I understand what both of you are saying, and based on my understanding, you are both correct.
Try this on: When we speak of The Beast, this is a construct that helps us to understand that while the addictive desire of the limbic system is a genuine part of us, it is a lower part of us. It is all animal and all about pleasure. Our higher selves have the ability and power to dominate and overrule our lower selves."
The Beast is a part of me, but I can control myself, despite it's desires.
