This it would require aleph_1 resourses to compute such a problem what had only aleph_0 different possibilities. Even God itself cannot contradict mathematical facts. Thus there is no Pre-established (or ordained) Harmony, as such is a self-contradictory idea. So each monad reflects the whole system, but with its own perspective emphasised.

Re: Re: A Dialog comparing Comp with Leibniz's metaphysics
Roger, Every natural number is distinct from all others. So your characterization of them as simple with no internal parts has to be incorrect. Leibniz himself says that every monad is distinct: "In a confused way they all strive after [vont a] the infinite, the whole; but they are limited and differentiated through the degrees of their distinct perceptions." http://www.rbjones.com/rbjpub/philos/classics/leibniz/monad.htm Also nowhere in the Monadology do the words extend, inextended, unextended or nonextended appear. So could you give us a link to where he says they are inextended.

ROGER (a Leibnizian): Hi Bruno Marchal Perhaps I am misguided, but I thought that comp was moreorless a mechanical model of brain and man activity. BRUNO (a comp advocate):... I am not a comp advocate. I use comp because it gives the opportunity to apply the scientific method to biology, philosophy and theology. I search the key under the lamp, as I know I will not find it in the dark, even if the key is in the dark. I am just a technician in applied logic. I inform people that IF comp is correct, then physics arise from elementary arithmetic, which includes a theology of number. The fundamental science, with comp, is the thology of numbers (that is: the study about the truth on numbers: this includes many form of truth: provable, feelable, observable, knowable, etc. With the usual classical definition. It masp closely with the theology of the neoplantonists and of the mystics, and certainly some aspect of Leibniz. ... Not really. Comp is the hypothesis that there is a level of description of my brain or body such that I can be emulated by a computer simulating my brain (or body) at that level of description. ROGER: Very good. "At that level of description" is exactly the point of view I have adopted regarding Leibniz's metaphysics, discussed below. OK. This is wholly my own version, since a possible problem arises in understanding what a Leibnizian substance is. The reason is that Leibniz describes a substance as potentially any "whole" entity, that being either extended body or inextended mind. But because extended bodies (despite L's familiarty with atomism)* can always be divided into smaller inextended bodies, extended bodies cannot be substances in L's metaphysics. Hence L substances are the inextended representations of extended bodies. OK. (Of course here 'substances' are not the Aristotelian primary matter). *[In my view, the issue that fundamental particles cannot be subdivided, can be replaced by the the Heisenberg Uncertainty principle, which in effect allows one to consider corporeal bodies as inifinitely divisible in the sense that one cannot arrive at final separate pieces without uncertainty. So one cannot come to a final state, holding up L's argument that corporeal bodies cannot be sustances. There's nothing left that one can point to. ] I can agree, but Heisenberg uncertainties are an open problem in the comp theory, as the existence of particles, space, physical time, etc. Natural numbers qualify as Leibnizian substances, since they are inextended and not divisible. Well, 24 is divisible by 1, 2, 3, 4, 6, 8, 12 and 24. OK, you can take it as a joke. But I fear you put too much importance in the particular notion of numbers, ad we can use LISP programs instead of numbers. This plays some role in the derivation of physics from the comp first person indeterminacy. I do see your point that numbers "are not divisible", though. But Fortran program, machines, neither, in such a similar sense. They also do not have parts, so in L's terms, they are simple substances, which is another name for monads. Natural numbers are thus (Platonic) monads, although not all monads are natural numbers. A man-- me, for example-- is not a natural number even in the Platonic realm, but yet is a monad, separates comp from L's metaphysics. I'm afarid that your notion of monad becomes to general, as with comp, a term like a man is ambiguous. Either we refer to his body, and that is a (relative) number, or to its soul, in which case, comp prevents us to take it as a number. It is nothing third person describable. Todays machines already know that, if you listen carefully (which asks for work à-la Gödel-Löb, but terrribly simplified by the use of Solovay theorem on G and G*. In addition, not all substances a
