This thought occurred to me just last night:
There are some opinions I understand and agree with. They are based on arguments and presuppositions which make sense to me, and which seem to me reasonable and well supported.
There are some opinions I disagree with. The arguments in their favour seem to me lacking in some way, perhaps by being based on presuppositions which I do not share, or perhaps due to a failure in logical reasoning from those presuppositions.
There are some opinions I disagree with completely. The arguments in their favour are non-existent, or are based on presuppositions so completely alien to my mind that I simply cannot make sense of them, or follow a chain of logical reasoning which I cannot grasp.
It occurred to me last night that the middle set, the arguments which seem lacking, but not fundamentally unreasonable or utterly incomprehensible, is a quite likely to be a reasonably good proxy for how open-minded we are. (Compare Aristotle’s dictum that it is the mark of an educated mind to be able to entertain an idea without accepting it. What I’m saying is not quite the same thing, but it is a related concept.) It also occurred to me that, for me, the middle set of ideas is, actually, rather small. I find it quite hard to get my head around conservative politics; I find it very difficult to understand or communicate with people who are uninterested in scientific evidence for or against the types of medicine they advocate; and I often find religious concepts difficult to grasp (which last is especially odd, given that I was raised religious).
So, how worried should I be about that?
