"The safety of a republic depends essentially on the energy of a common national sentiment; on a uniformity of principles and habits; on the exemption of the citizens from foreign bias and prejudice; and on that love of country which will almost invariably be found to be closely connected with birth, education, and family. The opinion advanced in the Notes on Virginia [by Thomas Jefferson] is undoubtedly correct, that foreigners will generally be apt to bring with them attachments to the persons they have left behind; to the country of their nativity; and to its particular customs and manners. They will also entertain opinions on government congenial with those under which they have lived; or if they should be led hither from a preference to ours, how extremely unlikely is it that they will bring with them that temperate love of liberty, so essential to real republicanism?" -Alexander Hamilton, From the New York Evening Post: an Examination of the President's Message, Continued, No. VIII, 1802"
