 […] God has provided our mind with some intellectual light, by means of which it would abstract the species of objects from the sensibles, by purifying them and extracting their quiddities, which are the per se objects of the intellect. […] But this light is not sufficient, for it is defective, and is mixed with obscurity, unless it is joined and connected to the eternal light, which is the perfect and sufficient reason for cognition, and the intellect attains and somehow touches it by its upper part.
