Feminist criticism broadly examines how literature reinforces or undermines the oppression of women. It acknowledges that feminism includes diverse views and approaches. Key concerns of feminist criticism include the use of masculine pronouns that exclude women, a lack of female authors in literary canons, and how medicine and laws have historically neglected the experiences of women. Feminism argues that women's social position of inferiority has been a social construction used to keep women powerless, rather than a result of biological differences between men and women.
