This is one of the best educational videos I have seen on you tube.

[@jakelm4256]

There are videos like those at the Classical Liberal Arts Academy which go through Aristotle’s works line by line which are exponentially more educational.

[@Israel2.3.2]

I just learned that David Hilbert gives us a systematic derivation of the traditional Aristotelian inferences using the monadic predicate calculus which I believe was taken from Russell and Whitehead. If I get bored enough I'll make an attempt at exposition here because it seems instructive. See Hilbert and Ackermann, Principles of Mathematical Logic 1928

[@frankjaeger2565]

Frege is the father of modern predicate logic

[@Israel2.3.2]

@@frankjaeger2565 It would be interesting to track the development of predicate logic from Frege through Russell/Whitehead and again through Hilbert, Ackermann and Gödel. In what sense is the predicate calculus found in Gödel equivalent to that found in Frege? I'm still struggling through chapter 3 of Hilbert and Ackermann so I still lack a proper understanding of 1st order predicate logic, nevermind logic of higher orders.

Logic is dead, because physics has shown spacetime is dead. Live with it.

Love this content! 👍🏻

The title reminded me when Gumshoe asked Edgeworth what Logic is.

Philosophy overdose, spill the beans! Where do you get all this philosophy gold? :D Also might you have the video of RM Hare on moral philosophy in The Men of Ideas interview (and in English)?

[@bpatrickhoburg]

I found it once, Jack, via Reddit. There’s a thread that will take you to the audio (eventually).

[@Philosophy_Overdose]

@@bpatrickhoburg I'm pretty sure I know what you're referring to and it isn't the interview with Bryan Magee, but some other interview with Hare that is grouped together with audio from the known Bryan Magee interviews.

[@bpatrickhoburg]

@@Philosophy_Overdose thanks for the clarification man. When I wake up for a cigarette and coffee your uploads get my mind ready for work. Thanks again. I don’t even care what it is for the variety helps me avoid hyper-specialization, a tempting option for philosophers.

[@edgargonzales9031]

@Philosophy Overdose Hey I love your vids! By any chance do you know when you will upload a vid of Camus about the meaningless of life. It was in your previous channel. A women in black and white vid talked about his philosophy. There were parts where music played in the background with people dancing reflecting the absurdity and meaningless of life. It was an amazing vid. Thank you for all the knowledge you share.

[@jamesnaughton5657]

There are much better ways to convey the Square of Opposition than to describe it.

[@Value_Pilgrim]

A graphical approach might have been better

[@bpatrickhoburg]

Excellent upload man! I don’t recall this video before they took everything down. I have to make a small critique. Logic or analytics, who cares? Aristotle would have likely shot down the emphasis given to the etymological explanation given here. He also fails to mention that time is a key problem pertaining to the context of de interpretatione. Propositional logic operates with a background assumption that time passes in the form in which we think and measure it. Aristotle is suspicious about this assumption, which is why the ship example is so puzzling to this day. If you reduce it to the problem of the excluded middle you miss the temporal dimension of the problem.

[@frankjaeger2565]

Italians care too much about etymology (I'm Italian)

[@James-ll3jb]

"A is A and not non-A". But that something is itself does not entail that it, for that very reason, cannot be not-itself; for nothing can be not-itself irrespective if it is established it is itself or not.

[@buddylandry4788]

Who’s foot is that?

[@James-ll3jb]

Aristotle's Law of Excluded Middle: "A is either B or not-B. A third hypothesis is not given." (Tertium non datur ) Then how can Kant and everyone subsequent to him be correct in asserting that "existence cannot be a predicate," if this rule, that "A is either B or not-B" is absolutely true? To say "A must already be in existence to speak of it" is not an answer, for then making a predicate out of any existent thing A would merely be redundant, not false nor even wrongheaded. And to say, "you cannot speak of the existence of something that exists" is only tautalogical. The thinking too, I think, was that 'existence' is not a property of an existing thing, that is to say not an extrinsic feature or inherent quality of a thing that could properly serve as a predicate. But why not? Surely existence is an extrinsic feature of any existing thing, known epistemologically of it as is any other condition or attribute it possesses; and to deny existence the status of 'inherent quality' of any existing thing seems papably absurd for identical epistemic reasons. I therefore conclude, over against all modern philosophy since Kant's "Critique of Pure Reason," or his "Prolegomena To Any Future Metaphysic," or wherever the hell he so initiated this seemingly indelible heresy, that to the contrary, existence CAN be the predicate of any existing something or other, falsely ascribed if and only if said something does not in any way exist.

Proposition : Amazing to me how few people have viewed this video! Conclusion : Tells me that most people have no interest and no use for logic! Is this a logical conclusion?

[@Shadowman4710]

Yes.

[@H.J.G]

Here's a question for you: what do the chains in Plato's cave represent? Were its prisoners chained by a) their ignorance of the truth? Or b) their belief that what they took to be the truth was in fact the truth? If a) then you have indeed reached a conclusion. However if you think b) then it could indeed be the case that people have not seen this video because they simply do not know it exists. It does not mean they have chosen not to show interest. I'm sure there are many who would show interest if only they knew it existed.

"If I say all men are mortal then it is true some men are mortal." ~ Gabriel Ginnantoni on Aristotle But if ALL men are mortal then not merely SOME men are mortal. So "all men are mortal then it is true some men are mortal" is true only if the statement "Some means less than all" is not true. For if it is, then "Some men are mortal" is not derivable from "All men are mortal," for it is not the case that "some" being less than "all" is true.

[@IndustrialMilitia]

"Some" according to Aristotle's Term Logic means "at least one".

[@James-ll3jb]

[@batranelwadie6294]

All beings are philosophers

[@Shadowman4710]

That's a proposition. Is it true?

[@H.J.G]

All people are beings but not all beings are people. Therefore if all people are Philosophers then not all Philosophers are beings.

How far back has religion stunted the wide spread understanding of the human condition? ALOT

[@lorax121323]

Religion is what made us obsessed with finding meaning and purpose in lives instead of plainly acknowledging that meaning can only be assigned to concepts formed by the human mind, and that only actions carried out by a conscious human mind can have a purpose.

[@WhateverWhateverwtghvh]

lol you fool, humans foolishly try to understand Gods design, but will never understand it 100%. just like with logic and morals, 2 values embedded in us, that atheists cant even prove where they came from. just be thankful next time you get to discover and try to figure out God's design, we dont need to hear your bitchin. religion is the human condition

[@suntzu7727]

How about your read an actual history book instead of Christopher Hitchens? Actually it was Christians, like the Scholastic Philosophers who preserved the science of logic and perfected it.

[@GIF_CANCEL]

If you thoroughly and truly understood within yourself how idiotic and ignorant your statement is, you would be terribly embarrassed as of the most lowly and most contemptible of mental midgets. You mention religion. Define your term. Define religion. I suspect you have no idea of what religion really means.

[@GIF_CANCEL]

@Alan Stratmann This is a childish and small minded circular argument. It is a lazy, incomplete, and selfish thinking process. If your mind and its products are alone valid, since you are human, then you wouldn't exist. Prior to your existence you could not think, and you could not have had a notion of yourself, so then you're still nothing, or to think that you could have designed yourself bringing yourself into being prior to existing is absurd. Even now your thoughts cannot be the exclusive possessors of validity for you cannot make things to exist nor create things with your thoughts. God alone creates, humans rearrange pre existing material or pre existing ideas.

[@katerinamakedoniaGreece]

Aristoteles was Macedonian Greek! Macedonians were Greeks. Slavs aren't Macedonians. So the slavs and mix of Bulgarians Albanians in North of Macedonia aren't Greeks Macedonians! That's truth! But fake,lies and untruths can't be proved when wrong is telling everyday and makes a myth! Politicians can make a false theory be "truthful " when they have the power of propaganda! Greeks must prove now that they're still exists and they aren't a myth. From Macedonia in Greece, regards
