to evil by sin. And to every good thing evil is joined as by a certain covenant of alliance on the part of sin, since indeed the earth has been polluted with human blood, and altars have been lighted to demons, and they have polluted the very air by the filthy smoke of sacrifices; and so at length the elements, being first corrupted, have handed over to men the fault of their corruption, as roots [communicate their qualities] to the branches and the fruit.
Chap. lii.—"No rose without its thorn."
"Observe therefore in this, as I have said, how justly divine providence comes to the help of things vitiated; that, inasmuch as evils which had derived their origin from sin were associated with the good things of God, He should assign two chiefs to these two departments.

Chap. LIII.—Everything has its corresponding contrary.
"Therefore this division holds in all the things of the world;
