A Treatise on the Soul and its Origin.: Chapter 31

Chapter 31 [XX.]—Modes of Knowledge in the Soul Distinguished.

Forasmuch, then, as there is one function in the soul, by which we perceive real bodies, which we do by the five bodily senses; another, which enables us to discern apart from these non-corporeal likenesses of bodies (and by this we can have a view of ourselves also, as not otherwise than like to bodies); and a third, by which we gain a still surer and stronger insight into objects fitted for its faculty, which are neither corporeal nor are like bodily substances,—such as faith, hope, charity,—things which have neither complexion, nor passion, nor any such thing: on which of these functions ought we to dwell more intently, and to some degree more familiarly, and where be renewed in the knowledge of God after the image of Him who created us? Is it not on and in that which I have now put in the third place? And here we shall certainly experience neither sexual difference nor the semblance thereof.
