John Stuart Mill about “Diversity”
“Free institutions are next to impossible in a country made up of different nationalities. Among a people without fellow-feeling, especially if they read and speak different languages, the united public opinion, necessary to the working of representative government, cannot exist.
The influences which form opinions and decide political acts are different in the different sections of the country. An altogether different set of leaders have the confidence of one part of the country and of another. The same books, newspapers, pamphlets, speeches, do not reach them. One section does not know what opinions, or what instigations, are circulating in another.
The same incidents, the same acts, the same system of government,affect them in different ways; and each fears more injury to itself from the other nationalities than from the common arbiter, the state. Their mutual antipathies are generally much stronger than jealousy of the government. That any one of them feels aggrieved by the policy of the common ruler is sufficient to determine another to support that policy.
Even if all are aggrieved, none feel that they can rely on the others for fidelity in a joint resistance; the strength of none is sufficient to resist alone, and each may reasonably think that it consults its own advantage most by bidding for the favor of the government against the rest.”
