Many Christian people rise a little higher; they conceive that even grammar and arithmetic may in some not very clear way be used for God; but the great recognition that God the Holy Spirit is Himself, personally, the Imparter of knowledge, the Instructor of youth, the Inspirer of genius, is a conception so far lost to us that we should think it distinctly irreverent to conceive of the divine teaching as co-operating with ours in a child’s arithmetic lesson, for example. But the Florentine mind of the Middle Ages went further than this: it believed, not only that the seven Liberal Arts were fully under the direct outpouring of the Holy Ghost, but that every fruitful idea, every original conception, whether in Euclid, or grammar, or music, was a direct inspiration from the Holy Spirit, without any thought at all as to whether the person so inspired named himself by the name of God, recognised whence his inspiration came.
