Is Ignorance Really a Bliss?

We had a little debate if Ignorance is really a Bliss as we move forward in life... I continue to look at this with amazement.

There have been lot of instances where i wish i could have been a little more ignorant... I would have felt more like a child than like a man and i guess, it helps being a child at times lookin at things in awe and not with words that substantiate every stance!

There are umpteen other instances where i wish i had been a lot less ignorant that could have done a world of good... or does this stem from the belief in my mind tat experiences make a man which in other words mean, exposing yourself to a learning process that makes you more infallible!
