In which poem does Waller suggest that wisdom comes with old age. ( MEG 101 ) ( THE EARLY AUGUSTANS )

Waller suggests that wisdom comes with old age in his poem "Of a War with Spain," where he writes:

"But should our navy, too, be vanquished here,

Who could in other quarrels persevere?

Who else shall be by long experience wise?

Or who endure in council, when those eyes

That guide the state are dim, and cannot see

Those dangers that will on the younger be?"
