I’m very familiar with Huntington’s CoC theory, and by and large I agree with it. Obviously, it’s easy to see this played out all over the world. But even here in the west, we are seeing deep cultural and religious rifts threatening to pull nations apart like we haven’t seen before. (I dont want to be unfairly cynical though, there are also many integrative forces at work globally, and there is a lot of evidence that they’re working. i.e reduction in poverty, drop in armed conflict, ever increasing number of IGOs, etc)
But I don’t think that it enables racism. The theory is a prediction based on observation, not an instruction manual. It doesn’t tell (or even inspire) people or nation-states to behave cruelly. And don’t worry, it’s over 2 decades old, so any sort of knee jerk policy created in response to this would have come and gone already.
I would highly doubt that the church has made a statement about this. It isn’t a moral teaching or idea, it’s just an observation. The church would have to disagree with the observation and come up with a new prediction. And as much as I would love to hear the Pope’s predictions about the future of foreign affairs and global governance, I’m just not sure that’s the best use of his time right now.
I lecture political theory and I keep trying to work this in, but there’s really no way. It’s more appropriate for an international relations course. But I’m really into discussing things like this, so if you ever stumble across something that you want to talk about or even fiercely debate, feel free to send me a PM.
