A’sadist’ of her kind is an artist in evil, which a wholly wicked person could not be, for in that case the evil would not  have been external, it would have seemed quite natural to her, and would not even have been distinguishable from herself; and as for virtue, respect for the dead, filial obedience, since she would never have practised the cult of these things, she would take no impious delight in their profanation. ‘Sadists’ of Mlle. Vinteuil’s sort are creatures so purely sentimental, so virtuous by nature, that even sensual pleasure appears to them as something bad, a privilege reserved for the wicked. And when they allow themselves for a moment to enjoy it they endeavour to impersonate, to assume all the outward appearance of wicked people, for themselves and their partners in guilt, so as to gain the momentary illusion of having escaped beyond the control of their own gentle and scrupulous natures into the inhuman world of pleasure.

It was not evil that gave her the idea of pleasure, that seemed to her attractive; it was pleasure, rather, that seemed evil. And as, every time that she indulged in it, pleasure came to her attended by evil thoughts such as, ordinarily, had no place in her virtuous mind, she came at length to see in pleasure itself something diabolical, to identify it with Evil.
