“The Second Sex” is Simone de Beauvoir’s famous philosophical treatise, which became one of the fundamental texts of 20th-century feminist thought. In this work, the author investigates the position of women in society, analyzing the historical, social, and cultural factors that determine gender inequality. Beauvoir explores how women were constructed as the “Other” in relation to men and calls for a re-evaluation of feminine identity and liberation from patriarchal stereotypes.
