The beginning of what was
to become the United States was characterized by inconsistencies in the values
and behavior of its population, inconsistencies that were reflected by its
spokesmen, who took conflicting stances in many areas; but on the subject of
race, the conflicts were particularly vivid. The idea that the Caucasian(白种人)
race and European civilization were superior was well entrenched in the culture
of the colonists at the very time that the "egalitarian" (主张平等的) republic was
founded. Voluminous historical evidence indicates that, in the mind of the
average colonist, the African was a heathen, he was black, and he was different
in crucial philosophical ways. As time progressed, he was also
increasingly captive, adding to the conception of deviance. The African,
therefore, could be justifiably (and even philanthropically) treated as property
according to the reasoning of slave trader and slave-holders.<
A. The duality that characterizes the consciousness of modern Black Americans is so deeply rooted that it cannot be eliminated by political action.
B. African captives who were brought to North America had learned a basic orientation toward the world which remained with them.
C. At the time of the beginning of the United States, white Americans were not aware of the contradiction between the notion of equality and the institution of slavery.
D. The influence of the slavery experience on the West Africans was more powerful than the memory of West African attitudes.
