"First of all, principles should be general. That is, it must be possible to formulate them without use of what would be intuitively recognized as proper names, or rigged definite descriptions."

I am somewhat uncertain whether there is a definite factual question as to whether natural language handles truth-value gaps. Nor am I even quite sure that there is a definite question of fact as to whether natural language should be evaluated by the minimal fixed point or another, given the choice of a scheme for handling gaps. We are not at the moment searching for the correct scheme.
