Abstract
The purpose of my paper, which has been inspired by Eugenia Ginsberg-Blaustein’s analysis of the concepts of existential dependence and independence, is to shed further light on the concept of existential dependence and connected concepts in their applications to the mental sphere, namely to the analysis of mental content. To realize this purpose, I shall extend Ginsberg-Blaustein’s analysis to Roman Ingarden’s phenomenological approach with his characterization of the concepts of heteronomous existence, existential dependence and other associated concepts.
