Despite his claims, he spends virtually no time dealing with the relevant philosophy and continually falls into: "either freedom involves an absolutely magical faculty and is determined by nothing prior or else it doesn't exist." Most philosophers would say this nonsense. Action determined by nothing prior would necessarily be random, and randomness or arbitrariness is not what is meant by freedom.
What he needs to make an argument for is epiphenomenalism, and that is much more difficult, not least because if how the world appears to us and our experience of choosing NEVER effects behavior it could never, ever be selected for by natural selection. But if how the world appears to us and our reasoning are not selected for, and have nothing to do with how science is done, we lose all warrant for believing in science. Donald Hoffman's The Case Against Reality is also philosophically naive but it is a least a good collection of some relevant problems here.
The whole point is normally that people can be more or less self-determining and self-governing. This goes back to ancient philosophy. Making freedom into a binary is ridiculous, it's a contrary opposition like light and dark, not a contradictory one.
He also cherry picks and is guilty of a sort of bad faith (whether he recognizes it or not) metaphysical flip flopping where he constantly flips between assuming smallism (smaller = more fundamental, all facts about large things are fully explicable in terms of facts about their smaller parts) and bigism (there is only one universal process and since there is only mechanistic causation everything is one system going back to the start of the universe and only arbitrarily divided) whenever it suits his argument, leaving a complete mess of the Problem of the One and the Many that, if pulled apart, could probably lead to showing that nothing can be said about anything. It also tends to be guilty of the trend in popular science to just assume a sort of corpuscular/atomic mechanism, i.e., 19th century metaphysics, as a sort of "default" despite such a view no longer being popular in physics or the philosophy of physics itself (where various interpretations of pancomputationalism are all the rage, and process metaphysics, which makes reductionism questionable). How this "world view" limps on as a sort of popular religion in some areas of the academy is an interesting sociological question though.
