it is the appellation of a thing that brings to light ('posits') its potentials

 When I observe the world around me through the lenses of a language, I

perceive its actuality through the lenses of the potentialities hidden,

latently present, in it. 

What this means is that potentiality appears 'as

such', becomes actual as potentiality, only through language: it is the

appellation of a thing that brings to light ('posits') its potentials
