fellow travelers. In Steinbach it is literally true. The conservatives are my neighbours not my enemies. Sometimes I forget that. When I do forget, I am wrong. My bad. Maybe Trudeau forgot that later too. It is easy to forget these wise words. We all do it.

Remembering we might be wrong can temper the extremes. That is another good reason to have doubts. Doubts are good.
