Marriage, in life, is like a duel in the midst of a battle.

It was in the Papal States that I studied the Roman Question. I traveled over every part of the country; I conversed with men of all opinions, examined things very closely, and collected my information...

I have been further enlightened by the conversation and correspondence of some illustrious Italians, whom I would gladly name, were I not afraid of exposing them to danger.

I fight fairly, and in good faith.

But as the Pope has a long arm, which might reach me in France, I have gone a little out of the way to tell him the plain truths contained in these pages.
