Heidegger on phenomenology.
The a priori character of being and of all the structures of being accordingly calls for a specific kind of approach and way of apprehending being - a priori cognition.
The basic components of a priori cognition constitute what we call phenomenology. Phenomenology is the name for the method of ontology, that is, of scientific philosophy. Rightly conceived, phenomenology is the concept of a method. It is therefore precluded from the start that phenomenology should pronounce any theses about being which have specific content, thus adopting a so-called standpoint.
