As soon as I can.
Honestly, it seems I cannot get enough of this topic. It's only what I consider to be the most fascinating and important of all topics. (Also the most frustrating.) I'm in it for the long haul!

How many rapes are in my genetic history? How many people had to sail from different parts of Europe in what seem to me to be not much more than canoes in order to meet way the heck over on this continent in order to have sex at the exact moment with the exact sperm and egg meeting so their child could travel a couple hundred miles on horse and run into this other person and... It's not possible for me to exist. Go back 10,000 years and we have no means to imagining who will exist today. But it happened exactly as it happened, against a googol-to-one odds.Thermodynamic miracles... events with odds against so astronomical they're effectively impossible, like oxygen spontaneously becoming gold. I long to observe such a thing. And yet, in each human coupling, a thousand million sperm vie for a single egg. Multiply those odds by countless generations, against the odds of your ancestors being alive; meeting; siring this precise son; that exact daughter... Until your mother loves a man she has every reason to hate, and of that union, of the thousand million children competing for fertilization, it was you, only you, that emerged. To distill so specific a form from that chaos of improbability, like turning air to gold... that is the crowning unlikelihood. The thermodynamic miracle.
Argh. Sorry. I didn't word it very well. I meant we can't predict what a computer is about to do by examining every atom. We could be on the holodeck, surrounded by a holo-representation of every atom in a computer. (Whatever scale we want. Atoms appearing the size of grains of sand, or basketballs, or whatever.) I don't imagine anyone would even know it was a computer, much less understand it to the degree we're talking about.Zarathustra wrote:I thought that by determinism you mean that if we understood a system down to its atomic level, we'd understand everything about it. If you know its current state, and the laws describing its change of state, then you ought to be able to predict its next state ... unless something more is going on that reductionism doesn't capture. For the brain, I believe this "something more" that you can't capture is the subjective content of experience (which influences one state to the next). It won't show up under any objective examination of the positions of atoms. The content of a computer program, however, would.Fist and Faith wrote: We can examine every atom in a computer, and have no idea of what it is about to do. The same is true of the brain. Not being able to predict what a brain will do by examining every atom in it is not evidence that the mind is anything other than the brain's activity.
Therefore, since there would exist something that can't be described deterministically in terms of objective matter, then mind is indeed something more than the brain functioning.
This conversation brings to mind an episode of Colombo. He needed to prove this guy did not have ESP. But the guy pulled off an amazing trick. Colombo was being helped by this kid who was an aspiring magician. The kid said something like, "To figure it out, we have to remember it's not real. He doesn't have ESP. It's a trick."Zarathustra wrote:What's the difference between a) natural selection shaping our genes and b) humans shaping their own genes through genetic engineering--if everything reduces down to particles/forces/fields?
What is time? Is our perception of time passing an illusion which hides a deeper, timeless reality? Or is it real, indeed, the most real aspect of our experience of the world? Perimeter Institute Faculty member Lee Smolin examines these and other timely questions from his book Time Reborn during his April, 2013 Perimeter Institute Public Lecture.
Smolin's new book, co-authored with Roberto Mangabeira Unger, is The Singular Universe and the Reality of Time. Find it here: https://www.amazon.com/Singular-Univers ... 1107074061
The point, as I hope the above-posted video will begin to make clear, is that we don't "know" any such thing about "starting points" (that is, nothing other than the "real-world/real-life/common sense" starting point I mentioned on the last page of this thread).Fist and Faith wrote:I'm not saying we're dealing with an illusion. I'm saying we know what our starting point is. We have to build the answer from particles up, and never forget that it all comes down to particles.
Correct only in the sense of, "the natural laws we know." It's time to expand our knowledge of natural laws.Fist and Faith wrote:It seems to me you are looking at this impossibly complex thing - the mind - from the end, and saying it could not have come about. ... I think it's more accurate to say you believe the mind cannot exist within, or maybe cannot have come from, the natural laws we know.
Taking one at a time:-The mind controls the body.
-It does not do so by means other than bio-electrical/chemical.
-It cannot use those means without being of those means.
-If it is of those means, it is subject to the same properties/characteristics as everything else made of those means.
This is dogma and/or a failure of imagination. Materialist reductionism isn't the only possible way for things to be "natural." That's an assumption, based on the success it has had under Newtonian physics. But we've known for 100 year now (due to quantum mechanics) that this metaphysics is naive.The degree to which my answers are not satisfactory are due to the fact that I am not the right person to be answering. ... But the answer must be in this stuff. The alternative is supernatural, by the literal definition.
Why are you so certain about something you don't understand? Don't you see how that is a philosophical position, and not a scientific one? I get it, you've committed. You have picked an ontology. But your refusal to admit any other alternative is dogmatic.Me: "The mind exists in, and continually interacts with, those laws. It is part of those laws. It cannot not be. The explanation cannot be elsewhere. We just haven't come to understand it yet."
While mind is dependent upon particles (i.e. they are necessary causes), it is not entirely dependent upon them (i.e. they aren't sufficient causes). Mind is also dependent upon immaterial things like meaning, ideas, intentions, etc. There are necessary constituent structures, phenomenological structures, without which there would be no consciousness. For instance, without conscious of something, there is no consciousness. That "something" (the intentional object) is hardly ever a particle (except when we're thinking of particles).There is no freedom from the realm of particles. The mind is entirely dependent on them. We can easily demonstrate this by removing or adding particles (brain injury, hormones/chemicals), and watching the mind change. Or disappear.
We clearly don't know everything about the universe, so we can't say definitively "how nature works." Just because starting from particles and working our way up works for some inanimate objects doesn't mean it works for everything.I'm saying we know what our starting point is. We have to build the answer from particles up, and never forget that it all comes down to particles. When we look for the answer outside of the ways nature works, we have gone off track. We know this, because the mind, controlling the physical body by physical means, reveals that it is of the same system.
So, the choice is either 1) the absolute knowledge of a reductive model or 2) no knowledge whatsoever?Fist and Faith wrote:I think we know a few things. I don't think the only way to learn anything about reality is to leave it and look back at it.
I'm not sure that chess program idea isn't what we have. At least at times. Sometimes I do have a clear favorite. Things that I'm sure are part of my wiring. Bach over Mozart. Chocolate over strawberry. But sometimes it's not that easy and obvious. Sometimes I sit at a restaurant for fifteen minutes, telling the waiter to come back in a few, because I can't decide between X and Y. So how did I make the decision? Many times I ask which is a larger amount of food, and go with that. If there is no clear answer to that question, I pick randomly. I cannot claim to feel anything other than randomness. Blind hope that I don't regret my choice.wayfriend wrote:Without rehashing old arguments .... it's clear that, until we figure out what the source of consciousness is, whether it reside in the physical or not, we're not going to replicate it in a machine or in software. Not unless there is a happy accident. In the mean time, people strive (in their ideas, anyway) to create an illusion of free will by using randomness, which is then filtered by feedback and machine learning until it produces something which is both intelligently directed and yet unpredictable. (Like a chess program which calculates the best three moves to make and then randomly picks one.) However, that to me is not free will, just the illusion of it. You can be a slave to random numbers as much as you can be a slave to deterministic causality.
I don't disagree with any of that. It depends on what we're supposedly free from. "It brooks no other sovereignty" says it very well.wayfriend wrote:A phenomenon outside the limitations of cause & effect is supernatural.

Consider this "choice engine" that you propose. It is built upon preferences and experiences and inborn nature - just as you say. And it runs deterministically, of course.Fist and Faith wrote:So we debate the two. And we come to a conclusion. How is this not the result of cause & effect?
But the sum of your preferences and experiences and inborn nature is you. You are the choice engine. What it chooses is your will.
The problem isn't that determinism excludes free will. The problem is that your free will is deterministic. "Free will exists in a matrix of cause and effect."
But how is this not "free"? Would being subject to random impulses interfering with your choices make you free? Would being influenced by a supernatural phenomenon make you free? In my mind, that makes you a subject to whims beyond your control ... that's slavery.
Think, instead, that your will, as a deterministic choice engine, faithfully (that is, without external influence) renders your choice based on your preferences and experiences and inborn nature. Your will rules. It brooks no other sovereignty. That is "free".
This is why determinism is no excuse for your actions: the choice was made by a choice engine which is your will. Your will is responsible for the choice.
The only thing left to deal with is a vague notion that if your will is deterministic that it is somehow less than wonderful. But that's just vanity in the end.
