“These workers did not serve, they worked. Their honour was absolute, as is characteristic of honour. It was imperative that the rung of a chair be well made. That was understood. It was a principle. It did not have to be well made in order to receive one's salary, or in exchange for a salary. It did not have to be well made for the sake of the boss, or for the sake of connoisseurs, or for the sake of the boss' clients. It had to be well made in and for itself, in its very being. A tradition, […] a history, an absolute, an honour wanted that that chair rung be well made. Every part in the chair, that was not visible, was exactly as perfectly made as the parts that were visible. It is the very principle of the cathedrals.”

Charles Péguy, L’Argent, 1913.
