Famous quotes containing the word development:
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
“Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.”
—Womens Liberation Workshop, Students for a Democratic Society, Radical political/social activist organization. Liberation of Women, in New Left Notes (July 10, 1967)
“Ultimately, it is the receiving of the child and hearing what he or she has to say that develops the childs mind and personhood....

—Mary Field Belenky (20th century)
