A Very Basic Introduction to Logic and Syllogistic Logic

[@baiterfish7901]

Logic seems pretty important to me and understanding logic is probably a good thing to know. So I find it pretty odd that logic isn't taught in schools and it isn't until university that it's taught

[@PhilosophyToons]

And for me, I was pretty lucky to even get a class of it in uni personally, its rare

[@sunbunker685]

That would create a population of thinkers, not emotional, reactionary doers. Goes against the Rockefeller indoctrination system

[@McFlashh]

It’s taught to computer science students in discrete mathematics

[@Nicolas-L-F]

@@McFlashhyep, had it for my maths paper in my comp sci bachelor. Was very interesting to study logic in a formal and structured way. With that said, fuck proofs by induction.

[@peacebuddha96]

That's because the world is plato orientated.

[@dloobster8214]

Bro just explained something 13 min in the same time my professor took a whole semester of college to explain

[@tigrankhachaturian8983]

Except that if you haven't had the knowledge you have, you wouldn't understand it. Give this video to your mom and then see if 13 minutes are the same in value as a semester

[@TheresaReichley]

It’s really something that should be taught in high school - it’s the best tool for critical thought available. If you know logic you can evaluate any arguments given and understand if the logic is flawed. Although I think probability and statistics are important because it helps with science.

[@someonenotnoone]

It's not just seeing flawed logic that is key, it's understanding the limits of valid logic. All the valid logic in the world won't make your assumptions true.

[@TheresaReichley]

@@someonenotnoone that would obviously be part of learning logic. But what we actually teach people to do doesn’t go as far as giving people the logical toolset so they can test validity on their own. Most “critical thinking” goes no farther than “memorize this canonical list of logical fallacies. When you find one, or even think you find one, that argument is invalid and wrong.” Which is why so many people conflate “being logical” and sounding like Mr. Spock. It’s insane to me how often a stupid and illogical idea can be declared logical simply because it’s delivered without emotion. It’s also wild how often the “professional debate guys” will basically win by goading the other party into getting emotional and then the audience sees this as a loss.

[@ludwigwinter6795]

​@@someonenotnoone Exactly. And most political debates, in my experience, boil down to your understanding of reality and your personal values. Logic doesn't help with either of those.

[@unknowninfinium4353]

This went wffs over my head.

[@OnlyScienceRules]

Same here.

[@Greysunderpressure]

I'm doing homeschool and my Dad gave me this video and it helped so much! Thx!

[@spiritandtruth4716]

@ 9:45 - the classical way of formulating this argument would be: BeA - CiB - CoA. This is a perfect syllogism nicknamed ferio where the vowels in the word indicate universal or particular affirmation or negation in order (ie, e = universal negation, i = particular affirmative, o = particular negation)

[@SpareBricks21]

4:50 is an example of the affirming the consequent logical fallacy.

[@damirgabitov257]

In many logic textbooks in chapters about syllogism terms like subject, middle term and predicate are represented as three overlapping circles. Why the circle that represent subject isn't included in the circle, that represent predicate term when we talk about universal affirmative statements? For example , All S are P. In formal logic this statement will have this formula: (x) S x -> P x. In set theory it means, that one set is included (whole set is included) in to another set. But in logic we have another representation: All S are P is the area where S circle and P circle overlapping, and other part of S circle that is out of overlapping area is empty.

Thank you friend

My favorite intro to logic book is, Intro to logic, logic, language and meaning, by LTF gamut

[@guitaristmarko]

This is why the stars work: 7 Rules of Validity: Terminological 1. There must be 3 and only 3 terms 2. The middle term cannot occur in the conclusion Quantitative 3. If a term is distributed in the conclusion, the it must be distributed in the premises 4. The middle term must be distributed at least once Qualitative 5. No conclusion can follow from 2 negatives premises 6. If the 2 premises are affirmative then the conclusion must also be affirmative 7. If one of the premises are negative then the conclusion must also be negative.

[@johnbrownell1]

Took this same class for an easy elective since this all gets taught in week 1 of a math or cs course

[@marellaysn]

i've read the book first before looking for a video to explain it (because even though i think i understand the book, it still sounded a bit blurry to me) then i saw this and this video explained it pretty well, i now absolutely understand the book. so, thank you! I'm still wondering who thought of calling well-formed formulas woofs, instead of wiffs.

[@PhilosophyToons]

Thank you for your comment, this made my day!

[@maxruiter8365]

Amazing!

[@PhilosophyToons]

Thank you max, appreciate it!

[@soumyajitdas1647]

Why my personal beliefs(biases) always dominate the logical mind ? I mean, like I find it hard to believe that all cats are evil, which I believe it's not. And, I find it confusing and my mind goes blank. I usually, never think in this way. Does anyone feel in this way ? I find it extremely challenging to adopt this type of thinking but, I want to. It's not easy for me to think in this way, but I'm positive if I start to think in this way, things will change in my life. I haven't read the book yet, and I'll look into it. Thanks, for publishing this video.

[@visartistry]

well as he said, logic is used to validate an argument rather than test if its true. So it doesnt matter your beliefs in this, if for example felines are evil and a cat is a feline than the cat must be evil. Notice that this is a validad argument but it does start with "IF", so it might not be true but its valid

[@slowgang5000]

A valid argument doesn't have to be true to be considered valid. This is what the difference between a 'valid' and a 'sound' argument. The cat example was given to show and argument can be false and yet still be valid. But its not a sound argument. (Someone correct me if I'm wrong)

[@abrudandorin506]

Thank you

[@LucretiusDraco]

This was very helpful. lol it’s crazy the first vid that showed up when I searched classical logic on YT was Frank Turek. 🤭 maybe ok for someone else but I thought it best to start elsewhere. I will be double checking even u. I was tricked all my life and eventually had to update my belief system so I’m a little skeptical. I think understanding logic will help me not get tricked in the future.

[@alliffmuhamad]

Nice!

[@lormador8493]

You should state that if there is an axiom in which there is a: “no/not” that you then can switch it (no R is E) = (R us not E)

[@peacebuddha96]

Should "pinguins" be lower case p?

This was like a Quentin Tarantino movie. Started off well but then got weird halfway through.

[@groveavenue]

I am disappointed that Logic does not appear to be on the UK's (Scotland and England) national curriculum. When I was at school we badly needed Logic as part of the mental training. Alas! It was not on the menu. It should have been a compulsory subject, methinks :)

[@fabiandulceanu3537]

In my country, we are taught logic in highschool. However, if you wish to continue studying logic, you must go to a Philosophy college (I apologize for my bad english).

My algebra teacher in high school assigned logic puzzles for extra credit.

[@MhlengiNdlovu-m9h]

All math is logic, but not all logic is math. Math is a form of reason. I'm glad you noticed the similarity, though. It just goes to show if everyone is capable of reason and math is reason, all people can understand math if it is approached from the angle their reasoning style. It's exactly why some people can be good at physics and bad at pure math, be a linguistic genius and bad at math. The compartmentalization of school subjects makes it so most don't discern the overlap and universal principles in the disciplines, and so the thought that general intelligence is uncommon is rampant, and specialization is promoted. Nothing is impossible to learn for the average person. The main difference between him and the genius is time, even then, it might not be that great as we greatly underestimate the power of the average mind unfettered from modern artificial constraints. *sigh* I needed to get that out.😊
