5.5 · Intellect turns toward itself
I.48.5.5 · Wachsmuth pp. 313-314
With intellect, however, apprehension does not occur in this way, but through its turning into itself and contemplating itself. For if it ceased to behold its own activities and to be the eye of its own activities ⟨producing⟩ the sight, it would think nothing. As there were perception and the perceptible, then, so there are intellect and the intelligible.1230
5.6 · Intellect and imagination distinguished
I.48.5.6 · Wachsmuth pp. 314
Perception contemplates by extending outward and finding the perceptible situated ⟨in⟩ matter; intellect does so by gathering into itself, without extending outward at all. Some also took it in this way, ⟨not even⟩ making a distinction of name between the subsistence of intellect and ⟨that⟩ of imagination.1231 For they had judged imagination in a rational living creature to be thinking. But [if], for those who made everything depend on matter and corporeal nature, it was consistent to make intellect depend on these too.1232
5.7 · Intelligibles have no external place
I.48.5.7 · Wachsmuth pp. 314
But our ⟨intellect⟩ contemplates incorporeal and different substances: where, then, will it find them situated when it apprehends them? Since they are outside matter, these things would be nowhere. It is clear, ⟨then⟩, that as intellectual things they will be gathered together by thinking. [And] accordingly, if intellectual things ⟨enter⟩ intellect, [and the intelligible,] it will also contemplate itself when it thinks the intelligibles; and in entering itself it thinks because it enters them.1233
5.8 · The conclusion: unity precedes multiplicity
I.48.5.8 · Wachsmuth pp. 314
If the intelligibles [too] are many (for intellect thinks many things, and not one), intellect itself too must necessarily be many [also]. But the One is prior to the many; hence the One must be prior to intellect.1234
6.1 · Archytas: the measures of things
I.48.6.1 · Wachsmuth pp. 315
From Archytas, from On Intellect and Perception.
Perception occurs in body, intellect in soul. The former is a principle for perceptible things, the latter for intelligibles. For number is the measure of multitude, a foot of length, a balance of downward inclination and weight, and a rule, a plumb line, and a right angle of uprightness and straightness. So too perception is the principle and measure of perceptibles [measure], and intellect of intelligibles.1235
6.2 · The purposes of perception and intellect
I.48.6.2 · Wachsmuth pp. 315
Intellect is a principle for things intelligible ⟨and⟩ primary by nature; perception for things ⟨secondary by nature and those in relation to⟩ us. For the former is a principle for soul, the latter for body. Intellect judges the most worthy things, perception the most useful. Perception is constituted for the sake of the body and the service directed to it; intellect ⟨for the sake of soul⟩ and the resourceful understanding directed to it.1236
6.3 · Knowledge, opinion, and their objects
I.48.6.3 · Wachsmuth pp. 315-316
Intellect is the principle of knowledge, and perception of opinion; for the latter has its activity from perceptibles, the former from intelligibles. Among things, the perceptibles share in motion and change, while intelligibles share in rest and eternity.1237
6.4 · Variable seeing and unvarying understanding
I.48.6.4 · Wachsmuth pp. 316
Perception and intellect stand in corresponding relations: perception to the perceptible, which moves and changes and never remains still in the same condition. Hence it is possible to see ⟨the perceptible⟩ more or less, better or worse. Intellect stands in relation to the intelligible, which is unmoving in its very being; hence one cannot understand the intelligible more or less, better or worse.1238
6.5 · Paradigm and image
I.48.6.5 · Wachsmuth pp. 316
⟨And⟩ just as intellect beholds what is primary and the paradigm, so perception beholds the image and what is secondary. For intellect beholds heaven without qualification ⟨or art⟩, while perception simply beholds the sun’s sphere or those of craftsmen.1239
6.6 · The indivisibility of intellect and form
I.48.6.6 · Wachsmuth pp. 316
Further, intellect is without parts and indivisible, like a unit and a point, and likewise the intelligible. For form is neither a body’s limit nor its boundary, but solely an impress of what is, insofar as it is. Perception, however, has parts and is divisible.1240
6.7 · Four classes of objects
I.48.6.7 · Wachsmuth pp. 316-317
For among things that are, some are perceptible, some objects of opinion, some objects of knowledge, and some intelligible. Bodies, which have a certain resistance, are perceptible. Objects of opinion are things that participate in forms as images do, as a particular human being participates in human being, and a ⟨particular⟩ triangle in triangle. Objects of knowledge are the properties that necessarily belong to forms, as in geometry those that belong to figures. Intelligibles are the forms themselves and the principles of the objects of knowledge, such as circle itself, triangle, and sphere.1241
6.8 · Four kinds of cognition
I.48.6.8 · Wachsmuth pp. 317
In our own souls too there are four kinds of cognition: intellect, knowledge, opinion, and perception. Two are starting points of reason, namely intellect and perception; the other two are its completions, namely knowledge and opinion. Like always has the capacity to know like. It is clear, ⟨then⟩, that intellect in us knows intelligibles, knowledge knows objects of knowledge, ⟨opinion knows objects of opinion,⟩ and perception knows perceptibles.1242
