Ignorance is bliss?

As we were going through the discussion today about "The Giver," several topics flooded my mind. One thing I began to think about was the common phrase "ignorance is bliss." I feel like every character in "The Community" is ignorant. And is there bliss? I believe it's difficult to say. If you're living in that community, where no one knows anything else besides it, I believe that I would be happy, much like all the characters are portrayed in the book. However, having knowledge of color, animals, love, weather, responsibility, etc. I don't feel like I would ever be blissful in that situation but only happy in the position of knowledgable. It is arguable that for one to know of love and joy that one also is familiar with pain and sorrow. However, on any given day I would take the pain and sorrow with the love and joy than be void of all of it. I believe that only because of the pain and fear I experience I know how much more great is the love in my life.
