Quam multis amaritudinibus humanæ felicitatis dulcedo respersa est!
(Boethius, lib. ii. prose 4.)
Anxia enim res est humanorum conditio bonorum, et quæ vel nunquam tota proveniat, vel nunquam perpetua subsistat.
(Ib.)
O, brotel wele of mannes joie unstable!
With what wight so thow be, or how thow pleye,
Oither he woot that thow joie art muable,
Or woot it nought, it mot ben on of tweyen:
Now if he woot it not, how may he seyen
That he hath veray joie and selynesse,
