A cardinal principle of Objectivist metaphysics is the primacy of existence which asserts that there is one objective world, which exists independently of consciousness. This fact is irreducible and does not have to be proved because existence is the fundamental self-evident truth that lies at the foundation of all knowledge.

Objectivism holds that each of these axioms is implicit in any act of knowledge, thus, the primacy of existence is a fact contained within the truths of these philosophical axioms.
