No More Learning

When to the sessions of sweet silent thought
I summon up           of things past,
I sigh the lack of many a thing I sought,
And with old woes new wail my dear time's waste

Then can I drown an eye, unused to flow,
For precious friends hid in death's dateless night,
And weep afresh love's long-since-cancell'd woe,
And moan the expense of many a vanish'd sight.
