Dehumanization is the result of an unjust order that engenders violence in the oppressors, which in turn dehumanizes the oppressed.
Because it is a distortion of being more fully human, sooner or later being less human leads the oppressed to struggle against those who made them so.
In order for this struggle to have meaning,the oppressed must not, in seeking to regain their humanity (which is a way to create it) become in turn oppressors of the oppressors, but rather restorers of the humanity of both.
This, then, is the great humanistic and historical task of the oppressed: to liberate themselves and their oppressors as well.
