I suppose you could say there are 2 sets of "laws" for everything. The way things actually are would be Law Set #1, and our descriptions of how we think things are would be Law Set #2. The laws in Set #2 would only equal the laws in Set #1 when/if we have absolute and perfect knowledge of any single phenomenon that the law covers. Perhaps this will happen some day. <strong> Quote:
The prescriptivist however wants to make Law Set #2 automatically the same as Law Set #1. They've yet to justify such a position. I'd challenge anyone to prove that our understanding of reality is "inviolate". When we talk about the laws in our science books, we're talking about our understanding. |

excreationist -on road-trip- ,
Thanks for that article by Daniel Dennett and Christopher Taylor. Although the pictures used to represent logical connectives didn’t load, I found the text tremendously helpful in clarifying my thinking. I encourage others to read the article itself because it is an elucidating synthesis of concepts. However, for those who haven’t the time/patience/inclination to read the article, I think it’s worthwhile to highlight one particular issue: counterfactuals. Human beings are experts at determining what kinds of occurrences and choices are “possible” simply because we are experts at: (1)Determining how various factors influence the relative likelihood of an effect or set of effects. (2)Modeling possible consequences of these effects. I use the qualifiers “relative” and “possible” because human beings do not live in rigid microdomains. We have to be able to adapt with imperfect knowledge under suboptimal conditions. This is true, especially true, in predicting our own thoughts and behavior. One way we deal with uncertainty is by modeling several likely courses of action that we (or someone else) can take. When we do this, we say we are imagining counterfactuals or different possible choices. Interestingly, the very results we derive from examining different courses of action can change our course of action. The very ability to imagine choice gives us more choices. The world can be understood, at least approximately, in terms of relatively simple rules acting upon matter. (For our purposes when I say “physics” I mean primarily our intuitive patchwork of understanding about how things in general work. This notion extends beyond physical laws to include theories like human motivation.) This gives human beings the capacity to imagine arrangements of matter that do not actually exist and to modify these arrangements using the rules of physics that can be shown to exist. A clear advantage of separating states from the rules by which they evolve is that we can develop a more sophisticated understanding of the rules themselves. As Dennett and Taylor say, “Looking at precisely the same case, again and again, is utterly uninformative, but looking at similar cases is in fact diagnostic.” The degree to which counterfactuals or experiments are effectively diagnostic depends in turn upon our understanding of how the similarities and differences between the situations are important. There is no general method for performing this task but humans are clearly apt at this task. “Our theories,” as Popper said, “die in our stead.” Madmax, Quote:

1)Eternal life is the OPPOSITE of mortality. 2)Mortality is SMALLER than eternal life. Therefore 3) We know about mortality from immortality. therefore 1a)Immortality is real. therefore 2a)Mortality is NOT real therefore 3a)Immortal people don't die.(Of course immortal people don't die, there is no THEREFORE.) Good mother nature, I don't even know where to begin. Do you fail to see what is wrong with this argument? Don't you know that nothing follows from anything else. This is just an unconnected string of assertions, it's totally irrational. Quote:

These are some definitions for selection: "Singled out in preference" "Careful or refined in making selections; discriminating" Also, I'll repeat an example to help explain what a selection is: Quote:
It would evaluate these options according to that criteria and tell you about which option is the answer. This would be its "selection". To evaluate the options involves a computer iterating through the list and keeping some values in its short term memory. A rock doesn't do this!! It doesn't iterate through a list of options to evaluate them, then return its selected option!!! It just acts using reflexes - it hits something then is deflected, etc. Quote:
It didn't evaluate all of the paths!!! A single path involves many different bumps. Before the rock goes down the path it doesn't evaluate all the potential paths, like a chess computer does and determine the optimal path to take and set about going there!! Do you think a rock looks into the future (like a chess computer does - it can check a few moves into the future) and it searches through all of its possible paths which one is the "correct" one? No, it doesn't predict the future at all - it is just blindly thrown around. It's like a chess computer that doesn't try and look into the future - one that just has simple knee-jerk reactions. Quote:
Quote:
e.g. Say the problem was to find the second highest number in a list: 1) 3 2) 7 3) 8 4) 6 The answer is option 2: 7. For a computer to work this out, it would have to check every number in the list, and find the highest number, then the second highest. The simplest way to check through the list is sequentially although you could do it backwards or randomly. In the short-term memory, I'll use these variables: CurrentIndex, Highest, HighestIndex, SecHighest, SecHighestIndex. All of them initially equal n/a. First we'll set CurrentIndex to 1 and look at the first option: 3. This is the highest number, so Highest = 3. HighestIndex = 1. Then check next option: (7) CurrentIndex = 2 7 is larget than Highest (3) so Highest = 7, HighestIndex = 2, SecHighest = 3, SecHighestIndex = 1. I hope you aren't too confused... Then check next option: (8) CurrentIndex = 3 8 is larget than Highest (7) so Highest = 8, HighestIndex = 3, SecHighest = 7, SecHighestIndex = 2. Then check next option: (6) CurrentIndex = 4 6 isn't largest than SecHighest or Highest, so they stay the same. Anyway, do you see a difference between how that works and how a rock works? That involved 5 temporary variables that could "freely" change their values and be compared with the other values. So they could be reused many times. But with rocks, they tend to just run out of momentum after a while and just stop moving. Computer programs on the other hand, can just go in "loops" where a process just repeats lots of times, then it suddenly halts. Rocks don't just suddenly halt when their calculations are complete. They just gradually lose momentum and come to a standstill. Quote:

Saying that there is no free will or truly free choices doesn't mean that selections and decisions are impossible. You are the one who is saying this, trying to put words into the mouths of determinists. You are the one who is saying that the words "selection" or "decision" are only meaningful if there is free will. But it depends on the definitions of these words. And other people can have different definitions of words than you do. So it may be true according to your definitions of those words, but not ours. Quote:
Anyway, those situations can be described in other ways as well, and so can human behaviour and emotions. Quote:

I am not going to delve too much into the old church dogma about eschatology namely Heaven and Hell, as I have given up on that since puberty.
I feel before one asks any questions about immortality/eternal life and mortality/temporal life you have to consider how one emerged into this world in the first place. Arguing that eternal life is the opposite to temporal life is rather like stating that infinity is the opposite to #1 or that the #1 is the opposite to the infinitesimal. I prefer to take it to the two extremes, the infinite is the opposite to the infinitesimal which is the two scalar opposites. Now just assume you have never been born in the first place. That would give you an infinitesimal length of time in which you existed and if you were immortal then that would be an infinite length of time. Just the mere fact that you exist is infinitely greater than not existing at all. I felt that not existing at all, since I had not existed for approximately 10 to 15 billion years since time began should be the norm. And when you die, it would be a return to that natural status quo. Your existence as this moment should be an extremely rare exception to the rule, as there are far more ways of not existing than existing. Well I about to toss a lot of that old dogma out the window. We can never possibly be aware of any condition in which we do not exist like as a skeleton or an pre-fertilized egg/sperm partnership. In is only through the emergence of complex structures like the human brain which endows us with us sense of time can we be aware of our existence. And since the universe is full of such self organizing structures, it is not beyond the realms of possibility that we will emerge somewhere else, with sensation of time and a feeling that we are once again ego-centered to one particular place and time in the universe. Just like you feel like you are now. So far from personal existence being a exception to the rule, it is the norm. As it is so necessary for a perception of time. crocodile deathroll Quote:

The HD would argue that the whole computer “selection” process is simply a law based progression of pattern matching. Inputs #1-7 direct that function #26 (for example) gets executed. The function executes and based on Inputs #10 and #11 spits out some programmed output because a pattern is found and matched up. The “computer” doesn’t really make a choice because it is not a cohesive unit. No part of a computer is “aware” of the consequences nor is there any part that cares about the results. The inputs come in and the result is spit out - period. With this view the computer isn’t really any different than a rock. In the case of the rock, the laws of physics are what would do the selecting of how the rock got down the hill. The same would be the case with the computer even though it may have more variables. As I think about it, I think the HD would say we’re just pattern selecting computers. We don’t make choices, we have no volition, we just spit out output based on input. <strong> Quote:
In comparison, the rock may not do any selecting of its path down the hill, but the laws of physics do determine the path it will take. That path is set and cannot be changed. The HD will argue that we are the same under a naturalistic view of reality. <strong> Quote:

Of couse they would agree that there are genuine choices that humans make. Their argument is that a “soul” is necessary for this to occur and a God is needed to make it all happen.. A deterministic universe where Naturalism is true, doesn’t cut it in their view. <strong> Quote:

That example of selection I gave involved comparisons e.g. "is 6 greater than 8" and assignments where a variable is given a specific variable. It doesn't actually use any pattern matching. Eliza and similar programs do though. Quote:

A rock doesn't do this. Are you saying that it does, or are you saying that a HD would say that it does. I don't care what HD's think. Quote:

e.g. if x+4 = 6, x = 2. Or (4+5)*2 = 18. That's called evaluating an expression. Computers can do that. Although they do it like this: 10001000 + 00000001 = 10001001. Quote:

As for the theists who argue that the naturalistic worldview necessitates a hard deterministic position, they are of course attempting to provide arguments for making the theistic position more reasonable than the atheistic position. While they don't believe the position themselves, they argue that it is an unavoidable conclusion if naturalism is true. Since its clear to me you've never debated such issues with these types of theists, unless you have something constructive to add, I probably won't be responding to any more of your posts. I don't find being called a liar constructive or worth my time to respond to. |

OK to weigh in here again...
I think the point here is that "choice" is just an artificial human definition. To those that invented the word, it didn't seem like rocks made choices, therefore they didn't. It seems like we do, therefore we do. According to the actual meaning of the word, computers do make choices. Objectively speaking, and without arbitrary distinctions, a rock and a computer and a human all act in the exact same way in that they all are a part of nature and follow laws of cause and effect. If you want to get technical, and it seems you do, I don't think there is any non-arbitrary way to set the limits on what is a 'choice'. This seems to upset you greatly and i'm not sure why. Also, the knowledge that the laws of nature are descriptive rather than prescriptive might be useful if we were debating the practicality of predicting human choices, but we're not. We're talking about it in principle, and I don't think that this distinction makes any difference. Whether or not our laws of physics are 87% accurate or 100% accurate doesn't matter, in theory they could certainly be 100% accurate and human choices would then be 100% predictable, again barring random quantum fluctuations and such. devilnaut This seems very simple, yet I have a feeling this post will get very convoluted very soon..
