Sayings of Socrates 38

Order and discipline are the most important things in an army, and without them it is impossible to have any other service of the troops than of a confused heap of stones, bricks, timber, and tiles; but when everything is in its due place, as in a building, when the foundations and the covering are made of materials that will not grow rotten, and which no wet can damage, such as are stones and tiles, and when the bricks and timber are employed in their due places in the body of the edifice, they altogether make a house, which we value among our most considerable enjoyments. 

—Xenophon, Memorabilia 3.1
