The greatest authors and instigators of evil are ignorance, self-love and tyranny. Each depends on the other two and is supported by them: from ignorance of God comes self-love, and from self-love comes tyranny over one’s own kind. The devil establishes these in us when we misuse our own powers, namely our intelligence, our desire and our incensive power.
Since self-love is, as I have said, the origin and mother of evil, when this is eradicated all the things which derive from it are eradicated as well. For when self-love is absent, not the slightest trace or form of evil can exist in any way at all.
