Communication, Practical Logicism, Sufficient Reason

According to Practical Logicism, all Communication is derived from a Rational principle.  Now, one such principle, which can be called the 'Practical Principle of Sufficient Reason', requires of any action A, that it be better to do than to not do it..  But, as has been previously discussed, every Utterance seeks an Enactment from its addressee, and, hence, incorporates some justification for doing so. Thus, every Utterance is an expression of the Practical Principle of Sufficient Reason.  So, Practical Logicism prevails where Theoretical Logicism does not--it applies to Ordinary Language--while, at the same time grounds the proofs of Formal Logic, i. e. the proof a proposition P implicitly attempts to persuade that believing P is better than not believing it.
