Advancing themselves through education
Explanation:
In his address at the Atlanta 1985 Exposition, Booker. T. Washington urged African Americans to seek education in order to improve their lives and the lives of their families, to gain economic power, social status, and finally, political influence.
Booker T. Washington believed that the movement for civil rights should advance slowly, by first, focusing on education. He thought that once blacks were well-educated and productive members of society, the prejudices that many White Americans held against them would fade, and this would lead to their acceptance in American mainstream society.
He particularly emphasized the importance of technical education, because he thought that industry was the most important source of jobs for black people. However, he also thought a liberal arts education was important, and he hoped that one day African Americans would receive the same quality liberal arts education that White Americans received.
