You seem to be defending the notion that entropy = asymmetry. — apokrisis
The essential difference here would seem to be that we call purpose conscious when it involves a conscious choice. That is, when the organism knows it is doing one thing and not another. — apokrisis
So when we watch a creature act, we might be able to see it could have acted differently, but is that a choice it was aware of? — apokrisis
I think I am defending the notion that entropy-in-action is asymmetry in action. Maybe the state of maximum entropy (heat death?) can be understood to be, in some sense, a maximally symmetrical state, but I have also heard it referred to as a state of maximum disorder, which suggests maximal asymmetry. — John
Torquato and a colleague launched the study of hyperuniformity 13 years ago, describing it theoretically and identifying a simple yet surprising example: “You take marbles, you put them in a container, you shake them up until they jam.”
The marbles fall into an arrangement, technically called the “maximally random jammed packing,” in which they fill 64 percent of space. (The rest is empty air.) This is less than in the densest possible arrangement of spheres — the lattice packing used to stack oranges in a crate, which fills 74 percent of space.
But lattice packings aren’t always possible to achieve. You can’t easily shake a boxful of marbles into a crystalline arrangement.
Did you want to distinguish now between sentience (in jumping spiders), consciousness (in squid) and self-consciousness (in language-equipped humans) now? — apokrisis
I was just emphasizing the point that it is not nonsense to talk about non-conscious things behaving purposefully, and therefore intentionally. — Metaphysician Undercover
Claiming that non-conscious objects have a purpose is, in English, an abuse of language. For Aristotle you can get away with it, since "purpose" can be conflated with "cause" and for Aristotle's first three causes the dumb effects of pure deterministic effects came into play. For his fourth cause you get a telos, which has to include a conscious purpose (unless you believe in god - then every thing and all cause is purposeful). — charleton
Claiming that non-conscious objects have a purpose is, in English, an abuse of language. — charleton
If you accept the Popperian conception of knowledge, that it is a type of information that, once instantiated on an appropriate environment, causes itself to remain so, then the genome certainly possesses knowledge if not purpose. — tom
Yes I agree, but we've been through the two distinct meanings of "chance" already. When referring to a possible future event, we refer to a chance that it might happen. This is the principal use of "chance", to refer to a future possibility, and this may be a useful tool in making predictions.Chance, in science, is not a "myth", it is a tool for making predictions about nature. A valuable tool that cannot be avoided at this point in scientific understanding. — m-theory
The reason randomness is necessary is because many causes may have the same probability of occurrence such that any particular cause is therefor unknown. — m-theory
By saying that randomness and chance "play a role", you imply that these things are acting in a causal way. The only way that randomness and chance can play a role is through the mediation of intention. Heads I win, tails you win. But the intentional agent must set up the parameters of the chance event (choose, and flip the coin), and fix things such that one outcome will cause X (I win), and the other outcome will cause Y (you win). Otherwise, the coin is just lying on the table and it doesn't play a role in anything. And even if you assume that coins are just naturally flipping, it makes no difference whether they land heads or tails, unless the intentional agent sets something up, such that heads will be interpreted as I win, and tails as you win. Without intention, randomness and chance, if they could exist without being designed, couldn't play a role in anything, they would be just continuous, ongoing, randomness and chance.There is plenty of technical dissemination of information surrounding how randomness and chance play a role in causation within the context of evolution. — m-theory
When we say an event occurred in the past and we are dealing with probability we are saying the outcome could have been any number of things all with equal chance to occur just because only one of these occurrences happens does not mean it is not random it only means that any given occurrence is mutually exclusive of the other occurrences. — m-theory
I am saying...like in the coin example.Let me get this straight. By "outcome", I infer effect, rather than cause. So are you saying that when a particular event occurred, in the past, the outcome (effect) of that event could have been other than it was? How could the outcome of an event be different than it was, without actually changing the event? In which case, it would not be the same event. So it would not be the case that the said event had a different outcome, it would have been a different event altogether. Therefore it appears to me, that to say that the outcome of a past event could have been different is incoherent. To have a different outcome would require a different event, such that there could not have been a different outcome from the same event. A different outcome would require a different event.
I am saying...like in the coin example.
That no laws of physics are violated and both outcomes are possible but only one outcome at a time can occur because the effect (head or tails) are mutually exclusive of each other.
You can't get heads and tails.
When more than one outcome is possible we have to use probability, randomness, chance to model things. — m-theory
If you find a coin on the street facing heads down...that violates no laws of physics.
If it had been heads up instead...that too would violate no laws.
Both outcomes are physically possible...just not at the same time. — m-theory
This is incoherent to me. You cannot look at the past, and talk about the chance of an event occurring, because events don't occur in the past, they occur at the present. In the past, events have already occurred. I am not talking about Laplace's demon, I am simply making a proper distinction between future and past.So concerning the past the probability that an event occurs does not have to be different it will remain the same. — m-theory
In evolution when the term random is used it is often in reference to some chemical stochastic process.A stochastic event or system is one that is unpredictable because of a random variable. The word stochastic comes from the Greek στόχος (stokhos, "aim"). It occurs in various professional and academic fields.
Researchers use the term stochastic systems to describe the physical systems in which the values of parameters, measurements, expected input, and disturbances are uncertain. In probability theory, a purely stochastic system is one whose state is randomly determined, having a random probability distribution or pattern that may be analyzed statistically but may not be predicted precisely. In this regard, it can be classified as non-deterministic (i.e., "random") so that the subsequent state of the system is determined probabilistically. Any system or process that must be analyzed using probability theory is at least partly stochastic.[1][2] Stochastic systems and processes play a fundamental role in mathematical models of phenomena in many fields of science, engineering, finance, and economics.
Now let's look at a past event. You have found a coin on the street, in the heads position. There is no chance that it could have been found at that time and place in the tails position, because it was in the heads position. The fact that it was in the heads position excludes the chance (possibility) that it was in the tails position. — Metaphysician Undercover
If the universe ultimately is random or deterministic may well be an unanswerable question in science. — m-theory
It seems to me you believe that probability only applies to some future event...that is not strictly true in modern physics. — m-theory
Why would I want to do that, and support such an incoherent myth? I already know the truth, that a past event is what it is, and that it is impossible to change it. Until someone demonstrates that a past event can be changed, I'll continue to believe the inductive logic which says that it cannot. Therefore, there is no possibility that a past event could be otherwise. Once the accident happens, or whatever happens in the world happens, there is no possibility of reversing this. There is of course the possibility that the event which occurred, could be other than the way I describe it, or remember it, But this is a different sort of possibility altogether.There is plenty of source material you could review to get a better grasp of modern physics and the role probability plays. — m-theory
So the myth of chance permeates through physics as well as biology. There is a chance that past events could be changed?I don't see how I can further your understanding except to say that you are making classical arguments that do not lend themselves well to modern understanding of how physics work. — m-theory
Look, the passage here refers to a state, and a subsequent state which is predicted, determined probabilistically. It doesn't at all refer to a past state which is determined probabilistically. Why do you insist that physics treats past events, events which have already occurred, as probabilistic?In probability theory, a purely stochastic system is one whose state is randomly determined, having a random probability distribution or pattern that may be analyzed statistically but may not be predicted precisely. In this regard, it can be classified as non-deterministic (i.e., "random") so that the subsequent state of the system is determined probabilistically
The reason why I haven't given consideration to the perspective you describe, is that I haven't found a way to make sense of it yet. And it's not that I'm not tying. What I want, is a way to understand what you mean when you say that you believe "randomness is very real". As I explained, I can see how the outcome of a future event, like tossing a coin, could be said to be random, or chance. Further, I can understand that if an event like this occurred in the past, at that time, prior to the event occurring, the outcome of such a proposed event could have been said to be random. But when we look back, now, at the past event, there is no randomness. The coin was tossed, and there was a particular outcome. The randomness, or chance element of the event has been removed by the passing of time. Therefore randomness, or chance, is only something which exists at the present. And, it exists only in relation to the future, not in relation to the past.You may well be right to argue your point...but what I was hoping to impress upon is that you are arguing an interpretation of current understanding and not indisputable facts of reality as we currently understand it.
If the universe ultimately is random or deterministic may well be an unanswerable question in science.
I happen to believe randomness is very real and is fundamental to our universe, that would mean that evolution would be truly random as well, however I do realize that this is interpretation and not fact.
I cannot prove beyond all reasonable doubt that it is true. — m-theory
If that were so, possibility would be incoherent because only what happened could occur. — TheWillowOfDarkness
No matter what I end rolling, it is true the other five number were possible-- that's why one of the many numbers I rolled was a possible outcome, rather than the necessary one. I had chance to roll other numbers, I just didn't. — TheWillowOfDarkness
Free will is actually one of the best examples to demonstrate this. If we were to believe your account of possibility, no-one could make a choice between two possible options. What they end up doing would be the only action the could have taken, as them acting in a different way, in that time and space, would exclude any possibility the might have acted otherwise.
For free will to function, possible options have to be available, no matter what someone ends up doing. That's how we can say the murder had a choice about whether to kill someone. Despite the fact they acted one way, it was possible they could have acted otherwise. Other outcomes at points in space and time have to be possible if free will is to be coherent. — TheWillowOfDarkness
That the reason for something is unknown is distinctly different from there being no reason for that thing. When the reason for something is unknown, it is illogical to proceed to the conclusion that there is no reason for that thing, simply because the reason for that thing is unknown. When you consider the possibility of design, then you cannot logically proceed from "the reason for causal relationships is unknown", to "there is no reason for causal relationships".Yet, it is also true there is no reason for any causal relationship. — TheWillowOfDarkness
The past has already changed to become the present???So the myth of chance permeates through physics as well as biology. There is a chance that past events could be changed? — Metaphysician Undercover
Because of the principle of relativity.Why do you insist that physics treats past events, events which have already occurred, as probabilistic? — Metaphysician Undercover
Of course not...humans designed these concepts in order to model reality.Do you think that a random event, or stochastic system, could exist without being designed? — Metaphysician Undercover
Why do you believe the laws of physics for the past are different from the laws of the present and/or future? — m-theory
That might be what you believe, what I believe is that humans designed stochastic systems, and from these they produced the concept that parts of reality consist of random occurrences. Yes, it's true that parts of reality consist of stochastic systems, the parts that humans have designed and produced.Of course not...humans designed these concepts in order to model reality. — m-theory
I take these things very seriously, as you can see, I am tying to understand them. But I think that those who take such things for granted, without properly understanding them, don't take them seriously. That's how myths are propagated, people take things for granted without properly understanding them.It is not my problem if you can't be bothered to take probability, chance, and randomness seriously. — m-theory
Actually, the future has become the past, that's what the passing of time does. We can designate a point in time, such as August 21, 2016, 12:00 noon GMT, and that point in time will change from being in the future, to being in the past, as it changes at the present.I don't know if the past can change or what that means....somehow the past has become the present and I don't see how that is possible without change and I know you can't model it without using randomness. — m-theory
Actually, the future has become the past, that's what the passing of time does. We can designate a point in time, such as August 21, 2016, 12:00 noon GMT, and that point in time will change from being in the future, to being in the past, as it changes at the present.
Once it has become the past, all changes which will occur have already occurred, as they occur at the present, when the future becomes the past. Therefore it is impossible that the past can change. — Metaphysician Undercover
As for your model, which employs randomness, I suggest that the randomness is simply a reflection of your inability to comprehend what it means for the future to become the past (for time to be passing). — Metaphysician Undercover
