If we are a meat machine and the process is bound by cause and effect, the laws of the physical universe, what makes the choice?
Us. That whole process = us making a choice.
If the result is inevitable, where is a choice made?
I don't know that it's inevitable.
Can a proton choose whether or not to cross a membrane? Can a synapse choose whether or not to fire? The process may be what we call choice, and it looks like choice or will because the input is too complicated and the wiring too little understood to make predictions or anticipate the outcome, but seriously, where is there true option, under some kind of conscious control, at any step of that process?
I have always thought, since reading IIRC Epicurus, that it makes absolutely no difference to anything whether all of life is predetermined or not.
Notice, as soon as you say, "conscious control," you are picturing that little person again sitting in the cab of the meatmobile, controlling it. As soon as you can really, truly eliminate that way of thinking about it, then you may be better able to see it as I do. Yes, "we" have free choice. "We" = that entire process. That's what we mean by "us" choosing. Yes, even though we are purely physical.
Although I don't know that I've ever gotten anyone else to see it my way! :areyoucra
Even if it pans out that due to quantum mechanics there is fuzziness that translates to randomness in chemical reactions (now wow - that's going to blow the mind of a lot of chemists!), there is no 'tiny invisible man' sorting out the random events, shuttling the ones he likes into the process - is there? Where is the conscious control there?
Remember, there is no separate conscious to control. The actual chemical electrical process = choice. When we choose something, certain neurons have to fire, etc. Choosing is itself a biological process, involving our brain.
Exactly. How is that wiring changed? - By the sensory input it receives. Let me say that again. How is that wiring changed? - By the sensory input it receives. See, you read that sentence twice and now that neural network is stronger than if I just typed it once.
Yes, that's right.
If there is no "I" there is no "you" to consciously change what you think and what you think about. "You" are a meat machine, bound by the laws of cause and effect.
Yes, I'll agree with that. Did you think you could somehow escape them?
Yes, you said that and I see the practicality in that. Seriously, I'm not sure what else we have.
Our inability to predict just means that there are too many variables, many of them unknown, and the machinery is just too complex. And as we just discussed above, the machinery changes as it is used.
Maybe. It may have something or other to do with the lack of certainty/predictability at the heart of it, the quantum processes.
Although truth to tell I'm not very good at science and don't actually understand quantum mechanics except in the vaguest way, so I could be way off. I have an idea that you can't really say a quantum particle is at location going y speed, you just have a sort of cloud of probabilities, which is shaped a bit like a globe (?).
Yes, we can make a lot of predictions about behavior because of the dependability of cause and effect, although human choices are one of the areas where we are most in the dark.
But isn't it interesting, we think we have little captains turning the wheel of our ship, but in the end our actions really are rather predictable, which brings that notion into question.
I don't think we've yet addressed how any meat machine can have will, free or otherwise.
Well, do you think your cat does?
I am going by the idea that we are fully meat machines. I put "I" and "you" in quote marks when I am trying to get at exactly what it is that chooses anything, at any level.
Just as long as you remember that in Autodidactism, you ARE the meat machine.
