John Stuart Mill,
On Liberty
(1869)
“ In politics it is almost a triviality to say that public opinion now rules the world. The only power deserving the name is that of masses, and of governments while they make themselves the organ of the tendencies and instincts of masses. This is as true in the moral and social relations of private life as in public transactions. Those whose opinions go by the name of public opinion, are not always the same sort of public: in America they are the whole white population; in England, chiefly the middle class. But they are always a mass, that is to say, collective mediocrity. ”
