Lee Smolin in his book "Time Reborn" says the obsession so many physicists have had on getting rid of time is the reason little progress has been made at finding a quantum theory of gravity. Brains are certainly not fundamental but are nevertheless of vital importance to cognition, so if we're just talking about consciousness it doesn't make any difference if time is ultimately fundamental or not because nothing is more apparent and important to a consciousness than time. And don't tell me time is just a illusion because that explains nothing, a illusion is a perfectly respectable subjective phenomenon and subjectivity is what we're talking about. > *Time is an internal indexical,* > The index never changes, but time does and so does consciousness. >>Definitions are a bore .

So if I were to define a dragon as a huge fire breathing lizard that can fly it would be ridiculous of you to dispute my claim that by defining them I have proven dragons exist. > *> Without agreeing on what is a computation,* We don't learn by reading definitions, we learn from EXAMPLES. A definition is made of words and all of those words have there own definitions also made of words and all of those words have there own definitions also made of words and [...] You seem to be very big on fundamental stuff but if we're talking about meaning definitions are most certainly NOT fundamental, but examples are. Where do you suppose lexicographers got the information to write the definitions in their dictionary? So forget definitions, just compute 2+2 without using physics and I will concede defeat and nominate you for a Nobel Prize. >>The trouble with arithmetic is it doesn't change. > > > *>Nor do a block universe;* > And that is exactly why consciousness can not directly perceive the block universe and in fact until a century ago nobody was conscious of the idea, and even today nobody knows if it's a correct view of reality. At best it's just an approximation, and it can't even approximate what's going on at the center of a Black Hole or at the instant of the Big Bang. >*Just ask the copies, they know well what they are living.* > And I predicted that would happen long before the experiment started. > *Wat I request is that you tell me what the H-guy can expect to live* > And what I request of you is far far easier than a prediction, all I want you to do is go somewhere look around and tell me what you see. Just answer the following question: "After the experiment is completed and the 1 H-guy became 2 H-guys what 1 and only 1 city did the H-guy end up in?". If you can't answer that then it was not a experiment and it was not even a question, it was just a series of words with a question mark at the end. > > *You have already said that the H-guy survives* [...] > I can make all sorts of statements about the H-guy because I know exactly what I mean by "the H-guy", but you have no idea what you mean by "the H-guy". > >> I predicted the guy who saw Moscow would become the Moscow guy and the >> guy who saw Washington would become the Washington guy, > > > >*Sure, but that is tautological. * > Exactly! Seeing Moscow is the one and only reason the Helsinki man became the Moscow man. So why did I see Moscow? Because I'm the Moscow man. Why am I the Moscow man? Because I saw Moscow. That may not be deep but like all tautologies it's true, and I remind you it's your thought "experiment" not mine. > >The prediction is on which guy you can expect to be, > Which guy who can expect to be? Bruno is unable to say what the ASCII sequence y-o-u means in the above sentence and that's why Bruno is so fond of personal pronouns, when people duplicating machines are involved they help cover up the gaping holes in logic. > *from the 1p, after pushing the button, with will admit that the > symmetry is broken, and this in a way they were unable to predict with > certainty in Helsinki.* > Unable to predict exactly what in Helsinki? >>Regardless of if X stands for a banana or one of the 7.5 billion "the >> first persons" on the Earth at the current time, if X becomes 2 X it's >> brain dead dumb to ask what one and only one thing will happen to X. > > > > *That is refuted by both copies,* > Wonderfull!

I'm pretty sure it doesn't refer to anybody who remembers being the Helsinki Man but other than that I have no idea what one and only one thing you mean by "he", if this were everyday life I'd know but this is very far from everyday life because "he" duplicating machines are involved. >>Which one of the two "1-views themselves" do you want to know about?
