It is only the oppressed who, by freeing themselves, can free their oppressors. The latter, as an oppressive class, can free neither others nor themselves. It is therefore essential that the oppressed wage the struggle to resolve the contradiction in which they are caught, and the contradiction will be resolved by the appearance of the new (wo)man: neither oppressor nor oppressed, but (wo)man in the process of liberation. If the goal of the oppressed is to become fully human, they will not achieve their goal by merely reversing the terms of the contradiction, by simply changing poles.
