What duboise means by double aim in souls of black folks?

In "The Souls of Black Folk," W.E.B. Du Bois introduces the concept of "double aim" to describe the dual objectives of African Americans in the early 20th century: the pursuit of civil rights and the quest for higher education. He emphasizes the need for Black individuals to achieve both personal advancement and collective upliftment, bridging the gap between their cultural heritage and the demands of a racially stratified society. This dual focus reflects the broader struggle for equality and self-determination within the context of systemic oppression.
