Martin Heidegger said this quote
“ Being, as the basic theme of philosophy, is no class or genus of entities; yet it pertains to every entity. Its 'universality' is to be sought higher up. Being and the structure of Being lie beyond every entity and every possible character which an entity may possess. *Being is a transcendens pure and simple*. And the transcendence of Dasein's Being is distinctive in that it implies the possibility and the necessity of the most radical *individuation*. Every disclosure of Being as the *transcendens* is *transcendental* knowledge. *Phenomenological truth (the disclosedness of Being) is veritas transcendentalis*.Ontology and phenomenology are not two distinct philosophical disciplines among others. These terms characterize philosophy itself with regard to its object and its way of treating that object. Philosophy is universal phenomenological ontology, and takes its departure from the hermeneutic of Dasein, which, as an analytic of *existence*, has made fast the guide-line for all philosophical inquiry at the point where it *arises* and to which it *returns*.―from_Being and Time_.
