The interest, or apparent and supposed interest of the king or aristocracy, is to permit no censure of themselves, at least in any form which they may consider either to threaten their power or seriously to interfere with their free agency.

Context

“The interest of the king and of the governing aristocracy is to possess and exercise unlimited power over the people; to enforce, on their part, complete conformity to the will and preferences of the rulers. The interest of the people is to have as little control exercised over them in any respect as is consistent with attaining the legitimate ends of government. The interest, or apparent and supposed interest of the king or aristocracy, is to permit no censure of themselves, at least in any form which they may consider either to threaten their power or seriously to interfere with their free agency. The interest of the people is that there should be full liberty of censure on every public officer, and on every public act or measure. The interest of a ruling class, whether in an aristocracy or an aristocratic monarchy, is to assume to themselves an endless variety of unjust privileges, sometimes benefiting their pockets at the expense of the people, sometimes merely tending to exalt them above others, or, what is the same thing in different words, to degrade others below themselves.” source
