“HOW much more powerfully do the laws of man's nature move him to hold fellowship and maintain peace with all men so far as in him lies, since even wicked men wage war to maintain the peace of their own circle, and wish that, if possible, all men belonged to them, that all men and things might serve but one head, and might, either through love or fear, yield themselves to peace with him! It is thus that pride in its perversity apes God. It abhors equality with other men under Him; but, instead of His rule, it seeks to impose a rule of its own upon its equals. It abhors, that is to say, the just peace of God, and loves its own unjust peace; but it cannot help loving peace of one kind or other. For there is no vice so clean contrary to nature that it obliterates even the faintest traces of nature.”
~St. Augustine: The City of God, Book 19, Chap. 12.
