“What a thing it is to see the order which prevails throughout his business! By means of this he can at any time survey the general whole, without needing to perplex himself in the details. What advantages does he derive from the system of book-keeping by double entry! It is among the finest inventions of the human mind; every prudent master of a house should introduce it into his economy.”

From Wilhelm Meister’s Apprenticeship, Book 1, Chapter X, published in 1795–96.
