De Somniis (lib. i-ii)

Now those which admit of a remedy are set down as the easiest and the first; but those which are irremediable are altogether terrible, and are the last of all, being so far [*](Deuteronomy xxxii. 32. ) [*](Deuteronomy xxv. 13. )

And as, in my notions, wisdom begins to benefit a man in small matters, and ends at last in the absolute perfection of all well-doing, so, in the same manner folly, constraining the soul from above and leading it away from instruction by small degrees, establishes it at last at a long distance from right reason, and finally leads it to the extreme point, and utterly overthrows it.
