Vices are simply the errors which a man makes in his search after his own happiness. Unlike crimes, they imply no malice toward others, and no interference with their persons or property.

Vices are usually pleasurable, at least for the time being, and often do not disclose themselves as vices, by their effects, until after they have been practised for many years; perhaps for a lifetime.

For a government to declare a vice to be a crime, and to punish it as such, is an attempt to falsify the very nature of things. It is as absurd as it would be to declare truth to be falsehood, or falsehood truth.
