I'm weary of conjectures,—this must end 'em.

Thus am I doubly armed: my death and life,

My bane and antidote, are both before me:

This in a moment brings me to an end;

But this informs me I shall never die.

The soul, secured in her existence, smiles

At the drawn dagger, and defies its point.

The stars shall fade away, the sun himself

Grow dim with age, and Nature sink in years;

But thou shalt flourish in immortal youth,

Unhurt amidst the war of elements,

The wrecks of matter, and the crush of worlds.

Joseph Addison (1672-1719): Cato. Act v. Sc. 1.

  Doct.      Not so sick, my lord,

As she is troubled with thick-coming fancies,

That keep her from her rest.

  Macb.        Cure her of that.

Canst thou not minister to a mind diseas'd,

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?

  Doct.        Therein the patient

Must minister to himself.

  Macb.  Throw physic to the dogs: I 'll none of it.

William Shakespeare (1564-1616): Macbeth. Act v. Sc. 3.
