To add to this, it wasn’t just about looking good but the fact that, in later centuries, dueling scars most often came from academic fencing. So a dueling scar meant you went to university, and therefore a higher rung of society.

The only problem is that any answer can be followed up with “But why does x do/cause that?”, and any answer to that can in turn be followed by the same question.

People accept, the classical explanation, that mass attracts mass so gravity “makes sense”, but when it comes to magnets the explanation isn’t so natural-feeling so most want, or at least feel that there is, more of an explanation.

And when the only further explanation left is that it works that way because it does, people feel like the phenomena has gone unanswered.
