"Lately people are saying that the reason for the success of manufacturing is the Division of labor. We say "Division of labor," but this term is incorrect. In our society it is not labor that is divided, but human beings — these are divided into human particles, broken into small pieces, ground into dust: in a factory one man makes only one minute portion of an article, because that tiny fragment of reason which he retains is insufficient to make a complete pin or a complete nail, and is exhausted in the task of pointing the pin or heading the nail. It is true that it is good and desirable to make as many pins daily as possible, but if we realized the material with which we finish them, we would realize how unprofitable it all is. It is unprofitable because we polish them with the dust of the human soul."
