    Comment-3: Example (8:04). Algebraic calculation:
    TERMS: x - men, y - mortal, z - Socrates.
    1. All men are mortal (xy)
    2. Socrates are men (zx)
    - - - Calculation: ((xy)*(zx))/X = (xyz)/X = yz = zy
    3. Socrates are mortal (zy)
    You are right! Score T:F = 1:2

    I think there's a mistake at 21:00. Shouldn't there be only one x in section 5, making the conclusion valid?

    • @timffoster
      @timffoster 4 ปีที่แล้ว

      If I'm understanding it olcirrectoy, no, it's not valid. See his following explanation where he uses the same form of argument to talk about politicians and clowns.

    Comment-6: Example (19:59). Algebraic calculation:
    TERMS: x - animals, y - mammals, z - tigers.
    1. All mammals are animals (yx)
    2. All tigers are mammals (zy)
    - - - Calculation: ((yx)*(zy))/Y = (xyz)/Y = xz = zx - - -
    Yours: 3. Some tigers are animals - ERROR CONCLUSION [as zx+zx’ - why??]
    RIGHT: 3. THERE IS tigers SO AZ animals [meaning «mammals»] (zx)
    You are wrong! Score T:F = 1:5

    Comment-4: Example (10:51). Algebraic calculation:
    TERMS: x - Mid, y - Maj, z - Min
    1. No Mid are Maj (x’y)
    2. Some Min are Mid (zx+zx’)
    - - - Calculation: ((x’y)*(zx+zx’))/X = (x’yz)/)/X = yz = zy
    3. Yours: Some Min are not Maj - ERROR CONCLUSION
    3. RIGHT: THERE IS Min SO AZ not Maj (zy)
    [Formula «Some Min are not Maj» (instead of (zy)) is (zy+zy’)]
    You are also not right! You are wrong! Score T:F = 1:3

  • @Syllogist
    @Syllogist 2 ปีที่แล้ว

    SO FAR ABSOLUTLY ANY SYLLOGISM CAN CALCULATE AS ALGEBRAIC FORM… I saw some mistakes into this video-clip…
    Comment-1: Example (5:17). Algebraic calculation:
    TERMS: x - fireman, y - brave , z - stone.
    1. All fireman are brave (things) (xy)
    2. No brave things is a (thing made of) stone (y’z)
    - - - Calculation: ((xy)*(y’z))/Y = (xy*y’z)/Y = 0/Y = 0
    3. YOUR ERROR: No (thing made of) stone is a fireman
    3. VALID,RIGHT: Term «stone» NOT CONNECTED WITH term «fireman» (0)
    [because volumes of these terms are not crossing]
    You are wrong! Score «True:False (T:F)» 0:1

  • @Syllogist
    @Syllogist 2 ปีที่แล้ว

    Comment-2: Example (6:20). Algebraic calculation:
    TERMS: x - penguins, y - Olympic athletes, z - cold-blooded.
    1. No penguins are Olympic athletes (x’y)
    2. No Olympic athletes are cold-blooded (y’z)
    - - - Calculation: ((x’y)*(y’z))/Y = (x’y*y’z)/Y = 0/Y = 0
    3. YOUR ERROR: No penguins are cold-blooded
    3. VALID,RIGHT: Term «penguins» NOT CONNECTED WITH term «cold-blooded» (0) [Volumes of these terms are not crossing]
    You are wrong! Score T:F = 0:2

  • @Syllogist

    Comment-5: Example (14:45). Algebraic calculation:
    TERMS: x - penguins, y - Olympic athletes, z - cold-blooded.
    1. No Olympic athletes are cold-blooded (y’z)
    2. Some penguins are Olympic athletes (xy’+xy)
    - - - Calculation: ((y’z)*(xy+xy’))/Y = (xy’z)/Y = xz = zx
    3. YOUR ERROR: Some penguins are not cold-blooded [zx+zx’ - why???]
    3. RIGHT: THERE IS penguins SO AZ cold-blooded (xz) [meaning «Olympic athletes». Because volumes of syllogism terms place only into 3 terms!]
    You are wrong! Score T:F = 1:4

    Yours: 3. Some tigers are mammals - ERROR CONCLUSION [as zy+zy’ - why?]
    RIGHT: 3. THERE IS tigers SO AZ mammals [meaning that «animals»] (zy)
    You are wrong! COMMON SCORE T:F = 1:6
    IN ALL: ONE SYLLOGISMS WAS RIGHT and SIX SYLLOGISMS - IS LIE!
    Sorry, but this is only typical logic algebra :-)
