Aristotle - The History of Logic

[@gofaonepaul]

So greatful for this! At the end of each slide, I consistently got that physical sensation in my mind that signfies a kind of alignment I associate with understanding. Please, for the sake of truth, DON'T STOP MAKING VIDEOS!

[@ExistenceUniversity]

As a content creator myself, who receives these kinds of comments on my stuff, I'd ask that if you don't want this creator to stop, I suggest you pay him. It's really nice being told "Don't stop" but what you start to read after a few of these comments is "Don't stop entertaining and educating me for free!" You want more, I suggest paying for more.

Incredibly useful and easy to follow along with. Thank you.

Glad to help!

[@sciencefordreamers2115]

Thank you, very useful!

What a great topic.

Nathan. Your content is awesome!!! 💜💜💜

[@oldsachem]

Thus, by Aristotelian rule of existential import, no empty set in math can be contained in any other set.

[@veracruz3878]

awesome!!

[@jakecarlo9950]

Very good presentation, thank you, hope more will follow soon. Also that you found whoever was throttling that squeaky toy and gave him what-for... :)

[@nealshore212]

Really interesting video. The topic would make a great podcast... You explain theory well. Better then my uni tutors did. Nice to meet you today on the nature reserve

[@DigitalGnosis]

Oh hi there! What were you studying at uni?

[@nealshore212]

@@DigitalGnosis sport and exercise science. I majored in bio mechanics but did enjoy philosophy in sport where in we discussed logic of actions with a bias to team decision.

Informative.

[@GaderineInsomniac]

Am looking forward to this, Nathan. Will you be covering the book, __ Fuzzy Thinking, The New Science of Fuzzy Logic__ by Bart Kosko?

[@DigitalGnosis]

I'll definitely be covering McCulloch and Pitts logical analysis of neural activity at some point. Whether I go past that into non monotonic logic etc is still up for debate! Let's see how it pans out!

[@samdog_1]

Kant only lived 1784 to 1804? That means he died at 20. Try 1724 as his birth year....

[@DigitalGnosis]

Whoops - didn't catch that. I've put in a note to correct it!

[@Linguistie]

damn ok I might actually dig that kind of content. couldnt be bothered reading it myself, but why not listen would be nice if you applied a noise filter tho

Есть ли смысл рассматривать какие-то варианты AEIO-описаний, если после устранения архаичных ошибок силлогистики ПРАВИЛЬНЫЙ ВЫВОД ЛЮБОГО СИЛЛОГИЗМА ЛЕГКО ВЫЧИСЛЯЕТСЯ АЛГЕБРАИЧЕСКИ? :-) Подробнее - см. 06-04.

If someone steals one of the wheels of my bicycle, is it no longer a bicycle?

[@DigitalGnosis]

Perhaps a bad example but nevertheless stolen from Isaiah Berlin so you can take it up with him! ;)

[@ares106]

@@DigitalGnosis I don't think the example is bad, my post was more of a critique for the idea of essential features. I feel like the ways humans tend to categorize and fluidly use ways to define objects, creates a lot of edge cases which make the idea of essential features seem obsolete.

[@DigitalGnosis]

@@ares106 yes I see. I think there's something about being a two wheeled vehicle that is essential to a bike... Maybe that involves ideas of potential and function. I agree that providing strict necessary and sufficient conditions for any concept is almost impossible!

[@spacedoohicky]

Wouldn't it be a bicycle with one wheel? Because the essential properties apply to how it's supposed to be used, and not how it appears. You could say that it's properties exist contrary to the condition of it being beyond repair. So it's either what it can be used for, or it's literally trash. I think this is how machines like this are commonly thought of. It ain't what it's supposed to be when it absolutely cannot serve that purpose anymore. So maybe the essential properties result from not not being useful as a bicycle for good. Though, I get what you said here is a response to what was said in the video.

[@HyperFocusMarshmallow]

Two wheels are essential for a bicycle. Is it essential to a bike though? 🤔 are two wheels essential to a “velo” (French bike) or “cykel” (Swedish bike). The plot thickens... even tricycles and unicycles are sometimes just called “cykel” in Swedish.

[@Syllogist]

Great sorry, but… CONCLUSION FOR ANY SYLLOGISM CAN CALCULATE INTO ALGEBRAIC FORM. You demonstrate good scheme for logical square… but… Seems for your example EIO (41:45): 1. No M is P 2. Some S are M - - - Yours conclusion - - - 3. Some S are not P Algebraic calculation: 1. No M is P (M’P) 2. Some S are M (SM+SM’) - - - Calculation: ((М’Р)*(SM+SM’))/M = (M’PS)/M = PS = SP [«/M» - it’s delete middle term] - - - 3. There is P so as S [meaning only as «M’»] (equivalent: 3. There is S so as P) This example so as many moduses of classical logic (47:20) is invalid. More time sorry… (detail: 08-04.ПРАВИЛЬНЫЕ СИЛЛОГИЗМЫ ДЛЯ ДЕТЕЙ И АКАДЕМИКОВ-1 / Valid syllogisms for children and academics-1: kzbin.info/www/bejne/h2G2ZKt_bMtjqdE ) :-)

[@loriw1234]

Your first slide has a typo. Aristotle's logic needs the apostrophe to denote it's possessive.

[@operaguy1]

3:50 "...overthrown..." Uh-oh. Should i bother with this vid? I suppose you think Einstein "overthrew" Newton.

[@DigitalGnosis]

I don't care if you bother with this video or go and have an asphyxiwank

[@ExistenceUniversity]

If you are so wise and knowledgeable, why did you feel the need to watch this at all then? Your high horse smells like a bull to me.

[@mind_onion]

But Aristotle said heavier objects fall faster than lighter ones, so he couldn't've been that good at logic ;)

[@gerededasein1182]

However, see Carlo Rovelli's article, "Aristotle's Physics: a Physicist's Look" for an interesting discussion of that very proposal: Aristotle's physics "is commonly said to state that heavier objects fall faster, when every high-school kid should know they fall at the same speed. (Do they?)" (opening paragraph).

[@mind_onion]

​@@gerededasein1182 The reason I bring it up, is there's a simple logical problem with heavier objects falling faster, despite this theorist's work at apologetics for the ancient understanding: If I have two objects, one heavy and one lighter, and the fact is that they fall at different rates, what happens when I tie them with a rope between them? Does the lighter object arrest the fall of the heavy object and make it fall slower, or does the combination behave as a heavy object and fall faster? It seems as though both these are true! A clear logical contradiction. One that, if memory serves me correctly, is remarked upon by Galileo And, indeed, despite the apologetics in the article referred, best I can tell, skimming it, its bringing up terminal velocities and such, plays into the areas where these serious issues are most apparent: by affixing a parachute to a man, do we arrest his fall or do we make it faster? It depends not on the mass of the chute, which could be deployed or not deployed and thus get either result. The paper is kind enough to concede: "Humanity had to wait for Bacon and Galileo to learn the power of directly interrogating Nature" in other words, actually doing science.
