THE LIFE of man
Is an arrow’s flight,
Out of darkness
Into light,
And out of light
Into darkness again;
Perhaps to pleasure,
Perhaps to pain!

There must be Something,
Above, or below;
Somewhere unseen
A mighty Bow,
A Hand that tires not,
A sleepless Eye
That sees the arrows
Fly, and fly;
One who knows
Why we live—and die.

Richard Henry Stoddard
