1 From whence come wars. As he had spoken of peace, and had reminded them that vices are to be exterminated in such a way as to preserve peace, he now comes to their contentions, by which they created confusion among themselves; and he shews that these arose from their invidious desires and lusts, rather than from a zeal for what was just and right; for if every one observed moderation, they would not have disturbed and annoyed one another. They had their hot conflicts, because their lusts were allowed to prevail unchecked.
It hence appears, that greater peace would have been among them, had every one abstained from doing wrong to others; but the vices which prevailed among them were so many attendants armed to excite contentions. He calls our faculties members. He takes lusts as designating all illicit and lustful desires or propensities which cannot be satisfied without doing injury to others.
