But you wouldn't ban Sculptor. No, I wouldn't. Banning Sculptor because he's rude is a leftist thing to do but banning Motor Daddy because he disagrees with you is obviously not.
Magnus Anderson wrote:gib wrote:Motor Daddy wrote:First you say that's not a fact, then you say fine, you'll give me that. Which is it? Is 2 + 2 = 4 a fact, or not?
I'm saying we can go either way. It's up to you. It all depends on what you mean. I'm showing you the logical options you have and where they lead.
You can't go either way. 2 + 2 = 4 is either a fact or it is not. Yes, so the logic can go either way depending on how you define fact. You are merely saying that if we change what that expression stands for that we can make it false e.g. if what we mean by "2" is "three", it becomes false. But what you're doing here is changing the meaning of the expression. You can do the same with any other kind of statement. You can do it with "The Earth is flat" too. But you don't say that. You don't say we can go either way with "The Earth is flat". You don't say that if we define the word "flat" to mean "round" that we can make that statement true. Basically, what you're failing to realize is that the truth value of a statement is determined AFTER its meaning is established. You first UNDERSTAND what someone is saying and THEN determine whether or not what they are saying is true or false.

Philosophy forums will have a whole different set of rules. It is the place for unscientific claims (opinions, conjecture, reason, etc.), so I wouldn't ban Sculptor for making unscientific claims on a philosophy forum. But it all comes down to the rules. Are they being violated or not? And as I said before, if Sculptor is violating ILP forum rules (which he probably has given all the lude vulgarities, name calling, and character attacks he engages in), I'll back you up 100%. But remember what I also said: we've probably all violated ILP forum rules at one point or another (especially name calling and character attacks), so be prepared to suffer the consequences of your own statutes. You especially, Magnus. I could probably find 100 posts in which you carelessly attacked other members with vulgarities like "idiot" or "imbecile" or "moron". So if you want to ban Sculptor on the grounds of name calling and character attacks, be prepared to be brought up on the same charges.

A scientific "fact" is a fact according only to the first definition.

You said that banning Sculptor for his rudeness is a lefty thing to do and that you're against it. You did say that, right? You stated it quite explicitly.
But now, you're saying that it's totally fine for a science forum to ban its members merely because their beliefs do not align with those of the scientific establishment.
It's perfectly okay for a science forum to ban someone who wants to make the case that the Earth is flat (regardless of how well presented their argument is) but it's totally not okay for a philosophy forum to ban rude people (that's a horrible lefty thing to do.)

First of all, why should forum members be punished for something they said 10 years ago? Who cares? And if it's true that they should be punished, then they should be punished -- whether they like it or not. Your argument is no more than an appeal to consequences.
But your earlier argument -- the first that you presented in this thread -- was that you're against banning Sculptor because it's a lefty thing to do and because it violates our right to free speech. Your argument wasn't "I don't want Sculptor to be banned because if we ban him we'll also have to punish every single person who violated the rules in the past but wasn't punished for it". That's a different argument and I'd like it if we could stick to one at a time.

2+2=4 is definitively true since the very meaning of the mathematical operators in this context and the necessary relations between 2 and 4 make this an anaytically true fact.
"The earth is Round" is an emprical fact and is not analytically true but synthetically true.
Actually the world is not "round" it is in fact an oblate spheroid, that is a fact but will never be an analytical fact.

Magnus Anderson wrote:The word "fact" simply means "that which is true". Given that "2+2=4 is true" and "Whatever is true is a fact" it follows that "2+2=4 is a fact".
Magnus Anderson wrote:We did verify it. And we verified it in reality. But we didn't need to. Have we verified that 1 billion + 1 billion = 2 billion? Where else can we verify things but in reality? In our heads. I never said we couldn't do this, just that this wouldn't count as scientific (or a fact). You just have to understand what that statement stands for so that you can know how to go about verifying it. "2 + 2 = 4" simply means that expressions "2+2" and "4" mean one and the same thing. You bet. So in order to verify that statement, you have to check what these expressions mean. You have to understand their meaning beforehand, if that's what you mean. If they truly represent one and the same thing, then the statement is true. Otherwise, it's false. Agreed. But where in reality is the meaning of those expressions located? It's located within human minds. Ah, so you're considering introspection as counting as verification (empirical?) So to discover the meaning of those expression, you have to look inside human minds. But whose minds? Well, that depends on whose word-concept associations we're talking about. If we're talking about mine, we have to look inside my mind.

Pedro I Rengel wrote:Well, I mean, it's either yes or no. It either depends on verifiability in reality, or it doesn't.
Pedro I Rengel wrote:We tested it by adding 2 beans to 2 beans. No we didn't. I can also say the sun is round without testing it But we do need to test that 2 + 2 = 4?, and know it's true (enough). Because you rely on other people's verification. I can say any planet anywhere is round (enough) and know I am right. I do not need to go around testing every planet. You would if you were the first scientist to propose this. It still refers to reality, and its relationship to reality is what determines the validity of its logic No it isn't, not the fact of consistent internal rules.
Pedro I Rengel wrote:One, in fact, does. That is the whole point. Until you have tested a logical system against reality, you don't really know if it makes sense. How the hell do you come to that conclusion? Other systems, equally consistent, like the Boolean, have been developed and discarded because they don't stand to applicability to reality. Boolean logic has not been discarded. I don't know where you're getting your information from. Many mathematical propositions have been discarded simply because they don't correspond to reality, without violating any actual known mathematical rules. Math is actually largely composed of this.
Pedro I Rengel wrote:Except, in reality, it went the other way around. For thousands of years math was simply expressed rhetorically. Then propositions, operations, and rules were developed as abbreviations. What you are saying is like saying that ancient theater was just movie making, they just hadn't developed photography yet.

Now you seem to be turning on that and saying the symbols and logical operators are more than just abbreviations, they're central to the very nature of logic itself, without which you wouldn't have logic (or something like that).

No it is not. It refers to something in reality. If the nature of that something turns out to be different from what we thought (what the definition says) then our definition refers to something that doesn't exist.
And then anyone who clings to the word "time" is living in a fantasy world?
This is what we did with the word "sun". Ancient religions (I believe the Egyptians) use to believe the sun was a god being pulled across the sky in a chariot. But when we discovered the sun was really a huge ball of burning hydrogen, we didn't start calling it the "shtun", we just said the sun isn't what we thought it was. <-- Are you saying this was an invalid move? Are people correct in saying the sun is a god being pulled across the sky in a chariot simply because that's what the concept was at one point (like people being correct in saying dragons breathe fire)?
If that's what you're saying then I don't know what the point is of arguing on a science forum that time is absolute--no more than I would know what the point is of arguing on a science forum that the sun is a god being pulled across the sky in a chariot. If what Motor Daddy meant by "fact" is simply what's true of his definition of time (which he didn't make explicit), then why is he surprised that he got banned seeing as how nobody on any science forum shares that definition or even knows that's the definition he's using? I challenged him on this because it seemed obvious that when he claims he got banned for presenting FACTS, his intention was to make it sound like he was present the truth about reality and that the scientists are living in a fantasy world and were being completely unscientific. Ironically, it turns out that he's living in a fantasy world and is the one being unscientific (or in his word, RELIGIOUS).
But yes, you do have to look outside your own mind to understand what people mean by '2', '4', '+', and '=', but as far as scientific observation/verification goes, you're only verifying what people say about the meaning of '2', '4', etc. (i.e. you observed the physical act of speaking). As for observing/verifying what's going on in their minds, you're inferring--that is, you're taking their word on faith (which is perfectly reasonable)--or better yet, the act of listening to their words simply instills the meanings of '2', '4', etc. in your mind.
But what I mean by "verifying/observing that 2 + 2 = 4" (and I suspect you know this) is that before you can believe that 2 + 2 = 4, you must take two object and put them beside another two objects and count them. If you get 4 objects, then that confirms that 2 + 2 = 4. <-- I'm saying one doesn't have to do that in order to know that 2 + 2 = 4.
