Flipping through an old grammar, I was surprised to find that the following is a common construction in English:
It is + adjective + that + ... should ... (use: forming judgment)
E.g. It is natural that he should think so.
It is nice that you should attend his meeting.
what actually does 'should' mean here? I come across quite a lot of 'should's' like these in Jane Austen's masterpieces, hence inclined to regard these as rather formal, old-fashioned English. What do you think?
Yes, it's rather formal and old-fashioned.
