Speculation: We Players Macbeth Rehearsal at Fort Point…
MACBETH
Canst thou not minister to a mind diseased,
Pluck from the memory a rooted sorrow,
Raze out the written troubles of the brain
And with some sweet oblivious antidote
Cleanse the stuff’d bosom of that perilous stuff
Which weighs upon the heart?
Doctor
Therein the patient
Must minister to himself.
Shakespeare, Macbeth, 5,3
