Aristotelian Logic 

That is by far the clearest explanation of Aristotelian logic I've ever heard. Thanks Dave.

I have watched at least thirty of your videos over the years. Great work, Dave! Very clear and succinct. This video was excellent. In two weeks, I will begin teaching a philosophy course to a high school student who is enthusiastic about this subject. This video will be quite helpful.

This is a great summary! I teach mathematics and logic at a community college, and this video would be great to add to my supplemental materials for students. Thanks, Professor Dave! 🙌

Symbolic Logic is a great course in college. I think everyone should be aware of how important it is. It wasn’t easy for me. It’s so valuable. Question everything.

Dave's videos provide me with a lot of information and challenges. By the way, I love Dave's book. I read it every year as my Christmas gift.

I didn't quite understand how the chain of reasoning in deductive reasoning is used step by step so thank you very much for that. Never stop what you do, and I can't wait for your video on frege.

Thank you for this series!

This video is superb , thanks Dave

Thank you for your work❤

Thank you ! A good test for the validity of syllogisms is the Gensler's Star Test... (Although I heard that it doesn't work with all types of syllogisms).. But it is enlightening to know why it works.

Good stuff! Thank you!

Actually, there are immortal RU-vidrs. Neuro-sama, MotherV3, and probably many more. P1: Some RU-vidrs are AIs P2: All AIs are not alive C1: Some RU-vidrs are not alive P3: No non-living thing is mortal C2: Some RU-vidrs are immortal P4: Dave claimed that all RU-vidrs are mortal C3: Dave made a false statement

Thank you... You did great...

The debate was the best one this year so far, it got a bit personal but fun.

thank you so much for this !!

Every election cycle, we are reminded of the lack of logic we possess

Old McDonald had a farm Negative-universal affirmative-particular Negative-universal affirmative-particular Negative-particular

Professor Dave, are you planing on uploading the debate you did with James Tour?

Dave thank you❤️

OOT Professor Dave, is syllogism related or similar from _categorization_ our biased minds tend to sort and generalize things or are they completely separated from the topic? Like this Aristotelian logic is talking about public logic like objective universal facts such as "raccoons aren't wolves" and categorization is talking about social psychology based on our personal judgment from information (and misinformation) we gathered?

Aristotle's logic is terminus logic given if ends in terms and thus the division of logics is between the terminus and the non-terminus, whereas "propositional", "symbolic"( both useless for division as most logics of in the history of the West has employed the symbol from the alphabet for the purposes of particular demonstrations. Take them as describe logic, for abundant use of arbitrary symbols is the attribute of modern logic) modern( very useful for the division with non-modern logic. Very useful as we get insight knowledge of historic unfolding where knowledge is divisible in other disciplines as well. Modern Physics and it's non-modern counter part, modern Grammar and it's the modern.

On a side note,kandiss taylor from georgia who ran on the platform jesus,guns,babies did a video w david weiss,and she's now a flerf. Idiocracy was meant to be a cautionary tale

Thanks Dave :)

If you shift a bit left does it become true? How about base 2 math and how we use it.

7:49 I assume bayesian probability is the recent development of modal logic, right?

Nice video. I have a few remarks (see below, if interested) but apart from that the video was very lucid and cut-to-the-chase. Firstly, I think the argument at 6:05 isn't valid (what would make it valid is if the second premise were instead "All mortals are human", rather than "All humans are mortal"). Not sure whether that is important, though, since it still falls under the same mnemonic encoding, but I thought it might be helpful to point out. Secondly, Aristotle's principle of non-contradiction is not _just_ that something cannot be and not be, at the same time, but more precisely that this cannot happen at the same time _and in the same respect_ --- e.g. something can _be_ red and _not be_ yellow, but red and yellow are in different respects of colour. (Usually you'll find this emphasis being made by scholastic philosophers, like Aquinas, during when the works of Aristotle were being translated and disseminated around the world.) Finally, I think it would have been useful to mention that Aristotelian logic works with sentences which have a _single_ predicate and a _single_ subject only (compared to the multi-subject and multi-predicate logic we work with today, largely developed by Frege and also Boole); often young philosophy enjoyers learning Aristotelian logic for the first time find it very clarifying and useful for argument analysis, but it shouldn't be the curriculum for how to do logic, since there are more precise and more general alternatives (which is why I appreciate the video's historical and hermeneutic flavour, I think that's the best way of presenting this information). At any rate, though, very good video!

Can you make a video debunking fools like graham hancook who think the coordinates of the gizeh pyramid correlate with the speed of light because the egyptians surely used metric back then?

Kindly you give an on non Aristotelian logic ??

Frege’s Analytic philosophy challenge Aristotlelian logic rather it’s built upon it but expands it using mathematics . Aristotles laws of logic are universal and any attempt to disprove them would already require the person to presuppose it .

_Half a bee, philosophically_ _Must, ipso facto, half not be_ _But half the bee has got to be_ _A vis-a-vis its entity, you see?_

You explained it better than my teacher dam

Based Aristotle

I thought the ten categories were for subject terms, not for predicates

2:55 and to think I was being taught philosophy by a Birdog this entire time

good video but at 6:17 the example given didnt follow as the predicate being mortal didnt change to being an operator. all humans being mortal and all youtubers being mortal doesnt mean that all youtubers are humans. it would have to be that all youtubers are mortal and all mortal things are human to follow

If Macdonald was old, then he had a farm. EIEIO. QED.

In quantum physics, things are and are not at the same time, as opposed to what Aristotle said.

Off topic, but I'm new here and just wanted to say you rock. I just watched the "debate" with tour and Yourself. I've never seen either of you before. You're a god damn legend. I appreciate those willing to call out those who deceive others. Also, I love your "barney style" breakdowns. 👍🏾

Funnier is 1. Every dog is human. 2. Prof Dave is a dog. 3. So Prof Dave is human.

Fan of DC 😊

If I say "Everyone named Professor Dave is a nice person", and there's only one Professor Dave, is this a universal or particular statement?

JT debate upload when

6:16 I know that you probably used it randomly, but I do want to point out a funny little. The conclusion itself isn't completely true in the age of AI RU-vidrs.

👏👍

James kept screaming over Dave and saying "show me the research" and ignores any of the papers. loolz

Im a perinatal peripatetic with a periwinkle pigmented perineum.

Schrödinger entered the chat 5:52

Man, are you joking about "Barbara" sentence? How did you deduct from: P1: All RU-vidrs are mortal P2: All humans are mortal that C: All RU-vidrs are human? Equally you can say that "all humans are RU-vidrs" :D

Won’t you be releasing a video of your debate with James Tour?

Read nyaya and navya nyaya ancient but most sophisticated logic body. ❤

Are AI RU-vidrs both mortal and immortal? Mortal in the sense that they can be turned off, and immortal in the sense that they don't have a necessary termination (as humans still do).

I miss "He knows a lot about science stuff, professor dave explains" whenever you make a science video pls keep that intro

killing others is immoral war involves killing war is immoral ALL WAR

Where's the debate?

Things are always and not at the same time

1st

Dave is an Ape. Ape go bananas. Dave go bananas.

Wheres the tour debate mr dave?

Dave I just watched you're debate..interview ...with Jesse Lee Peterson and I was shocked how you were being fired at ..you did a good job and there is no way you had to justify yourself at any point in that discussion..I'm disgusted at Jesse for the way he treated you totally disgusted...that was out of order it's not you're fault for the way he sees life and expected you to answer his deluded views on Life...your ok Dave
