Having examined in the preceding treatise what has been said by the lawgiver about wine and the nakedness which attends upon it, we will now begin to connect the the following essay with the statements advanced in that work.
Now in the sacred scriptures we come to the following words immediately after the account we have just been examining, "And Noah awoke from his wine, and knew all that his younger son had done to him." Genesis ix. 23. Sobriety is confessed to be a most advantageous thing, not only for souls but also for bodies, for it drives away the diseases which arise from immoderate repletion, and it sharpens the outward senses to an exceeding degree of acuteness, and it altogether prevents
 Genesis ix. 23. 
 
bodies from being weighed down so as to fall, but keeps them light, and raises them up, and incites them to the exercise of their appropriate energies, implanting in every part a promptness and vigour; and in short, sobriety is the cause of exactly as many good things, as drunkenness, on the contrary, is of evils.
 Since then sobriety is most advantageous to those bodies to which the drinking of wine is naturally suitable, is it not much more so to souls, with which all perishable food is inconsistent; for what thing in human nature can be more noble than a sober mind? what glory can be more glorious? what wealth can be more rich? what authority more powerful? what strength more vigorous? of all admirable things what can be more admirable? Let there only be the eye of the soul fit to act, which is able to penetrate every where and to open every thing, being in no part hindered or dimmed by the suffusion of its own moisture; for being then most exceedingly sharp-sighted as to its comprehension, and looking into wisdom itself, it will meet with images such as are intelligible only by the intellect, the contemplation of which attracts the soul and will not suffer it any longer to turn aside to the objects which belong to the outward senses.
 And why should we wonder if there is no created thing equal in honour to a man who is sober in his soul, and gifted with acute vision? for the eyes of the body and the light which is appreciable by the outward senses are honoured in an excessive degree by all of us. Accordingly, many who have lost their sight, have voluntarily also thrown away life, thinking as far as they were concerned, that death itself was a lighter evil than such deprivation. In proportion then as the soul is superior to the body, in the same proportion also is the mind better than the eyes; and the mind while it is free from injury and imperfection, not being oppressed by any of the iniquities or passions which are produced by insane drunkenness, renounces sleep as a thing which causes forgetfulness and hesitation in what is to be done; but it embraces wakefulness, and uses acuteness of vision, with respect to every object worthy of being beheld, being kept awake by exceedingly perfect memory, and committing actions which are in accordance with the knowledge that it acquires.
