I know that LifeRing - another secular set of tools - calls the two the Addictive Self and the Sober Self (I think, have to look it up).
bemyself, yes, though it's the 'addicted self', not addictive. the division addresses the internal "warring". both the LifeRing A and S and the AV were useful to me at the beginning, though eventually i came to a different view.
Faith: in terms of the Beast, it's not only stupid and cunning, but one ting you can count on: it's got a one-track mind!
no matter what disguises it comes at you with, or how it sounds, know it only has ONE GOAL! really, it's a very boring beast!
