Il De quiditate et esse attribuito ad Alberto Magno. Una nota sulle origini della distinzione tra res a reor reris e res a ratitudine

Among the various questions on different subjects attributed to Albert the Great, and presumably disputed in Paris around the middle of the 13th century, we find one – handed down mainly under the title De quiditate et esse – dedicated to the presentation of some fundamental notions of metaphysics. This particular question deserves attention insofar as it represents a significant moment in the geneaology of the distinction between the notions of res a ratitudine and res a reor reris. A final remark concerns the possible connection between Albert the Great and Henry of Ghent with respect to the transcendental primacy of res and the attempt not to reduce the consideration of metaphysics to actual being alone
