ABSTRACT
W hen evaluating argumentation, the argumentation mustfirst be checked for logical and pragmatic inconsistencies.Then each individual single argument must be assessed to determine whether it is based on valid reasoning. To do this, any unexpressed elements must be made explicit. Because the unexpressed premise is usually also a clue to what type of argumentation is being used, it indicates which argument scheme links the explicit premise to the standpoint. This is helpful when evaluating the soundness of each single argument: then it must be determined whether the constitutive argumentative statements are acceptable and whether all the critical questions can be answered that are relevant for the argument scheme that is used.
