Context

“And violence, they say, is necessary to keep savages and criminals from annihilating our civilization. But these savages within and without Christian society, who are such a terror to us, have never been subjugated by violence, and are not subjugated by it now. Nations have never subjugated other nations by violence alone. If a nation which subjugated another was on a lower level of civilization, it has never happened that it succeeded in introducing its organization of life by violence. On the contrary, it was always forced to adopt the organization of life existing in the conquered nation.” source
