If we should fail?
But screw your courage to the sticking-place,
And we’ll not fail. When Duncan is asleep—
Whereto the rather shall his day’s hard journey
Soundly invite him—his two chamberlains
Will I with wine and wassail so convince
That memory, the warder of the brain,
Shall be a fume, and the receipt of reason
A limbeck only: when in swinish sleep
Their drenched natures lie as in a death,
What cannot you and I perform upon
The unguarded Duncan? what not put upon
His spongy officers, who shall bear the guilt
Of our great quell?
MACBETH, ACT I.
