Peter,
As a general strategy for considering a black box, great. As a vehicle for defining a mysterious ‘something’ you want to understand, potentially useful but dangerous. Labelling can make a job harder in cases where the ‘thing’ isn’t a thing at all but a result of your confusion. ‘Free will’ is a good example. It’s like naming an animal you plan to eat: makes it harder to kill.

If you’re contemplating picking the book up, do, it’s really excellent. Conceptually very dense but worth taking it nice and slowly.
