ignorant + arrogant = a word to describe people in their present societies who believe that their way of doing things is the most correct while ignoring that every 50 years or so we laugh haughtily at the errors of the fools before us, thereby creating a continuous repetitive psychosis of "We must be correct now!"
-You know those people (everyone) who thinks we've developed the most forward thinking society?
-Yeah.
-We're so ignorrogant.
