And which of those desires prevails is a "free" event, not predictable in advance.Although our desires cannot be calculated, much like predicting particles cannot be calculated, we still can have many desires at any given moment
You're doing it again. You have changed the word "strong" to "dominant" but still have assigned no meaning to the word, while admitting that there is no way to assign any meaning to it. The question is, BEFORE the choice is made, is there some way to RANK the various desires, saying this one has "more" power than another? The answer appears to be "No"; only AFTER the choice is made can you say, tautologically, that the desire which won is the desire which won.which begs the question, "Is our chosen action based on the most dominant desire?"
I haven't taken any offense.I don't mean to offend if I have offended you
Your initial way of phrasing it was ultra-condescending, taking for granted a lot of things which are not just controversial, but to me seem obviously wrong-headed.but your initial approach to this assignment was to say the least, "condescending" at best.
I would agree that we do not yet know enough to prove anything. But a simple-minded mechanistic determinism, where everything must have prior physical causes, and competing influences must have quasi-numerical rankings that decide which one dominates the other, is just not adequate anymore.The truth is that Quantum Physics leaves a great deal of related questions unanswered, which is why it cannot yet prove freewill, just as it cannot yet disprove Con freewill.
Roger Penrose's "The Emperor's New Brain" was a good layman-accessible read on the difference between computers and us. You can Google Penrose for more literature on the subject; the Wiki on him has good links to the views of his opponents. He notes that much of our brain is, of course, devoted to running complicated "programs" in an algorithmic and deterministic manner, but that is not all that is going on. For example, I get in my car, start thinking about something else, and find that "my car has driven itself" to my old place of work, where I did not need to go anymore; but this is precisely what we call "mindless" behavior, the opposite of "choosing" (whatever that consists of). We walk, without having to calculate, as a toddler must, the exact balancing of the feet at every moment, because the program is in there and we can now just execute it; but deciding which way to walk is something else.Thanks for this. So are you saying that the brain may have an interface that allows free events in the quantum world to generate an impact at the larger scale deterministic world? If so, could you direct me to articles/links on quantum effects and the brain processes? I would like to find out more as this is an area that I've been thinking about for some time.
Penrose was very excited about the "microtubule" structures in the neurons: these are long-chain molecules, with a + pole at one end and a - pole at the other, inside a sheathing sort of like a "Faraday cage" (something that isolates what is inside from external electric fields) so that the polarity can shift from one end to the other in a totally free manner. But then it turned out that similar structures are in all kinds of other types of cells, so his critics think it cannot really have all that much to do with "mind". Well, I think that this proves that life itself uses a lot of the "freedom" which the physics allows. An amoeba is particularly thick with microtubules all over its cell membranes: now, the membrane is not just the "skin", it really is the nervous system, the interface with the outside world, the way the amoeba senses what is out there and reacts by extruding pseudopods to try to grab this or that, or move this way or that. I believe that the amoeba, which we think of as so "simple", is already too complex to be emulated by a computer; that its "decisions" about where to extrude pseudopods are already an exercise in free will. It may not have much scope of its agency, but in so far as it is able to act, it acts freely.
