Dangerous Liaisons by Pierre Choderlos de Laclos

I never yet doubted, my young and charming friend, of your friendship for me, nor of the interest you take in all my concerns. It is not to clear up this point, on which I hope we are forever agreed, that I reply to your answer; but I think myself obliged to say a word or two relative to Viscount Valmont.

I must own, I did not expect to meet such a name in a letter from you. How is it possible there can be any communication between you and him? You do not know that man. Where did you find the idea you have imbibed of the heart of a libertine? You tell me of his uncommon candour; yes, truly, Valmont's candour is very uncommon. He is yet more false and dangerous than he is lovely and seducing: never since his earliest youth, has he taken a step, or spoke a word, without a design; and never formed a design that was not criminal or improper. My dear friend, you know me; you know that of all the virtues I endeavour to acquire, indulgence is the one I cherish most; and if Valmont had been hurried away by the impetuosity of his passions, or if, like a thousand more at his time of life, he had been seduced by the errors of youth, I would have compassionated his person, blamed his conduct, and have patiently waited until time, the happy maturer of green years, should have made him fit for the society and esteem of worthy people: but that's not Valmont's case; his conduct is the result of principle; he calculates how far a man can proceed in villainy without risking reputation, and has chosen women for his victims, that his sacrifices may be wicked and cruel without danger. I shall not dwell on the numbers he has seduced; but how many has he not utterly undone? Those scandalous anecdotes never come within the sphere of your retired and regular course of life. I could, however, relate you some that would make you shudder; but your mind, pure as your soul, would be defiled with such descriptions: convinced, as I am, that Valmont will never be an object of danger to you, such armour is unnecessary to guard you. I can't, however, refrain telling you, that successful or not, no woman he ever yet dangled after, but had reason to repent her folly. The only exception to this general rule is the Marchioness de Merteuil; she alone has been capable not only of resisting, but of completely defeating his wickedness.
