Exambles For Deductive & Inductive

In Deductive we infer particular from General Truths; While in Induction we infer General from Particular.


Example for Deductive Argument:


       1   All men are martal
            Socrates is a man
            Therefore Socrates is mortal.
                                            (valid)
                                       * * * * * * * * * * * * * *
       2  Puthukkudy is a violent place
           Johnny is from puthukkudy
          Therefore Johnny is violent.
                                             (invalid)
Here a particular conclusion inferred from premisses the first of which is a general proposition.
                                      * * * * * * * * * * * * * *
Example for Inductive Argument:


       1 Socrates is a man and is mortal
          Plato is a man and is mortal
         Aristotle is a man and is mortal
        Therefore probably all men are mortal
                                                (valid)
    2  Mr.D.P.Mony is a Puthukkudy man and famous
       Mr.Rajan is a Puthukkudy man and famous
        Mr.Johnny is a Puthukkudy man and famous
       Therefore probably all Puthukkudy men are famous.
                                                 (invalid)
Here a general conclusion is inferred from premisses all of which are particular proposition.


                                             Q because P
                                             -------------
If we are interested in establishing the truth of Q, and P is offered as evidence for it, then "Q because P" formulates agreement. However, if we regard the truth of Q as being unprobablematic, as being at least as well established as the truth of P but are interested in explaining why Q is the case, then "Q because P"is not an argument but an explanation.The two examples discussed are fairly easy to distinguish, the first being an explanation and the second an argument.But not all examples are so easily classified. In each case the context may help to make clear the intention of the writer or speaker. If his purpose to establish the truth he
formulates an argument. if his purpose is to explain , then he formulates an explanation.
