He has opened the way of wisdom to mortals, by proclaiming as a sovereign law: By suffering comes understanding

Zeus, whose will has marked for manThe sole way where wisdom lies;Ordered one eternal plan:Man must suffer to be wise.Head-winds heavy with past illStray his course and cloud his heart:Sorrow takes the blind soul's part -Man grows wise against his will.For powers who rule from thrones aboveBy ruthlessness commend their love.

Wisdom cometh by suffering.

The wisest of the wise may err.

Of prosperity mortals can never have enough.
