[W]hy should the Palatine Boors be suffered to swarm into our Settlements and, by herding together, establish their Language and Manners, to the Exclusion of ours? Why should Pennsylvania, founded by the English, become a Colony of Aliens, who will shortly be so numerous as to Germanize us instead of our Anglifying them, and will never adopt our Language or Customs any more than they can acquire our Complexion?Which leads me to add one Remark, that the Number of purely white People in the World is proportionably very small. All Africa is black or tawny; Asia chiefly tawny; America (exclusive of the new Comers) wholly so. And in Europe, the Spaniards, Italians, French, Russians, and Swedes, are generally of what we call a swarthy Complexion; as are the Germans also, the Saxons only excepted, who, with the English, make the principal Body of White People on the Face of the Earth. I could wish their Numbers were increased. And while we are, as I may call it, Scouring our Planet, by clearing America of Woods, and so making this Side of our Globe reflect a brighter Light to the Eyes of Inhabitants in Mars or Venus, why should we, in the Sight of Superior Beings, darken its People? Why increase the Sons of Africa, by planting them in America, where we have so fair an Opportunity, by excluding all Blacks and Tawneys, of increasing the lovely White and Red? But perhaps I am partial to the Complexion of my Country, for such Kind of Partiality is natural to Mankind.
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.…[F]oreigners 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? There may, as to particular individuals, and at particular times, be occasional exceptions to these remarks, yet such is the general rule. The influx of foreigners must, therefore, tend to produce a heterogeneous compound; to change and corrupt the national spirit; to complicate and confound public opinion; to introduce foreign propensities. In the composition of society, the harmony of the ingredients is all-important, and whatever tends to a discord ant intermixture must have an injurious tendency.
Had it all been true, prudence requires us to trace the history further and ask what has become of the nations of savages who exercised this policy, and who now occupies the territory which they then inhabited? Perhaps a lesson is here taught which ought not to be despised.
