Now let us read Blessed Raymond's description of the evacuation process in Ars Brevis, followed by Fr. A further link at the bottom of the page goes to texts that deal with angelic communication, angels moving physical things, and angelic enjoyment. In the third figure , the intellect evacuates cameras, because it draws from them as much as it can, by receiving from each camera the things signified by its letters, so as to apply these meanings to the question at hand. And thus it applies itself to investigation and discovery. And we will give an example of this in one camera, and whatever is said about it, also applies to the other cameras.
Greatness is good, greatness is different, greatness is concordant.
Difference is good, difference is great, difference is concordant. Concordance is good, concordance is great, concordance is different. As these twelve statements are made, by switching the roles of subject and predicate back and forth, the camera is evacuated of these statements. Next, the intellect evacuates it with twelve media, and these are called media, because they stand between the subject and the predicate, with which they are in general or in specific concordance. And it does likewise with the other principles and combinations in the camera.
