No tribe unites with another of its own free will.

The German Fuhrer, as I have consistently maintained, is an evolutionist; he has consistently sought to make the practices of Germany conform to the theory of evolution.

There are the further difficulties of building a population out of a diversity of races, each at a different stage of cultural evolution, some in need of restraint, many in need of protection; everywhere a bewildering Babel of tongues.

It is just because civilization is ever evolving, changing, and becoming more complicated, that experts find it so difficult to define it in explicit terms.
