"Purity is Obscurity"

I have been asked why purity is obscurity. I did not name my blog this way as any kind of political statement or expression of my moral beliefs. In my first post I mentioned that I decided to start a blog while reading Ogden Nash poetry. "Purity is Obscurity" is the body of a poem by Nash entitled, "Reflection On A Wicked World". So, the name of my blog is really an homage to the artist, not a comment on the state of humanity.
