If we call those aspects of experience which has as an essential part of their constitution or their condition of possibility an awareness of awareness (such as sexual desire, shame, anxiety, insomnia etc) 'existentiell' then is there any ground for separating them from ontology? Aren't they just applied or performative ontology? Neither could exist without the other. And could any of this be separated from what we ean when we speak of consciousness? (Again, this has nothing to do with so-called 'qualia'.)
