There is a lot to know. There is more to know about life and the universe than any one person could ever hope to master. This seems so obvious as to not need pointing out. However, from time to time, we all succumb to the siren song of the absurd. That misfortunate melody tells us we know more than we really do. It is our responsibility to keep ourselves in check when it comes to the knowledge we possess or lack. It is important for us to know what we know and know what we do not know.
