The Knoxville blog No Silence Here, via Blue Collar Muse, offers a lengthy libertarian quote list. I usually dislike quotation lists, as the quotes are often out of context, and consequently misused.
Still, there are some gems here, including this from Tacitus:
“The more corrupt the state, the more it legislates.”
The quotation is a paraphrase from the Annals, Book III, following an observation that tribunes used legislation to manipulate common people.
