Οὐσία means “being-there,” and it does not have an indifferent sense of being, as, ultimately, there is no such thing. Οὐσία is the abbreviation for παρουσία, “being-present.” Usually the opposite is ἀπουσία, “absence,” not simply nothing but something there, although there as a lack. Squinting is a matter of seeing in the mode of ἀπουσία. Ἀπουσία is the ontological basis for the basic category of στέρησις. We want to try to bring the aforementioned characters of the there to a basic orientation. [Heidegger  , GA18:33-34]
