Duns Scotus, Reportatio II d. 13 q. un (ed. Wadding-Vives vol. 23 p.44):
"...tamen hoc nomen intentio aequivocum uno modo dicitur actus voluntatis; secundo, ratio formalis in re, sicut intentio rei, a qua accipitur genus, differt ab intentione, a qua accipitur differentia; terio modo dicitur conceptus; quarto, ratio tendendi in obiectum, sicut similitudo dicitur ratio tendendi in illud cuius est..."
Nevertheless this term 'intention' is equivocal. In one way it is called the act of the will. In the second, the formal ratio in a thing, just as an intention of the thing, from which the genus is taken, differs by intention, from which is taken the difference. In the third way it is called a concept. In the fourth, the means of tending into an object, as a likeness is called a means of tending into that of which it is a likeness.
