If the mind is the result of brain activity, i.e. a biological machine, there must be a mechanism for choice-making…
Yes, but so what? The implication here seems to be that one should deny observations for that which one doesn’t have exhaustive explanations, which is to say, all claims should be denied and soplipsism embraced.
If that’s not the case, then “black box empiricism” is wholly sufficient for our purposes here. Humans appear to have agency, as evidenced by their own sense of possible live choices available at various decision points, and also by their unpredictability and ostensible initiative when observed by others.
That’s all.
What is ironic about this is exchange is that it is the materialist that can point to
some mechanism and and model that accounts for cognition in concrete, physical terms. Perversely, this is seen as a
fault by those who embrace superstitious ideas of some “supernatural agency” – a posit
totally devoid of substantiation, mechanism and grounding in reality. It’s as if those who REALLY BELIEVE IN SANTA took to scoff those who were asked to explain how and why the Santa meme worked with kids, and said they weren’t sure where it all got started as a tradition, etc…
There is no tension in saying that like all the other phenomena we see in nature, we reasonably expect that this one – human cognition – has mechanistic explanations that describe and account for it, and acknowledging that our knowledge of those processes is limited at best at this point. A hundred years ago we didn’t know about DNA, and a supernaturalist could have similarly mused that heredity was obviously miraculous and supernatural, as if it weren’t, then one must explain how it happens naturally!
That’s foolishness, and a transparent attempt to burden the other with a burden for explanation that doesn’t obtain. We observe choice. Whatever the mechanism is, we infer there is a mechnamism and governing set of processes at work by inference – that’s how the rest of reality works, so far as we are aware. Even simple things like friction are notoriously hard to explain and model, even now, but we don’t get tripped up by the goofy notion that since the exhaustive model of how friction works is still ahead of us, friction doesn’t obtain, or that it is somehow ‘magic’.
We give reasons for our choices but, generally speaking, not explanations of what enables us to make choices.
Again, a materialist can give an account that is by no means comprehensive or even robust, but just embarrasses a supernaturalist account, which is by rights no account at all, offering nothing that can be checked, modeled, verified or substantiated.
But the hypocrisy at work, here, as risible as that is, is a red herring. Saying that, as a theist, you simply “accept it as a fundamental reality” means you have accepted the worst-case scenario in terms of reasoning. You have punted, abdicated, switched your mind off to probing it further. That’s fine, that’s your right. But you are approaching this from the most irrational position possible – hand waving as a means of opting out of the question, pushing the problem towards magic where it is beyond the reach of analysis and assessment.
None of that has any bearing the matter that got this going. If you think it does, maybe you can point out what relevance this kind of response has to the subject being discussed here:
tonyrey:
Please explain how you choose to act in one way rather than another. What is the mechanism by which you make your choice? Is it located in the brain? If so where?
Don’t get me wrong. That’s a deep and fascinating question, but it’s not relevant for the objective/subjective distinctions at work here re: morality. And you should welcome that realization, for as you know, you offer the weakest of all non-answers to these very questions to be had. Whatever struggles you can put Leela through here, as a diversion, she will be well ahead of your hand-waving on this, even so. Perhaps she’s just too polite to point that out, but you underestimate your readers if you think “prove precisely how free will obtains” is a requirement for any of the questions in play here, not to mention how the sword you wield here does much more damage to your own beliefs than it can to Leela’s or mine.
