So many hundred hands in this mill; so many hundred horse steam power. It is known, to the force of a single pound weight, what the engine will do; but, not all the calculators [in the world] can tell me the capacity for good or evil, for love or hatred, […] in the soul of one of these its quiet servants, with the composed faces and the regulated actions.
Charles Dickens, Hard Times (1854)
