PGC One example that proves me wrong nicely and shows we can do without conveniently ignoring each other, even if we share similar lines of work: Little excursion: The relation between Gustav Mahler and Arnold Schönberg. In short brute form: Mahler championed the classical world, while Schönberg started to experiment with 12 tone music of 20th century. On many levels, one could think this is a parallel to the encounter of Einstein and Bohr, classicism versus quantum simultaneity, ancient Hellenic forms versus brave new world of incomprehensible peculiarities, God vs. a game of chance playing for truth. After a disastrous first dinner (the kind where Schönberg terminated the evening meal he was invited to at the Mahler House by storming out into the Vienna streets, after talking shop had become a bit too serious after some glasses of wine), Mahler would not only reverse his view on Schönberg's character, but in exemplary form simply acknowledge: I don't really understand what he does, but my ears are growing old. He put everything where his mouth and songs were: Mahler would give Schönberg references as Musikdireketor in Vienna, help Schönberg's music get played/published, even insist with public verbal reprimand that the snobby Vienna elite stop screeching their chairs on the floor during a Schönberg performance, get physically involved in throwing out a rabble-rouser at another performance, and even financially support the young Schönberg. Mahler didn't get Schönberg's music, but he gave the provocateur that questioned the entire musical legacy he stood for and represented, benefit of the doubt. Imagine Einstein doing this for Bohr. In music however, Schönberg spearheading the new paradigm and school of thought would not stop him from becoming one of Mahler's most adoring fans which is evident from letters or his reaction to Mahler's 8th Symphony. There are countless other examples in which people rectify mistakes and get over violent/competitive histories. In the end Mahler's heart shines through the histories, the technical quagmires, and differing musical theologies and theories between the two. No need for this competitive posing around. It can be done. And where there are strong women and men, it is. PGC It's not really that profound methinks, though I enjoy greatly your detailing of the fascinating love/hate between Gus and Arnie.

Up until this moment, I had only been aware of the non Jewish kind of competitiveness and saw parallels also between Bohr and Everett, to take another example of these difficult kinds of relations. My point being that what seem like huge gulfs technically, can turn out to be Einstein spooking Bohr, or Mahler respecting Schönberg, or Bohr having none of Everett. In all cases you can have fruitful continuations in longer run, therefore the subject is trickier and as profound as it gets imho; not least because it's also bears on theological question.

Kuhn, revolutions, etc. If you read the book (attached 1st of 2 sections) you'll find the Kuhnian idea of revolutions is, in ch 13 properly contextualised (Extracts below). If ever there was a revolution, this one _we are in_ now is equal to that of the 1st, which is the enlightenment (rise of empiricism) and caused the industrial revolution. The rest of the story of change is that of a power-law (quoted below from the book). Yes, i agree with you . the 'amount' of change is a hard thing to define and Kuhn's take was an outlier... Had he been aware of power law physics history may have been different. Godel. While there is a Godellian take on the 'structure aspect science '/'appearance-aspect science' relationship, it is not a key insight into the implementation of the observer. Just because Godel put self-reference into maths does not entail this is literally speaking to the process of subjective experience (scientific observation) implemented by an actual real world made of some real structural primitive - that being explained by the proposed new science framework, Dual Aspect Science. Am preparing a paper on the Godellian interpretation of cellular automata. Mathematics is merely a description of nature.

Please read it. I mention Godel p254 in relation to formal systems. Zero philosophy. This is an empirical proposition. Philosophy is discarded as irrelevant early in the book. The choice of assumption is always philosophical, even theological if there is an ontological commitment. And you do assumes (explicitly?) nature. This makes your approach non computationalist. What is non computational in nature. Also, you are right that math describes nature and nature is not made of math (which is meaningless), but this does not entail the existence of a nature which would not be describable as an aspect of the mathematical reality.

Bruno Regards, Colin P285/286 That said, the way paradigms were viewed after Kuhn's Structure has been largely re-engineered by subsequent reviews, including some by Kuhn. Post 1962, there was a large discourse (it still continues! E.g. [Weinert, 2013]) that disagreed that the evidence Kuhn presented supported the idea of 'sudden shift' to an incommensurable paradigm. All manner of re-characterisation of scientific change has subsequently added nothing particularly clarifying. Even if it did clarify, like everything else in this area of philosophy, it is practically irrelevant to scientists, who remain unaware of it and even if they were aware it would change nothing. The answer to this, from a dynamical systems perspective, is that changes in the statements made by scientists have what would be called, by scientists, a 'power law' seismology

Gödel showed that you cannot have an effective (checkable theory) which is both consistent and complete. But you can have a theory consistent and complete. It will just be non effective. The theorems will not be recursively enumerable, and you will be unable to check mechanically if a proof is valid, or if a true proposition is provable. A simple example is just the set of all true arithmetical propositions. Only a logician can call that a theory. usually the theories have to be effective to be considered as genuine theory. usually, the non effective structure related to truth is called a model in logic (but the set of sentences true in that model is also called theory by logicians, but those are most of the time non effective (non Recursively enumerable).

Sure, there are examples of great selflessness in the name of stepping forward together too, but this is rather exceptional. PGC One example that proves me wrong nicely and shows we can do without conveniently ignoring each other, even if we share similar lines of work: Little excursion: The relation between Gustav Mahler and Arnold Schönberg. In short brute form: Mahler championed the classical world, while Schönberg started to experiment with 12 tone music of 20th century. On many levels, one could think this is a parallel to the encounter of Einstein and Bohr, classicism versus quantum simultaneity, ancient Hellenic forms versus brave new world of incomprehensible peculiarities, God vs. a game of chance playing for truth. After a disastrous first dinner (the kind where Schönberg terminated the evening meal he was invited to at the Mahler House by storming out into the Vienna streets, after talking shop had become a bit too serious after some glasses of wine), Mahler would not only reverse his view on Schönberg's character, but in exemplary form simply acknowledge: I don't really understand what he does, but my ears are growing old. He put everything where his mouth and songs were: Mahler would give Schönberg references as Musikdireketor in Vienna, help Schönberg's music get played/published, even insist with public verbal reprimand that the snobby Vienna elite stop screeching their chairs on the floor during a Schönberg performance, get physically involved in throwing out a rabble-rouser at another performance, and even financially support the young Schönberg. Mahler didn't get Schönberg's music, but he gave the provocateur that questioned the entire musical legacy he stood for and represented, benefit of the doubt. Imagine Einstein doing this for Bohr. In music however, Schönberg spearheading the new paradigm and school of thought would not stop him from becoming one of Mahler's most adoring fans which is evident from letters or his reaction to Mahler's 8th Symphony. There are countless other examples in which people rectify mistakes and get over violent/competitive histories. In the end Mahler's heart shines through the histories, the technical quagmires, and differing musical theologies and theories between the two. No need for this competitive posing around. It can be done. And where there are strong women and men, it is. PGC -- You received this message because you are subscribed to the Google Groups Everything List group.
