Ignorance is bliss.. trained capacity to ignore is greater than that

Our eyes, ears, nose, skin, and tongue.. 

and of course the mind too.. 

are 

created primarily to embrace everythig.. 

be it good or bad

Actually they do not have any idea as to what is good or bad..

But if we have to survive, we should know more about what not to embrace.. than what to embrce..

Ignorance is bliss..

but the trained capacity to ignore is greater than that.
