That quote about hating Erdos is interesting. I think my professor for UCLA undergraduate honors seminar from years ago, hated Erdos (he at least express dislike for a colleague of Erdos who operated similar). My impression is Erdos appeared to operated as something like a whirlwind of chaotic fact and theory finding whereas at least some other mathematicians aim to build larger unifying structures. It's a sort of Erdos versus Bourbaki divide (not to say who's right).
