ABSTRACT: This article brings to the fore the problem of becoming a human being and consequently seeks an explanation for the mind-body ontological duality. The analysis considers the prism of the Plotinian vision. The author interprets the work Enneade extracting the argumentative scheme of Plotinus through which the dual nature of the human being seeks to reconcile the two ontologies. In Enneade, Plotinus expounds on the ways in which the human being tends to become the being, to his rational purpose, without denying the beauty of the sensitive world. The conclusion of the study identifies in Plotinus’ work the mystical ecstasy as the common element of the components of the human being, this being also the path to becoming. KEY WORDS: Plotinus, becoming being, mystical ecstasy
