Hi P A
When you say
'ignorance is the key word i suppose'
you bring out the pun meanings of the word and cause us to face the 2 meanings. Seeing both sides of puns together are supposed to reveal the true reality.
In your example we know to be our brothers' keeper but are ignorant of all the factors that led to him bleeding.   If we ignore those factors we are left with the only true meaning--our actions must be based upon love.
I don't know what religion or philosphy pun wisdom comes from---Buddhism maybe? Have you heard?
