Aristotelian Logic

We just learned a bit about Aristotle and his philosophy, but he was also the first figure to truly establish logic as a field unto itself, and he developed many of the formalities this field still uses today. Types of sentences, induction vs. deduction, modal logic, there is a lot to unpack here, so let's dive right in!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

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

[AndyRhodes]

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.

What a lifesaver, and thank you. My Professor is One Note. He and his books put me to sleep. I finally understand A, E, I, and O.

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.

Actually, there are immortal YouTubers. Neuro-sama, MotherV3, and probably many more.

P1: Some YouTubers are AIs
P2: All AIs are not alive
C1: Some YouTubers are not alive
P3: No non-living thing is mortal
C2: Some YouTubers are immortal
P4: Dave claimed that all YouTubers are mortal
C3: Dave made a false statement

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.

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.

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! 🙌

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

[cyan]

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

[MJAli]

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

Hello Professor Dave, I have benefited a lot from your presentation, thank you, but I have a note on the AAA pattern in the example mentioned in it, the result does not follow the premises

[donchristie]

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

[ignacioleikis]

Hi Professor, first let me say that your videos are awesome!
My question is what about those cases where Premise 1 is True, Premise 2 is True but the Conclusion is False? Please clarify.

Thank you so much!

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?

[italiandarthvader]

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.

[hailsagan]

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

[Arabian_knight_]

You explained it better than my teacher dam

[DeepSpace]

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.

[GreggMikulla]

All this is well and good, but I tend to have trouble following Aristotle's sentences: **if M is predicated of all O, but of some N, then then some N is O....** and on and on, swinging back and forth...it's hard to .memorize
