What is it?
What is it that you think you know? And where might you have learned it?
From books you’ve read? From things you’ve heard?
From facts you took at someone’s word?
Did you pass the test? Did you make the grade? Did you nod your head?
Have you always obeyed?
Would a knife draw blood inside a box?
Or might you need to wield the blade?
