Sure, her offence
Must be of such unnatural degree
That monsters it, or your forevouched affection
Fall into taint; which to believe of her
Must be a faith that reason without miracle
Should never plant in me.
– William Shakespeare
King Lear, Act 1, Scene 1. The King of France confronts Lear about his newly dowerless daughter Cordelia. He says that her offense must have been so unnatural to make Lear’s affection for her turn rotten. But he adds that it would take a miracle to make him believe she could do something like that.
