In some school the motto is that God is a human product. It is crazy what you can make children believe! > > Once you identified 3 and 4 I need more knowledge to get to the > abbreviation of 34.

It is your right to scrutinize, even for billions years.

It is not really the time to re-evaluate them, it is on the contrary the time to remember them, and use them. There is no magic, it asks for works. But here just ask question when you don't understand a solution to an exercise, for example. Mathematical intuitions about some object comes from playing with those objects. It needs a minimum amount of exercise and practice, for not being fool by the superficial choice of the words. > > --------- > > BM: "...Be careful with the term "uncountable" which will have a > precise technical meaning. > > I call 'uncountable' what we cannot count (in toto) Good try. But what do you mean by "we" ? I asked you that question before. We the humans? We the mammals? We the animals? We the live being? We the universal numbers? We use the universal numbers with oracle, ... And then there is the problem to define "count", which is a very interesting unsolved problem. But there are progress: we can explain why universal machine have difficulties when they try to define concept like "0, 1, 2, 3 ...". > - the effects exercised on items within a set (as well as on > anything in the world) by "the rest of the world" to which we have > only a limited access - eo ipso we CANNOT count the unknown part. > Infinite IMO is uncountable, because you can always add 'another' to > it (common sense argument).

We, and by we I mean the readers of the posts of this thread, will be invited, I'm afraid there is no escape, of a bit Cantor theory of the Infinites, note the s. Cantor discovered the Diagonalization technic, which works in set theory, mathematical logic and computer science. > --------- > > BM: "We will axiomatized some mathematical notions, but only when we > are sure that we get the intuition right.

Not vice versa. Yes, yes, yes. Important to always keep this in mind. Theories/ machines/numbers are tools, they just push light on something, but they can introduce shapes and shadows themselves. Be careful now of not confusing a theory and the "betted things" the theory is supposed to talk about. In the case of numbers and machine they can be both the studying thing and the studied things, and this makes some hard to predict surprises if I can say. > * > I feel the paragraph as 'reverse thinking': our intuition is the > working of our human mindset, I would not apply it as proof for > getting the basics right, of which our mindset is a product. > > Similarly the 'universal machine' is a product of the human mind so > it cannot be invoked as evidencing the total which includes the > human mind. (Circularity). I think that the idea that ''universal machine' is a product of the human mind" is a product of your mind. And as such I respect that idea as an opinion. My opinion is that the universal numbers are indeed the product of universal numbers, and they have only partial controls on the relations. But there can be notable historical events like when amoeba invented the cable to develop into what we call brain, which are universal machine/number ... But this happened before, and after ... A more human-biased account could be that the universal machine has been discovered by Babbage, and then by Post, Turing, Suze, Markov, Kleene, Church, and some others. Accepting Church thesis, for a theoretical computer scientist it is a theorem, which can be proved for all enumerable class of computable function known up to now (hundreds of universal numbers are appearing each day, you are using one indirectly), or an axiom, in attempt to axiomatize. The universal machine has many names, you know: fortran, lisp, prolog, c, peano, zf, 3-body problem, quantum vacuum topology,... But please, I am explaining this right now, or read the literature or try to keep a later train, but it is on the type reasoning, and we have to get some amount of familiarity with computer science. You think the Mandelbrot Set is a product of the mind? http://www.youtube.com/watch?v=nyl5J33CJcE&feature=channel_page Remember that the definition of the Mandelbrot set M is not much longer than the definition of the circle. It is has been discovered by Fatou and Julia, and Mandelbrot. An important discovery, and I am about sure that, well not really M, but the rational part of C \minus M, is among the fortran, lisp, prolog, c, peano, zf, 3-body problem, quantum vacuum topology,... , company. > > BM: "...What is the "occamisation of a set"? > > The application of Occam's razor to cut off all that makes "it" > harder to understand and concentrate on the easy part.

I am agnostic there. Hmm... I can understand that "set" is an occamization of "concept", but set is supposed to be as occamized as possible, for practical purposes. So that we can easily figure out the meaning of the most elementary relations and operations on them. Sets are building block to talk about other things, like functions, computable functions, etc. > (I wonder if Russell will excommunicate me for that?) He could as well if he comes to suspect that you try to occamize what I am trying to say. The beauty of it, John, is that, with comp, the universal machine, despite its infinity of names, is such that it is able to demolish all attempts, by machines and even many gods, to be occamized. (By 'gods' I mean entities non emulable by universal machines). If the Supreme Secretary or any Ayatollah really knew what is a universal machine, they would send it immediately to a Gulag, both the machine and its universal user, I'm afraid. The universal machine or number or whatever finite thing is *the* major discovery. The real heroin of all I try to say. To understand the mathematical root of that discovery is what is needed to get the seventh step, and to understand why a computation is different from a description of computation. This helps for the last step. The eighth step, where you can add "QED", and, in the least, understand a different conception of "realities" than the current naturalist one. In the most, you understand why it is necessary, when assuming "we" are no more than turing universal, whatever "we" are.
