The true sign of intelligence is not knowledge but imagination.
Talent hits a target no one else can hit; Genius hits a target no one else can see.
To expect the unexpected shows a thoroughly modern intellect.
I don't even call it violence when it's in self defense; I call it intelligence.
Your intellect may be confused, but your emotions will never lie to you.
There is no great genius without some touch of madness.
I'm not the smartest fellow in the world, but I can sure pick smart colleagues.
Franklin D. Roosevelt
