As I observe all of the angry discourse in our society today, I am left with a sense that we are much too certain of ourselves.

If the other side is wrong, we are certain that then we must be right, even though in most cases that is not necessarily so.

We are certain that we know causation, when all that has been demonstrated is correlation.

In the domains of definite uncertainty, where neither God nor science has spoken, we are nonetheless certain that our opinion is ultimately right.

I do believe that some things we can be certain of, and should be certain of, and should live with passionate conviction to those certainties. But I think that those are only a few, core things, and we should be nuanced enough to call all the rest a hunch, a belief, and an assumption.
