The animal separation part is confusing to me. Not because of any "mind versus matter" dilemmas but because of desires.

The author says that the animal wants to relax and lie down. But where is the distinction here? If you drink coffee when you feel the urge - that's on you, but if you relax when you feel like it - then it's the animal? Can it be that all those desires for working hard and having coffee and alcohol was part of the animal instinct?

I don't see how to decouple those, even thou I am sympathetic to the animal / inside animal distinction.
