And Bruno doesn't even know what questions to ask, like, "what does the pronoun "you" refer to, or what does "free will" even mean, or does the word "God" mean anything other than a amorphous grey blob, or does a chain of "why" questions ever come to an end?". Bruno hasn't even thought it important to ask these questions much less find the answers. > > > What you propose explains less and assumes more. > Y > ou assume: > Physical universe -> Turing Machines -> Conscious Minds > > + > > Turing Machines that exist in math -> Unconscious zombies > Whereas, we might simply assume: > > Turing Machines -> Conscious Minds > You conclude with " Conscious Minds " but I do NOT assume nor do I need to conclude that a conscious mind or the physical universe exist because I know both from direct experience. >> >> this simulation is being done >> >> by your physical brain.

Maybe other types exist, and maybe Harry Potter does too but there is no evidence for either. Well OK .... maybe I've overstated my case, the 2 slit experiment is some evidence that many worlds exist, and if an infinite number of them exist then Harry Potter might too .

But it isn't true. if strings exist (a big if) then every time you move your finger you effect the strings in your finger, and if the strings were different physics would be different and if physics were different chemistry would be different and if chemistry were different you would be different. > > > Why not review the current evidence? > If I ever run across evidence that computations can be made without the use of matter that obeys the laws of physics I make a solemn promise to review it. >> >> >> Perhaps mathematics comes from a desire humans have to develop a >> language that is especially good at describing the workings of physics. >> It's true as you pointed out that a lot of higher very abstract >> mathematics seems to have little or nothing to do with physics, but like >> any language once it is developed mathematics can be used to write fiction >> as well as nonfiction, perhaps a lot of it is like a mathematical Harry >> Potter novel. >> > > > > What do you believe is real, > John Clark is one example. > > > and why? > I think therefore I am.

Occam's razor applies. If physical objects exist, then the mathematical universes exists as a physical object. One must explain what the additional assumption of a mathematical universe adds or explains. > > It > [physics] > fails to answer, why if there is only one or some physical universes that > exist > > why those are exist while other, perfectly valid (from a mathematical > structure perspective) do not exist. If you think that mathematics is more fundamental than physics and if you think other physical laws have a perfectly valid mathematical structure then it is your responsibility and not mine to explain why they do not exist! The obvious explanation is that having a perfectly valid mathematical structure may be necessary for existence but it is not sufficient because physics is more fundamental than mathematics > > It answers why a universe having laws like ours has It does no such thing. > > It also has issues with the mind-body problem, The greatest mystery about the mind-body problem is figuring out what you would consider an adequate explanation. If I said X produced mind and X was mind you would protest and say that was just a tautology, and if it was not mind you would say "but X is not mind". I believe that mind-body problem fanboys forget that the chain of "why" questions either terminates with a brute fact or goes on forever. So after saying that consciousness is the way data feels like when it is being processed (by matter) there may not be anything more to be said. > > > and fails to offer any answer for why the universe exists at all. I suggest you read " A Universe from Nothing " by Lawrence M. Krauss , it doesn't explain why there is something rather than nothing but it does explain the enormous progress physics has made in just the last 20 years or so in explaining why there is a lot rather than very little. Pure mathematics has made zero progress on this matter in the same time. > > what is primary? Why do our thoughts exist? Why do they appear to > correspond to a well-ordered structure?

If mathematics is a language humans have devised to explain how the physical world works then the mathematical theory of quantum mechanics had to be the way it is or it wouldn't correctly describe the way the physical world works. And nobody would be crazy enough to come up with quantum mechanics from pure mathematics, instead experimental observation of the physical world determined what the mathematics in quantum theory should be. > > > and offers hope of deriving laws of physics from pure number theory. Hope is good, but as of September 13 2015 there is not even a hint of such a thing.
