The first thing to keep in mind is Heidegger’s insistence that being (Sein) is not a being (Seindes). If being is not itself a being, but rather that against which beings are revealed in their being, then being cannot be a being as there would be no possibility of encountering beings in the first place. Heidegger holds that in order for things to be intelligible they must be encountered against a horizon (or background) through which their qualities may be discovered as meaningful properties. Magda King’s own example is of Aristotle’s understanding of being as substantiality. When the being of beings is understand as substantiality, beings themselves may demonstrate their being (and therefore be understood) in terms of what is “brought forwards” by our a priori understanding of substantiality. Which means that the being (Seindes) encountered will be in a position to display its being as substance, where its properties of extension, mass, solidity, etc, can make sense (i.e. have meaning).Plus, where is E-Prime in all this?
