Just to butt in, not answering for anyone else. But I’d say that parsing gives the Beast too much credit so to speak. Imbues It with too much gravitas and even too much substance.
The only way the Beast ‘succedes’ is as a parasite influencing a host . The desire for alcohol hijacks the ‘operating system’ of the totality of the complex system we call humans, yeah ?
The Beast isn’t in the same category as a ‘self’ , it isn’t a contest between equals , a negative self as opposed to a true self . Self’s are ‘bigger’ than desires and drives.
Beast as entity isn’t complex in any manner , it is simply the desire for more alcohol. The interactions between the truer self or higher brain functions and the ‘lower’ or more base impulse functions are more complex and reside in a bigger ‘space’.
AVRT exposes the true power dynamic and reestablishes the proper hierarchy.
