"The chief business of my life has always been to indulge my senses; I never knew anything of greater importance. I felt myself born for the fair sex, I have ever loved it dearly, and I have been loved by it as often and as much as I could."

"An ancient author tells us somewhere, with the tone of a pedagogue, if you have not done anything worthy of being recorded, at least write something worthy of being read. It is a precept as beautiful as a diamond of the first water cut in England, but it cannot be applied to me, because I have not written either a novel, or the life of an illustrious character. Worthy or not, my life is my subject, and my subject is my life. I have lived without dreaming that I should ever take a fancy to write the history of my life, and, for that very reason, my Memoirs may claim from the reader an interest and a sympathy which they would not have obtained, had I always entertained the design to write them in my old age, and, still more, to publish them."

"I have written the history of my life, and I have a perfect right to do so; but am I wise in throwing it before a public of which I know nothing but evil? No, I am aware it is sheer folly, but I want to be busy, I want to laugh, and why should I deny myself this gratification?"

"In spite of a good foundation of sound morals, the natural offspring of the Divine principles which had been early rooted in my heart, I have been throughout my life the victim of my senses; I have found delight in losing the right path, I have constantly lived in the midst of error, with no consolation but the consciousness of my being mistaken. Therefore, dear reader, I trust that, far from attaching to my history the character of impudent boasting, you will find in my Memoirs only the characteristic proper to a general confession, and that my narratory style will be the manner neither of a repenting sinner, nor of a man ashamed to acknowledge his frolics. They are the follies inherent to youth; I make sport of them, and, if you are kind, you will not yourself refuse them a good-natured smile. You will be amused when you see that I have more than once deceived without the slightest qualm of conscience, both knaves and fools. As to the deceit perpetrated upon women, let it pass, for, when love is in the way, men and women as a general rule dupe each other. But on the score of fools it is a very different matter. I always feel the greatest bliss when I recollect those I have caught in my snares, for they generally are insolent, and so self-conceited that they challenge wit. We avenge intellect when we dupe a fool, and it is a victory not to be despised for a fool is covered with steel and it is often very hard to find his vulnerable part. In fact, to gull a fool seems to me an exploit worthy of a witty man. I have felt in my very blood, ever since I was born, a most unconquerable hatred towards the whole tribe of fools, and it arises from the fact that I feel myself a blockhead whenever I am in their company. I am very far from placing them in the same class with those men whom we call stupid, for the latter are stupid only from deficient education, and I rather like them. I have met with some of them — very honest fellows, who, with all their stupidity, had a kind of intelligence and an upright good sense, which cannot be the characteristics of fools. They are like eyes veiled with the cataract, which, if the disease could be removed, would be very beautiful."

"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."

"The reader of these Memoirs will discover that I never had any fixed aim before my eyes, and that my system, if it can be called a system, has been to glide away unconcernedly on the stream of life, trusting to the wind wherever it led. How many changes arise from such an independent mode of life!"

"Man is free; yet we must not suppose that he is at liberty to do everything he pleases, for he becomes a slave the moment he allows his actions to be ruled by passion. The man who has sufficient power over himself to wait until his nature has recovered its even balance is the truly wise man, but such beings are seldom met with."

"Man is free, but his freedom ceases when he has no faith in it; and the greater power he ascribes to faith, the more he deprives himself of that power which God has given to him when He endowed him with the gift of reason. Reason is a particle of the Creator's divinity. When we use it with a spirit of humility and justice we are certain to please the Giver of that precious gift."

"I believe in the existence of an immaterial God, the Author and Master of all beings and all things, and I feel that I never had any doubt of His existence, from the fact that I have always relied upon His providence, prayed to Him in my distress, and that He has always granted my prayers. Despair brings death, but prayer does away with despair; and when a man has prayed he feels himself supported by new confidence and endowed with power to act. As to the means employed by the Sovereign Master of human beings to avert impending dangers from those who beseech His assistance, I confess that the knowledge of them is above the intelligence of man, who can but wonder and adore."

"I will begin with this confession: whatever I have done in the course of my life, whether it be good or evil, has been done freely; I am a free agent."

"Great God, and you witnesses of my death, I have lived as a philosopher, and I die as a Christian."

"[Matrimony] is the grave of love."

"[Marriage] is the tomb of love."

"Man is free, but his freedom ceases when he has no faith in it[.]"

"Man is a free agent; but he is not free if he does not believe it[.]"

"Man is free; but not unless he believes he is[.]"

"Malipiero's advice to Casanova.] If you wish your audience to cry, you must shed tears yourself, but if you wish to make them laugh you must contrive to look as serious as a judge."

"I have always had such sincere love for truth, that I have often begun by telling stories for the purpose of getting truth to enter the heads of those who could not appreciate its charms."
