Question

Let me not to the marriage of true minds Admit impediments. Love is not love Which alters when it alteration finds, Or bends with the remover to remove… If this be error, and upon me proved, I never writ, nor no man ever loved. In Sonnet 116 by William Shakespeare, how does the Speaker’s mood change from the first quatrain to the final couplet of the poem?

Answer 1

 The speaker starts with declarations of certainty about love and marriage of true minds, believing it should not change nor accept that any difficulty cause it to cease. But, in the end, the speaker seems not so sure as before ("if this be error"), then he goes on to admit, if such be proved, that he never wrote about it nor "any man ever loved".
