  The effects of this diversity movement would be felt more in the 1990s and beyond. In the meantime, in the 1970s and 1980s feminist theory began to develop in the various areas of the social sciences and humanities, and in philosophy it began to arise in what were already the different traditions and areas of research. As a branch of political philosophy, feminist political philosophy has often mirrored the various divisions at work in political philosophy more broadly. Prior to the fall of the Berlin Wall and the end of the Cold War, political philosophy was usually divided into categories such as liberal, conservative, socialist, and Marxist.  Except for conservatism, for each category there were often feminists working and critiquing alongside it. Hence, as Alison Jaggar’s classic text, Feminist Politics and Human Nature, spelled out, each ideological approach drew feminist scholars who would both take their cue from and borrow the language of a particular ideology (Jaggar 1983). Jaggar’s text grouped feminist political philosophy into four camps: liberal feminism, socialist feminism, Marxist feminism, and radical feminism. The first three groups followed the lines of Cold War global political divisions: American liberalism, European socialism, and a revolutionary communism (though few in the west would embrace Soviet-style communism). Radical feminism was the most indigenous of the feminist philosophies, developing its own political vocabulary with its roots in the deep criticisms of patriarchy that feminist consciousness had produced in its first and second waves. Otherwise, feminist political philosophy largely followed the lines of traditional political philosophy. But this has never been an uncritical following.  As a field bent on changing the world, even liberal feminist theorists tended to criticize liberalism as much or more than they embraced it, and to embrace socialism and other more radical points of view more than to reject them. Still, on the whole, these theorists generally operated within the language and framework of their chosen approach to political philosophy.
