Judith Butler
“If gender is the cultural meanings that the sexed body assumes, then a gender cannot be said to follow from a sex in any one way.� (TF 356)
I believe Judith Butler is trying to say that gender is a completely different and independent from sex. Sex is its own independent entity. If “men� follow only the bodies of males and “women� only follow the bodies of females, than their gender has nothing to do with their sex. She says that will cultural influences, one can not truly know their gender just by sex alone.
