De Somniis (lib. i-ii)

And this announces three most glorious things to the soul; one, the destruction of the passions of Egypt; another, that this has taken place in no other spot than near the salt and bitter springs, as if on the shore of the sea, by which sophistical reason, that enemy of virtue, is poured forth; and, lastly, the sight of the disaster.

For no glorious thing can be invisible, but should be brought to the light and brilliancy of the sun. For so also the contrary, namely evil, should be thrust into deep darkness, and should be accounted deserving of night. And may it indeed by chance happen to some one to behold this: but what is really good should be always beheld by more piercing eyes. And what is so good as that what is good should live, and what is evil should die?
