It’s uncivilised for sentient beings to undergo involuntary pain and suffering – or any experience below hedonic zero. — David Pearce
In everyday understanding, when we count, we associate one thing with 1, then the next thing with 2, etc. Literally. We say the numbers, one for each object as we count the objects. Mathematically. this is expressed as a function from the set of things counted to a set of numbers: — TonesInDeepFreeze
It is the very point that you can count more than one way.
You can count 'War And Peace as the first, then 'Portnoy's Complaint' as the second. Or you can count 'Portnoy's Complaint' as the first, then 'War And Peace' as the second. In either case, both counts show that there's a first and second, thus there are two. — TonesInDeepFreeze
The sequence a,b,c,d,e is a sequence of five letters. e is letter five. — jgill
If I'm not mistaken, in another thread, you were using the word 'refer' in the sense of 'denote'. So if not 'denote' what exactly do you mean by 'refer' in this thread? — TonesInDeepFreeze
The numeral '5' has meaning. The number 5 is not the numeral '5'. — TonesInDeepFreeze
The fact that 5 is a count doesn't contradict that 5 also is a number no matter what it happens to count. — TonesInDeepFreeze
5 is the successor of 4. 4 is the successor of 3. 3 is the successor of 2. 2 is the successor of 1. 1 is the successor of 0.
No matter what the numbers count, they exist by virtue of successorship or by being 0. — TonesInDeepFreeze
of course are different, but nothing is "invalidated". Saying the pairings are "invalidated" is not even sensical. — TonesInDeepFreeze
You're doing it again! We do not use '2' to name a book. '2' does not denote a book. — TonesInDeepFreeze
We can switch them so that we have:
{<'Portnoy's Complaint' 1> <'War And Peace' 2>}
But the greatest number in the range is still 2. — TonesInDeepFreeze
That doesn't contradict that when we see discrete objects then we may count them. — TonesInDeepFreeze
How we use the concept of counting is a matter of practical approach, such as putting the water in a beaker with lines and counting the lines in the beaker to the point the water level ends or whatever. Whatever difficulties there may be conceptually with that, they don't negate the more basic notion of counting by bijection. — TonesInDeepFreeze
You present as so confused that I wonder whether you are posting as some kind of stunt or dumb cluck character. — TonesInDeepFreeze
(2) A count is the result of counting. "The count of the books is five."
A number (we're talking about natural numbers in this context) is a count in sense (2). That doesn't preclude that a number is a mathematical object. — TonesInDeepFreeze
We better dispense with that notion. It's nuts. A number is not a book. — TonesInDeepFreeze
So the numeral does not denote a book, but rather it denotes the number that is paired to the book in the bijection (or, in everyday terms, in the pairing off procedure we call 'counting'). — TonesInDeepFreeze
We don't say "''1' denotes 'War And Peace' and '2' denotes 'War And Peace' together with 'Portnoy's Complaint'". That's crazy. — TonesInDeepFreeze
But to return to the earlier example of playing chess, one can fanatically aspire to improve one's game and play to win even though one will invariably lose. — David Pearce
Two invincibly happy (trans)humans can play competitive chess against each other and both improve their game. Honestly, I don't see the problem! — David Pearce
Rather, what needs questioning is the widespread assumption that the "raw feels" of suffering are computationally indispensable. If the indispensability hypothesis were ever demonstrated, then this result would be a revolutionary discovery in computer science: — David Pearce
Maybe contemplating the pain of a defeated opponent sharpens the relish of some winners today. Let's hope such ill-will has no long-term future. — David Pearce
But as I said, emphasizing hedonic uplift and set-point recalibration over traditional environmental reforms can circumvent most – but not all – of the dilemmas posed by human value-systems and preferences that are logically irreconcilable. — David Pearce
1 is the count at the first member of the set, a particular unity (whatever it is). 2 is the count at the second member of the set. Etc. And '1' and '2' name different individual numbers. And 1 is the count of the members of the set with one unit. And 2 is the count of the members of a unity that is a set with two members. And a set with one member is a different kind of unity from a set with two members. — TonesInDeepFreeze
'2' denotes the number 2. The number 2 is the count of a set with two members. And a set of two members is itself a unity as a set. But '2' does not denote a unity; it does not denote the set that it counts. It denotes the COUNT of a set that is itself a unity. When we say that a set is a unity, we mean that it is one set, while we recognize that the number of members of the set may be greater than one. — TonesInDeepFreeze
"It's not enough to succeed. Others must fail", said Gore Vidal. “Every time a friend succeeds, I die a little.” Yes, evolution has engineered humans with a predisposition to be competitive, jealous, envious, resentful and other unlovely traits. Their conditional activation has been fitness-enhancing. In the long run, futurists can envisage genetically-rewritten superintelligences without such vices. After all, self-aggrandisement and tribalism reflect primitive cognitive biases, not least the egocentric illusion. Yet what can be done in the meantime? — David Pearce
If society puts as much effort and financial resources into revolutionising hedonic adaptation as it's doing to defeat COVID, then the hedonic treadmill can become a hedonistic treadmill. Globally boosting hedonic range and hedonic set-points by biological-genetic interventions would certainly be a radical departure from the status quo; but a biohappiness revolution is not nearly as genetically ambitious as a complete transformation of human nature. And complications aside, hedonic uplift doesn't involve creating "losers", the bane of traditional utopianism. — David Pearce
But neither P nor Q are stated coherently by you. And there's no reason to think anyone wants P or Q anyway. — TonesInDeepFreeze
Of course the notion of 'one' is related to that of a unity. But even aside from parsing, I don't know who in particular you think holds that "The "2" represents two of those individuals together, and "3" represents three, etc". It would help if you would cite at least one particular written passage by someone that you think is properly rendered as "the numeral "1" represents a basic unity. an individual. The "2" represents two of those individuals together, and "3" represents three, etc" and "'2" and "3" represent some kind of unity". — TonesInDeepFreeze
t would help if you would cite at least one particular written passage by someone that you think is properly rendered as "the numeral "1" represents a basic unity. an individual. — TonesInDeepFreeze
1 (one, also called unit, and unity) is a number and a numerical digit used to represent that number in numerals. It represents a single entity, the unit of counting or measurement. For example, a line segment of unit length is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer.[1] It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. — Wikipedia
In the very most basic example, we can ask whether the number -2 is prime. The question may seem nonsensical, but it can motivate us to put into words the unique role of 1 in the whole numbers. The most unusual aspect of 1 in the whole numbers is that it has a multiplicative inverse that is also an integer. (A multiplicative inverse of the number x is a number that when multiplied by x gives 1. The number 2 has a multiplicative inverse in the set of the rational or real numbers, 1/2: 1/2×2=1, but 1/2 is not an integer.) The number 1 happens to be its own multiplicative inverse. No other positive integer has a multiplicative inverse within the set of integers.* The property of having a multiplicative inverse is called being a unit. The number -1 is also a unit within the set of integers: again, it is its own multiplicative inverse. We don’t consider units to be either prime or composite because you can multiply them by certain other units without changing much. We can then think of the number -2 as not so different from 2; from the point of view of multiplication, -2 is just 2 times a unit. If 2 is prime, -2 should be as well.

What does it mean? — fishfry
When I say that 2 + 2 = 4 has meaning, it's because I have defined '2', '4', '=', and '+' according to the standard mathematical conventions, either within the Peano axioms or ZF set theory. In other words from my viewpoint 2 + 2 and 4 and '=' all refer to something. The somethings that they refer to are abstract mathematical objects. And I will stipulate that when you challenged me to define exactly what I mean by those, I was stuck. I admit that! But at least by saying what these expressions refer to (in my mathematical ontology), I can thereby assign meaning and value to them. The meaning and value of these expressions derive from the referents I have assigned to them. — fishfry
But you say that 2 + 2 and 4 don't refer to anything. So it is now incumbent on you -- not just for me, but for working out your own thoughts for yourself -- to figure out how to define the meaning and value of syntax tokens that you claim don't refer to anything at all! Do you take my point here? — fishfry
There is nothing simple about your point of view. Nor have you explained "what '=' signifies" in the least. I haven't seen you do it. — fishfry
Do you accept that there is a difference between "is the same as" and "has the same value as"? The former phrase is the phrase used by the law of identity. The latter phrase is what is signified by "=", as the Wikipedia entry indicates. — Metaphysician Undercover
It's funny. You can't answer the question I put to you: If 2 + 2 has no referent, how does it obtain its meaning or value? — fishfry
But I have a perfect understanding of what the meaning and value of 2 + 2 are. — fishfry
I DO have a crystal clear understanding of how the meaning and value of 2 + 2 derive from the mathematical REFERENT of the expression. Whereas you DENY there is a referent, so you are STUCK trying to figure out how to derive the expression's meaning and value. Why don't you work on this and let me know if you have any fresh ideas on the matter. — fishfry
Agreed on this point. But note that I can define what the value of 2 + 2 is, and you can't. Because you deny that 2 + 2 has any referent. — fishfry
But you deny the expressions have any referents at all, so I don't see how you're in a position to claim that they have the same value, or different values, or any values at all. How can we know their values if they have no referents? — fishfry
I, on the other hand, have a perfectly sensible way to define their values, based on the referents I have assigned them in PA or ZF. I can do this from first principles. — fishfry
* You claim 2 + 2 has no referent, and since it has no referent, you can't tell me how to determine its value. — fishfry
What I can't get past is that physicist have used General Relativity to derive a size for the universe, and pretty much agree on the result; in doing so they relied on the relativistic versions of the equations you refer to.
And yet, without showing us the calculations, you insist that they are wrong.
I don't think there is more to say here. That the velocity of light is a constant, fixed for all observers, is fundamental to physics. — Banno
I understood that; I thought you meant that you do want to take '2' and '3' as representing a type of unity, while you think that that is contradicted by 'the numeral "1" represents a basic unity. an individual. The "2" represents two of those individuals together, and "3" represents three, etc" so that it needs correction .
Am I not correct that that is your view? — TonesInDeepFreeze
More basically, I don't know why one would fret over any of this, since I don't know anyone who claims "the numeral "1" represents a basic unity. an individual. — TonesInDeepFreeze
In sum, I can't make sense of what you're trying to say. — TonesInDeepFreeze
Suggestion: You could reference some actual piece of mathematical or philosophical writing that you disagree with and show how you think you can correct it. — TonesInDeepFreeze
Yes, as I thought, you find that there is a problem with the notion (whatever it means) that 'the numeral "1" represents a basic unity. an individual. The "2" represents two of those individuals together, and "3" represents three, etc". — TonesInDeepFreeze
But (aside from even trying to parse the broken phrases) I don't know who says anything along the lines of 'the numeral "1" represents a basic unity. an individual. The "2" represents two of those individuals together, and "3" represents three, etc". So I don't see why you think it is a problem that needs to be addressed. — TonesInDeepFreeze
I thought you meant that there is a fundamental problem with:
"The numeral "1" represents a basic unity. an individual. The "2" represents two of those individuals together, and "3" represents three, etc. But then we want "2" and "3", each to represent a distinct unity as well."
And that your supposed solution to the supposed problem is:
"[...] we have to allow that "1" represents a different type of unity than "2" does [...]" — TonesInDeepFreeze

I think this is a small example of a larger problem - the inability to accept reality.
Reality deniers come in many shapes & sizes: Vaccines, the Holocaust, Flat Earth, climate change, etc.
I wish I knew what causes this. I have close relatives & friends who deny at least one (and typically many) aspects of reality. My amateur psychologist analysis is that this is partly driven by fear. The way they view themselves and how they fit into the world is being challenged. And they are afraid of that change.
And the thing is - they are not stupid people. You can have intelligent conversations with them on any number of issues, you can share laughter & tears, etc. — EricH
Where can I actualy read anyone explaining the concept of numbers that way? — TonesInDeepFreeze
No I don't. Nor should you. But we each choose our paths. You might consider joining forces with Metaphysician Undercover. His concern is the supposed equality between 2+2 and 4. :roll: — jgill
I'm sure there a bunch of terms that physicists pull from somebody else's discipline because they keep getting punked by "reality." It's no wonder others feel free to chime in when they see the struggle using familiar terms. — James Riley
Waves might be substrate-less. That is, they may not be like the waves in the water, which is the substrate for the waves. They are only waves. — spirit-salamander
stick can be used to bash over the head, or it can be used as a lever to roll a giant rock down a hill. Or it can be used to scratch symbols in the sand. The same basic physical form can have radically different functionalities. Therefore radically different abilities. So even if beings have the same physical form, they can have radically different 'shapes' with respect to their environments. And hence different properties as reflections of their 'shapes.' Which are different abilities.
If as a result of a purely mental operation otherwise identical physical things can acquire different properties, then these properties are instantiations of the mental. And if these properties enhance survival then they result in progressive physical modifications. So the 'shape' of the mind in the world is a product of its own mental operations (in a physical context) and not merely a physical product. — Pantagruel
pecifically, I like the notion of mental shape because shapes have specific properties, and our properties or abilities 'fit' with what I've described as environmental gradients. — Pantagruel
First, it is unlikely that there are exactly two types of stuff, particles and waves, absolutely differentiated. The reality must undoubtedly be so much more complex that duality ceases to have descriptive relevance. Second, all matter thus far experienced has evolved from common antecedents, so it is most likely that if particles ride a more foundational wave substance, the particles evolved out of it. Its not conceptually impossible for eternally distinct particle and "wave" substance to exist, nor is anything else, but the most probable explanation due to their pervasive interactiveness is that they have a common origin with impulsion towards combinatory states. As a fanciful example, if particles ride dark matter waves their behavior is probably mutualized enough with dark matter for whatever reason that this amounts to a synthetic substance in some degree. — Enrique
Hmmm. Excuse my error, then. — Banno
Now let's position the "system of believe" relative to the true doubt. The doubting person cannot be "within" the system of believe because that would mean that the system is already accepted by that person. The doubt must be aimed at the system as a whole, because as "a system" we must assume that there is consistency between the parts (individual beliefs) of the system, and one cannot reasonably doubt one part of a consistent system. So true doubt must be directed at the system as a whole.
Would you agree with that? If we say doubt can only occur from within a system of belief, that system of belief must be other than the system being doubted. The two systems may not even be remotely related. So the assumption "doubt can occur only within a system of believe", is really an irrelevant point, because that system of belief must be other than the one which contains the belief being doubted.. And if we take the game analogy, true doubt can only come from the person who refuses to play the game, because to play the game is to consent to the rules, and to consent to the rules is to forfeit your right to doubt them. — Metaphysician Undercover
Here's how what I stated above is relevant to this thread. If we assume that any specific language-game is a representation of a system of beliefs (consistency being a necessary requirement of "system"), then true doubt can only be directed at any specific language game from outside that particular game. I.e. the person who refuses to play. I'll call that person the skeptic, is the only one who may cast true doubt. If we assert that the skeptic must pose one's doubt from a position of being within a language-game, within a system of beliefs, then that system providing the skeptic's approach, must be other than the one doubted, and there cannot be consistency between these distinct language-games, or else true doubt would be impossible. This implies that language in general, as a whole, cannot be represented as a single language-game, because of the inconsistency between distinct language-games which makes true doubt a real thing.
The other course we could take, is to allow inconsistency within any specific language-game, and system of belief, thereby allowing for doubt within the system. If there is inconsistency within the game, or system, then doubt from within would be true justified doubt. But that ought to be seen as epistemologically unsound, to allow inconsistency to inhere within a system. It produces a faulty definition of "game" or "system", one in which the rules of the "game" contradict each other, or the "system" has parts which oppose each other, or are not conducive to its function.
So the logical course is to maintain that a language-game, or a system of beliefs, is necessarily consistent, and true doubt must be directed at the system as a whole, from outside that system. This is also the most practical solution, because if inconsistency appears to inhere within a system of beliefs, it is extremely difficult to isolate the defective parts, with the goal of doubting just those parts. So the entire system must be doubted as a whole. This implies that refusal to play the game is required, and we're at the point of doubting the entire system anyway. — Metaphysician Undercover
I explained very clearly why doubting the entire belief system is the only reasonable form of skepticism. Beliefs within a system are necessarily logically consistent and interrelated. That's what makes it a "system". To doubt one belief within a system requires doubting the beliefs it is dependent upon, and it is implied that the beliefs dependent upon the doubted belief are doubted as well. So it's unreasonable to doubt one belief without doubting the entire system within which it is integrated,
This is why the idea that there are hinge propositions which are somehow indubitable is unacceptable epistemology. If the entire system is intrinsically consistent, and valid, which it must be to be a "system", then no part of the system can be doubted without doubting the whole. And this would require doubting the supposed hinge propositions as well.
The preceding result, is the logical conclusion of assuming that beliefs exist as part of a "system". If we remove that premise, and allow that beliefs have individuality, free from the influence of an overall system, then it is reasonable to doubt individual beliefs. But then the whole game analogy, and the idea of hinge propositions is completely inapplicable. . — Metaphysician Undercover
A belief system must be coherent to fulfill the conditions of being a "system". This means that if one belief within the system is dubious, then the entire system is dubious due to all the beliefs being related through coherency. So it makes no sense to say that some beliefs within the system are dubious but the foundational ones, hinge propositions cannot be doubted. This is like taking a deductive argument, and saying that the logic is valid, the conclusion is dubious, but the premises are beyond doubt. If the logic is valid, we cannot doubt the conclusion without doubting the premises. — Metaphysician Undercover
But then it is incorrect to call this a "system", that's the whole point. If we move away from the "system" representation, to the "big, baggy monster of ways that people do things" representation, then the idea of hinge propositions makes no sense at all, because there is no system for them to be supporting. If there are systems, then the systems themselves must be coherent, so to doubt any aspect of the system implies a doubt of the entire system, including any supposed hinge propositions. Either way, the notion of hinge propositions which are beyond doubt is fundamentally incorrect. That's why Kuhnian paradigm shifts are a reality, the entire system along with its foundations must be dismissed. — Metaphysician Undercover
What necessity forces you to use language? People can choose not to use language as freely as they can choose not to play chess. — Luke

How is this different to the game of chess? It is not as though people are forced to play chess against their will by the deterministic laws of nature, or that they are physically unable to make illegal moves. Chess is also "shaped...by freely chosen activities of free willing beings", yet it is still a game for all that, and has rules too. — Luke
