The argument from evaluation is a first-order predicate argument that supports a policy with a value (1 pre PV).
ANALYSIS OF AN EXAMPLE
You have to do paragliding, because it is a great experience
The arguer states in the conclusion that a certain activity should be carried out and supports this claim by stating that the activity is a great experience. Since the argument fits the form a is X, because a is Y, it can be identified as a first-order predicate argument. In this specific case, a is instantiated by ‘paragliding’, Y is instantiated by ‘has to be done by you’, and X is instantiated by ‘is a great experience’.
Paragliding (a) has to be done by you (X), because paragliding (a) is a great experience (Y)
First-order predicate arguments are further differentiated by identifying the types of statement in the conclusion and the premise. In this case, the former is a statement of policy and the latter a statement of value, which means that we are dealing with a first-order predicate argument supporting a policy with a value (1 pre PV).
The trivial name of first-order predicate arguments is derived from the characterization of the relationship between the predicates X and Y. In this example, the evaluation of the activity, that it is a great experience (Y), functions as a reason for that it has to be done by you (X). We can therefore call such an argument an ‘argument from evaluation’.
