[Verse 1] I know what I know Don't tell me I don't "don't tell me..." I built my world From the things I was told Every fact I never checked Every fear I learned to protect Put it in a box, put a lock on the door Then I hammered down another board "Mmm... that's right..." "That's right..." I don't need the truth If the truth won't agree I don't need a question When the answer is me [Pre-Chorus] And I feel it rising "right behind my teeth..." That little certainty "mmm... underneath..." You can tell me I'm wrong I can tell you you're blind We can both stand screaming With the world left behind [Chorus] Nothing in all the world Is more dangerous... "dangerous..." Than sincere ignorance "ignorance..." And conscientious stupidity "stupid... i-tee-ee..." Nothing in all the world Is more dangerous... "ohhhhh..." Than a mind so sure It don't need to know "don't need to know..." [Post-Chorus] "Mmm-mmm..." So sure... "so sure..." "Uh-uh..." So sure... "so sure..." [Verse 2] I can make a weapon Out of what I don't understand "understand..." I can turn a question Into something I command "command..." I can close my eyes And call the darkness clear "clear..." I can feed the little monster Every rumor it wants to hear "wants to hear..." Facts don't matter When the feeling's loud "NO, NO, NO..." Truth gets smaller When you gather up a crowd "Huh!" And everybody's certain Everybody's right Everybody's holding A match in the night [Pre-Chorus] And I feel it rising "right behind my teeth..." That little certainty "mmm... underneath..." If I never stop I never have to see The damage I can do To you "or me..." [Chorus] Nothing in all the world Is more dangerous... "dangerous!" Than sincere ignorance "ignorance..." And conscientious stupidity "stupid... i-tee-ee!" Nothing in all the world Is more dangerous... "OHHHHHH!" Than a mind so sure It don't need to know "DON'T NEED TO KNOW!" [Instrumental Break] "uhhh... uh-uh..." "mmm-mmm..." "no-oh..." "no-oh..." [Bridge] I stopped at the door And called it the end "the end..." Built up the wall Then called it a fence "a fence..." I heard only myself And called it the truth "the truth..." Held tight to the lie Because letting go hurts "hurts..." No room for doubt "no room..." No room for anyone "anyone..." No room for the world To be anything But what I had decided "Mmmmm..." [Whispered] I don't know. [One beat of silence] [Full band explodes] I DON'T KNOW! [Final Chorus] Nothing in all the world Is more dangerous! "DANGEROUS!" Than sincere ignorance "IGNORANCE!" And conscientious stupidity "STUPIDIDITY!" Nothing in all the world Is more dangerous... "more dangerous..." Than a heart that won't listen "won't listen..." And a mind that won't know "won't... know..." "I DON'T KNOW." "Mmmmmmmmm..." "Don't need to know..."
