Our present subject concerns the soul, and the point is to prevent the insidious ascription of a superiority to the intellect or understanding. Now, although the objects which are touched by the intellect are of a higher nature, since they are spiritual, than those which are embraced by the senses, since these are corporeal, it will still be only a superiority in the objects—as of lofty ones contrasted with humble—not in the faculties of the intellect against the senses. For how can the intellect be superior to the senses, when it is these which educate it for the discovery of various truths?
…Two conclusions therefore follow from what we have said: (1) That the intellect is not to be preferred above the senses, on the (supposed) ground that the agent through which a thing exists is inferior to the thing itself; and (2) that the intellect must not be separated from the senses, since the instrument by which a thing’s existence is sustained is associated with the thing itself.
Tertullian
