Now this fourfold divine revelation, embracing the two external branches of Scripture and of nature, and the two inner ones of conscience and devotion, has its seat in the four faculties of the lower order which have so repeatedly been brought before our consideration. For the memory is the organ of its written and oral transmission and perpetuation —nay, of writing and language generally, according to the intimate connection which subsists between them. And in the next place, the external senses, with which we may also associate an immediate intuition into the depths and mysteries of nature, are the organs for perceiving and understanding the sensible phenomena. Lastly, there is conscience, and, on the other side, a longing after God and divine things, as the highest and most enhanced degree of human pursuit—of the profoundest aspiration of man's soul, and the purest desire of his spirit.
