Is my happiness to be thus blasted for life?
Have I no redress ?" Of course you have.

All the law, written and unwritten, is on your side.
The intention and not the act constitutes crime--in other words, constitutes the deed.

If you call your bosom friend a fool, and intend it for an insult, it is an insult; but if you do it playfully, and meaning no insult, it is not an insult.

If you discharge a pistol accidentally, and kill a man, you can go free, for you have done no murder; but if you try to kill a man, and manifestly intend to kill him, but fail utterly to do it, the law still holds that the intention constituted the crime, and you are guilty of murder.

Ergo, if you had married Edwitha accidentally, and without really intending to do it, you would not actually be married to her at all, because the act of marriage could not be complete without the intention.
