At the end of the second verse you hear: “At least I know that I don’t know, question is are you bozos smart enough to feel stupid”
“Socrates was the smartest because he knew that he didn’t know much”
Then he asked to some other villagers if they thought they were smarter than him because he didn’t want to believe that he was the smartest of them all.
Is Eminem talking about that?
PS: Sorry for the bad english!
