Deductive Test - Argument Flow Chart 10/8/08

In this section you will find some notes on a discussion in whichTom Louvier and I are currentlyengaged. Both of us are disatisfied with the manner in which the discusion surrounding arguments is currently presented in texts. The problem we aree attempting to address focusses on the ridgid dichotomy usually applied to inductive deductive arguments. This traditional distinction has always been maintained . At times, entire chapters are devoted to either induction or deduction. On the one hand entire books have been devoted to the study of informal fallacy while on the other hand classic texts dealing only with formal relationships within arguments have been purportedly submitted as the correct analysis. One of the primarary concerns that is to be addressed when constructing an argument is that a person never wants to construct an argument using the very best informationand and end up with a false conclusion. If an argument is so constructed that it would be impossible to arrive at a false conclusion if the premises are true this argument would be classified as deductively valid. There are many different formulations of this rule for determining deductive validity.

If in the drawing to the right we s'pose that the premises are T
the the level of certainty for the conclusion equals 100%. Pc=100%

we stop the analysis
