16. [XV.]—We Need Divine Aid in the Use of Our Powers. Illustration from Sight.
Now what is the use of his examples, if they do not really accomplish his own promise of making his meaning clearer to us;38 See above, ch. 5 [iv.]. not, indeed, that we are bound to admit their sense, but that we may discover more plainly and openly what is his drift and purpose in using them? “That we are able,” says he, “to see with our eyes is not of us; but it is of us that we make a good or a bad use of our sight.” Well, there is an answer for him in the psalm, in which the psalmist says to God, “Turn Thou away mine eyes, that they behold not iniquity.”39 Ps. cxix. 37. Now although this was said of the eyes of the mind, it still follows from it, that in respect of our bodily eyes there is either a good use or a bad use that may be made of them: not in the literal sense merely of a good sight when the eyes are sound, and a bad sight when they are bleared, but in the moral sense of a right sight when it is directed towards succouring the helpless, or a bad sight when its object is the indulgence of lust. For although both the pauper who is succoured, and the woman who is lusted after, are seen by these external eyes; it is after all from the inner eyes that either compassion in the one case or lust in the other proceeds. How then is it that the prayer is offered to God, “Turn Thou away mine eyes, that they behold not iniquity”? Or why is that asked for which lies within our own power, if it be true that God does not assist the will?
CAPUT XV.
16. Quid sibi ergo volunt exempla, nisi quia revera nobis ejus sensum fecerunt, sicut pollicitus est, clariorem; non ut ea sentire debeamus, sed ut id quod ipse sensit, manifestius apertiusque noscamus? «Quod possumus,» inquit, «videre oculis, nostrum non est: quod vero bene aut male videmus, hoc nostrum est.» Respondeat illi 0369 Psalmus, ubi Deo dicitur, Averte oculos meos, ne videant vanitatem (Psal. CXVIII, 37). Quod et si de oculis mentis dictum est, inde utique procedit in hos oculos carnis, vel bene videre, vel male: non quemadmodum dicuntur bene videre sanis oculis intuentes, et male, lippientes; sed bene videre ad subveniendum, male videre ad concupiscendum. Quamvis enim per hos exteriores oculos videatur et pauper cui subvenitur, et mulier quae concupiscitur; tamen ex interioribus ad male vel bene videndum misericordia vel libido procedit. Cur ergo dicitur Deo, Averte oculos meos, ne videant vanitatem? Cur petitur quod ad nostram pertinet potestatem, si Deus non adjuvat voluntatem?
