What is the significance of Proctor's speech in Act IV of The Crucible?

[zk4586]

Anybody have a copy of the play? I'm hoping someone could type out the first part of Proctor's speech during Act IV, when he realizes that he can't lie to save himself. It starts off like:

"Because it is my name! Because I can never have another in my life! Because I am not worth the dust on the feet of those that have hanged..."

If you need to know still it is

"Because it is my name! Because i cannot have another in my life! Because i lie and sign myself to lies! 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"

if it is any use
