The Need to Categorize

If there are but two categories -- such as good-bad, right-wrong, black-white -- everything must fall into one of them, when in truth most things are far less absolutely either way.  They are really pretty neutral and are all right for being so. It is what they are meant to be.  Yet, some of us need to categorize and insist others do so as well, which is not so terribly helpful for anyone.  We then talk in classifications that do not apply, in those absolutes that have so little foundation.
