Aristotle. Imagination is a certain affection and movement of perception in activity. It takes its name from one of the senses, sight; ⟨for⟩ appearing derives its designation from light.2054
1.2 · Extension beyond sight
I.58.1.2 · Wachsmuth pp. 497
This belongs properly to sight, but extends ⟨to⟩ all the senses and the movements of thought; for these too are called imaginations by the same name.2055
1.3 · Intellect and perception as criteria
I.58.1.3 · Wachsmuth pp. 497
The criteria for knowledge of these things are intellect and perception: intellect for intelligible things, perception for perceptible things. For perception could not judge the universal, nor intellect the particular. Everything is constituted from these and through these.2056
