Government, by James Mill, Encyclopædia Britannica, 1820
Discusses the purpose of government, the means for attaining that end and various related questions and objections; rationalises that representative democracy, as exhibited in early 19th century Britain, is most conducive to "good Government"

If this great right is not to be left free and open to all, then each man's whole right, as a reasoning human being, to 'liberty and the pursuit of happiness,' is denied him."
