Re: What can we know of reality?
I feel like minimalism is an important product of epistemology. Meaning that in order to be able to understand our surroundings, we must assign to the definitions of ideas the normal context in which they appear.
It is a more general form of what makes science, math and even simple logic useful tools.
Science deals with objects and finding all properties of those objects so that we can better determine how they interact with other things. Math and simple logic deal with simple ideas that retain a minimalist definition because it is obvious to append them with additional information would change their essence.
Ideas like honesty and even infinity are different because they complex enough that people can begin to append additional information on to them.
If I define honesty as "what people aren't when they knowingly fail to provide correct and useful information that someone needs to act upon".
When you collect a large number of such contextual definitions, philosophical matters become trivial and as precise as mathematics.
According to this reasoning, I wouldn't spend time reading a thread where philosophical issues were being referred to metaphorically with all kinds of made up formulas etc...
I am not writing this to be antagonistic. I don't like it when people give others the idea that philosophy is some necessarily arcane investigation that all but the most intellectual people are barred from. It isn't. It is something that everyone needs to study and understand so that the efficiency of the human race can be increased.

Yes, definitely.

And in terms of our worldview, whatever math you use to describe reality, that math is describing the behaviour of some elements that you have decided to tack with identity. The problem being, we did not begin science with a set of "objects" whose behaviour we are just trying to probe. Instead, we decide what constitutes an "object" (or any defined entity like "space" or "time"), the large deciding factor in these definitions being "what makes it simple to understand/predict the behaviour of reality"
I mentioned space and time; notice that in most cases that math is describing the behaviour of those "sensible things" in some "space" (whose properties/essence you defined), and in some "time" (also that you defined). As a related note, it should be clear to see that there's no point in defending some arbitrarily chosen ontological take on spacetime, just because it happens to seem particularly aesthetical or elegant together with the rest of one's worldview.

Well, a lot of craziness ensues when people have defined some specific semantics on concepts like "good and evil" or "freedom", and then try to force their view as the true and correct one. Anything you say about such concepts might make a perfect sense inside your worldview, like good and evil make perfect sense if one believes there is a god who decides who goes to heaven and who goes to hell (or some other cosmic justice). But then it is once again plain to see that a lot of "arbitrary" assumptions have been made before we ended up with those definitions for "good" and "evil". Relevant as this may be, it is leading us away from the core of the topic...

The formulas are there just to extend our logical abilities. A mere tool. Like the formula for quadratic equation.

Re: What can we know of reality?
God it was nice to hear from you again Annsi; your mind is so clear and open you are a wonder to behold. And both my wife and I loved that “Verizon Wireless Has Trouble With Math video. Although my work is admittedly much more complex than that fellows problem, I have, on many occasions, run into exactly the same kind of difficulty he had. Whenever I have actually gone to show the solutions to my equations, everyone (so far) uses distorted interpretations of my definitions (distortions expressed in their personal picture of reality: i.e., very akin to that .02 cents is the same as .02 dollars thing) to bring all discussion back to those definitions or simply contend that I am wrong. I distinctly have the impression that their true purpose was to find a way in their own head to ignore what I was saying so they wouldn't actually have to question their beliefs. That is exactly the kind of interactions I was referring to when I made the following comment to Buffy:

Or when I refer to that “extra baggage”: i.e., trying to attach meanings to my representations when there are none. You seem to easily understand that issue. Thank you; I appreciate it very much.
Kriminal99, in case you have been wondering,I haven't been ignoring you; I simply find it quite obvious that you don't understand the issue of interest in this thread “What can we know of reality”. There is a problem here which everyone (save Anssi) seems determined to ignore. For example,
Quote:

You cannot so define honesty without first defining the words, "what”, “people”, “aren't”, “when”, “they”, “knowingly”, “fail”, “to”, “provide”, “correct”, “and”, “useful”, “information”, “that”, “someone”, “needs”, “to”, “act” and “ upon". Until I understand what you mean by those words, your definition is simply: honesty is “word #1”+ “word #2”+ “word #3”+ “word #4”+ “word #5”+ “word #6”+ “word #7”+ “word #8”+ “word #9”+ “word #10”+ “word #11”+ “word #12”+ “word #13”+ “word #14”+ “word #15”+ “word #16”+ “word #17”+ “word #18” + “word #19”.
The actual numbers I attach to those words is of utterly no significance. I could just as well have said: honesty is “word #25”+ “word #3303”+ “word #4399”+ “word #24”+ “word #7867”+ “word #2124”+ “word #675”+ “word #2”+ “word #345”+ “word #215”+ “word #2739”+ “word #2237”+ “word #10233”+ “word #2”+ “word #754”+ “word #390”+ “word #287”+ “word #5672” + “word #3490”. And, since I wouldn't know what you meant by the word “honesty” until after I understood your definition, I could simply express the information you intended to express in the above sentence as “word #8675” equals “word #25”+ “word #3303”+ “word #4399”+ “word #24”+ “word #7867”+ “word #2124”+ “word #675”+ “word #2”+ “word #345”+ “word #215”+ “word #2739”+ “word #2237”+ “word #10233”+ “word #2”+ “word #754”+ “word #390”+ “word #287”+ “word #5672” + “word #3490”.
In order to understand what you meant I would have to interpret a great number of very similar expressions (a sufficient number to understand the English language). Every year, millions upon millions of children manage to decipher that kind of information in only a period of a few short years (apparently coming up with very similar conclusions). That means the problem is solvable! And, the creation of AI will depend very seriously on being able to solve that exact problem. I am discussing inherent constraints on that problem expressed in a manner which does not presume your current answer (at time t) is correct but demanding that your current answer (at any given time t) is “flaw-free” (a rather different constraint). I use mathematics because it is the most unambiguous language available to me and we need a language to communicate. To quote Richard Feynman, “mathematics is the distilled essence of logic.” It is very nice that we possess such a language, limited as it may be.
That brings up another issue which I call “the power of ambiguity”. (See my post to saviourmachine February first 2005.)

One very significant aspect of that ambiguity is that it prevents communication.
One of the excellent consequences of preventing communication is the fact that it is impossible to communicate beliefs from one generation to another. Misunderstandings will invariably occur and, in an attempt to make sense of what they think the previous generation is saying, new unique perspectives will arise. Without that ambiguity I suspect intellectual advancement would soon cease.

This is the very crux of my presentation; I am presenting a very small set of definitions (things which can be defined within any information set without saying word one about what that information expresses) and, from that set of definitions coming up with a mathematical tool capable of extending some rather simple logic to an almost infinite set of references. That's it, there is no more and there is nothing to “understand” except the problem itself.

Again, Anssi has hit the veritable nail on the head! He is a very bright fellow; how about giving him a little help with the mathematics.
And, Buffy, I can't give you any examples because I don't know how to solve the problem of understanding reality. Nevertheless, that equation imposes some very interesting constraints on the possible relationships which can exist; but we can't talk about them until we can solve the equation and I am not going to start down that road until I at least feel that you understand the difference between an undefined and a defined structure and the constraints being imposed by that equation. The concept is actually no more complex than the difference between .0002 dollars and .0002 cents.

Doctordick,
You obviously don't know what I am talking about : you have no idea how *useful* your last several posts have been *because* you have been forced into applying a few "examples." I'd urge you to do two things: - Go back and read your last three posts.
- Think about revising what you appear to define the word "example" as.
Even the most theoretical math does not exist in a vacuum: most mathematicians abhor "applied mathematics," but they do *constantly* relate new concepts to existing ones by example. On the other hand, what you are doing in the next step is most certainly applied mathematics! You are indeed starting with a purely mathematical argument which is fine, but if you want to apply it to "what we know of reality" then mappings--even abstract meta-mappings--to "reality"--or meta-realities, which I know is *really* the point--have to be drawn and justified.
The crux of what Q and I both--I think, and maybe even Anissi--are trying to figure out is whether or not your equation maps onto anything at all, and whether that mapping is valid, even if it is pure logic and math. You have yet to address Q's question of why partial differentials are required, and my ongoing unstated question remains "why must it be zero?"
If this is all just an exercise in throwing around arbitrary formulas, then the answer "why not?" is perfectly valid, but if you're (eventually) go on to the next step of saying "this formula can be made a *valid assumption* in constructing internally consistent worldviews" then you need to start mapping the pieces of your formula on to the next step. If you don't its just a meaning-free arbitrary formula!
To apply this issue onto your thesis: your formula may or may not be consistent with any particular worldview, but it all depends on the  it exists within!
So please *do* think about the examples above and try to work with them: Maybe Q's example is too limited (although quite frankly your response to it was tremendously useful!), but anything you can do to provide analogies will assist us meatheads in "understanding what you're talking about."
I'm learning more about what you're talking about by your dismissive treatment of examples than you can ever imagine!
Recursively yours,
Buffy

Thank you for the response. IMO:
I am not sure what you are referring to when you talk about science defining objects. I am referring to, for example, an apple. Animals have concepts of things like apples, without having a concept of science. An animal or even unscientific human may wonder if he hits an apple from a tree, where will it land.
A minimalist will begin listing properties of apples, and seeking to measure additional properties of apples. Logic is only to be used in conjunction with these ascertained properties. Such a person may weigh an object. They may have, through previous such inquiries determined that certain rules apply even when you switch the object you are working with. Then they will combine these ascertained properties logically to better reason where the object will land.
Minimalism is a more general approach because the same thing can be done with introspective concepts like honesty...
Perhaps you have extracted a response to your arbitrary space time objection. You need not refer to space time to deem my concept of an apple arbitrary. I no doubt define the apple in terms of how I perceive it. If I had a bat's sonar array, or if I had an inverted spectrum, my definition would be different.
Realizing this does not change what I perceive regarding the apple. Trying to redefine apple to meet a new understanding of perception or space time is exactly the type of thing that minimalism is supposed to prevent for the sake of processing efficiency. Rather our understanding of such concepts should just be tacked on to the end of everything else we understand and left there. We can say that if we were a bat and had a sonar array, the same external object (assuming there are external objects) would look different. But an apple is still the colorful yummy fruit in front of us.

Nah I do understand it I promise. In fact I already came up with the solution of how define those words (you don't need the whole language) and how children do it a long time ago. I was hinting at it when I mentioned that one only need accept that the frequency with which something has happened in the past affects the frequency of it occurring in the future... Though I suppose it requires a few other memory storing and fractioning abilities without which we could probalby do nothing but drool. I solved this problem by organizing simplified information, where simplified refers to a specific algorithm that I referred to as minimalism. It turns all further philosophical discussions into math and probably would allow for an AI. All my posts were trying to respond to your arguments.
I had tried to make posts regarding that system before, but I just got banned for repeatedly referring to reality in contradiction to things moderators stated.
Anyways, the way the system works is simple and contradicts what Wittgenstein argued. Witt failed to account for people's perception comparison and pattern recognition abilities.
For illustration I will use <> to encase a perceived memory and &# to denote coincidental perceptions, which have occurred # number of times. | will denote or. Certain simple memory related abilities are assumed to be hard wired, with our automatic ability to perform these tasks as adults for evidence.
If a child sees a room with a book in it, and simultaneously hears the word book, he hasn't learned anything yet but perhaps he stores the memory.
Somewhere in his head is the record:
<Sound of word book> & <Image of a room with a book in it>
The next day he is in a completely different room with a book also laying in front of him. (preferably the same one for simplicity's sake, but not necessarily) The child stores the memory:
<Sound of word book> & <Image of a different enviornment with a book in it>
Then the child simply compares the similar parts of the two images, which just happens to be the book. Then he removes the rest of the images because of the lesser frequency with which they coincide with the word book and is just left with
<Sound of word book> &2 <Image of book>
Of course it might take more than twice, especially if its a different book or the book is being looked at from a much different angle. But with the implied comparison and pattern recognition ability, many factors can be removed through repeated experiences.
Tomorrow someone says "open the book", and the child watches someone do so. Through similar repeated occurrences he removes factors and obtains the association:
<Open the book> &(X>1) <String of images involving someone opening the book>
Later, someone in front of the child asks someone to open a different object which the child has already been able to associate with it's image. A box perhaps. This verb has not changed, and is associated with a animation that is similar to the one the child saw coincide with opening the book. Thus:
<Sound of command "Open the <Book|Box>"> &(X>3) <String of images involving someone opening something>
Now the child has something to associate with the higher level concept object, even if he doesn't do so right away. Specifically what is to be an "object" is something that can be "open the" 'ed. It is a function of what the child has thus far perceived.
Then the child hears someone say, "Grab the book" and then, and watches them do. And then they see someone being told to and grabbing other things .
<"Grab the <object>"> &(X>1) <String of images of someone grabbing an object>
and also
<Verb> & <String of images involving a person doing something>
Mind you not the word verb, but just the underlying concept just as in the case of object. And also:
<"the"> &(X>1) <Word that comes before <object> and <verb>>
And it continues such that every high level concept can be defined as a function of things previously perceived.
Such memory abilities are implied by our ability to consider something like a unicorn, which consists of a horse that has had the horn of a goat appended to its head.

There isn't even enough information there to conclude those ontological elements are numbers. This is exactly what I was talking about when I said, “Your example is chock full of assumptions (presumed valid ontological concepts) which you take no trouble to explicitly list (because the size of such a list would probably be beyond accomplishment)”.

It took me a while to find this useful paragraph in the plethora. What I wanted was for you to DO it, for the numbers and forget about the rest of the spy's universe. You can add anything that's in the story that you consider essential and specify anything else that would be needed, but I wasn't asking you to do what you're making out. It's of no use to me if you tell me to build the  planes, I need to know HOW you build them and then how you get the constraints, in the latest form you put them into, which I'm not yet able to justify. There's no point in asking people to believe the validity of these constraints and accusing them of denial and of fighting you tooth and nail to deny the possibility that “there always exists an interpretation of any flaw-free explanation of reality which will obey your equation" if you don't help us get through the arguments.
I'm not asking you to provide more links to a sequence of long past posts that I have no time to go through. Try to say the essential and don't accuse me of misunderstanding, just try to help me get the details straight. The problem is that we always run into semantic troubles and you don't earnestly throw the bridge, which would be up to you. In the above quote for example I see the discrepancy in what you meant about assumptions and what I understood it to mean, in the English language. You did not mean what you said: “Your example is chock full of assumptions...” but instead that I didn't describe all the spy knows about his entire universe. It's also a semantic discrepancy when you say the model can't be applied to "specific examples" when instead you meant the same as above. When you say:

and the further thing you said to Krim:

Until I understand what you mean by those words, your definition is simply: honesty is “word #1”+ “word #2”+ “word #3”+ “word #4”+ “word #5”+ “word #6”+ “word #7”+ “word #8”+ “word #9”+ “word #10”+ “word #11”+ “word #12”+ “word #13”+ “word #14”+ “word #15”+ “word #16”+ “word #17”+ “word #18” + “word #19”.

I know exactly what you mean and I've been aware of it for a long time, so have other people; I found an amusing example in one of Hofstadter's books where he illustrates the idea with the word "love". He takes a dictionary definition of the word and then replaces even only the most essential words of it with their definitions in the same dictionary and maybe even the next recursion of this process. This results in an entire paragraph, about which he remarks "How romantic!". Obviously there's no point in continuing with further replacements.
When babies are being brought up properly, words are repeated to them while they are being shown simple things, until they start to make associations. I can remember when I was already old enough to speak fairly well but had difficulty understanding the difference between cat and dog when being shown some real live ones running around a yard. I remember figuring that it seemed like cats have rounder heads while dogs have a snout and the dog was maybe a bit larger, then they pointed out to me that dogs bark while cats meow, I was also told about how they differ in when they wave their tails. It was still somewhat confusing to me.
However, when I posted the story, and said all that I said about it, I was using a well known language called English, expecting it to be understood by members of this forum including DoctorDick. I wasn't "making assumptions" I was using words that we all already know the meaning of. I took this great humongous liberty only to make it a humanly possible feat, it wasn't a matter of arrogance on my part. I was only attempting to accomplish the possible, instead of the impossible. My humble apologies.

Yes it is tiresome and I can't waste too much time either, try to throw the bridge instead of expecting it from everyone else, and accusing them of things.
The story with the spy isn't my personal paradigm, it is a fictional story, it may be regarded as existing in a fictitious universe which may even be similar to yours in many respects, compatibly with what the story specifies. Anything the story doesn't specify is a degree of freedom for you. I did not ask you to build the complete "what is, is what is" table for that universe, only one that includes the specified pairs of numbers and whatever you will, that can either be made out from what I (the story's author) posted or compatibly chosen and, if you should so deem, suggest anything specific that should be added (like, perhaps, we would need to know what kind of tubs they bath their feet in). Surely you can do it with some information, as if it were all the available information. Specify what the arbitrary labels are and how the mapping may be chosen. Show me what is consequential, I need to catch up with Anssi before his math skills improve enough to get him even further ahead.
I would further like to clear up a misconception to avoid it adding confusion to the discussion:
Logic does not depend on reality. Mathematics is a type of constructing on logic and certain definitions, in essence choices, and therefore does not depend on reality. Logic and mathematics are not a belief about reality. Whether or not the definitions are chosen to describe some aspect of (a given) reality (in a given universe) is of no whatsoever concern to a mathematician. Reality is of no influence on the validity of mathematics; any valid mathematical construct is valid "in" any reality or universe.

I have done that and I think I understand what you are trying to say; however, I think much of what you are thinking is beside the point.

The problem is that such mappings or even abstract meta-mappings need to rest upon the behavior of solutions to that equation. Without those solutions, I am merely talking about the nature of representation itself. I am sure you have heard of the Ancient tablets with the cuneiform texts. There are apparently two versions referred to as linear A and linear B. One has been translated and, in spite of diligent effort, the other has not. We have a collection of symbols which are not defined and the information content just isn't sufficient to decipher them. Perhaps someone in the future will make a lucky guess and find some pattern within the known data which makes sense and then his (or her) start will lead to other rational interpretations. But meanwhile, it is merely a problem to be analyzed.
Normally, the very first step in analyzing such a problem is to label the various symbols under examination so that they can be easily referred to. The significant fact of interest to me is that the actual label used in such a circumstance is totally immaterial and that fact itself has consequences.

I had thought I had answered both those questions a number of times. I will try to explain it in another way.
I have set things up so that “what is to be explained” is a set of numbers (those arbitrary numerical labels) which are displayed as a set of points in the  plane. I have defined "an explanation" to be a method of obtaining expectations from given known information. Your expectation (which are actually a specific subset of of those numerical labels) can be represented as a probability (a number bounded by zero and one) with which you expect a given specific subset.
Thus it is that the solution (an explanation; that method of obtaining expectations which is in fact the epistemological construct to be discovered) can be seen as a mathematical function: the argument of the function consists of the set of specific labels and the output of the function is the probability that set will appear in a future  plane (the future being defined to be “not part of the given known information”).
Since I want to omit not a single possibility for that “mathematical function”, I represent the “method” via a scalar product of an abstract vector function  which can represent any possible transformation from one set of numbers to another set of numbers (any set of information into a second set of information) and where the transformation into a number bounded by zero and one is an easy thing to define.
Now, the important thing in all this is that the given known information is actually the things being labeled, not the labels themselves. Since it can be represented as a mathematical function of those numerical labels, we know certain symmetries must exist in that representation. In particular we know shift symmetry must be a property of the representation. If we have discovered a solution, ( a method of obtaining expectations from given known information) that method must yield the same result if we were to change all of our numerical labels by simply adding some number a to each and every numerical reference label (the three axes of our representation can be considered independent sets here). The point being that the output of the function is a function of the things being labeled and not actually of the labels themselves. By making the representation a function of the labels, we have introduced the shift symmetry.
To put it another way,
or
Since a can be any number, it should be obvious that
Notice that, in the above, the arguments of  are themselves shown as functions of the shift parameter. Any rudimentary knowledge of partial differentiation should include the fact that the above has to require that
and, adding the fact that  , one is clearly led to the conclusion that
You might be bothered by the fact that the  are discreet numbers and the partials above treat them as continuous variables. This shouldn't be bothersome as no new information (which would add possible new values) can violate any of the steps given. It follows that, in the continuous limit, we should expect the result to be valid. Plus that, it provides about the simplest possible extension of information into unknown regions. Lastly, the above can be done in each of the orthogonal axes of our representation. As to the question, why are these differentials required? I don't see that they are except for the fact that they lead to a convenient way of expressing the constraints required by the existence of that shift symmetry.

I would agree with that 100%. At the moment, it is absolutely nothing more than a meaning-free formula. I don't know that I would use the word “arbitrary” as it is somewhat strongly dependent upon the definitions I have already put forth.

I won't comment on this because I do not understand what you had in mind when you wrote it. My thesis is that there always exist an interpretation of the facts known to me which satisfies my representation. In no way does that make it consistent with “any particular world-view”. It can be no more than an interpretation of what I know of a specific world-view and it rests upon a paradigm which insures that as more information becomes available to me, the new information will not lead to a violation of that interpretation.

The problem here is that any problem which can be solved at all requires such a large base of information that that the actual process required is far beyond anyones physical capability (at least on a conscious level). And I certainly don't regard anyone here as a “meathead”. I am very willing to work on trying to communicate. I think you may find my following response to Q enlightening. If not, I apologize.
Qfwfq, I may have misjudged you. You may be trying to resolve a problem which I have not yet mentioned. I have avoided the issue because, once it is broached, most everyone refuses to take me seriously. I will try and clarify exactly what I have in mind.

The arbitrary labels are “arbitrary labels” and the mapping may be chosen anyway at all. Essentially, nothing is consequential; the consequences are entirely in your epistemological construct (your interpretation of what is going on). It makes utterly no difference what that epistemological construct is, if it is internally consistent, the temporal behavior of the ontological elements can be interpreted such that my equation is a valid constraint.
I suspect you may have noticed that there need be no underlying rules to reality at all: i.e., essentially embedded in my work is the question “what would reality appear to look like if it were absolutely and totally random?”. Most everyone is quite confident that “it certainly wouldn't appear as it does”. I do not know “what it would look like”; however, I do know that any explanation you could develop for it could be interpreted in a way which would guarantee the ontological elements would obey my equation. That leads to the conundrum, “how could I possibly achieve an explanation of a totally random reality. Actually, the answer is quite simple.
Essentially the circumstance implies something very significant: your explanation of reality must actually be a data compression algorithm which, in reality, (to use the word in a slightly differently way) says nothing about reality other than “what is” is, “what is”. Most everyone immediately drops into the “that can't possibly be true” mode when they realize this and want to hear not another word of it. In their opinion, I must be nuts to even consider such a thing: i.e., to make a metaphor, it doesn't even mention the god of science “causality”. I suspect there is not a single professional scientist who would even dream of considering the possibility as his professional standing would immediately vanish were he to do so. The position of the scientific community is that “an absolutely random universe could not have any rules”. The really significant issue here is that I am not talking about reality, I am talking about your interpretation of reality (your explanation of your experiences), quite a different thing. The fact is that it is your interpretation of reality which must have rules and the ”what is”, is “what is” is the only interpretation which exists without rules.

It is valid even if that universe is totally and absolutely random. Nevertheless, such an assertion quite often brings forth nothing except total rejection, quite analogous to that “I burned my math book because it had no mention of God.” Modern science is indeed a religion as they think they understand the universe and believe there cannot be another perspective as successful as theirs.
Just an interesting comment. Many years ago, when the Internet first became available, I ran across a very interesting web site. I have searched for it many times since but have never been able to find it again. I was a mathematical presentation which proved that, for any given pattern of numbers, there existed a number of numbers within which that pattern could not be avoided. This was a long time ago and I didn't really examine his proof carefully so I cannot stand behind it but I think a simple example of what he was talking about could be “two numbers the same distance apart”. If you try to construct such a set of integers where the pattern absolutely does not appear, you will always run into difficulties.
Start with  and  . Then no number which differs from either of them by  or  can be used. (In fact, no pairs which differ by those amounts can be included in the set; there may be subtleties to this extension which have far flung import.) There are still a lot of numbers available so we can add  to our collection. Now no number which differs by  ,  ,  ,  ,  or  can be used. As I said, I do not remember the proof but it seems to me the result was a consequence of the fact that the number of numbers which could not be used expanded much more rapidly than the number of numbers in the collection (every time one number is added, the number of additional numbers to be excluded exceed the total number of numbers already in the set). As I said, I wish I could find that paper so I could examine it carefully (I haven't been able to prove it myself). It is nevertheless quite clear that, with a sufficiently large set of random numbers, the probability that any specific repeated patterns will be found becomes closer and closer to one.
This implies that, even in a totally random universe, patterns will exist in any collection of numerical labels given to those elemental entities if the number of elemental entities is sufficiently large. Considering that ”what is”, is “what is” table (that set of points in my  space) must reflect some  references for  years means that “no recognizable patterns” is a very improbable possibility: i.e.. even a totally random universe will most probably have a great number of recognizable patterns even if no rules are given as to how the mapping is to be chosen. I think this issue will become much clearer if we can get to the solutions of that equation.
And finally, as to expectations, considering the volume of information represented by the past compared to that which constitutes the present, one should certainly understand that the probability that the present will make any significant contribution to any pattern based description of the past, has to be negligibly small: i.e., the best statement of your expectation should be “the patterns I see in the future should look a lot like the patterns I used to describe the past”. This implies a good data compression mechanism is most probability the best representation of the universe possible and is probably the rational which stands behind our view of reality. We notice patterns and mark them with labels and begin to deal, not with the patterns themselves but, with patterns in those names. That is almost the definition of a data compression mechanism.
Now, I have proved that certain constraints must be imposed upon such a solution and that those constraints are embedded in my “fundamental equation”. The issue is, have I sufficiently defended that position that you will take the trouble to look at solutions to that equation without scoffing at the applicability of my constraints?

Well, I suppose I didn't word my post very well and you misunderstood it.
i should have said which are the arbitrary labels, not what. In the spy's case there are some non-arbitrary numbers and I don't see what the arbitrary labels would be. I don't see what you would map those numbers on to and I don't know what the table would be. I'm therefore unable to deduce the validity of your constraints.

I didn't mean to imply that we are defining objects only when we do science, rather we are defining objects in all our attempts to understand anything about reality.
When you perceive that apple, the definition has already been made since you can understand some pattern as an "apple". Note that we don't necessarily do this "defining" consciously.
Think about the avalanche of sensory data that is flowing into your brain. You recognize things like apples, reflections, glares, waves on an ocean, rivers, tornados and all sorts of stable patterns that you have tacked with identity. Your comprehension of reality rests on these "sensible things", and it is the interplay of these things that you draw your predictions from.
But you were not born with the knowledge that these things exist, instead you defined them. I.e. certain spatial/temporal features of your sensory data become tacked with identity so you understand them as the "same thing"; a thing which preserves its identity through "time" and "space".
Whatever behaviour you find from reality will affect how you break it into components. When you see certain familiar behaviour (pattern), you perceive that as an "object X" that you defined.
(btw, this is relevant also to your example about babies learning language. You cannot suppose the baby just knows what constitutes a "word" or that there even are such things as "words". That is part of your worldview)
So I hope this clears up what I mean by us deciding what constitutes an object. For more philosophical aspects of this, take a look at "Ontological perspective" and "Epistemological perspective" at post #34. (really take a look, I spent a lot of time on that one
Let's take a quick look at physics still. Look at the different ontological interpretations of quantum mechanics. They are each a different set of "ontological elements", and they define "space" and "time" differently; they define them exactly the way they need to so to produce correct predictions/expectations for reality. These views are self-coherent but do not mix with one another; one paradigm cannot be investigated from within another paradigm.
Note that we always have multiple valid options as to how to break it into "objects". It may not be trivial, but it can be done. Also note that it certainly seems, that to break reality into components at all is inherent to how our understanding of reality works, not inherent to how reality itself works. I.e. what Kant said. In brief:

So, assuming you understand how I mean the above, you can understand that world seems very much different when seen through different worldviews (that have tacked identities onto different features of the data, including defining space and time differently). Yet they both can have the exact same explanation power; just they work with different terms.
The question is now, is there something that is common to each and every possible (valid) worldview. By valid I mean they do not contain self-conflict. So, how do we express the constraints that arise from the simple fact that each worldview, whatever it may be, needs to be internally coherent. If it contains self-conflict, it cannot be a good description of reality can it?
Now we are moving closer to where Qwfwq is already standing (I think). Onto the next post ->
