The man whose whole life is spent in performing a few simple operations, of which the effects are perhaps always the same, or very nearly the same, has no occasion to exert his understanding or to exercise his invention in finding out expedients for removing difficulties which never occur. He naturally loses, therefore, the habit of such exertion, and generally becomes as stupid and ignorant as it is possible for a human creature to become.

Are you in earnest resolved never to barter your liberty for the lordly servitude of a court, but to live free, fearless, and independent? There seems to be one way to continue in that virtuous resolution; and perhaps but one.

Masters are always and everywhere in a sort of tacit, but constant and uniform combination, not to raise the wages of labor above their actual price.
