wtf he's giving HIS OPINION. In fact he says as such in his conclusion. "That's what I think it is'
"Thats what I think it is anyways" is from an interview about the book, not from the book itself and uttered less as a disclaimer ala: "this is just my opinion" than as a celebratory reminder to the interviewer & those who'd read the interview of the greatness of himself ala: "it was great & briliiant ME who was smart enough to figure this out", a posture displayed throughout this work by Lewis' (convenient) failure to distinguish what of the NeuroScience he cites is commonly acccepted NeuroScientific fact and what of that are his own conclusions in this area.
Displayed in fact within the very title of the book itself:
The Biology of Desire: Why Addiction Is Not a Disease
which more accurately titled would've been
The Biology of Desire: Why Addiction Is Not a Disease (unless later discoveries about the human brain prove me wrong)
I'm merely suggesting that we don't yet have a comprehensive enough understanding of the Human Brain to frame theories about addiction in the confident tone that Lewis and a company that wants to sell books....do in this instance, as though Lewis has solved a great mystery.
Just a "LOL" moment on my part to someone writing an 800 page book informing us of something we already knew but knew also that we did not know (for sure) because not enough is known about the brain, for us to truly know.
You know?
