The great importance of nationality in the State consists in the fact that it is the basis of political capacity. The character of a nation determines in great measure the form and vitality of the State. Certain political habits and ideas belong to particular nations, and they vary with the course of the national history. A people just emerging from barbarism, a people effete from the excesses of a luxurious civilisation, cannot possess the means of governing itself; a people devoted to equality, or to absolute monarchy, is incapable of producing an aristocracy; a people averse to the institution of private property is without the first element of freedom. Each of these can be converted into efficient members of a free community only by the contact of a superior race, in whose power will lie the future prospects of the State. A system which ignores these things, and does not rely for its support on the character and aptitude of the people, does not intend that they should administer their own affairs, but that they should simply be obedient to the supreme command. The denial of nationality, therefore, implies the denial of political liberty. The greatest adversary of the rights of nationality is the modern theory of nationality. By making the State and the nation commensurate with each other in theory, it reduces practically to a subject condition all other nationalities that may be within the boundary. It cannot admit them to an equality with the ruling nation which constitutes the State, because the State would then cease to be national, which would be a contradiction of the principle of its existence. According, therefore, to the degree of humanity and civilisation in that dominant body which claims all the rights of the community, the inferior races are exterminated, or reduced to servitude, or outlawed, or put in a condition of dependence. If we take the establishment of liberty for the realisation of moral duties to be the end of civil society, we must conclude that those states are substantially the most perfect which, like the British and Austrian Empires, include various distinct nationalities without oppressing them. Those in which no mixture of races has occurred are imperfect; and those in which its effects have disappeared are decrepit. A State which is incompetent to satisfy different races condemns itself; a State which labours to neutralise, to absorb, or to expel them, destroys its own vitality; a State which does not include them is destitute of the chief basis of self-government The theory of nationality, therefore, is a retrograde step in history. It is the most advanced form of the revolution, and must retain its power to the end of the revolutionary period, of which it announces the approach. Its great historical importance depends on two chief causes.
