But the light of the active intellect abstracts intelligible species from phantasms.

But habits and intelligible species cause things to be known by the soul.

Therefore much more is the intellectual soul created by God under intelligible species.

For the intellect is made actual by the intelligible species by which it is informed.

Therefore the intelligible species, by which the soul understands, are caused by some separate forms.

Therefore, when an intellectual substance is seen, the intelligible species within it is also seen.

But intelligible species are not opposed to each other.

Therefore the intelligible species suffices for the intellect to understand actually, without turning to the phantasms.

Therefore the angel inclines towards the good through his own nature, or through an intelligible species.

But nothing of what is understood is in the intellect actually understanding, save the abstracted intelligible species.

For the habit which is in the intellect is the intelligible species, by means of which the intellect actually understands.

And sometimes the intelligible species is in a middle state, between potentiality and act: and then we have habitual knowledge.
