Ontology and Metaphysics: A Study on the Kantian Substantiation of Ontology and the Sense of Metaphysics in Relation to Itself

The aim of the following paper is to show that the Kantian substantiation of the ontology aims for the liberation of the possibility of what in Kantian words is known as "metaphysics per se". In order to do so, this paper mainly focus on the exposition of the substantiation of the ontology found in the Trascendental Analytics of the Critique of Pure Reason (KrV), offering a vision of the place that ontology, as general metaphysics, occupies in the system regarding the particular metaphysics, as well as the relationship between ontology and metaphysics. The ultimate aim is to unravel the meaning of the prefix "meta-" in this very last word, showing that in order to interpret the word in a correct way it is necessary to distinguish between the different sense of being, namely sensible being (being as phenomenon) and supersensible being (being as noumenon), as a double semantic regime for the grammar of Nature and Freedom.
