" A ship with two of every animal in the world, my friend? That would have to be a very large ship indeed. Is that how you would save a world? A bull and a cow, a sheep and a ram, and so on? The people who wrote your Torah, my friend, must have had poor livestock if they raised their herds from only one dam and one sire, breeding sisters with their brothers, any herdsman knows that this does not produce a healthy flock.

No, my friend to save the world you save the knowledge of that world, the knowledge that there were bulls and cows in it, that there were sheep and rams in it, that there were men and women who lived and died. If your world is to be destroyed, all you can save my friend, is the knowledge of it, to restore what you once had, to mourn what can never be restored. "

― Hal Duncan , Ink (The Book of All Hours, #2)
