Knowledge is power ignorance is bliss

Knowledge is power; ignorance is bliss,
Are they both more, than the sum of there parts?
Tell me good people what has gone amiss?
Two opposite notions born in the heart
Rearrange them both with word interplay
Bliss is power; knowledge is ignorance,
Entwining two sayings like night and day,
Engaging two moves in delicate dance
Then you may be able to understand,
To answer the question, play the right hand.
