letting "I dare not" wait upon "I would"?

Prithee, peace.

I dare do all that may become a man.

Who dares do more is none.

What beast was't, then,

that made you break this enterprise to me?

When you durst do it, then you were a man.

And to be more than what you were,

you would be so much more the man.

I have given suck

and know how tender 'tis to love the babe that milks me.

I would, while it was smiling in my face,

have plucked my nipple from his boneless gums

and dashed the brains out

had I so sworn, as you have done, to this.

If we should fail?

We fail.

But screw your courage to the sticking place

and we'll not fail.
