Time, as it grows old, teaches all things.

Memory is the mother of all wisdom

Wisdom comes through suffering.
Trouble, with its memories of pain,
Drips in our hearts as we try to sleep,
So men against their will
Learn to practice moderation.
Favours come to us from gods.

It is good even for old men to learn wisdom.

Time brings all things to pass.

By Time and Age full many things are taught.
