What I find especially interesting is why we think that these metaphysical concepts make sense. We do not only seem to think 'it makes sense', there seems to be an actual _emotion_ connected to it. We like it!

I mean, we look at evolution and at some point it 'just clicks', we wrap our head around it and see the abstraction clearly everywhere. And we like that we understand.

But we do we like it? Why do we like the explanation?

It also works the other way around: For example, look at the concept of the infinite regress. When one comes up, we actually seem to dislike the ideas that lead to it. Emotionally. There is no logical/rational reason for the dislike. Why so?
