One purpose of Cooper's essay "The Higher Education of Women" was to show the importance of education in advancing a more equal society.
Anna Julia Cooper believed that intelligent women’s voices brought balance to the struggle for human rights. She strongly protested against the disparities between boys’ and girls’ curricula and the availability of financial assistance for boys but no matching funds for girls. Cooper entered Oberlin College in Oberlin, Ohio in 1881 and learnt that it offered a “Ladies” course, an experiment in educational access that was inferior to the classical course offered to men.
