The perception of the natures which compose the universe has been justified in the preceding chapters.
These nature are not being, but have being. Thus they receive being, because all that is not being (but nevertheless has being) must receive it from whoever is being.
Therefore, whoever is being must give being to the natures which compose the universe and are perceived by us.
But that which is being and gives being to creatures is cause, that is, God.
[Antonio Rosmini, Certainty, Cleary & Watson, trs., Rosmini House (Durham: 1991), p. 119 (section 1212).]
Very similar, of course, to the argument in St. Thomas's De ente et essentia (and Rosmini goes on immediately to give an adapted version of this that clearly is related to the First Way).
