As is right, then, knowledge itself loves and teaches the ignorant, and instructs the whole creation to honour God Almighty. And if such an one teaches to love God, he will not hold virtue as a thing to be lost in any case, either awake or in a dream, or in any vision; since the habit never goes out of itself by falling from being a habit. Whether, then, knowledge be said to be habit or disposition; on account of diverse sentiments never obtaining access, the guiding faculty, remaining unaltered, admits no alteration of appearances by framing in dreams visionary conceptions out of its movements by day. Wherefore also the Lord enjoins “to watch,” so that our soul may never be perturbed with passion, even in dreams; but also to keep the life of the night pure and stainless, as if spent in the day. For assimilation to God, as far as we can, is preserving the mind in its relation to the same things. And this is the relation of mind as mind.
