Never support two weaknesses at the same time. It's your combination sinners - your lecherous liars and your miserly drunkards - who dishonor the vices and bring them into bad repute.

Nurse one vice in your bosom. Give it the attention it deserves and let your virtues spring p modestly around it. Then you'll have the miser who's no liar; and the drunkard who's the benefactor of the whole city.

Virtue practiced to be seen is not real virtue; vice which fears to be seen is real vice

Virtue by calculation is the virtue of vice

Though ambition in itself is a vice, it often is also the parent of virtue.

Any virtue taken to the extreme becomes a vice; unfortunately it doesn't work the other way.
