The aim of this paper is to propose a metaphysical approach to the philosophical method as a process of thought and, in that way, to affirm that the philosophical research get a foundation in the relation notion as a metaphysical absolute. This thesis that I hold, shows, that it is a fundamental ontological expression, and that the notion of a portion is the concept whit a minimum of sense for all ontology of multiplicity and gnoseological criteria. If I assume those as premises, I deduce from them the notion of proportion (analogy). This makes it possible to think in a congruent link between an ontological word calls a and a gnoseological criterion calls b.
