potentiality

The boon of language is not tenderness. All that it holds, it holds with exactitude and without pity, even a term of endearment; the word is impartial: the usage is all. The boon of language is that potentially it is complete, it has the potentiality of holding with words the totality of human experience -- everything that has occurred and everything that may occur It even allows space for the unspeakable. In this sense one can say of language that it is potentially the only human home, the only dwelling place that cannot be hostile to man. For prose this home is a vast territory, a country which it crosses through a network of tracks, paths, highways; for poetry this home is concentrated on a single center, a single voice, and this voice is simultaneously that of an announcement and a response to it.
