Some of the central lessons that 'culture' feminism has had to inject in other places (e.g. Gilligan's criticism of Kohlberg, or Fox-Keller's of abstraction as dominance) are that:
independence is not in-and-of-itself good (roles are ok, when they are fairly chosen),
mutual dependency is not automatically ambiguous or complex (a fair family structure is natural to humans),
a lot of what we believe is in order to agree with other people, which doesn't make it false (culture is ok, and is not a war) and
the choice of those people seems free, but is often really about power (interpersonal dynamics happen and are not evil, nor are they blameworthy 'lower motives').
(None of these are deep, or inaccessible in the writings of men, but they clash with components of the male role, based on defending boundaries, negotiating hierarchy, and seeming to make one's own decisions. So they fall out of theories, or they take pernicious, confrontational forms as in Marx or the Frankfurt School.)
Consider how long it took epistemology to get to Wittgenstein's notion of language-games, which after failing at a more forthright sort of logical positivism, finally injects a lot of these aspects very directly into the theory of meaning: meaning is a human game, upon which we are totally dependent, based on consensus, and we play to win, but we do not win without mutual support (because then the consensus around the game breaks down and we start saying nonsense and claiming it is deep).
This whole summary is made up of those same recurring feminist principles. Can anyone be sure it is thoroughly irrelevant that he happened to be gay?
(Before I go further, apologies: If it offends you to link homosexuality and femininity, I understand, but I cannot agree -- they are not similar, but they are linked. And on other fronts, I could equally emphasize aspects that are characteristically German, Owning-class, Jewish and Catholic, though I won't because they are not relevant here. So if this makes me a bigot, I am at least an equal-opportunity bigot. After all, I am a Nietzsche fanboy.)
Maybe that means we would have gotten to this point earlier, from a history with a better mixture of masculine and feminine perspective. And maybe that means we can get a cleaner way forward from there with a more equally mixed perspective.
