Ignorance is Bliss

I disagree with the phrase 'ignorance is bliss.' In my opinion bliss is a state of mind where one knows of the pain and suffering in the world, or has experienced it, and has reached a point in their life where they are o.k. with their past or knowledge. Bliss is when one understands all there is to understand, and is at peace with themselves and the world despite any and all troubles. In my mind the two words ignorance and bliss are complete opposites, and they do not go together.
