The Marquis de Sade, in a letter to his wife.

I am a libertine, but I am not a criminal nor a murderer, and since I am compelled to set my apology alongside my vindication, I shall therefore say that it might well be possible that those who condemn me as unjustly as I have been might themselves be unable to offset the infamies by good works as clearly established as those I can contrast to my errors. I am a libertine, but three families residing in your area have for five years lived off my charity, and I have saved them from the farthest depths of poverty. I am a libertine, but I have saved a deserter from death, a deserter abandoned by his entire regiment and by his colonel. I am a libertine, but at Evry, with your whole family looking on, I saved a child—at the risk of my life—who was on the verge of being crushed beneath the wheels of a runaway horse-drawn cart, by snatching the child from beneath it. I am a libertine, but I have never compromised my wife’s health. Nor have I been guilty of the other kinds of libertinage so often fatal to children’s fortunes: have I ruined them by gambling or by other expenses that might have deprived them of, or even by one day foreshortened, their inheritance? Have I managed my own fortune badly, as long as I have had a say in the matter? In a word, did I in my youth herald a heart capable of the atrocities of which I today stand accused?... How therefore do you presume that, from so innocent a childhood and youth, I have suddenly arrived at the ultimate of premeditated horror? No, you do not believe it. And yet you who today tyrannize me so cruelly, you do not believe it either: your vengeance has beguiled your mind, you have proceeded blindly to tyrannize, but your heart knows mine, it judges it more fairly, and it knows full well it is innocent.
