 Lastly, Heytesbury introduces the so-called “ampliatio”, which consists in extending the range of a term to non-actual entities, such as entities in the past, future, or mere possibilia. Thus, for instance, the proper paraphrase of the sentence “a white thing can be black” is “something that now is white or can be white can be black” ([SCD] 1494: fol. 2va [1988a:  418]).[19]  The complementary property is called “restrictio” ([Soph] soph. 4 [1494: fol. 89vb]).
