Hypocrisy is not generally a social sin, but a virtue.

You can't have virtue without sin. What I'm after is having my characters' virtues defined by how they operate in a very sinful environment. That's how you test people.

That vice pays homage to virtue is notorious; we call it hypocrisy

Yes, I laugh at all mankind, and the imposition that they dare to practice when they talk of hearts. I laugh at human passions and human cares, vice and virtue, religion and impiety; they are all the result of petty localities, and artificial situation. One physical want, one severe and abrupt lesson from the colorless and shriveled lip of necessity, is worth all the logic of the empty wretches who have presumed to prate it, from Zeno down to Burgersdicius. It silences in a second all the feeble sophistry of conventional life, and ascetical passion.

Hypocrisy is a tribute that vice pays to virtue.

All good things were at one time bad things; every original sin has developed into an original virtue.
