Shakespeare’s Sonnet 147:
My love is as a fever longing still,
For that which longer nurseth the disease;
Feeding on that which doth preserve the ill,
The uncertain sickly appetite to please.
My reason, the physician to my love,
Angry that his prescriptions are not kept,
Hath left me, and I desperate now approve
Desire is death, which physic did except.
Past cure I am, now Reason is past care,
And frantic-mad with evermore unrest;
My thoughts and my discourse as madmen’s are,
At random from the truth vainly expressed;
For I have sworn thee fair, and thought thee bright,
Who art as black as hell, as dark as night.
Canst thou, O cruel! say I love thee not,
When I against myself with thee partake?
Do I not think on thee, when I forgot
Am of my self, all tyrant, for thy sake?
Who hateth thee that I do call my friend,
On whom frown’st thou that I do fawn upon,
Nay, if thou lour’st on me, do I not spend
Revenge upon myself with present moan?
What merit do I in my self respect,
That is so proud thy service to despise,
When all my best doth worship thy defect,
Commanded by the motion of thine eyes?
But, love, hate on, for now I know thy mind,
Those that can see thou lov’st, and I am blind.
O! from what power hast thou this powerful might,
With insufficiency my heart to sway?
To make me give the lie to my true sight,
And swear that brightness doth not grace the day?
Whence hast thou this becoming of things ill,
That in the very refuse of thy deeds
There is such strength and warrantise of skill,
That, in my mind, thy worst all best exceeds?
Who taught thee how to make me love thee more,
The more I hear and see just cause of hate?
O! though I love what others do abhor,
With others thou shouldst not abhor my state:
If thy unworthiness raised love in me,
More worthy I to be beloved of thee.
