Full time smug prick
Right? This is what is also complete hypocrisy on Republicans part. On one hand, they (erroneously) equate trans with surgeries when they want to condemn youth healthcare. But somehow all adult trans people are no-surgery self-identifying “men in dresses”.
No one is attempting to prove bleeding P->Q here.
If P -> Q and P, then Q
Sure, and when ~P^Q, then P->Q is still not false, and you can further use it in a proof, in the context of other given statements.
This was never presented as a method to show that P->Q, which arguably can only be shown with data.
With all due respect, get your head out of your arse and read this from what I posted:
While modus ponens is one of the most commonly used argument forms in logic it must not be mistaken for a logical law; rather, it is one of the accepted mechanisms for the construction of deductive proofs that includes the “rule of definition” and the “rule of substitution”.
Emphasis is mine. I cannot scream hard enough to get this simple message across to your flipping head. You are reading it wrong, and if you had done one class of prepositional calculus you would have known, therefore you haven’t.
As for your foundationalist pursuits, most of science advances without getting back to the foundations, just as calculus was in practical use long before it was formally proven. So you see a person (OP) struggling with basic conception and composition of his argument, let alone the formal expression, and you raise the bar to the level of logical foundations of mathematics? If not dishonest, this is utterly unproductive.
Quine is the most sane person among your lot. And righteously followed by Thomas Kuhn.
Given A and given B, with literally nothing else, prove A -> B.
That was never the task at hand. You are projecting your belief system so hard you cannot even parse the arguments at a functional level. Yet, after an hour or so, suddenly 4 more vote me down, and only in this particular thread. (Since the rest of the comments in the whole post are unaffected, even mine? What the fuck did you go to your philosophy of science SimpleX chat and called for back up?
For the last time The truth table does not mean that A->B is “proven”. Obviously you have never done propositional calculus on pen and paper, because this misconception is literally worse than OP’s ravings.
You postmodernist you
I stand by the comment. Bringing up Gödel in polite conversation should go straight to the site-wide banable offenses.
Good luck!
This attempt to patronize is futile. You proved you were in bad faith, and I wish not to continue this discussion.
We want to prove A -> B ergo given A and B, A -> B.
Still failing to see that we aren’t proving A -> B, but getting its truth value within a proof.
OP brought propositional logic to a relativistic conversation. My goal was show why that’s a bad idea.
I think your goal was the equivalent of what any postmodernist does in deconstructing any given field:
By the same coin, all the other logical fallacies go out of the window, together with boolean logic and what have you. Even the valid ones.
It’s now an axiom that A and not B cannot be
How so?
Remember, we started with the assumption we could prove A -> B by negation, not that A -> B was guaranteed.
It is rather that the fact that people who do have something to hide will probably use encryption cannot be refuted by an instance of someone using encryption without having something to hide.
We waved our hands and said there’s no way for that to happen.
This is textbook modus ponens, sorry if you find that disturbing.
you are assuming some sort of framework that allows you to build these truth tables from real life
This is unproductive and eventually relativistic. I can’t fathom how you dare bring advanced topics of math/logic fundamentals in a discussion like this. We are talking the kind of stuff that takes 200 pages to prove 1 + 1 = 2, and why it is not correct, or absolute. What is the purpose of that level of meta in a discussion about flipping privacy?
Pregnancy, abortion seeking, sexual orientation of clergy, being trans, all have become matter of life and death level reasons for caring about privacy.
Ah, another one: insurance company might profile you as XYZ subcategory and discriminate against you.
“Yes but you know what data brokers are hiding from you?” I haven’t tried this one, but I will.
In modus ponens you have four cases:
| A | B | A -> B | |
|---|---|---|---|
| a | 0 | 0 | TRUE |
| b | 0 | 1 | TRUE |
| c | 1 | 0 | FALSE |
| d | 1 | 1 | TRUE |
Here, A is “Having sth to hide”, and B “Caring about encryption”. Obviously case b says that although people having something to hide seek out encrypted methods of communication, it is logically accepted that there might be other reasons, even unknown. A more silly example is this: the grass is wet does not necessarily means it has rained. There might be other reasons. But this does not mean that rain does not make the grass wet.
To sum up, the OP could have just said that. It does not change anything anyway. You can’t beat a propaganda apparatus with this “fallacy talk”.
It is widespread propaganda to make everyone who uses private and encrypted tooling as potential criminals. Encrypted chat is not sth clean cut kids do. Simple as that. It is a pushed narrative by those who don’t want encryption.
Everytime a superficial opinion is so strong that is robust to constant debunking and perpetually reprises, it is typically a propaganda apparatus at play.
Having said that, your attempt to appeal to logic is utterly futile, and also in this particular instance, done badly. Mostly because of the imbalanced and non-sequitur rendering the text unintelligible.
This is some BS. What the OP haplessly tries to say is simply modus ponens. What Gödel are you talking about.
I won’t validate your line of questioning my personal beliefs, since there is no way of winning this. It is dishonest and weaselly. Nor will I tolerate the various associations and insinuations behind your question, which have my ml membership as a starting point.
I have nothing to prove to you. My post history is right there for everyone to see, and it is also a recommended reading for normies. Tell me if you find sth there. Do that for a significant sample of ml users and present your data, if you want to prove a hypothesis they are pro-Putin or pro-China.
You people beating on the dead horse of “lemmy flagship instance bad commies” is sickening really.
I will not consent to you putting me on the spot as some kind of ml specimen, nor I want to stand out and say “I am different”. I already stated, I am an anarchist doing just fine in ml, and I have my own questions about defederation and why this instance tribalism is going on.
Yet you guys keep responding to me as “that ml user”. This is unacceptable. This is the type of trolling that you accuse “some” instances of, and this shows that there is something fishy about this whole ordeal.
That’s because you stoop too low.
I hope you get the help you need.
It started as a meme but this ml-hatred is a conspiracy cult at this point. I have no interest in defending no Stalinist or whatever, but I will not succumb to this false logic of judging people for signing up to the flagship instance, home to major Linux, Open Source, and Privacy communities.
In fact, I think spooks and trolls spreading disinformation under privacy and anonymity questions is a greater problem than the spectre of the bad ml/grad/hexbear user. Now, you folks are adamant that the instance someone signed-up for, often blithely, can accurately judge their character.
This is superficial and moronic and you only come up with ad hominem responses for me pointing out that your logic is abysmal. Plus, it might really hurt to admit you are wrong, since shitting on the flagship instance seems to be an unhealthy obsession for you people.
tries to frame itself as it is for traditional Christian values
Nazi Germany had a complicated relation to religion. Although promoting relations with Protestant clergy in the pre-war period, there were conspiratorial tendencies in the Nazis either Nordic-washing Christianity or looking toward some kind of self-styled supremacist paganism, which was popular with the SS top leadership.
In the end of the day I don’t think it even matters though. The American Christian-nationalists are the structural equivalence of the Islamic State in that they want to undo secular political entities and unravel modern institutions. It doesn’t matter if some of them belong to some sinister cult. They will do as much evil, and they are not different from mainstream 1930’s Nazism for that matter.
this one is easy to attack
Exactly. Trans representation was as bad as it already were, and then instead of some positive news coverage what you’ve got? Like 700% upward vilification and stigmatization, with the support of many center and center-left media, and huge institutional and billionaire support.
Man I am telling you, there is another Holocaust in the making and people will not believe it happened when it is over.
That book you suggested by this professor On Tyranny is indeed a compulsory reading at this point for every person caring for Western democracy.
What I said was not to mean that “not having a penis” is a prerequisite to enter a toilet. This is so complex to put in simple terms, because what TERFs say is an inconsistent cocktail of hateful ideas, that contradict themselves. But no one is examining genitals to enter any toilet. They just appeal to plain old cisgenderism, “people who look like men must have dicks and people who look like women mustn’t, because these are the two natural categories and I want to be able to put anyone neatly into them, except some freaky accidents of birth”. Their actual problem is that legitimization of transgender individuals threatens the very core of this cisgenderist ideal, which only lead to the corollary that trans people are not natural and should not exist. I intended to write sth else entirely but this is the cornerstone of the whole discussion, that cisgenderism is the substrate and breeding ground of transphobia and perhaps we should start discussing in these terms instead.
