The nobility, say nobles, serves as intermediary between king and people. True, just as the hound serves as intermediary between hunter and hares.
 
[«La noblesse, disent les nobles, est une intermédiaire entre le roi et le peuple…» Oui, comme le chien de chasse est un intermédiaire entre le chasseur et les lièvres.]

Nicolas Chamfort (1741-1794) French writer, epigrammist (b. Nicolas-Sébastien Roch)
