Form and Substitution Instance

  • An argument form is the result of replacing all simple sentences and terms in an argument with capital letters
  • A substitution instance of an argument form is the result of replacing all capital letters in an argument form with complete sentences or terms
  • A counterexample to an argument form is a substitution instance that invalidates the corresponding argument from - it has true premises and false conclusion
  • Ex. 1 All geese are migratory waterfowl
  •                           All migratory waterfowl are birds that fly south for the winter

                              Therefore, all geese are birds that fly south for winter.

                    1.) All G’s are W.

                    2.) All W’s are B.

                    3.) All G’s are B’s.

  • Ex. 2
  •      All romantic novels are literary pieces True                        Replace withIf you want to learn more check out What are the variables affecting viscosity?
    We also discuss several other topics like What is the evolutionary history of different organism?

    (All A are B)                                                         A = Cat

         All works of fiction literary pieces True                                 B = Mammals

            (All C’s are B)                                                         C = Dogs

         Therefore all romantic novels are works of fiction false

            (All A’s are C)

  • Ex. 3
  •      Since some employees are not social climbers and all vice presidents are employees, we may conclude that some vice presidents are not social climbersIf you want to learn more check out clemson syllabus

    Replace with : E’s = animals

                    C’s = mammals

                    V’s = dogs

    1. Some E’s are not C’s
    2. All V’s are E’s
    3. Some V’s are not C’s

                                    

    1. Some animals are not mammals true
    2. All dogs are animals true
    3. Some dogs are not mammals false

  • Ex. 4
  • If the government imposes import restrictions, the price of automobiles will rise. Therefore, since the government will not impose import restrictions, it follows that the price of automobiles will not rise.Don't forget about the age old question of 9q ex) when was green revolution and what were its something?

    G = Ab.Lincoln committed suicide

    P = Ab.Lincoln is dead

    1. If G the P
    2. Not G
    3. Not P

    1. If Ab Lincoln committed suicide then he’s deadtrue
    2. If Ab Lincoln did not commit suicidetrue
    3. If Ab Lincoln is alive false

    Don't forget about the age old question of What does the term accrual basis accounting mean?

    Conduct counterexample

            

  • Ex. 5
  • Some politicians are people who will step at nothing to win an election and no people will stop at nothing to win an election and good statesmen. Hence no politicians are true statesmen.

    1. Some A’s are B’s
    2. No B’s are C’s
    3. No A’s are C’s

    - A sentence is compound if it contains another complete sentence as a component

    - A sentence is simple if and only if it is not compound

    - One sentence is a component of another sentence, the result is still a grammatical sentence

    - One sentence logicallyWe also discuss several other topics like What does title tell me?

    * All negations are compound

    Homework:

    Moby Dick

  • Valid, unsound
  • All premise is false        
  • D.C and Hexagon

  • Invalid, unsound, false premise and conclusion
  • Our project is the evaluation of a deductive arguments
  • Counterexample = substitution
  •                                              A                  B    

                                    1. Some dogs are vicious animals (T)

                            B                               C        

    invalid                2. No vicious animals are good pets (T)

                                                    A             C

                                        Hence no dogs are good pets (F)
