… is from page 481 of the 1964 W. Hayden Boyers translation, published by the Foundation for Economic Education, of Frederic Bastiat ‘s 1850 treatise, Economic Harmonies  (available on-line here ):
In order to produce, we must direct all our faculties toward the conquest of Nature; for it is Nature that must be fought, mastered, and subjugated. That is why iron beaten into a plowshare is the emblem of production.
In order to plunder, we must direct all our faculties toward the conquest of men; for they are the ones we must fight, kill, or enslave. That is why iron beaten into a sword is the emblem of plunder.
