XIII.  This will be made clear to you as follows:—Are not Spirit, and Fire, and Light, Love, and Wisdom, and Righteousness, and Mind and Reason, and the like, the names of the First Nature?  What then?  Can you conceive of Spirit apart from motion and diffusion; or of Fire without its fuel and its upward motion, and its proper colour and form?  Or of Light unmingled with air, and loosed from that which is as it were its father and source?  And how do you conceive of a mind?  Is it not that which is inherent in some person not itself, and are not its movements thoughts, silent or uttered?  And Reason…what else can you think it than that which is either silent within ourselves, or else outpoured (for I shrink from saying loosed)?  And if you conceive of Wisdom, what is it but the habit of mind which you know as such, and which is concerned with contemplations either divine or human?  And Justice and Love, are they not praiseworthy dispositions, the one opposed to injustice, the other to hate, and at one time intensifying themselves, at another relaxed, now taking possession of us, now leaving us alone, and in a word, making us what we are, and changing us as colours do bodies?  Or are we rather to leave all these things, and to look at the Deity absolutely, as best we can, collecting a fragmentary perception of It from Its images?  What then is this subtile thing, which is of these, and yet is not these, or how can that Unity which is in its Nature uncomposite and incomparable, still be all of these, and each one of them perfectly?  Thus our mind faints to transcend corporeal things, and to consort with the Incorporeal, stripped of all clothing of corporeal ideas, as long as it has to look with its inherent weakness at things above its strength.  For every rational nature longs for God and for the First Cause, but is unable to grasp Him, for the reasons I have mentioned.  Faint therefore with the desire, and as it were restive and impatient of the disability, it tries a second course, either to look at visible things, and out of some of them to make a god…(a poor contrivance, for in what respect and to what extent can that which is seen be higher and more godlike than that which sees, that this should worship that?) or else through the beauty and order of visible things to attain to that which is above sight; but not to suffer the loss of God through the magnificence of visible things.
