ABSTRACT
The Principle of Reason spells out the relation between Being and entities in a particularly interesting way because such a relation seems to take different nuances in light of the different understandings of Being. Entities and their Being have been the cardinal points around which Martin Heidegger articulates his whole philosophical inquiry. It has been the source of many different understandings of Heidegger’s Being and, in this vast array of interpretations, two of them appear to be the most significant. The first one is the “metaphysical interpretation”, voices the ontological aspects which are present in the first clause of Heidegger’s quotation. The second one is the “intelligibility interpretation”, voices the epistemological aspects which are present in the second clause of Heidegger’s quotation. Heidegger also thinks that assertions are used to attribute specific predicates to specific subjects. Using Heidegger’s allusive jargon, one can say that being an entity “belongs” to self-identity; self-identity “finds its home” in the realm of entities.
