The liberty of wording
Or: Are we free to be free?
Or: The tyranny of the liberty of meaning.
We all declare for liberty; but in using the same word we do not all mean the same thing. With some the word liberty may mean for each man to do as he pleases with himself, and the product of his labor; while with others, the same word may mean for some men to do as they please with other men, and the product of other men’s labor. Here are two, not only different, but incompatible things, called by the same name — liberty. And it follows that each of the things is, by the respective parties, called by two different and incompatible names — liberty and tyranny.
