Dear Bruno: here we go again (quote from Ronald Reagan).
The "vocabulary" of different (belief?) systems. You seem to abide firmly at "axioms", meaning not more in MY vocabulary than postulates to make OUR (actual, conventional, ongoing) theories VALID. Changing theories make axioms invalid.

HUMAN? I doubt if we have a universally agreed-upon definition
(and please, count me into the 'universal) standing up to both 'living/nonliving' creatures, computers (as we knew them yesterday - including the skeletally composed AI) with all the potentials that can be filled in future, additionally, as it has been supplied in the past millennia. Mathematical logic is IMO a human achievement of yesterday. It is fine and supports our conventional sciences (more than usually presumed so) but not the 'total' of an infinite view. (What I do not have).
You may say: un-scientific, baseless, etc., I agree.
What I disagree about is a "firm" belief of "we know it all".

I can' agree more with this.


Not even 1+1=2.

But that is not all. We don't know it, perhaps. But we believe it very strongly and use it daily, and it does not mean anything to say that we doubt it. It looks like provocative for the pleasure.


Hence my joke of 1+1=11. Or Brent's 10.

Yes, a joke. I am glad you make this clear.


I claim: there are no numbers in Nature, it is us (allow me to call ourselves: 'humans') representing observations of 'natural' hints with their ongoing explanations into "number"-related (calculable?) formulations. Hence (our?) arithmetic.

Here I do not follow you. I am more confident in the elementary arithmetical proposition than on any sentences involving humans, which are much more abstract and complex entities.

Actually, I don't really believe in "human". By "we" I tend to mean all Löbian relative numbers, and this, on this planet, might start from the jumping spiders. I still respect a lot the "lesser animal" from bacteria to worms like my pet the planarians.

You say that there are no numbers in Nature. But is not Nature a human conventional projection? I don't believe necessarily in Nature. It looks like a fake God to me. But there is no problem with believing in an even basic (ontological) Nature, but then my point is that you might need to refuse the doctor proposition to get an artificial brain.

My point is logical. No theories can bring the numbers without assuming them (implicitly or explicitly), and assuming comp we *have to* entirely explain the "illusion of nature" from the numbers. Then computer science shows that such an enterprise makes sense.

I am no saying that the comp theory is true, but it presents at least a precise rational alternative to the Aristotelian naturalism, which tend to eliminate person (human or not).




As I already explained: the (human) genius formulated out of such theories an ingenious technology that is ALMOST good.
And I bow to that.

The difference between natural and artificial is artificial. Technologies, like living entities can give the best and the worst, and it is relative to what and who benefits from it.

THAN WHAT YOU WERE IMAGINING?" sounds like a claim to some priviledge to imagining - only YOUR WAY?
(I know you will vehemently deny that - ha ha).

To Guitarist:
"It's funny how this game keeps cropping up where people want to do stuff like: 1 + 1 = 11" You made my point - which was to (agnostically) expose that we have no approved authority to a ONE AND ONLY opinion.
Not even within what we may call 'possible'.

Hello Everythinglisters,

First post here, and seems fun to get lost reading the discussions from time to time, so here somebody contributing with a more musical tendency.

It's funny how this game keeps cropping up where people want to do stuff like: 1 + 1 = 11

If people are sincere about pulling whatever sums they feel like with personal justification, then we might as well say 1 + 1 = 0, with a kind of zen logic, where everything = nothing as a fancy justification.

Well in Z_2 = {0, 1}, we do have a law with 1+1 = 0. (modular arithmetic). But 1 is still different from 0. But I get your point.


And anybody still willing to assert this could post their bank account details and pin numbers and be freed from arithmetic dictatorship by having their account cleaned out by other everything listers that DO believe in sums, successors etc. as 0 = whatever they want, and the sum of their balance doesn't really matter, as it's only some personal belief shared by a few control freaks.

Right. I think that people believing that 1+1 can be different of 2 are just imagining something else. It is not an arguent that a truth is not absolute, but that the notation used to described it can have other interpreations. In the Z_2 structure, which plays a key role in many places: 2 = 0. But 2 does not represent the successor of of the successor of zero, it represents the rest when we divide by the usual number 2. It really means:

odd + odd = even   (the rest of 1 + 1 divided by 2 = 0)
even + even = even (the rest of 2 + 2 divided by 2 = 0)
odd + even = odd  (the rest of 1 + 2 divided by  2 = 1)



Guitar and composition imho, have arithmetic overlap, albeit in a less than total sense, which is why I won't have to post my details here :)

Guitar is hardest, imo. You need good trained digits!




Looking forward to contributing from time to time.


You are welcome,

Bruno

By no means. It is a word-flower, a semantic hint, something in MY agnosticism and I feel like a semantic messenger only. I accept better expressions.
(Except for "absolute truth" - ha ha).
And Teilhard was a great master of words.

Brent, thanks for the appreciation!

My point was simply that anybody's 'truth' is conditioned.
We have no (approvable?) authority for an ABSOLUTE truth. Whatever "WE" accept is "human".


Is that an absolute truth?

In my humble opinion, "WE = human" seems to me quite relative. When I listen to the jumping spiders or the Löbian machines, most seems to disagree.

We are not human beings having a spiritual experience. We are spiritual beings having a human experience.

What is Mother Nature accepting?

I am the 3rd kind of the two: think not in binary, just in plain peasant logic, when 1 and 1 make 11, nothing more.
So Bruno's "absolute truth" may have even more relatives.
John

Or less facetiously, (The father of Kirsten)+(The father of Gennifer)=(One, me) and (one raindrop)+(one raindrop)=(one raindrop). So whether successor(x)=(x+1) depends on the applicability of arithmetic to your model.
