Dear Dick, I have overlooked nothing of the sort. What YOU are overlooking is that you are inconsistent – the above "definition of knowledge" is not only inconsistent with the JTB definition of knowledge that you agreed to way back in post #3, it is also inconsistent with your own definition of D.Doctordick said:I don't claim it; I simply define the future to be "what I do not 'know'". C is what I know which is absolutely true. What I think I know is defined to be the set C + D. I have been very careful never to even allude to the idea that we can tell the difference between C and D. Somehow you simply seem to overlook that fact.
Under JTB, I can know things about the future – but in post #1 you are quoted as claiming :
If you now have a different definition of knowledge, perhaps you could explain what it is so that we stop going round in circles?Doctordick said:the future is completely unknown
moving finger said:If so, may I ask you to define just what you do mean by “knowledge”?
Doctordick said:I simply define it to be C + D.
Doctordick said:D represents everything one thinks is true which may not be true.
This does not say that D cannot contain propositions about the future. If I can think it is true that the sun will rise tomorrow (which in my case I do), then this is clearly within D. But this is a proposition about the future. Therefore if you define knowledge to be C + D (which you do) then one can know things about the future, which is yet again inconsistent with both of your your claims :
Doctordick said:the future is completely unknown
And
Doctordick said:I simply define the future to be "what I do not 'know'"
Doctordick said:Ok, then tell me how you would like to adjust in my proposed goal, which is, by the way, find a mechanism for constraining explanations to be consistent with what is known.
I have simply stated, in post #12, that I believe your point (4) should read :
moving finger said:(4) The perfect explanation can not change as more information is added. That is, the "perfect model" must be valid at all times past, present and future. But in striving to arrive at this “perfect model” we may need to pass through many “imperfect models”.
Which in post #15 you seemed to take exception to, claiming that the original point (4) was not yours anyway.
Agreed. This shows that all the essential components (information, explanation, expectations, meaner) are essential to derive any meaning, because meaning is derived from the inter-relationships between the components – each component in isolation has no meaning. “Explanation” is no more fundamental in this than any of the other essential components.Doctordick said:I have defined an explanation to be method of obtaining expectations from given known information. The "meaner" certainly has some expectations and one would assume those expectations are based on something: so an explanation is a way (at least modeling the procedure of the "meaner") of getting from "what those expectations are based on" to the expectations of the "meaner".
Of course – we cannot derive any expectations without assumptions. In the example of the arbitrary measurement of position that you gave in post #3, one cannot arrive at any expectations of velocity or momentum or position unless and until one defines a coordinate system against which to measure such quantities. But in absence of any other physical reference point, the definition of this coordinate system is arbitrary – there IS no preferred frame of reference. And if two non-communicating people make their independent measurements on the particle, there is no a priori reason to expect that their results will be correlated in any way at all.Doctordick said:No, the central issue is the existence of ignorance and the fact that the problem cannot be solved without assuming the "absence of ignorance on that particular issue". The need to make that assumption has very real consequences.
This, however, imho does not (as you seem to claim in Post #3) then lead to a derivation of the law of “conservation of momentum”.
This may indeed be true, but I’m sorry that I don’t understand your maths enough to agree or disagree.Doctordick said:There exists no internally self consistent explanation of any possible world which cannot be interpreted (when taken in total, including the definitions of all concepts used in that explanation) as satisfying my fundamental equation.
I view “creation assumptions” as another term for “boundary conditions” or “premises”Doctordick said:It has nothing to do with the "creation assumptions" of the agent; it has everything to do with creating an internally consistent explanation from a finite amount of information.
Thus you are saying there are no premises in your model, apart from consistency itself?
Best Regards
--would that be a correct understanding of the worth of your equation to my problem ?
