Recent Advances in Metaphysics: Ontological Categories and Categorial Schemes

From a traditional ontological perspective, and with the declared intention to move away from contemporary relativism, this paper aims to establish some basic principles to maintain the position of Metaphysics as the systematic study of reality as a whole, and Ontology as the science of being, based on a theory of categories. These categories are differentiated by the distinctive features of existence and identity of their respective members, taking as «fundamental ontological categories» those where its members have conditions for these characteristics of existence and identity that are not exhaustively specifiable, in terms of ontological dependence, between those members and members of other ontological categories. This paper then makes a revision of the different theories of ontological categories, and their respective interpretations of how many and which categories should be recognized
