15. Now listen, so far as the present time requires, while from that similitude of sensible things I now teach also something concerning God. Namely, God is intelligible, not sensible, intelligible also are those demonstrations of the schools; nevertheless they differ very widely. For as the earth is visible, so is light; but the earth, unless illumined by light, cannot be seen. Therefore those things also which are taught in the schools, which no one who understands them doubts in the least to be absolutely true, we must believe to be incapable of being understood, unless they are illuminated by somewhat else, as it were a sun of their own. Therefore as in this visible sun we may observe three things: that he is, that he shines, that he illuminates: so in that God most far withdrawn whom thou wouldst fain apprehend, there are these three things: that He is, that He is apprehended, and that He makes other things to be apprehended. These two, God and thyself, I dare promise that I can teach thee to understand. But give answer how thou receivest these things, as probable, or as true? A. As probable certainly; and, as I must own, I have been hoping more: for excepting those two illustrations of the line and the globe, nothing has been said by thee which I should dare to say that I know. R. It is not to be wondered at: for nothing has been yet so set forth, as that it exacts of thee perception.
CAPUT VIII. Quae ad cognoscendum Deum necessaria.
15. Nunc accipe, quantum praesens tempus exposcit, ex illa similitudine sensibilium etiam de Deo aliquid nunc me docente . Intelligibilis nempe Deus est, intelligibilia etiam illa disciplinarum spectamina; tamen plurimum differunt. Nam et terra visibilis, et lux; sed terra, nisi luce illustrata, videri non potest. Ergo et illa quae in disciplinis traduntur, quae quisquis intelligit, verissima esse nulla dubitatione concedit, credendum est ea non posse intelligi, nisi ab alio quasi suo sole illustrentur. Ergo quomodo in hoc sole tria quaedam licet animadvertere; quod est, quod fulget, quod illuminat: ita in illo secretissimo Deo quem vis intelligere, tria quaedam sunt; quod est, quod intelligitur, et quod caetera facit intelligi. Haec duo, id est, teipsum et Deum, ut intelligas, docere te audeo. Sed responde quomodo haec acceperis; ut probabilia, an ut vera? A. Plane ut probabilia; et in spem, quod fatendum est, majorem surrexi: nam praeter illa duo de linea et pila, nihil abs te dictum est quod me scire audeam dicere. R. Non est mirandum: non enim quidquam est adhuc ita expositum, ut abs te sit flagitanda perceptio.
