(7) But this much is enough, since it is impossible for anyone to dispute the nature of the words I have just spoken about the blessed, imperishable, true God. Now, if anyone wants to believe the words set down (here), let him go from what is hidden to the end of what is visible, and this Thought will instruct him how faith in those things that are not visible was found in what is visible. This is a principle of knowledge.

(10) These things should seem to thee, Asclepius, if thou dost understand them, true; but if thou dost not understand, things not to be believed. To understand is to believe, to not believe is not to understand. My word (logos) doth go before [thee] to the truth. But mighty is the mind, and when it hath been led by word up to a certain point, it hath the power to come before [thee] to the truth. And having thought o'er all these things, and found them consonant with those which have already been translated by the reason, it hath [e'en now] believed, and found its rest in that Fair Faith. To those, then, who by God['s good aid] do understand the things that have been said [by us] above, they're credible; but unto those who understand them not, incredible. Let so much, then, suffice on thought-and-sense.
