Summary. The aim of this article is to reflect upon the relations which John Duns Scotus, in the famous third distinction of the first book of the Ordinatio, institutes between the univocal concept of being as being and the natural intellect of the viator who intelliges the being. In particular, one asks how, in the light of the concept of being as being, an adequate intellect can intellige each of its intelligibles according to its own perfect essential definition.
