Words have the ability to create. Specific words evoke moods; meter and sound evoke music. Language enfolds the listener and speaker into fluid feeling.
Words can move, and wound. Rhetoric can build and destroy empire. Propaganda can unify and stultify. Words have power.
That which remains undefineable remains inconceivable, mysterious. It may be approached, but never controlled. But subtlety can delicately poke--
--the ephemera gently evoked may eventually coalesce into some semblance of sense: in the metaphor of the lightbulb popping on, a whole new world becomes available for sensing.
Within this music, language, is the prerequisite~union, between two or more disparate spirits who seek to communicate. It requires both calculation and abandon. It rests upon the razor plane of pleasure and pain. Honesty is an arrow aimed at a place in a person: either in the belly, heart, or brain.
How do we know when to be kind, careful, sane, or sarcastic?
(God) knows.
