The Existentiell (n.) is the individual self of man in so far as it is interested in itself as this particular entity. It is the selfhood of man in so far as it is related not to the individual self but to being and the relationship to being the selfhood of man in so far as it is related not to the individual self but to being and the relationship to being.
Existentiell (n.) is a term pertaining to some individual Dasein's own existence, for example “Should I apply to medical school?”
Existentiell (n.) is an understanding about ourselves and thus a kind of understanding we all have, gained simply by living, though it is always partial, and defective.
Existentiell (n.) is a form of understanding not made up of explicit theories, but simply a competence to exist and deal with various kinds of entities.
Existentiell (n.) is where even ontology has its roots: the analysis of existence's structures grows out of one's own way of existing, so the philosopher questions Being only from inside a life already taking a stand.
