LADY MACBETH. Glamis thou art. and Cawdor, and shalt be
What thou art promised. Yet
do I fear thy nature;
It is too full o' th' milk of human kindness
To catch the
nearest way: thou wouldst be great,
Art not without ambition, but without
The illness should attend it. What thou wouldst
highly,
That wouldst thou holily; wouldst not play false,
And yet wouldst wrongly win. Thou'ld'st have, great Glamis,
That which cries, "Thus thou must do." if thou have it,
And that which rather thou dost fear to do,
Than wishest should be undone. Hie thee hither,
That I may pour my spirits in thine ear
And chastise with the valor of my tongue
All that impedes thee from the golden round,
Which fate and metaphysical aid doth seem
To have thee crowned withal.
•William Shakespeare, Macbeth, Act l, scene v
