This paper examined Hemingway's depiction of Brett Ashley and Jake Barnes in his The Sun Also Rises (1926) by using Simone De Beauvoir’s existentialist feminism. De Beauvoir's theory is employed to decide if the female character depicted as ‘other’ or not? Besides, it is used to analyze these characters from a gender-based point of view. This analysis showed evidence of female empowerment against male dominance and orientates the readers at examining the two characters on the aspect of subversion of gender roles. In doing so, this paper maintained the essence of De Beauvoir’s idea within the novel where women have to focus on themselves and should have their own choices, regardless of any external forces that subdue these women into performing an assigned, stereotypical gender role.
