It assumes linearity, continuous complex valued linear combinations of states and 
corresponding continuous values of probabilities. Notice I said as we've formulated it.  
I don't have a proof that it would be impossible to formulate a different, but quantum 
like, theory avoiding a continuum.

Sure, but you'd guess that about physical universes too just from observing how rare life

 themselves. 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 
  

It's not really that profound methinks, though I enjoy greatly your detailing 
of the fascinating love/hate between Gus and Arnie. Actually they were a couple 
of Jewish intellectuals competing with each other in the way that Jewish 
intellectuals always have and always will. Competitiveness amongst Jewish 
intellectuals is a lot of what drives science and art. Bohr was not Jewish so 
Niels and Albert simply weren't on the same wavelength.

Apologies. Up until this moment, I had only been aware of the non Jewish

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.

Maybe one for machines. But I'm too lazy to defend the idea or get
competitive about it... PGC

I might, but if I was looking for life-bearing universes in (say) the

even if granted the godlike powers required to do so. I would more likely
start with whether the laws of physics in each universe allow the formation
of a range of elements, whether they make the formation of large scale
structures likely, what complexity of chemical compounds they make
available, etc. I wouldn't look for life in the level 2 multiverse with a

Yes, I agree, this is the problem with this sort of discussion. The
question is whether we can actually reach any meaningful conclusions based

writing technobabble for Star Trek and Doctor Who. I don't know the

of power law physics history may have been different.

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

This is of course the position that science has taken for the past  
few centuries without realising that there was any alternative.  
However, now that Max Tegmark (and of course Bruno) have argued that  
there is an alternative, simply claiming that nature cannot be made  
of maths no longer cuts the mustard. It's true that maths being  
predictive doesn't prove that nature is made of maths because as  
we know, science doesn't set out to prove anything, especially not  
sweeping ontological claims. But it still seems quite possible to  
me, at least, that Max may be onto something, because as he points  
out his theory explains the unreasonable effectiveness of maths in  
physics - so I will be interested to hear some counter arguments  
that explain this effectiveness on a non universe-is-maths basis. So  
far I've seen a bit of handwavium, but generally I've been  
underwhelmed by the alternatives presented to explain this, which  
leaves Max's theory out in front in terms of explanatory power, as  
far as this particular issue is concerned.


Not that there aren't problems with Max's theory, of course. (It's  
mind boggling for a bear of little brain like me to attempt to grasp  
how it could possibly actually work) But it does seem plausible  
enough to deserve decent counter-arguments.


Max ignores the FPI. he seems to (re)discover it in his book, (but he  
knew my work so that is a bit weird, to remain polite), but he still  
does not (like many) take it into account. In fact he has a less wrong  
ontology (with respect to computationalism) but ignore the  
computationalist mind-body problem. It makes both mind and body having  
non mathematical appearance from inside a little clear mathematical  
structure. He gives the correct fundamental role to math, but he is  
still doing physics, and not the math needed to recover physics from  
math.

Basically all mathematiciens having serach for a mathematical  
unification of mathematics, like Church with lambda calculus, or Frege  
with sets, or Curry with combinators have been driven toward  
inconsistent theories. Each time the mathematical reality kicked back  
and called for more modesty. Your view is called conventionalism, and  
in my opinion made unsustainable by Gödel and Co. Even Einstein, a big  
conventionalist in math, get some doubt after discussing with Gödel.
Then with comp, the existence of a physical universe dopes not make  
more sense than a creationist god. It simply does not work.

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).

I've read both and I don't think Max is/has pursued the rabbit hole of
implications of possible comp as far or as thorough as Bruno.

Then it's a matter of reasoning the few possible reasons why he doesn't

Sure, there are some Einstein's, but in many cases the guy with popularity
is always worse at the thing itself, precisely because he is better at
popularity.

This holds often not only in name polishing of science/reputation but also
in music we are not free from this: which opera composers that got Bach's
gigs, knowing full well of his work and existence, would fork over their
deals/connections just to disseminate another composer's (Bach's) work,
that we clearly see today as more complete and mature?

Zero, even though they were all superstars and doing quite well for
themselves. 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

depends on a continuum.  I would expect that most continuum based theories could support 
intelligent life simply because they permit lots of information.  But it's very speculative.

Liz,
As far as I know, Max does not have a theory. He just has a hypothesis with

One aspect of his hypothesis is that the creation of matter requires math
that is both consistent and complete.
Whereas Godel has seemingly to me proven that such math does not exist. Is
that true?

 mathematically (adverb), but cannot be claimed to ‘be’ the mathematics.
 Being predictive with/using mathematics does not prove nature is made of
 it. I deal with nature itself. Not maths. When you realise this you end up
 with dual aspect science. A 3 tiered epistemic framework practical for
 science


  This is of course the position that science has taken for the past few
 centuries without realising that there was any alternative. However, now
 that Max Tegmark (and of course Bruno) have argued that there is an
 alternative, simply *claiming* that nature cannot be made of maths no
 longer cuts the mustard. It's true that maths being predictive doesn't
 prove that nature is made of maths because as we know, science doesn't
 set out to prove anything, especially not sweeping ontological claims. But
 it still seems quite possible to me, at least, that Max may be onto
 something, because as he points out his theory explains the unreasonable
 effectiveness of maths in physics - so I will be interested to hear some
 counter arguments that explain this effectiveness on a non
 universe-is-maths basis. So far I've seen a bit of handwavium, but
 generally I've been underwhelmed by the alternatives presented to explain
 this, which leaves Max's theory out in front in terms of explanatory power,
 as far as this particular issue is concerned.

  Not that there aren't problems with Max's theory, of course. (It's mind
 boggling for a bear of little brain like me to attempt to grasp how it
 could possibly actually work) But it does seem plausible enough to
 deserve decent counter-arguments.


 One counter argument is to note that math has been unreasonably
 effective in Ptolemaic astronomy, Newtonian physics, fluid dynamics,
 non-relativistic quantum mechanics, and other theories which we now think
 were mere approximations.  This seems much more consistent with mathematics
 being descriptive rather than prescriptive.

 I'd say mathematics is just a matter of being very precise about axioms
 and what you infer from them so that you find lots of interesting
 consequences but don't fall into contradiction.
