Sleep steals on us even like his brother Death—
We know not when it comes—we know it must come—
We may affect to scorn and to contemn it,
For ’tis the highest pride of human misery
To say it knows not of an opiate;
Yet the reft parent, the despairing lover,
Even the poor wretch who waits for execution,
Feels this oblivion, against which he thought
His woes had arm’d his senses, steal upon him,
And through the fenceless citadel—the body—
Surprise that haughty garrison—the mind.
