(Batman) Why can't the world's greatest detective figure out the jokers identity?

Surely it can't be that hard? Unless the Joker is smarter than Batman which I doubt.

Why bother? The Joker doesn't have a consistent alter ego the way Bats does. It's not like he spends his weekends as the mild-mannered John Jokerberg; he's Joker 24-7. So even if Batman did go to the trouble of finding out the name of the person Joker used to be, that's all it would be... A name. There's nothing to learn from it. Joker is Joker.
