The claim to a national culture in the past does not only rehabilitate that nation and serve as a justification for the hope of a future national culture. In the sphere of psycho-affective equilibrium it is responsible for an important change in the native. Perhaps we haven't sufficiently demonstrated that colonialism is not satisfied merely with holding a people in its grip and emptying the native's brain of all form and content. By a kind of perverted logic, it turns to the past of the oppressed people, and distorts, disfigures, and destroys it. This work of devaluing pre-colonial history takes on a dialectical significance today.
