“My success and my misfortunes, the bright and the dark days I have gone through, everything has proved to me that in this world, either physical or moral, good comes out of evil just as well as evil comes out of good.”

Memoirs of J. Casanova de Seingalt (1894)
Context: My success and my misfortunes, the bright and the dark days I have gone through, everything has proved to me that in this world, either physical or moral, good comes out of evil just as well as evil comes out of good. My errors will point to thinking men the various roads, and will teach them the great art of treading on the brink of the precipice without falling into it. It is only necessary to have courage, for strength without self-confidence is useless. I have often met with happiness after some imprudent step which ought to have brought ruin upon me, and although passing a vote of censure upon myself I would thank God for his mercy. But, by way of compensation, dire misfortune has befallen me in consequence of actions prompted by the most cautious wisdom. This would humble me; yet conscious that I had acted rightly I would easily derive comfort from that conviction.
