Abstract

The paper takes its departure from Ingarden's distinctions between four different main modes of being: absolute, extratemporal, real, and purely intentional. It introduces a distinction between two kinds of ideal entities: impurely ideal and purely ideal. Of the former kind are universals, and of the latter numbers; Ingarden regards both as existing in the extratemporal mode. It is then discussed whether Ingarden, and many others, has fallen prey to a mode illusion; and that, in fact, the impurely ideal entities exist in the real mode and the purely ideal in the purely intentional mode of being. The answers are weakly affirmative. On these presuppositions a concept of “mixed intentional object” is introduced. It seems to be of importance for how to understand numerical scales and the development of science.
