Only people who haven't studied any logic at all say this.

Logic only requires minimal study to be used and understood correctly. It's like hygiene, you don't need to shower for an hour, 5 minutes is enough

Well did you study any logic as part of the math? Any Euclidean geometry with proofs for example? Or symbolic logic?
>explains why I don't respect logic as a topic in and of itself
No it doesn't, you need to elaborate.

The topic is the fact only people who haven't studied logic say logic is innate and that they therefore don't need to study it.

21 rules for direction of the mind is the best primer for logic. It is very short, concise and goes over the essentials of logic.

Yeah the most important thing that people seem to miss with logic is how to know if a certain statement is true, following from premises made. The other important thing that is ignored is how disproving a statement with a single counter example is much easier than proving that the statement is true in general, especially in abstract matters like mathematics, and completely impossible when it comes to the real world. That's why logic isn't that important for most people, it only practically pertains to rational entities like words, numbers and geometric figures.

The amount of times I've seen someone claim to have debunked an argument or bested someone in a debate with "logical thought" and their arguments are the most illogical wishful thinking with tons of unconsidered assumptions shows that logic is not innate.
To tons of people, "logical thought" means "common sense" and "intuitive".

Cool, I'll look into it. Here's another old book: https://en.wikipedia.org/wiki/Port-Royal_Logic
There's also Symbolic Logic by Lewis Carroll.

You'd probably enjoy Boole's books on logic if you're reading it historically

Obviously Frege too but I'm sure you've already read at least the Begriffsschrift

No. You're the one with the positions that you majoring in math explains why you don't respect logic as a topic in and of itself, and that logic only requires minimal study to be used and understood correctly. You need to back it up. Logic is deeper and broader than math.
>isn't that important for most people

Yeah, most people use words.

To represent reality. Proving something formally in the hope that the proof also applies to the underlying reality it represents is delusional. The domain of logic is much more limited than what intellectuals who rely to heavily on rational would what it to be.

OMG if you didn't take the analysis super premium pro max course you know nothing about logic or mathematics. Truth is most of mathematics, and logic for that matter, are circular if you study them at a fundamental level. Being "more" logical or being a grad student won't give you a "deeper" understanding of anything. It's mathematics, not philosophy you retard

Sounds like you only learned about logic streamlined for use in mathematical application. Logic goes beyond that. Grammar, logic and rhetoric were removed from public school but they study it in yeshivas and in Freemasonry.

It has absolutely no practical application when it comes to human reasoning you pedantic goblin. Being a grad student means you specialize in that subject, which automatically excludes all other mathematics students who are just undergrads or graduate students in other very narrow fields of study. Literally the opposite of something that you suggest should be "common knowledge".

A math PHD that doesn't specialize in that very specific field of study isn't any more qualified to talk about this topic than an undergraduate according to you own pedantic logic. It doesn't have anything to do with you education level. Truth is this is not a peer reviewed magazine where we suck "expert" cock you pathetic academia cuck.

Getting back to the topic of the thread, you only studied this narrow subfield of logic, so you know nothing about the rest of logic, and yet you have an opinion about that rest which you didn't study.

Again according to your own standards, who knows about "the rest of logic" apart from some very modern, very recent extremely specialized scholars ? It ties back to OP's original message, who seems to want everyone to be a PhD in logic or philosophy, which is obviously completely useless, retarded and gay.

I am OP and I made the post you replied to. This discussion is pointless. You know about a very limited very specialized part of logic, and nothing about the rest. Your opinion about the rest is not interesting. All you have done is prove the thesis I made in the OP, that people who haven't studied logic say you don't need to study it. You haven't studied any logic beyond the narrow specialized part of it in your math, and you think virtually nobody needs to study any of the rest of logic. You're talking about something you know nothing about.

Why do they study logic at yeshivas and in Freemasonry?

Asking for the third time now, did you study Euclidean geometry with proofs?

OP again, I'm not that guy but it's bullshit that only "some very modern, very recent extremely specialized scholars" or someone who is a "PhD in logic or philosophy" know logic beyond the specialized part you studied. Yes, today very few people learn any logic. But again, they study it in yeshivas and in Freemasonry, and you can self-study logic. Also logic used to be a part of public education but was phased out during the first half of the 20th century, with the nail in the coffin being the removal of Euclidean proofs with New Math in the 1950s. Are you aware of the classical education, the seven liberal arts, the Trivium and the Quadrivium?

Not an argument. They study it because it gives you power over yourself and others. It was removed from the public because it makes them manipulable.

When they say they studied "logic" in your screenshot, they obviously aren't talking about some specific "modal logic" the other "graduate level" poster was referring to. They most likely only studied an even more limited set of things than what your average math undergrad has studied, which is modus ponens, inference rules and all that crap. Again, you clowns need to acknowledge the fact that logic has formally existed as a subject of study for thousands of years now. If you limit the knowledge of logic to the last developments in the field in the past 100 years, you're just a pedantic, clueless and off topic.

I'm not going to go back and reread the bullshit you and the other guy were talking about in your stupid tangent you were going out on. Stick to discussing the OP topic or leave. I suggest you just keep quiet because you have nothing to add to the topic. Go study logic, you need it.

Can anyone talk about the logic in 5.9 of elements? It's one of the shortest propositions I've read in the book, is saying "because it is" and "because it does" all the logic needed? And can this logic be transferred to image board conversation as well and does such laconic logic insult effort posters and people who use long winded rhetoric?

suppose A:C = B:C, then A = B
because if A != B, then A:C != B:C, but we already supposed A:C = B:C ("but they do" part), therefore A = B.

likewise, suppose C:A = C:B, then A = B
because if A != B, then C:A != C:B, but we already supposed C:A = C:B ("but it does" part), therefore A = B.

this is just proof by contrapositive. ie. you show X implies Y by showing that assuming not-X, you get not-Y.
