De Beauvoir depicts a kind of existential story of a woman's life: an account of how a woman's disposition toward her body and one's actual abilities change over the years, and how society influences this attitude. There are many such occasions in the life of a developing young woman that reinforce the belief that it is a misfortune to be conceived with a female body. The correlation between the body and the brain helps clarify the oppression of women. In conclusion, the theory subscribed to by Beauvoir and Sartre constitutes the central definition of existentialism. There is some explanation of The Second Sex as simply Beauvoir's use of Sartre's existentialism for the women's question. Further questioning the generalization that rationality is the work of white European men only. However, the dark reminder and acceptance of the traditional role of women sufficiently testifies to the societal positioning of women, which places them inferior to others..
