what does proctor mean in his comment at the end of the act

At the end of the play Danforth wants to know why Proctor just won't confess and be done with the trial. It is the easiest way out of this tragedy for both John and his wife Elizabeth. In response Proctor cries out,

"Because it is my name! Because I cannot have another in my life. Because I am not worth the dust on the feet of them that hang! How may I live without my name? I have given you my soul, leave me my name!"

He refuses to sign the confession because, in the end, his name is the only truth he has left. He was not faithful to his wife and has worked hard to make amends. After all the lies and deceit flying around Salem, John's name is all he has left of his self-worth.
