The mask slips
So now you are responsible for choosing your leader. Do you want someone like you or someone better than you?
Get that? Not smarter, not more experienced, better.
The problem here is the good professor doesn't know what "better" means. The better man is the braver man. The better man is stronger in character. Better often has little to do with smarts and is frequently found in inverse quantities. If the professor were a better man, he'd know that.
