ABSTRACT
With non-conclusive verbs there can be no doubt: the passive is in the same tense as the auxiliary: he is admired is a present tense, because is is present and admired is no tense in particular; was admired is a preterit. Similarly with it is (was, has been) generally believed, etc. In all such cases the participle is a predicative of being (13.1; 5), and we may therefore speak of a passive of being.
