Re: Weyl on mathematics vs. reality
Hi Roger Clough, My understanding is that qualia are subjective or 1-view, while the realm of science is completely objective (3-view). I agree. A qualia, like the feeling of being convinced, or like the feeling of seeing the color red, is subjective (1p). But now the theory saying that a qualia is 1p, might very well be objective. Science cannot use subjective statements in a theory, but this does not prevent a theory to make statements on subjectivity. If not, you would make a confusion between a level and a meta-level. We can develop objective and even testable statements about subjectivity. For example, with comp, we can decode an 1p-dream from a brain 3p- analysis. This seems to have been partially tested: http://www.scientificamerican.com/article.cfm?id=scientists-read-dreamsWT.mc_id=SA_WR_20121024 Bruno Roger Clough, rclo...@verizon.net 11/6/2012 Forever is a long time, especially near the end. -Woody Allen - Receiving the following content - From: Bruno Marchal Receiver: everything-list Time: 2012-11-06, 08:49:43 Subject: Re: Weyl on mathematics vs. reality On 05 Nov 2012, at 20:03, Roger Clough wrote: Hi meekerdb Love is a qualia and science cannot touch qualia.

That seems like an impossible hypothesis. Usually when one talks about having a model it is a model that one created or someone else created and the correspondence with whatever is modeled is part of the creation of the model. If you were simply presented with a model of all reality and you didn't know who created this model so that you could ask them how it corresponded to the thing modeled then you would be just like a scientist faced with nature and you would proceed by creating a model of the model in terms you understood. What you say about a historical development is exactly what Van Fraassen offers as a part of a solution to the coordination problem. What exactly is 'coordination' and why is it a problem? An analogy would be using a map. One needs for example to locate oneself in a map. This could be generalized. Let us consider how an engineer for example uses Maxwell equations. An engineer starts with a design. This design could be described by Maxwell equations but one needs an engineer to suggest the design. Maxwell equations on their own are not enough. Yet, even after the theory has been developed (let us imagine that the science has included in its model the dark energy, the dark matter and have found a way to make GR and QM compatible), one needs to take a decision what a particular part of the theory is necessary to drive a particular innovation. Even a complete scientific theory will not do it by itself. In this sense, it will be still incomplete. I don't understand the problem; are you simply saying the model of reality is not reality itself? That seems rather trivial. In a way. A scientific model is after all a representation. And a representation is p. 21 “Z uses X to depict Y as F” Hence even a complete scientific theory does not contain Z uses. This remains somehow outside of even a complete Theory of Everything. In a way it is trivial, I agree. Yet, it seems for example Hawking in his Grand Design does not agree with such a trivial observation.

Re: Re: Weyl on mathematics vs. reality
Hi Alberto G. Corona The only way to know reality is subjectively, just as Descartes found. He threw everything out until all he could know for sure was that he could think. Reality is what is happening now, which is what we can only know subjectively, from inside, by aquaintance. We cannot know now or reality descriptively from any theory, only by subjective acquaintance.
