The text gives three more formulations:
الحاضر عند المدرك
That which is present to the perceiver.
قبول النفس لتلك الصورة
The soul's reception of that form.
الإضافة الحاصلة بين العالم والمعلوم
The relation obtaining between knower and known.
These respectively focus on the object as present, mental reception, and a relation between knower and known. They must be understood as different proposed analyses, not collapsed into a single sentence.
