We are a social creature

Discuss the biology of our species, the infant's depce as compared to other creatures.  Despite our ostensible isolation, our self-made cocoons of air conditioning and flat-screen TVs, we still congregate for celebrations, we congregate to worship in a place that we consecrated to our chosen Higher Power, etc.  Therefore, much as we behave as if the concept of sin may be outdated, the purpose of the list is to serve as a code of conduct which is never outdated.  Relate to current day.
