Authority and power are two different things: power is the force by means of which you can oblige others to obey you. Authority is the right to direct and command, to be listened to or obeyed by others. Authority requests power. Power without authority is tyranny.
(Jacques Maritain (1882-1973), French philosopher. "The Democratic Charter," Man and the State, University of Chicago Press (1951).)
They [women] can use their abilities to support each other, even as they develop more effective and appropriate ways of dealing with power.... Women do not need to diminish other women ... [they] need the power to advance their own development, but they do not "need" the power to limit the development of others.
(Jean Baker Miller (20th century), U.S. psychiatrist. Toward a New Psychology of Women, ch. 10 (1976).)
Anyone who has ever constructed a "new heaven" has discovered the power to do it nowhere but in his own hell.
