This morning I am about my ponderous project of reading Hugh of St. Victor's De Sacramentis, and in I:6:12-13 I arrive at an interesting definition of the content of the Sacred Scriptures:
Before the fall, the human being had three kinds of knowledge that pertained to prelapsarian perfection: of God, of himself, and of the rest of creation over which he was meant to have dominion. This third area of knowledge is revealed in the naming of the animals (Genesis 2:19), as the human being was meant to use his own reason and knowledge to take care of the world.
Now only the first two categories of knowledge were obscured in the fall, so it's only these that are contained in the tutelage and remedy we receive through Sacred Scripture. That's why the Bible doesn't teach anything about math, goat care, or hut construction, because these sorts of knowledge were not obscured by original sin.
