ontology 

In philosophy, the theory of the existence of things—at its most basic, or fundamental, it seeks to answer the question why there is something rather than nothing. It does not examine the existence of particular things; its focus is the more general level of the possibility and actuality of anything existing at all. In the 20th century, the most influential account of ontology is given by Martin Heidegger, in his extensive writings on the subject.
