I enjoyed the article. I’m still skeptical of the caveat, “in a natural universe governed by deterministic laws” because that’s not a complete view of cosmology and it seems a bit naive at this stage to link two unknowns together, plus the term “free will” and “neurological volition” don’t seem complimentary.
Decision making is too broad to narrow into one hole. Bad decisions are made all the time. Neurology is helpful here only to researchers. Parsing it all into some abstract debate about a concept called “free will” seems to miss the point.
What we do have is a “will”. That may have many influences, neurologic as well as environmental and most importantly, personal.
Speculating about a deterministic universe without any transcendent seems pedantic and may not help us solve any real problems or make any better decisions .
