Update on Free Will

Currently I am reading two books by authors with similar names neither of which I had heard before. I have already commented on Sam Pizzagati’s The Rich Do Not Always Win, an history of the early twentieth century that resulted in the largest middle class in American history. I strongly recommend this book as the rhetoric on both sides of the “wealth inequality” debate is quite illuminating.

The second book is by Michael S. Gazziniga entitled Who’s in Charge?: Free Will and the Science of the Brain. This book is fabulous as it is written by a neuroscientist, one who is taking his fellow scientists to task in the free will debate.

I have previously argued that it is far too early in the scientific investigation of free will to come to any conclusion, certainly not one with such large ramifications as whether we have free will or all of our decisions being determined by physical causes. This author provides a piece of this discussion that I had not heard before and it is a lollapalooza.

He starts with addressing free will in the context of responsibility, the primary question is “Can we hold people responsible for their decisions?” (If not our criminal justice system is far worse off than it already is.) This is enough of a foothold on free will to proceed. After going over the neurological research that seems to apply to the question he makes the following argument: consciousness is an emergent property of brains possessing enough connections. This is not a revelation, most people buy into this conclusion. He then goes on to claim that emergent properties represent a disconnect from the basic physical conditions that create the property in the first place! If this holds up, then determinism is done for, toast, kaput, won’t apply, because there are quite a few layers of emergent mental properties stacked up that the basic physical entities (atoms, molecules, DNA, genes, etc.) will not be able to get through.

He gives as an example the building of a car. A careful designer can create a car with its engine, transmission, differential, wheels, tires, electronics, etc. that will perform pretty much exactly as designed. (I have just finished reading a book on the design of the most recent iteration of the Ford GT race car. It was designed to win the 24 Hours at Le Mans race … and did. This is an example of determinism, the whole being the sum of its parts.) But … you knew that was coming, didn’t you? … but none of a car’s physical parameters, its specifications, can explain … traffic. When you take automobiles and roads, traffic shows up as an emergent property and traffic cannot be predicted from nor can it be determined by any car’s design! And if this weren’t enough, the author claims that the emergent properties affect the original vehicles through feedback. For example, this souped up race car might overheat badly in beep and creep traffic, so has to have to be modified or just garaged and not driven on normal roads. (I haven’t finished this second part of his argument but basically he argues “that the mind, which is somehow generated by the physical processes of the brain, constrains the brain.” The mind constrains the brain. Think about that. (There are many examples of this happening, but like I said I haven’t finished this part yet.)

This argument about emergent properties blocking deterministic causes seems to blow the argument of free will v. determinism out of the water with determinism the loser. We have to wait and see if it holds up.

So, what do you think? Is consciousness and therefore free will determined such that we actually have only the illusion of free will and making our own choices, or is making conscious choices an emergent ability not determined by physical inputs to our brains? (The author explains why we all have the perception of an “I” making decisions by the way, even though “I” does not exist.”
