Arthur Hugh Clough Quote

Come back again, old heart! Ah me!
Methinks in those thy coward fears
There might, perchance, a courage be,
That fails in these the manlier years;
Courage to let the courage sink,
Itself a coward base to think,
Rather than not for heavenly light
Wait on to show the truly right.

The Higher Courage, st. 7 (1840).
