The lightning flash provides insight, but a tone echoes through memory. Meanings fade, sense alters with perspective, and a fact's only constant is the historical power of whoever's values are in authority. Language mutates old messages dulled by such power because sound demands an outlet to be heard in the enduring present. As reason fails us, sound's legion flails dust from arms heralding signs of alphabetic succession. On a banana peel with this little piggy all the way home.
Consonants are a means by which sound is refrained from the flux of infinite bowels.
Unlike vowels, airs are obstructed, the pneuma is shaped by the character of its container. Air is released like gas hissing over the tongue. Thus, one can understand pneuma as spirit by its sounding. The sound replicates the meaning by a demonstration of breathing. The ability to plot these consonants as on a graph is a process of sounding which Velimir Khlebnikov explained in his theory of internal declension.
