Received: 14/01/15 • Accepted:17/01/15 The aim of this article is to explain the relationship between lifeworld (Lebenswelt) and the concepts of originality (Originalitat) and primordiality (Primordialitat) in the philosophy of Edmund Husserl, based on the idea that, in order to gain access to Ontology of the world in general, it is necessary to do the transcendental phenomenological analysis. This is why we need to explain how the Transcendental Philosophy relates to the Transcendental Aesthetics and, phenomenologically, therefore, how it places all what is outside of theory and reflection (i.e., the natural world) as a precondition for all classifications.
