The higher we soar in contemplation, the more limited become our expressions of that which is purely intelligible; even as now, when plunging into the Darkness which is above the intellect, we pass not merely into brevity of speech, but even into absolute silence, of thoughts as well as of words ... and, according to the degree of transcendence, so our speech is restrained until, the entire ascent being accomplished, we become wholly voiceless, inasmuch as we are absorbed in Him who is totally ineffable.

(Dionysius the Areopagite)
