When proper allowance has been made for geographical exigencies, another more purely moral and social consideration offers itself. Experience proves that it is possible for one nationality to merge and be absorbed in another; and when it was originally an inferior and more backward portion of the human race, the absorption is greatly to its advantage. Nobody can suppose that it is not more beneficial to a Breton, or a Basque of French Navarre, to be brought into the current of the ideas and feelings of a highly civilized and cultivated people--to be a member of the French nationality, admitted on equal terms to all the privileges of French citizenship, sharing the advantages of French protection, and the dignity and _prestige_ of French power--than to sulk on his own rocks, the half-savage relic of past times, revolving in his own little mental orbit, without participation or interest in the general movement of the world. The same remark applies to the Welshman or the Scottish Highlander as members of the British nation. Whatever really tends to the admixture of nationalities, and the blending of their attributes and peculiarities in a common union, is a benefit to the human race. Not by extinguishing types, of which, in these cases, sufficient examples are sure to remain, but by softening their extreme forms, and filling up the intervals between them. The united people, like a crossed breed of animals (but in a still greater degree, because the influences in operation are moral as well as physical), inherits the special aptitudes and excellences of all its progenitors, protected by the admixture from being exaggerated into the neighboring vices. But, to render this admixture possible, there must be peculiar conditions. The combinations of circumstances which occur, and which effect the result, are various. The nationalities brought together under the same government may be about equal in numbers and strength, or they may be very unequal. If unequal, the least numerous of the two may either be the superior in civilization, or the inferior. Supposing it to be superior, it may either, through that superiority, be able to acquire ascendancy over the other, or it may be overcome by brute strength and reduced to subjection. This last is a sheer mischief to the human race, and one which civilized humanity with one accord should rise in arms to prevent. The absorption of Greece by Macedonia was one of the greatest misfortunes which ever happened to the world; that of any of the principal countries of Europe by Russia would be a similar one.
