莎士比亚十四行诗118
With eager compounds we our palate urge,
As to prevent our maladies unseen
We sicken to shun sickness when we purge;
Even so, being full of your ne'er-cloying sweetness,
To bitter sauces did I frame my feeding,
And, sick of welfare, found a kind of meetness
To be diseased ere that there was true needing.
Thus policy in love, tanticipate
The ills that were not, grew to faults assured,
And brought to medicine a healthful state,
Which, rank of goodness, would by ill be cured.
But thence I learn, and find the lesson true,
Drugs poison him that so fell sick of you.
