Repairing Arguments

One major problem with any argument is that the sentence does not have the proper premises to support it's conclusion. With the Principle of Rational Discussion, we can find out how to evaluate and interpret any arguments. The three rules of the Principle of Rational Discussion are "Know about the subject under discussion, is it able and willing to reason well, and if it's not lying." (Epstein. pg 60) An example of an argument that does not have a premises that supports the conclusion is, "My sister does not have a job, so because of that she should not buy a car." This argument is weak because it needs more details to support the conclusion. To make the argument better we should add "Buying any type of car requires a job to pay for the monthly payments." For anyone to buy a car requires that person to have money, if the person does not have a job then the idea of buying a car would only be a dream if the person had no source of income. By adding in that part to the original sentence the argument becomes stronger because it is now clear why someone with no job should not buy a car.
