Justifying Life's Rules

If we have no rules, life becomes chaotic.  Having too many, or having ones providing too great a penalty, is to be constricted.  Not having certainty that there are rules at all, or concern they might change, makes life too tentative.  There need to be rules, but they need to justify themselves so there will be less likelihood of their changing.  A proposition may become a rule if it is universal, or almost so -- if it always applies; if it provides a basis for prediction; if it is the same across conditions; and if it applies to most people or most can agree on its reasonableness.
