Burley, De puritate, p. 59:
Ad secundum dico, quod ens potest accipi tripliciter. Uno modo ut est maxime transcendens et commune omni intelligibili. Et sic est adaequatum obiectum intellectus.
To the second [objection] I say that being can be understood in three ways. In one way as it is maximally transcendental et common to every intelligible.
To be sure, this is just a hint. But one of the supertranscendentals is the intelligible, which is common to being of reason and real being.
I intend to post on Scotus and the supertranscendentals in a few days.
