    Knowledge Qm
Click For Summary
The discussion centers on the interpretation of quantum mechanics (QM), emphasizing that QM probabilities reflect states of knowledge similar to classical probabilities. The wave function collapse during measurement is described as a physical phenomenon that transitions knowledge from probabilities to specific outcomes. The conversation highlights the parallels between classical and quantum physics, particularly in how both utilize probability and differential equations. A significant point raised is the nature of knowledge in QM, questioning the existence of a "state of nature" and the implications of this on our understanding of measurements. Ultimately, the dialogue suggests that physics serves as a communication system between nature and observers, reinforcing the idea that knowledge is shaped by our interactions with the universe.

Thank you for your response to my questions. Your concept of PATK is fine with me, of course we must have "potential" to effect before "actual" effect. But perhaps we both error in our quest for truth--I looking to defend primacy of being, you looking for primacy of consciousness (or ability to know)--here for example is an alternative view from someone I admire greatly:

"If you follow your bliss, you put yourself on a kind of track that has been there all the while, waiting for you, and the life that you ought to be living is the one you are living. Wherever you are -- if you are following your bliss, you are enjoying that refreshment, that life within you, all the time".

"Now, I came to this idea of bliss because in Sanskrit, which is the great spiritual language of the world, there are three terms that represent the brink, the jumping-off place to the ocean of transcendence: sat-chit-ananda. The word "Sat" means being. "Chit" means consciousness.
"Ananda" means bliss or rapture. I thought, "I don't know whether my consciousness is proper consciousness or not; I don't know whether what I know of my being is my proper being or not; but I do know where my rapture is. So let me hang on to rapture, and that will bring me both my consciousness and my being. I think it worked".

--Joseph Campbell, The Power of Myth, pp. 113, 120

Good suggestion. That is exactly the place to start. I have given this question some thought when I was having a conversation with Moving Finger at https://www.physicsforums.com/showthread.php?t=64156&page=9
(if you read this, be aware that PNS = Physical Neurological System = biological body).

The conclusion I reached in that discussion was that while qualifying the term 'knowledge' by saying 'certain knowledge' is redundant, it nonetheless emphasizes the question of what knowledge is. Indeed, it raises the question of whether any knowledge can exist at all if it must be certain. How can anyone be certain about anything? I think it is not possible. So what does 'knowledge' mean if the known "facts" are not certain?

I think the only way out of this is to consider knowledge to be characterized on a scale from, say, 0 to 1, where 0 means it isn't knowledge at all, and 1 means certainty. Then "facts" would fall near the upper end of the spectrum even though none would be exactly on the 1. Thus we could have useful and fairly reliable knowledge without requiring certainty. The foundation would be at least as firm as what we build houses on.



I agree. But I would point out that you have qualified 'knowledge' by restricting it to "human knowledge". It leaves open the question of the existence of a knower other than humans which might have a very different basis for knowledge.
There are a few assumptions buried in this claim. First of all, the meaning of 'we' isn't clear. Of course the tacit meaning is the collection of humans involved in this discussion. But in my view, I don't think the perceiver, in the sense of the conscious awareness of the perceptions, is necessarily confined to the brain. So when we talk about what "we perceive" we might be talking about the information that can be reported by a biological body, or we might be talking about some other entity (my PC or PATK) separate and apart from the body.

Another ambiguous term is 'reality'. Since so many people assume that reality consists of nothing more, or beyond, the physical universe, we are left with no term to describe anything that might exist in addition. So, I would suggest saying, what we humans report perceiving is physical reality. I also suspect that what PC perceives via information from a particular brain on a particular world line is largely a portion of physical reality informed by that particular POV. Further, I suspect that PC may perceive things outside of physical reality even though he/she/it might do so via information from a particular brain (say Les Sleeth's) on a particular world line (say during one of Les's meditation sessions). In short, I'd say that reality is much greater than what is conceived by scientists to be the universe.
Amen! (So to speak) I think that happens in spades. In particular, I think any access to non-physical information as reported by humans is always so distorted and unreliable as to be nearly useless. To wit, all the religions of the Earth and the confusion, error, hostility, devastation, and error they have wrought in trying to interpret their respective revelations.
I agree. Science, and in particular mathematics, has set the standard for deriving knowledge from what we can perceive.
I suppose you might be right. But this wild speculation is still a lot of fun. Moreover, I think that at least some progress can be made strictly by using logic and exploring the implications of some unconventional hypotheses. And, as I keep saying, it seems to me that the implications of assuming the existence of only a single consciousness leads to a framework which not only accommodates all the explanations of science, but also all of the mysterious behavior of human beings as well.

Thanks for your thoughts,

Paul
That thread predates me but I have posted a reply.

Certainty is A, if not The, big one. As I understand the meaning of the term "knowledge" certainty is a measure of how well a given fact of reality (knowledge) can be validated in ones own mind. I ascribe knowledge solely to the human existent for the purpose of most philosophical discussion with the following qualification; I know of no other beings with the capacity for validating knowledge although it is entirely possible that other creatures exist in the universe with this capacity. Animals are certainly capable of knowledge on the perceptual level but I doubt they have the ability to validate it epistemologically.
