Royalty is a government in which the attention of the nation is concentrated on one person doing interesting actions. A Republic is a government in which that attention is divided between many, who are all doing uninteresting actions. Accordingly, so long as the human heart is strong and the human reason weak, Royalty will be strong because it appeals to diffused feeling, and Republics weak because they appeal to the understanding.
Walter Bagehot (1826–1877), British economist, critic. The English Constitution, ch. 2 (1867).
Bagehot returned to this theme in ch. 3: "The best reason why Monarchy is a strong government is, that it is an intelligible government. The mass of mankind understand it, and they hardly anywhere in the world understand any other."
