Def Empirical Adequacy/Fraassen: there is a model, so that all phenomena can be identified with movements in the model (also historical, not perceived ones).

I 84f
Empirical Adequacy/Fraassen: is (unlike truth) a global property of theories - i.e. there is no general pattern of statements so that if all statements (propositions) of the theory each have this characteristic in themselves, then the theory is empirically adequate.
Since theories are families of models each of which has a particular family of substructures that correspond to possible phenomena (empirical substructures).
Problem: because the empirical meaning cannot be syntactically isolated, empirical adequacy must be defined directly without empirical detours.
Empirical adequacy of a single statement can only be determined in terms of a theory. - Problem: unlike truth, one theory may be empirically adequate and another may not.
Then a conjunction of theories must be treated differently than in the case of truth.
>Truth, >Theories.
