Nation & Nationality (Three Essays)

The nationality formed by the state, then, is the only one to which we owe political duties, and it is, therefore, the only one which has political rights. I am very fond of ethnography, for it is a science of rare interest; but, in so far as I would wish it to be free, I wish it to be without political application.

In ethnography, as in all forms of study, systems change, this is the condition of progress. States frontiers would then follow the fluctuations of science.
