if this be error and upon me proved, i never writ, nor no man ever loved.

What is your question?

I think its a sentence from Shakespeare's Sonnet 116.

The line you mentioned is from Sonnet 116, one of William Shakespeare's famous sonnets. It expresses the idea that if the speaker's understanding of love is proven to be mistaken, then he never wrote anything, and no one has ever experienced true love.

Is there anything in particular you would like to know or discuss about this quote?
