During our book club week, or whatever it was, Bernie mentioned feminism in Beloved while we were discussing the themes of motherhood and self-realization and identity. Although I get the concept of reading from a feminist point of view, I really think that in the case of Beloved feminism is just assumed through the emphasis on Baby Suggs' and Sethe's motherhood and self-realization because they're women.
At some point, when you examine themes like race and gender, you just start associating the ideas of equality with a black person or a woman out of habit. I suppose that ties back in with the poetry debate about over analyzing. There are obviously intended statements about racial equality in Beloved. That's not contrived. But as for women in the novel, I'm not sure gender equality is the point.
Sethe and Baby Suggs both struggle with their identities, when Sethe is proud of saving her children without anyone's help (not without a man's help, she mentions women that helped her, too) and Baby Suggs starts her new life as a free woman. Neither of these imply self-realization in spite of men, just self-realization, like Paul D finally opening his tin can heart thingy.
And although motherhood applies exclusively to women, I did not get the impression that this aspect of female life during and after the Civil War was related to feminism in the novel. Maybe feminism in the sense that it was and is considered an important part of the female experience, but not as a power or right to be compared to men. I think that the emphasis on motherhood was just to emphasize motherhood, nothing more.
