While 'just the facts' may be a great way to conduct an investigation, Joe Friday would have had a terrible time trying to live his day to day life based just on 'the facts'.

Most of our most important decisions in life are based on feelings and beliefs, not facts. We choose our spouses based on feelings, and our relationships with our families are definitely guided more by feelings than by reason. We choose things like church membership based upon our beliefs- or absence thereof. Even the political parties we adhere to are based on beliefs about those parties rather than facts, and political parties are a great example of how perceptions about a party shape its policies, and not the other way around. (Look beyond recent history!) Concepts like Patriotism are feelings, and many of these feelings become values, both personal and social.

We cannot live without facts. Facts give substance and definition to reality. We cannot, however, deny our feelings and beliefs because they ultimately serve the same purpose: defining our reality. Trying to live one's life by denying any one of the three- facts, feelings or beliefs- deprives us of meaning.

This is over-simplified but I am sure you get my gist. No reason to write a treatise when a few simple sentences will make the same point.
