Answer:
He said this to depicts the situation of his dominant view about society's perception of African Americans, thereby making a powerful emotional impression.
Explanation:
In the article originally titled "The Negro Child – His Self-Image"
When James Baldwin says “any Negro who is born in this country and undergoes the American educational system runs the risk of becoming schizophrenic.” what he meant was that African Americans have been told or taught history or educational background that has little or nothing to do about them, and the few histories about them, were more of undesirable messages, which implies that, their only significance lay in their allegiance to their white masters. Thereby, making them feel lost, ignored, and excluded from society.
Hence, he said this to depicts the situation of his dominant view about society's perception of African Americans, thereby making a powerful emotional impression.
