No, it was three separate situations. Sorry if that wasn’t clear. It is applicable to t1, but given the supertask described in P3 there’s no coherent ...
P1. When the letter X is given a definition it retains this definition until it is redefined. A1. At t0 X = 0 A2. Therefore, at t1 X = 0 B1. At t0 X =...
Consider the infinite sequence {0, 1, 0, 1, 0, 1, ...}. Now consider reciting its terms in reverse. To recite its terms in reverse I am only allowed t...
It literally does. No you didn't. You ignored it and just said "when the time comes I say the next number". That doesn't explain how the recitation ca...
According to this, "many philosophers have argued that relativity implies eternalism. Philosopher of science Dean Rickles says that, "the consensus am...
This is what I mean by reciting backwards: If I recite the natural numbers <= 10 backwards then I recite 10, then 9, then 8, etc. If I recite the natu...
Just the ordinary meaning of "start", e.g. "begin". You ask me, right now, to recite the natural numbers in descending order. How do I begin to perfor...
I accept this: P1. If we can recite forward 1, 2, 3, ... at successively halved intervals of time then we can recite all natural numbers in finite tim...
I cannot start reciting the natural numbers in descending order because there is no first natural number for me to start with. That a geometric series...
No, I'm saying that something with no start cannot start and something with no end cannot end. Your argument is effectively "by definition it has no s...
But we're talking about supertasks, not geometric series. That a geometric series is possible isn't that a supertask is possible. Given that there is ...
I don't think it impossible for a geometric series to complete. I think it impossible to have recited every natural number in descending order. My iss...
It does follow. My belief that aliens exist makes the proposition "I believe that aliens exist" true. Therefore, your claim that "a belief cannot make...
Does it? Consider these two supertasks: a. I said "0", 30 seconds after that I said "1", 15 seconds after that I said "2", 7.5 seconds after that I sa...
I haven't claimed otherwise. I have only claimed this: "I believe that aliens exist" is true iff I believe that aliens exist. Therefore his conclusion...
I said this: You responded with this: I gave you this reference: So I ask again: can you prove that it's metaphysically possible for me to halve the t...
Maybe I'm not being clear, so I'll try one more time. Here are two proposed supertasks: a. I said "0", 30 seconds after that I said "1", 15 seconds af...
No I'm not. I'm only saying that "I believe that aliens exist" is true iff I believe that aliens exist. Therefore your conclusion that "a belief canno...
I’ll repeat something I said above: The fact that there is a bijection between the series of time intervals and the series of natural numbers and that...
The lamp starts off. Every time the clock ticks a lamp turns from off to on or from on to off as applicable. Thomson's lamp shows that this leads to a...
Take my explanation of Thomson's lamp above: The important part is in bold. If there is a problem with the button-pressing procedure, which there is i...
The fact that there is a bijection between the series of time intervals and the series of natural numbers and that the sum of the series of time inter...
I don't disagree with a premise. I simply prove the conclusion false, and therefore prove that one of the premises is false or that the conclusion doe...
Your argument is: P1: A stance taken on the truthity of something, is independent of the truthity of that something. P2: A belief is a (cognitive) sta...
I was addressing this conclusion: Nowhere in this conclusion is the term "moral" used. My example of "I believe that aliens exist" being true iff I be...
I'm going to address Benacerraf's Tasks, Super-Tasks, and the Modern Eleatics: The fallacy in his reasoning is that it does not acknowledge that for a...
Well, this is a publicly visible forum so nothing stops ChatGPT from visiting the website and copying what shows on the page. It's possible to stop th...
So you're saying that it's possible to have recited the natural numbers in ascending order and possible to have recorded this on audio but impossible ...
No, it doesn't. Saying that it is an infinite sequence of operations means that it isn't a finite sequence of operations. I'm asking you to make sense...
How can a sequence of operations in which each operation is performed only after the previous operation is performed complete without there being a fi...
It could be anything. The problem has nothing to do with the operation being performed and everything to do with continually halving the time between ...
Argument 1 Premise: I said "0", 30 seconds after that I said "1", 15 seconds after that I said "2", 7.5 seconds after that I said "3", and so on ad in...
After 60 seconds I said "0", 30 seconds before that I said "1", 15 seconds before that I said "2", 7.5 seconds before that I said "3", and so on ad in...
No, we're reciting the numbers in descending order. It's impossible to do, even in principle. The fact that we can baselessly assert that I recite the...
It begs the question. Your premise is necessarily false. Such a supertask is impossible, even in principle, to start. You just listed five rational nu...
Tasks are performed ad infinitum. I never stop counting. There's always another number to count. I'm talking about reciting the numbers. So imagine so...
If supertasks are impossible and motion is possible then motion isn't a supertask. By definition supertasks are non-terminating processes, therefore y...
