De Beauvoir portrays a kind of existential story of a woman's life: an account of how a woman's attitude towards her body and real capabilities change over time over the years, and how society influences this attitude. There are even more similar events in the life of a developing young woman that reinforce the belief that it is unfortunate to be conceived with a female body. The correlation between body and brain helps clarify the oppression of women. In conclusion, the theory subscribed to by Beauvoir and Sartre is the central definition of existentialism. There is some clarification on The Second Sex simply as Beauvoir's use of Sartre's existentialism for the question of women. Further challenging the generalization that rationality is the creation of white European men alone. However, the dark memory and acceptance of the traditional female role are sufficient proof of the social positioning of women, which places them below average.
