      I’m currently enrolled in an Intro To Logic course and it is, by far, the most pointless class I’ve ever taken. Teaches you absolutely nothing about logic and was a complete waste of time - and that’s coming from somebody who would like to agree with the concept of “learning never being pointless”. Definitely the most illogical shit I’ve ever come across. Fuck me

    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.

  • @georgemissailidis3160
    @georgemissailidis3160 Рік тому +1

    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!

      Correct about the error in Dave's video at 6:05. I was about to post the same thing but figured I'd check the comments first to be sure it wasn't already here. Dave indeed did mean to type "All mortals are human", but it's anybody's guess as to whether he'll correct that error. Last time I checked, he had not corrected his sports error from last month about athletes being on a winning streak from factors other than randomness, despite multiple commenters telling him.

    • @davidh.4944
      @davidh.4944 9 місяців тому

      I believe his error at 6:05 is in getting the entire syllogism backward, rather than just P2. It really should be this:
      P1: All UA-camrs are human.
      P2: All humans are mortal.
      C: All UA-camrs are mortal.
      Saying "All mortals are human" would work make the original syllogism valid, but it would be obviously unsound.

    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?

    • @9fmradisapratama
      @9fmradisapratama Рік тому

      I think it's the source operator the premise refers to. Some generic AI with fake pre dialogue to sound scary and self aware are pre programmed to say such things. Also, they're man made objects with the operator being human.
      They can be easily immortalized through UA-cam videos and clips so they'll never age as well but what I think being 'mortal' here is just an aging flesh. Not avoiding death. Not even the current AI can escape death such as their programming can just be purged or aging hardware will make them to not operate. The fatal is when it gets to the memory hardware they can't backup.
      But that might be a big gibberish wrong statement. I think I might confuse the operator and things in particular. Let the video and Professor Dave explain.
