For the thoughts of mortal men are miserable, and our devices are but uncertain.
All Commentaries on Wisdom of Solomon 9:14 Go To Wisdom of Solomon 9
Fulgentius of Ruspe
"And our reflections are uncertain." Foresight is uncertain with regard to things that are uncertain, and those things of which we do not have secure possession are uncertain. Every day, without wanting to, we can lose what we cannot possess forever. Thus the reflections of mortals are uncertain when their souls remain enthralled by things, the possession of which can be taken from the possessor without his consent or from which the possessor can be deprived without him wishing it.
