VII. The sciences, however, of sensibles, which are in the rational soul, if it is proper to say that there are sciences of these, since the appellation adapted to them is that of opinion, in consequence of being posterior to sensible things, are the images of them. But the sciences of intelligibles, which are truly sciences, and which descend from intellect into the rational soul, understand indeed nothing sensible; but so far as they are sciences, are each of the things which are the objects of their perception; and possess internally the intelligible and intelligence. This, however, is because intellect is inward, which is primary natures themselves, is eternally present with itself, and exists in energy. It likewise does not extend itself to the objects of its perception as if it did not possess them, or as if it acquired them externally, or obtained them by a discursive process, as if they were not already present with it (for these are the passions of soul); but it stands firmly in itself, being at once all things, and does not energize intellectually in order that it may give subsistence to every thing. For it does not, when it intellectually perceives God, become God, nor when it understands motion does it become motion. Hence, if the assertion that forms are intellections signifies, that when intellect understands this particular form it then becomes that form, it is not true. For it is necessary that the object of intellection should be prior to this intellectual perception. Or how would intelligence arrive at the perception of it? For it cannot be fortuitously, nor does intelligence extend itself towards the intelligible in vain.
