    Most forums I've been on that are based around freethought, science and atheism don't have cranks running the show.[/QUOTE]

    Why do you think so?

    I would say it has some pretty bad features, but they seem common to me.

    For example, many (probably most) posters attack other people very frequently, and for no good...

    That is a gratuitous insult. I will appreciate if you avoid the threads instead of doing that.[/QUOTE]



    More critique than insult.

    On the other thread you first condescended. Then you tried...

    You should not be surprised, because most of the leftists in question do not believe that the man did anything wrong in the first place. It's not hypocrisy, for the most part. It's moral...

    Its "Gallifreyan". :)
    But now she's a female. I'm not sure why that tends to bother right-wingers more than left-wingers. Even if (very probably) it was devised from a left-wing perspective, if one...
  6. Poll: Have a good day.

    You proved nothing. You sarted with something from a book and tried to turn into a logical question. Was the goal to prove the existence of an integer ratio that equals sqrt(2)?

    When you said it...

    Poll: That is a gratuitous insult. I will appreciate if...

    It is a question because I am asking "...if we have premises P1,...,Pn, Q1,...,Qm, does (P and Q) follow as a conclusion? ". That is a question.[/QUOTE]

    EB II, just a little more eloquent. I will...
  8. Poll: What "interpretation in terms of mathematical...

    What "interpretation in terms of mathematical logic" are you even talking about?
    I gave a proof. It is correct. It is a standard proof. You claimed it is not valid, and voted so. Later you said "I...
  9. Poll: Three for "valid", two for "invalid". Two vs. two...

    Three for "valid", two for "invalid". Two vs. two if you don't count Learner, who is not saying it's invalid (he said he got it wrong again). But this case is particularly obscure because of the...
  10. Poll: You said the proof is not valid. Now you're...

    It's a standard proof. So, you wanted to know about the impact of having what you believe to be the "wrong" logic on mathematics? Well, as I pointed out, it's pervasive. This proof is not weird, or...
  11. Poll: I'm not saying it's not number theory. :) I...

    I'm not saying it's not number theory. :)

    I linked to the textbook (titled "Algebra 1") because those are the notes of the course by the same name (which I also linked to), and its content is to...

    That's not what the question asks.
    EB[/QUOTE]

    While fast added other points, he did say that it follows, and voted accordingly.
  13. Poll: I studied the Fundamental Theorem of Arithmetic...

    I studied the Fundamental Theorem of Arithmetic (and related matters) in a course named "Algebra 1", and that is standard over here. It's essentially one of the first things one studies in college....

    No it does not. You have to show that if this were a mathematical proof.[/QUOTE]
    I regret you do not understand it, but it is a standard proof. It's the sort of proof you'll get in a basic algebra...

    It is a question because I am asking "...if we have premises P1,...,Pn, Q1,...,Qm, does (P and Q) follow as a conclusion? ". That is a question.
  16. Poll: It depends on how one interprets the premises....

    I am deriving that the next U.K. Prime Minister will not be Jeremy Hunt from P5 "The next U.K. Prime Minister will be Jeremy Corbyn" and P3 " Jeremy Hunt is not Jeremy Corbyn". But you're right it's...

    Yes, but left-wings in the West seem mostly bent...

    Disagree--in much of the world there's plenty of space for enough solar cells. The problem is the lack of meaningful storage options.

    Until (and if) such come along, though, we should be going...

    The conclusion follows necessarily from the premises (maybe you misread?): From P3 and P5, it follows that the next U.K. Prime Minister will not be Jeremy Hunt. From "the next U.K. Prime Minister...
  20. Poll: How would the fact that the premises contradict...

    If the question were not whether the argument is valid, but whether the conclusion follows from the premises, would you not say that it does follow?[/QUOTE]
    I would say that the conclusion does not...

    No problem, at least this is a more interesting discussion than Speakpigeon's stuff :D - though if you want to know, it turns out this whole thread was not needed, since Speakpigeon replied in the...
  22. Poll: To everyone:

    From

    P3 - Jeremy Hunt is not Jeremy Corbyn

    and

    P5 - The next U.K. Prime Minister will be Jeremy Corbyn,

    we derive the following conclusion:

    Thank you to say whether you consider this argument valid or not.
