“Nobility is defined by the demands it makes on us — by obligations, not by rights.”

Chap. VII: Noble Life And Common Life, Or Effort And Inertia
The Revolt of the Masses (1929)
Context: Nobility is defined by the demands it makes on us — by obligations, not by rights. Noblesse oblige. "To live as one likes is plebeian; the noble man aspires to order and law" (Goethe). The privileges of nobility are not in their origin concessions or favours; on the contrary, they are conquests. And their maintenance supposes, in principle, that the privileged individual is capable of reconquering them, at any moment, if it were necessary, and anyone were to dispute them.… It is annoying to see the degeneration suffered in ordinary speech by a word so inspiring as "nobility." For, by coming to mean for many people hereditary "noble blood," it is changed into something similar to common rights, into a static, passive quality which is received and transmitted like something inert. But the strict sense, the etymon of the word nobility is essentially dynamic. Noble means the "well known," that is, known by everyone, famous, he who has made himself known by excelling the anonymous mass.… "Nobility" does not appear as a formal expression until the Roman Empire, and then precisely in opposition to the hereditary nobles, then in decadence.
